Why do pipes let go in houses built a century ago?
Metal does not last forever. Galvanized supply lines corrode from the inside until the wall thickness fails, cast-iron drains rust through, and solder joints fatigue. Add a hundred years of pressure cycling and a renovation or two splicing modern pipe into old runs, and the weak point is usually a joint between eras.
Grant Park dates from 1882, Virginia-Highland did most of its building between 1909 and 1926, and Kirkwood had become a streetcar suburb by 1910. Houses of that age commonly keep original supply and drain lines in places nobody has looked at, which is a general pattern rather than a survey of any one street. The pipe under a 1990s kitchen remodel is often the only new section in the house.
Pressure also matters. A fixture that has always been slow, a toilet that takes an age to fill or rust flakes in the aerator all point at narrowing pipe. None of that is an emergency by itself, and all of it is worth a plumber's eye before the day it empties into your dining room ceiling.
A main broke on my street. Does that affect my house?
Usually the public break floods the street rather than your rooms, but the pressure loss and surge when a main fails or is restored can finish off an already weak joint or valve inside the house. If water appears indoors after a street break, treat it as your own plumbing until someone confirms otherwise.
Freezing weather in January 2025 broke several mains around the city, including on Peachtree Road in Buckhead and at Piedmont Avenue downtown, and January 2026 brought breaks at Alpine Road NE and Zadie Street NW that affected 50 and about 100 homes. One of those failures was in a cast-iron main laid in 1917, which tells you something about the age of the network under the older city.
Report the street side to the City of Atlanta Department of Watershed Management, or to the relevant county water authority if you are outside the city, and photograph what is happening at your own property line. The indoor cleanup runs on its own track: extract, dry, document. Do not wait for the utility to finish before starting it.
How much wall and ceiling has to be opened?
As little as will let the cavity dry. Small holes high and low in a stud bay are often enough to move air through it. A flood cut, removing the lower band of drywall across a wall, is for cavities with soaked insulation or water that sat long enough that the back of the board is gone.
Old lath and plaster complicates this. Plaster holds a great deal of water, dries slowly and cracks if it is dried too aggressively, so technicians tend to dry it patiently with lower airflow and tighter humidity control rather than opening it up. Where it has already lost its key and is bulging, it comes down.
Ceilings get judged on sag and weight before anything else. A ceiling holding water is dangerous and gets relieved deliberately from a safe position, never poked from underneath. What has to be rebuilt afterwards is measured and quoted once the framing above reads dry.
Can drying start before the plumber finishes?
Yes, as soon as the water has stopped. The valve is closed, so the pipe is not leaking while it waits for repair, and every hour of early extraction and air movement is material saved. The crew works around the plumber and the open pipe is left accessible.
The division of work is worth being clear about. A plumber replaces the failed pipe, fittings and valves and handles anything to do with pressure and gas. A restoration crew removes water, opens and dries the structure, treats what needs treating and documents the readings. Nobody at a restoration company should be offering to solder your supply line.
If a cavity has to stay open for the plumber, the drying plan is built around that opening instead of fighting it. Once the repair is tested and the water is back on, readings continue until the materials match a dry reference. Structural drying covers how that last stage is monitored and signed off.
Why can a slow leak cost more than a dramatic burst?
A burst is loud, obvious and stopped within minutes. A pinhole behind a cabinet or a cracked drain under a bathroom runs for weeks into framing and subfloor, which means rot, mold and a bigger rebuild. Long-term leaks are also commonly excluded from homeowners policies, unlike a sudden failure.
The tell-tales are undramatic: a floor that gives slightly in one spot, a cabinet base that stays dark, a musty note in one room, a water bill drifting up by a few dollars a month. In a crawl space it shows as a patch of wet clay under one bathroom, long before anything is visible inside.
Georgia policies generally cover sudden and accidental water damage and generally exclude damage that developed slowly, so the paperwork on a slow leak is harder as well as the repair. Nobody can tell you how a claim will land; what helps is finding the leak early and keeping the dated readings and photographs. Ask your agent what your own policy says about gradual damage.
