Explore Service Area →Big homes, finished basements, upstairs baths, pools and sprinklers: south Naperville has a lot of places for water to hide. We find the leak before anything gets opened.

Homes in south Naperville tend to be large, newer and packed with plumbing you cannot see.
A hidden water leak in Naperville homes like these can do expensive damage to wood floors, carpet and drywall before anyone notices. That is why we scan first and open later. A small marked opening in a finished basement costs far less to patch than a long trench of cut drywall.
Most homes on the south side were built from the 1990s through the 2010s.
Copper in the older sections, PEX in many newer homes. Copper from the 1990s can start to pinhole, and early PEX fittings can loosen. Both leak quietly inside walls long before a stain appears.
Large finished basements with wet bars, bathrooms and laundry rooms. A leak behind drywall here often shows first as a musty smell, a swollen baseboard or a carpet that feels damp near one wall.
In ground sprinklers are common, and many backyards have pools. A water line leak in Naperville IL yards can hide under lush lawns for weeks, and the water bill is often the first clue.
Many larger homes run two water heaters or a softener with a filter loop. Each one adds valves and connectors that wear out, and a drip in a closed mechanical room can go unseen for months.
Naperville buys Lake Michigan water from the DuPage Water Commission, treated at Chicago's Jardine plant. Before that, the city ran on a network of 25 wells.

Water leak detection in Naperville IL homes usually starts with a meter test, then moves to the tool that fits. Many visits cover two problems at once, like a ceiling stain and a pool that loses water.
We spend most of our Naperville time on the south side, closest to Plainfield, where homes and lots look a lot like the ones across the line.
A stain under the primary bath spreads across a two story family room ceiling. Thermal imaging and a pan flood test show a cracked shower pan, so only that part gets fixed and the ceiling below gets a small patch.
A slow drip at a wet bar supply line behind drywall. Moisture readings climb toward the cabinet, and the leak is marked within a small area, so the plumber opens one spot instead of a whole wall.
The level drops faster with the pump on. A return line leak under the deck is found with a pressure test on each line and marked on the pavers, so only a few pavers come up.
One corner of the lawn stays soggy and the bill climbs. A zone valve is stuck partly open, found by running each zone and watching the meter.
