Everything on this page was computed for Houston and nowhere else: the problem ranking from its Census housing profile, the seasonal risks from its NOAA station record, the coverage from its own ZIP codes. PlumbReach USA connects you to an independent local plumber; the page itself is the homework, done in public, so the call you make is an informed one.

The median Houston home was built in 1992; 32.6% of the stock predates 1980, and the pattern this metro's own data ranks first is slab leaks under concrete foundations. PlumbReach USA is a referral service, not a plumbing company: one call connects you with an independent local plumber serving your ZIP code.
Two numbers frame everything that follows: 61.2% of Houston homes are owner-occupied, and the median one was built in 1992. Ownership matters to plumbing because owners inherit their systems whole — every material decision a builder made in the 1990s or earlier is still in the walls, ageing on its original schedule. With 32.6% of homes predating 1980 and 40.0% arriving since 2000, the metro is really two housing stocks sharing one map, and they are taken separately below before the problems are ranked.
The pre-1980 districts are not a museum; they are most of the metro's working housing, and their plumbing is a patchwork in the literal sense — original runs beside renewed sections, a heater of one decade feeding fixtures of another. Across 925,676 such homes in Austin, Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, San Jacinto, Waller, no two systems share exactly the same repair history, which is why the guidance below insists on pattern over incident: in patchwork plumbing, what has already been replaced is as diagnostic as what has failed.
The newer homes also house much of the metro's renting population, and rented plumbing lives a harder life: more occupants per system in many cases, faults reported later, and maintenance decided by someone who does not live with the drip. Across Houston, 2,601,888 households depend on systems most of them did not choose, and the post-2000 stock — 1,135,798 homes — is where the tenancy share runs highest. The failures are the modern ones: cartridges, heater elements, slab-line questions. They arrive on the subdivisions' shared schedule regardless of who holds the lease.
The weather's part in this is written at HOUSTON INTERCONT AP, TX US, where an average year carries 51.84 inches of precipitation, 111.3 days at ninety degrees or more and 10.1 nights at freezing or below. Pipes experience that year as workload and as hazard in roughly equal measure — the workload in the heater's cycle count and the drains' burden, the hazard in the exposed runs and the swelling soil. The problem ranking further down is simply the housing profile above, read under this sky.
Two public records, one metro: what was built here, and what the sky does to it.
Lay the eras side by side instead: 9.9% pre-1960 (281,110 homes), 22.7% from 1960-1979 (644,566), 27.4% from 1980-1999 (778,022), and 40.0% since 2000 (1,135,798). No single era tells the story — the proportions among them do, and those proportions are different in every metro this site covers.
New-stock metros have their own signature, and Houston has it in full: most homes built since 2000, most systems young, most plumbing work a matter of waves — the heater wave, the cartridge wave, the first slab questions — arriving street by street as identical subdivisions age in lockstep. The older pockets still produce the deepest single jobs, but the metro's plumbing centre of mass sits in its newest postcodes, and every year the waves get closer together.
Second in the table, the 1980-1999 band: 778,022 homes, 27.4% of the metro. Its systems are mature rather than ancient — copper in its pinhole years in places, plastic drains still sound, first-generation cartridges wearing out in waves — and its plumbing is the schedulable kind: work that rewards being booked before it becomes urgent.
The climate column of this profile is a workload statement. 1,266 heating degree days say how long the cold half of the year keeps inlet water near its chilliest and heaters firing at their hardest; 3,288 cooling degree days say how relentlessly the hot half loads every drain and tank; 10.1 freezing nights and 111.3 hot days mark the extremes where the failures concentrate. NOAA keeps these figures at HOUSTON INTERCONT AP, TX US as thirty-year normals — which is to say, as the closest thing plumbing has to a settled forecast.
That is the whole method of this page in one section: era shares from the Census, loads from NOAA, and a problem list that is simply where the two overlap most in Houston. The services and guidance that follow are ordered by the same profile — local first, generic last.
Sequenced by this metro's own problem ranking, not by a national catalogue order.
Every leak has two addresses: where the water appears, and where it escapes. The two are often rooms apart. Detection work exists to close that distance with instruments rather than demolition — acoustic sensors, pressure gauges, tracer methods — until the escape point is known within inches. Only then does the repair begin, sized to the actual failure instead of the size of the search.
Leaks in Houston are worth finding precisely because the metro's housing stock is mixed. Lines from the 1990s run beside lines installed last year; some are copper, some galvanized at the end of its life, some plastic. A stain on a ceiling in an older Austin County home might be a pinhole two rooms away, travelling along a joist — the pattern detection exists to prevent, where the wall is opened three times and the leak is in none of them. One marked spot, one opening, and a pressure test afterwards to prove the loss has stopped for the whole system. Count it in homes if you prefer: 925,676 built before 1980, 1,135,798 since 2000, one shared system of soil and seasons.
Scale the problem by the Census count and it stays concrete: 2,839,496 housing units, each a small network of pressurised lines, each capable of losing water silently. The meters across Houston register those losses in aggregate; the detection visit exists to assign one of them to one address — in Pasadena this month, somewhere else next.
Where this service gets booked in Houston follows the map on this page: the older districts generate the deep-end work, the post-2000 subdivisions the wear-and-tear work, and the 778,022 homes in between split the difference. Telling the call center your home's build decade — most Houston owners know it within a few years — puts the right kit on the van the first time.
The supply system is a single organism, so its failures correlate. Repiping exists for the point where correlation is obvious: pressure fading, water discolouring, leaks touring the house. New runs go in PEX or copper, routed to minimise opening walls, pressure-tested before anything is closed up.
Every pipe in Houston is in one of three conditions: new enough to forget, old enough to watch, or old enough to be living on borrowed time. The stock's distribution across those conditions is the metro's building history restated — the pre-1980 districts deep in the third condition, the growth corridors still in the first — and pipe services are how individual homes move between them. A repair returns a watched system to service; a repipe promotes a borrowed-time system back to the first condition wholesale, at a stroke, for another generation. The assessment that chooses between them is short, physical and evidenced: pressure, water colour, and the repair history in the walls. From Pasadena to Pearland, the pattern repeats wherever the housing era matches.
The repair-or-renew caseload is set by one figure above the rest: 32.6% of Houston homes predate 1980, plumbed in the materials now at the end of their service lives. Around The Woodlands (116,916 residents) as in the old core, that percentage is not an abstraction — it is the street's plumbing, house by house.
In Houston this service is booked most often through the problem patterns at the top of this page — the metro's housing data, not habit, sets the order. If your home is in the 32.6% built before 1980, mention its age on the call: it changes the parts the plumber loads before heading to Houston and the rest of the metro.
The water heater is the hardest-working appliance in the house and the least observed. It cycles through every shower, wash and rinse, accumulating sediment with each firing, until its decline announces itself in the household's most intimate routines: the shower that fades, the rumble from the closet, the rust at the tap. Service reads the tank's age, its sediment and its anode, and separates the heaters with years left from the ones living on borrowed time.
Ask a Houston plumber what kills water heaters and the answer is time plus sediment: the tank heats, minerals settle, the anode rod spends itself slowing the corrosion, and eventually the steel loses. The metro's climate keeps the cycle count high — long hot seasons pull more hot water through showers and laundry than a mild climate would — so heaters here earn their keep. Owners in Austin County who flush the tank yearly and keep an eye on the anode rod are the ones whose heaters reach the far side of a decade. The 51.84 inches of rain in an average year here is part of the story too — buried lines feel every wet season.
Heater work in this metro is a fleet problem: the tanks were installed in waves with the subdivisions, and they reach their verdicts in waves too. Sugar Land (109,735 residents) sits inside one of those waves; the older districts run their own, one tank at a time, inside plumbing a generation older.
One local habit worth copying: Houston homeowners who mention their street's building era when they book get a better-matched visit, because a plumber heading to a the 1990s home in Austin County loads different parts than one heading to a slab-built subdivision in Pasadena. The service is the same; the preparation is local.
A house can survive a lot of plumbing faults, but not a failed path to the street. Sewer services confront the lateral directly — inspected by camera, cleared where clearing suffices, excavated and renewed where the pipe has structurally given up. The footage, shown to the homeowner, is the basis of every recommendation.
A lateral's enemies in Houston are patient and they are local: roots working the joints under the canopy streets of Austin County, soil that swells with 51.84 inches of yearly rain and shrinks back in the dry stretches, and plain elapsed time in the districts where the pipe predates the pavement above it. Against enemies that slow, the camera is less a diagnostic luxury than the only honest calendar the line will ever get — footage that says whether the pipe has years left, or has been spending them. The remedy scales to that verdict and to no other. That is the daily reality for the 2,601,888 households spread across Austin, Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, San Jacinto, Waller.
Under Houston lie 2,839,496 laterals, one per housing unit, and the oldest of them — beneath the 281,110 pre-1960 homes — have been underground since the metro was a fraction of its present size. The camera diary in Atascocita and the old core is written by that buried generation.
Where this service gets booked in Houston follows the map on this page: the older districts generate the deep-end work, the post-2000 subdivisions the wear-and-tear work, and the 778,022 homes in between split the difference. Telling the call center your home's build decade — most Houston owners know it within a few years — puts the right kit on the van the first time.
In Houston the emergency call is routed, not queued: one number reaches the independent local plumber covering Austin, Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, San Jacinto, Waller at that hour, and the housing record on this page — median build year 1992 — is the homework they arrive already knowing.
Drain work in Houston splits by era: the 925,676 pre-1980 homes drain through older materials, the post-2000 subdivisions through plastic — and the local plumber reads the cable's return to tell which world your street drains through.
Running, rocking or refusing — in Houston the diagnosis is the same short sequence: fill valve, flapper, supply line, flange. The plumbers routed here carry the internals for the fixtures this metro's eras installed.
Fixture work in Houston divides by era like everything else on this page: washer-era taps in the older districts, cartridge internals in the post-2000 subdivisions — the local plumber stocks for both.
Two patterns generate most of the bookings behind the services above: Slab leaks under concrete foundations and galvanized pipes at the end of their life. That is why the order of this page's service list is what it is — the services answering those patterns come early, and the rest follow in the order the metro's data supports. A homeowner whose home matches the local profile — built in the metro's big decades, in one of its older districts — is, statistically, reading their own shortlist.
Chosen by this metro's own housing and weather data — the same two records this whole page is built from.
Consider what a slab foundation asks of a water line: to be buried at the pour, unserviceable by design, and to outlast the building it serves. Most lines manage it. The ones that do not — chafed at a bend, worked by the soil's seasonal movement, thinned by decades of hot water — fail into the one medium that hides them completely. Houston's growth districts around Houston hold this arrangement by the thousand. The leak hunt therefore runs on inference sharpened by instruments: the meter's testimony, the floor's warmth, the hiss through concrete, converging on a point small enough to open.
Once a slab leak is located, the repair decision turns on geometry. Opening the floor at the marked point reaches the failed section directly and restores the original run — a good answer when the line is otherwise sound and the spot sits under replaceable flooring. Rerouting abandons the buried run entirely and carries the water through walls and ceiling instead — a better answer when the line has form, when several runs share the slab, or when the floor above is worth more than the pipe below. Plumbers in Houston argue both sides of that choice daily; the honest version depends on the leak's position, the line's history, and what the floor is made of.
The arithmetic of concealment: 1,135,798 homes built since 2000, most on slabs, joining the post-war slab tracts — a buried-line population in the tens of thousands of runs, each invisible from inside the house. Even a small annual failure rate across that population produces this metro's steady background count of slab calls.
Run two taps at once in a galvanized house and the second one apologises. That is the material's signature in old age: rust accreting inside the bore until the pipe delivers a fraction of its designed flow, weakest at the far end of the run. Houston carries 925,676 pre-1980 homes, and the ones still on original galvanized announce themselves the same way — pressure that fades year by year, water that runs tea-coloured after a quiet weekend. Repiping is simply the moment the household stops negotiating with the symptom and replaces the cause.
Galvanized pipe fails politely, which is precisely the problem. No flood, no drama — just a shower that weakens across years, a washing machine that fills slowly, water that blushes rust after holidays. Households adapt without noticing, the way you adapt to a dimming bulb. The 644,566 homes built in this metro between 1960 and 1979 stand in the front of that queue now, their original steel bores narrowed to drinking-straw width in the worst runs. The fix, when it comes, tends to astonish people — not with its scale, but with the pressure they had forgotten they were owed.
Count it by era rather than by street: the metro's homes built between the war years and 1980 — the heart of the galvanized period — number in the tens of thousands here, and the 925,676 pre-1980 homes overall are the pool this problem draws from. Plumbers working Houston and the older districts can often date a home's pipework from the kerb, because the building booms that raised those neighbourhoods plumbed them all the same way.
A water heater under strain complains in a consistent order. First the recovery slows: back-to-back showers end in a lukewarm truce. Then the noises begin — sediment on the tank floor superheating pockets of water into small, kettle-like pops. Then the pilot or the elements start their intermittent failures. In Houston the strain is structural: 3,288 cooling degree days of demand against 1,266 heating degree days of cold inlet water, cycling the metro's tanks without an off-season. Servicing interrupts the order at whichever stage it has reached; the tank's age and the sediment's depth decide whether the interruption is a repair or a retirement.
A water heater's enemies compound quietly. Sediment settling on the tank floor insulates the water from the burner or elements, so the unit fires longer to do the same work; the longer firing expands and contracts the tank steel, working the lining; the anode rod, designed to corrode in the steel's place, spends itself a little faster with every cycle. None of this announces itself until recovery slows — showers running lukewarm in sequence, a rumble from the tank as steam pockets form in the sediment — and by then the arithmetic of age has usually been running for years. Homes in Houston put real hours on these appliances: hot water is not a seasonal luxury here but a year-round daily load, and the fleet of heaters across the metro ages in step with the housing that holds it.
Scale the problem by the metro's own numbers: 2,601,888 households, each cycling a tank through 3,288 cooling degree days of heavy summer demand and 1,266 heating degree days of cold incoming water. That is a workload measured in millions of heating cycles a year across Houston — and sediment, the main product of all that work, never leaves the tank unless someone drains it out.
A lateral ages in the dark, and its ageing has a geography. The run beneath the house is sheltered; the run beneath the yard takes the soil's full behaviour — swelling after Houston's 51.84 inches of yearly rain, shrinking in the dry months, shifting at every joint. Add the trees, whose roots read those joints as invitations, and the lateral's condition at any address is a sum of its material, its soil and its canopy. The camera reads the sum directly, which is why sewer advice here starts with footage: the remedy for a rooted joint and the remedy for a settled belly share no resemblance.
The lateral is the hardest-working pipe a household owns and the only one nobody ever sees. It carries everything, it was buried once and forgotten, and its condition depends on decisions made the year the house was built: the material chosen, the slope it was laid at, the soil it was bedded in. Ageing laterals fail in characteristic ways — joints offset as soil settles, bellies where the bedding washed or sagged, walls thinned by decades of flow. The house above reports these failures indirectly, through its ground-floor fixtures, which is why a sewer problem so often gets mistaken for a simple clog at first. In Houston, where whole districts were built in the same few decades, laterals are ageing on a shared timetable — the line under one house is a fair guide to the line under its neighbour's.
The depth of the bench matters locally: this is not a pattern confined to a few old streets. Every district built before modern plastic — the core, the post-war rings, the middle suburbs — holds laterals of the same generations, and the metro's own growth means their combined length runs to thousands of miles of buried, jointed, ageing pipe. The ranking reflects that inventory, nothing more exotic.
Sewer joints were never sealed against biology; they were sealed against water, and only just. A clay or iron joint weeps a breath of moisture into the surrounding soil, and roots — which exist to find exactly that breath — arrive over seasons as fine hairs, then threads, then a woven mass that fills the bore. In Houston the oldest lines run under the oldest trees, around Houston and the established districts, so the pattern's geography is the geography of the mature canopy. The line does not need to be broken to be invaded; it needs only to be jointed, buried and old, in the company of trees.
Roots do not break into pipes; they are invited in. A joint in a clay or cast iron line breathes out a trace of moisture vapour, and a nearby tree's root hairs — which exist to find exactly that signal — grow toward it and through any gap the joint presents. Inside the pipe the roots find water and nutrients year-round, so they thicken, branch, and begin to trap everything the household sends down: paper, grease, solids. The first symptom is usually a slow main line that clears and returns on a cycle, because a cable can shred the root mass but cannot remove the joint it entered through. The pattern is seasonal in its own way — roots grow hardest in spring — and it belongs to streets where trees and jointed pipes have shared the same ground for decades, as they have across much of Houston.
The metro's own canopy is the co-defendant: established neighbourhoods pair mature street trees with jointed clay and iron laterals of the same vintage. Root calls concentrate exactly where those two maps overlap — a correspondence visible in any local plumber's records and predictable from the Census-era map of the older districts.
Storm season changes the plumbing risks in Houston. Heavy rain pushes groundwater up around buried lines and can flood low-lying drainage, and homes here learn which of their drains sit at the bottom of the system the hard way — a floor drain or a basement fixture is where a surcharged line shows first. Before the season, it is worth knowing how your home behaves: whether the yard drains toward or away from the house, whether the sewer cleanout cap is sound, and where the main water shutoff is if a line is damaged. After a major storm, running every drain and watching the ground-floor ones tells you within minutes whether the line is moving water normally again.
When the storms come, Houston's plumbing meets them in the ground: laterals under saturated soil, cleanouts under standing water, ground floors at the level the water is looking for. The season tests the buried half of every system here, and it tests the older districts — where the lines are jointed clay and iron — hardest of all. Preparation is unglamorous and specific: know the cleanout, know the shutoff, know the ground-floor drain in the house.
What makes the slab leak the defining pattern of the growth-era metro is the combination of concealment and consequence. Concealment, because the line is entombed: no crawl space to inspect, no basement ceiling to stain. Consequence, because the escaping water undermines the very ground the slab rests on and feeds the heater a second, phantom household to supply. Houston's slab stock spans both the post-war tracts and the 1,135,798 homes built since 2000 — the pattern crosses eras wherever the concrete does — and its detection has become a small science of meters, microphones and thermal cameras precisely because eyes are useless here.
The numbers underneath it, for Houston: 2,839,496 housing units, a median build year of 1992, and a climate record at HOUSTON INTERCONT AP, TX US of 1,266 heating degree days against 3,288 cooling degree days. Cross the housing record with the weather record and this pattern is what falls out at the top — rarely the most dramatic problem in plumbing, but the one this metro's stock and climate manufacture most steadily.

A metro is a federation of building decades wearing one name, and the grid above is Houston's federation: Houston at the centre, Pasadena (149,345 residents) and Pearland (125,983) in the next ring, and the smaller communities beyond, down to places a few thousand households deep. What unites them is one climate record and one routing; what divides them is the year their streets were plumbed. The ZIP list that follows is the practical definition of that federation — if your code is on it, your home's era is part of the data this page was built from.
Beyond the largest communities sit The Woodlands (116,916), League City (114,885), Sugar Land (109,735), Conroe (96,976), Atascocita (93,926) — smaller places across Austin, Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, San Jacinto, Waller, covered on the same terms. Their housing tends to be older on average than the big suburbs', and their calls follow the older patterns on this page. One routing covers them all: find your ZIP code below and the rest is a phone call.
Start with Houston itself: 2,300,419 residents, 31.6% of the metro — the centre the rest of the map orbits. Pasadena (149,345) and Pearland (125,983) form the next ring out, housing with its own building decades and its own plumbing generations. Beyond them the metro thins into the smaller communities in the grid above, each a few thousand households deep — small in population, identical in one respect: their pipes answer to the same eras and the same weather as the big city's.
One metro, 10 county lines drawn through it: Austin, Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, San Jacinto, Waller. The lines are invisible to the water and the weather, but they structure everything administrative around a plumbing job — which office permits it, which inspector signs it, which code edition applies. Austin County, at the centre, carries the oldest housing and the heaviest share of the work this page describes; its neighbours carry the growth. A routed local plumber navigates the patchwork so the homeowner does not have to.
Three neighbouring coverage areas begin where this one ends: Beaumont, TX, some 77 miles off; College Station, TX, 89 miles; and Austin, TX, 137 miles. Each keeps its own page because each keeps its own numbers — a different median build year, a different climate station, a different problem ranking. Boundary households should trust the ZIP list over the map: the code, not the compass, assigns the dataset.
Set Houston among its neighbours and the contrasts sharpen the profile: Beaumont, TX — metro population 399,310, median build year 1979 — sits 77 miles away; College Station, TX (287,476, median 1994) 89 miles; Austin, TX (2,620,945, median 2000) 137 miles. Three different housing stocks under three nearby skies, which is why each keeps its own page and its own problem ranking rather than borrowing this one.
Ratios tell the metro's story compactly. Renters occupy 38.8% of homes; owners hold the rest. For every home built since 2000 there are 0.8 from before 1980. Spread the stock across the coverage map and each ZIP code carries about 11,685 housing units — the density at which era patterns repeat street after street instead of scattering, and at which a routed round of calls stays inside a few districts.
The Houston record in one line — median home age: 34 years · owner-occupied homes: 1,592,355 · renter-occupied homes: 1,009,533 · pre-1960 homes per covered ZIP code: 1,157 · heating-to-cooling degree-day ratio: 0.39 · average rainfall: 1,317 mm a year.
