The median New Orleans home was built in 1973; 64.7% of the stock predates 1980, and the pattern this metro's own data ranks first is ageing cast iron sewer lines. PlumbReach USA is a referral service, not a plumbing company: one call connects you with an independent local plumber serving your ZIP code.
New Orleans is a metro of 988,763 people and 397,029 households, and its plumbing is a portrait of its building history. The median home here was built in 1973; 64.7% of homes predate 1980 and 31.2% predate 1960, while 15.3% have arrived since 2000. Every one of those eras plumbed differently — different pipe materials, different drain designs, different fixtures — and they fail differently, which is why this page is organised around the patterns the data actually produces in New Orleans rather than plumbing in the abstract.
By now, most of New Orleans's pre-1980 homes are on their second plumbing lives in part: a heater replaced, a bathroom renewed, a section of drain renewed after a failure — while the remainder of the original system carries on into its sixth and seventh decades. The 299,905 homes in that stock are therefore not uniformly old; they are individually old, each with its own archaeology of repairs. That is why the pre-1980 districts reward inspection over inference: the street's average says little about the house in front of you, whose real history is written under its floors.
The post-2000 homes have a plumbing trait the older districts never had: uniformity at scale. A subdivision's lines went in within a few seasons of each other, so its first heater failures, its first cartridge failures and its first slab questions arrive within a few seasons of each other too. With 70,920 such homes in the metro, those arrivals are not anecdotes but waves, and the households who read them early — who learn their system's age and keep its number handy — meet them as maintenance rather than emergency.
One more record sits over the whole metro, and it is the one the pipes themselves keep: the weather's. NEW ORLEANS ALVIN CALLENDER FL, LA US logs 63.8 inches of precipitation in an average year and swings between 64.4 days at 90 degrees or more and 10.8 nights at or below freezing. Buried lines ride that swing in the soil; heaters ride it in their cycle counts; exposed runs ride it at the extremes. Cross the swing with the housing ages above and the selection of problems further down this page stops looking like a list and starts looking like an arithmetic result.
Housing eras and climate, joined — the two datasets every section of this page is built from.
Break the stock down by building era and the profile sharpens. Before 1960: 31.2% of homes, roughly 144,622 of them. From 1960 to 1979: 33.5%, about 155,283. From 1980 to 1999: 19.9%, about 92,243. Since 2000: 15.3%, about 70,920. Four eras, four material palettes — and the balance among them is this metro's plumbing character in a single paragraph.
The 1960-1979 band is where this metro keeps its plumbing personality: old enough for galvanized to be failing and first-generation fixtures to be wearing out, young enough that copper systems still have decades in them. Two houses of identical age on the same New Orleans street can stand on opposite sides of that divide purely by what the builder specified — which makes this the metro where assumptions fail most often, and a camera or a pressure gauge earns its keep on nearly every diagnostic visit.
The runner-up band is the oldest one: 31.2% of homes, some 144,622 of them, standing from before 1960. Plumbing in that band is heritage work — iron, clay and steel systems that have outlasted their design lives — and it punches above its share in the metro's repair diary, because age, not headcount, sets the failure rate.
Start the climate half where the water starts: underground. New Orleans's laterals rest in soil that takes 63.8 inches of rain in an average year and dries between deluges, swelling and shrinking against their joints through every season. Above ground the same record reads as workload — 2,615 cooling degree days of hot-water demand, 1,425 heating degree days of cold incoming water at NEW ORLEANS ALVIN CALLENDER FL, LA US. A plumbing system here is never in neutral; the record keeps it working at one end or the other all year.
Hold the two halves together and the rest of this page explains itself: the problems ranked highest here are the ones where New Orleans's dominant housing era and its climate record overlap. Change either dataset and the ranking changes — which is precisely why this profile is rebuilt from the records for every metro instead of carried over from the last one.
Selected and ranked from this metro's housing-age profile and climate record — not copied from another city's page.
Read a cast iron drain's age in its symptoms and the progression is orderly. First the line slows — not blocked, just reluctant, as scale roughens the bore and catches what passes. Then the complaints localise: one branch backing up, then another, as sections of the run reach their own stages of narrowing. In New Orleans's oldest districts that progression plays out across whole streets of the 1970s housing at once, because the lines were laid in the same years from the same material. The camera distinguishes the stages house by house: a bore narrowed by scale that cleaning can restore, against a wall thinned and cracked past any cleaning's help.
Look inside an old cast iron line with a camera and the failure stops being abstract. The inner wall grows rough with tuberculation — rust nodules that narrow the bore and catch everything passing. The bottom of the run, where water and grit travel, thins fastest; the top can look sound while the channel below it is nearly through. Roots enter at joints and add their own blockage. A New Orleans line of this vintage is therefore not one problem but a profile of problems along its length, and the repair that makes sense — cleaning, a section, a full replacement — is the one matched to the worst ten feet the camera finds, not the average of the whole run.
Another way to size the exposure: New Orleans's pre-1960 homes — roughly 144,622 of them — were plumbed in an era when cast iron was not a choice but the standard. Their drains have now spent sixty-plus winters and summers expanding, contracting and carrying loads their installers never pictured, which is why this pattern outranks problems that belong to younger housing.
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. New Orleans carries 299,905 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 exactly the problem — it gives a household years of small warnings that are easy to live with. The zinc coating that once protected the steel wears through, rust takes its place, and the rust grows inward like a narrowing artery. Flow to the farthest fixtures drops first. A shower that shares a line with a running tap loses its pressure. By the time the water itself runs discoloured after the house has sat quiet overnight, the narrowing is well advanced. None of this is a single emergency; it is a system reaching the end of its design life on schedule, and in New Orleans's pre-1980 neighbourhoods that schedule is arriving for whole streets at once, because the pipes went in together.
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 299,905 pre-1980 homes overall are the pool this problem draws from. Plumbers working New Orleans 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 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 New Orleans's 63.8 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.
Slope is the lateral's invisible specification. A sewer line does not need much fall — a quarter inch per foot is the classic figure — but it needs it consistently, and ageing takes consistency away: a section settles, a joint steps down, and the line develops a reach where flow slows and solids settle out. That belly then collects a little more each week, narrowing the line from the bottom up. Many a New Orleans lateral diagnosed as 'blocked' is really 'bellyed' — clearable today, certain to collect again. The camera distinguishes the two, and the distinction decides whether the household is booking a cleaning or planning a repair.
Universality is the point: every housing unit in the metro — 463,532 of them — drains through one lateral apiece, and the older half of that stock is served by lines as old as the homes above them. A component that universal, ageing on that schedule, does not need bad luck to top a problem list; it needs only time.
Roots do not break into sewer lines; they are invited. A joint that seeps a thread of moisture into the surrounding soil advertises itself to every root tip in reach, and the tip that finds it thickens season by season inside the pipe, weaving a net that catches the household's solids. In New Orleans the invitation list is written by its canopy: the established streets where trees and laterals have shared the same ground for half a century. Cutting the roots restores the line for a while; the lasting question the camera answers is what the joint that invited them looks like now.
Not every tree is an equal suspect. Fast-growing species with wide, water-hungry root systems explore the most ground, and a tree planted decades ago over a jointed line has been prospecting along it ever since — root tips follow moisture gradients measured in fractions, straight to the joint that breathes vapour. The mass a camera finds is therefore usually at a joint directly in a root run's path, which is why clearing the roots without addressing the joint is a postponement: the path stays open, the roots regrow along it, and the cycle shortens each time. Sealing or replacing the jointed section is what breaks the rhythm for good.
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 New Orleans. 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.
For New Orleans the season is measured at NEW ORLEANS ALVIN CALLENDER FL, LA US: 63.8 inches of rain in an average year, much of it capable of arriving in a single system. The homes that feel it first are the ones whose laterals were laid generations ago under the mature streets of New Orleans and the old core.
In New Orleans the pattern has an address pattern. The cast iron went under the homes built before 1960 — the streets of the old core and the first suburbs around New Orleans — and it is failing in the order those streets were built. A camera call in the historic districts is a different appointment from one in Metairie or the newer subdivisions: there, the same symptoms usually trace to something younger and simpler. Knowing which side of that line a home sits on is most of the diagnosis before the camera ever leaves the van, and it is why this page ranks the problem by the metro's pre-1960 count rather than by anecdote.
Why here and not everywhere: New Orleans pairs 299,905 pre-1980 homes with 64.4 days a year at 90 degrees or more and 10.8 nights below freezing. Every metro pairs its housing with its weather somehow; this particular pairing is what puts the pattern where it sits on this page's list, ahead of problems that dominate metros built in other decades, under other skies.
The first visit follows a short, diagnostic list — each item ruling a branch of the problem in or out:
Listed in the order this metro's housing and climate data supports.
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.
Sewer trouble in New Orleans rarely starts with the sewer. It starts with the ground-floor drain in the house misbehaving, and by the time sewage backs into a tub, the line outside has been compromised for a while — roots thickening at a joint, a belly deepening, cast iron scaling shut. The metro's older districts, where the housing predates 1960 by the thousands of homes, produce most of these calls; the established trees over those streets are both the neighbourhood's charm and its sewer lines' oldest enemy. The repair conversation here begins with a camera, not a shovel. With a median build year of 1973, most of the metro's 463,532 housing units are working through the same ageing curve.
Under New Orleans lie 463,532 laterals, one per housing unit, and the oldest of them — beneath the 144,622 pre-1960 homes — have been underground since the metro was a fraction of its present size. The camera diary in Metairie and the old core is written by that buried generation.
Every pipe material carries a lifespan, and pipe services are how a house changes generations. Sectional repair buys time on a sound system; full repiping retires a tired one, replacing choked or pitting lines wall by wall and leaving the household with pressure and water quality it may not have had in years.
Walk the older streets of New Orleans with a plumber and you will hear the housing stock dated by its pipework: galvanized behind this wall, copper of a certain vintage there, a repipe already done on the corner house. The metro's median build year of 1973 means that dating game works on half the homes in the metro. What decides any individual home's path is not the street's average but the evidence inside its own walls — pressure at the fixtures, the water's colour after a quiet weekend, the count of repairs already made. The assessment is short; the conclusion follows from it. Count it in homes if you prefer: 299,905 built before 1980, 70,920 since 2000, one shared system of soil and seasons.
Pipe work divides by era in this metro with unusual neatness: renewal conversations in the 299,905 pre-1980 homes, sectional repairs in the middle ring, and near-silence from the 70,920 post-2000 homes whose lines are still young. A call from Marrero can sit in any of the three bands; the home's build year says which before the door opens.
From New Orleans to Marrero, the heater question is the same — repair the unit or renew it — and the honest answer starts from its age against New Orleans's demand record, which this page sets out.
Emergencies in New Orleans are answered by local independents, not a dispatch centre: PlumbReach USA routes the call, and the stock it serves — 463,532 homes across 71 ZIP codes — is the stock this page profiles.
New Orleans's drains are cleared by local independents who work this stock weekly: a median build year of 1973 means most lines they open have decades of history in them, and the clearing approach is chosen for the era, not the postcode.
The meter test starts it in New Orleans as everywhere; what follows is local — knowing which of Jefferson Parish, Orleans Parish, Plaquemines Parish, St. Bernard Parish, St. Charles Parish, St. James Parish, St. John the Baptist Parish' eras hide lines in slabs, which in crawl spaces, and where the soil movement at NEW ORLEANS ALVIN CALLENDER FL, LA US's record makes joints let go.
In New Orleans, a toilet that runs all night is a water bill with a sound; the local service replaces the tired internals and checks the flange and supply while the tank is open.
In New Orleans the faucet call is often the first plumbing visit a newer home ever gets — the professionals routed here treat it as an introduction: the fixture fixed, and the home's shutoffs and heater age noted for the record.
If this page's services were ranked by New Orleans's call patterns rather than listed in catalogue order, they would come out much as they do here — because the ranking behind them is data, not habit. Ageing cast iron sewer lines leads the metro's problem table and galvanized pipes at the end of their life follows, so the services answering them lead the list. The long tail of a metro's plumbing life — fixture failures, toilet calls, the single unexplained leak — fills in the diary around them, here as everywhere.

Read the grid as a building programme spread over a century. The oldest communities sit where the metro began; the youngest are still adding streets at its edge; and Metairie and Kenner, with 138,995 and 65,113 residents, stand for the rings in between. Each ring plumbed in its era's materials, and each is now failing, wearing or holding in its era's characteristic order. The ZIP codes below draw the coverage boundary; the eras inside it draw everything else on this page — the problems ranked, the services ordered, the checks advised.
Also on the New Orleans map: Marrero (31,866), Laplace (28,480), Terrytown (25,844), Chalmette (22,447), Harvey (21,710) — communities spread across Jefferson Parish, Orleans Parish, Plaquemines Parish, St. Bernard Parish, St. Charles Parish, St. James Parish, St. John the Baptist Parish, each with housing from its own growth years. A plumber routed through PlumbReach USA to any of them is working from this same page: the metro data does not change at the city limit, but the housing on your street — its age, its materials, its soil — is what the visit is really about.
Every metro has a first city and a supporting cast, and the census figures draw the billing plainly here: New Orleans first, with 376,035 residents; Metairie second at 138,995; Kenner third at 65,113; then the long tail of smaller communities in the grid above. The billing matters less than the building dates — each of these places was plumbed in its own decade, by its own builders — but between them they account for nearly every housing era, material and failure pattern this page describes.
Draw the metro by its paperwork and it resolves into Jefferson Parish, Orleans Parish, Plaquemines Parish, St. Bernard Parish, St. Charles Parish, St. James Parish, St. John the Baptist Parish — 7 jurisdictions sharing one housing stock and one weather system. Jefferson Parish County holds the historic centre and the densest share of the older homes; the surrounding counties hold the rings of growth around it. Permits and inspections follow those boundaries even though water never does, which is part of why the plumber this page connects you to works these streets specifically.
Beyond the metro line, the nearest covered metros are Slidell, LA (40 miles away), Houma, LA (44 miles) and Baton Rouge, LA (79 miles) — separate pages, separate profiles, because their housing and weather records are their own. Homeowners near the boundary sit between two datasets; the ZIP list above, not the map's edge, decides which page was written about your stock.
Set New Orleans among its neighbours and the contrasts sharpen the profile: Slidell, LA — metro population 279,108, median build year 1995 — sits 40 miles away; Houma, LA (199,668, median 1982) 44 miles; Baton Rouge, LA (888,699, median 1989) 79 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 39.7% of homes; owners hold the rest. For every home built since 2000 there are 4.2 from before 1980. Spread the stock across the coverage map and each ZIP code carries about 6,529 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.
One line of New Orleans arithmetic — a median home 53 years old · 239,408 owner-occupied homes against 157,621 renter-occupied · 2,037 pre-1960 homes for every covered ZIP code · a heating-to-cooling degree-day ratio of 0.55 · 1,621 mm of rain in an average year.
