Licensed plumbers, written pricing, based in Danbury
A water bill that climbs with no change in use, the sound of water running when everything is off, a warm patch on the floor: hidden water leaks rarely show themselves directly. Action Construction locates and repairs them for Danbury, CT homes and businesses, finding leaks behind walls, under slabs, beneath fixtures, and in buried service lines with the least demolition possible. Our work is the water side of the system. If you smell gas, leave the building and call your gas utility or 911 first.
Leak detection deals with the pressurized supply lines and the drain and waste lines that carry water through and out of your home. A suspected gas leak is a different problem and a life safety one, so that call goes to the utility emergency line rather than a scheduled plumbing visit. On the water side, a hidden leak wastes water around the clock and does slow structural damage long before it surfaces as a stain or a puddle, which is why finding it early is worth a service call.
The two questions a leak location visit answers are where the water is escaping and what it will take to reach it. Those drive the size of the repair, whether any finished surface has to come out, and whether the run that failed is a one time fault or a sign the whole branch is near the end of its life.
Hidden leaks tend to show up indirectly. Watch for a water bill that climbs with no change in use, the sound of running water when every fixture is off, warm or damp spots underfoot, staining that spreads on a ceiling or wall, a musty smell in a closet or finished basement, low pressure at the fixtures, or the water meter creeping while the house is completely still. On a well, a pump that kicks on every few minutes with no water running is the same warning sign as a moving meter on city water.
The simplest first check you can run yourself is the meter test. With every fixture and appliance off, note the meter reading, wait 15 to 30 minutes, and read it again. If the dial has moved or the low flow indicator is turning, water is escaping somewhere in the system, and it is time for a professional leak location before the damage spreads.
Once the source is confirmed we give you a written price for the repair. Because we are a general contractor we can open the wall or the slab, make the repair, and close and finish the surface on the same job rather than leave you to line up a separate contractor for the patch and paint.
Two patterns are common here. A slab leak in a home with supply pipes run under the foundation, which shows up in some Danbury era ranch construction, can undermine a floor before it is found and often shows first as a warm spot or a hairline crack that stays damp. And a buried service line leak, between the street and a city water house or between the well and an outlying house, can run for weeks under a lawn or a driveway, sometimes only showing as a soft spot or a strip of grass that is greener or grows faster.
Older homes with original galvanized supply lines also develop pinhole leaks inside finished walls as the pipe corrodes from the inside, and where one opens on a branch, more are usually close behind, so the honest conversation is often about repiping that run rather than chasing holes. If the leak has already caused an active flood, that is an emergency plumbing repair. If the source is a corroded water heater rather than a pipe, see water heater repair. A buried problem on the sewer side is covered under sewer line repair and replacement, and the full list is on our Danbury plumbing services hub.
Yes. Licensed leak detection uses acoustic ground microphones, a correlator, line tracing, and pressure testing to pinpoint a buried leak within a small area before any digging, which keeps the repair contained.
Start with the water meter. Turn off every fixture and appliance and watch the meter for 15 to 30 minutes. If it moves, water is escaping somewhere in the system, and it is time for a professional leak location before the damage spreads. On a well, watch whether the pump short cycles with nothing running.
No. A suspected gas leak is an emergency. Leave the building, avoid switches and flames, and call your gas utility’s emergency line or 911. We handle water leak detection and repair, and we can work on the plumbing side of an appliance once the utility has cleared the gas.
Usually yes. Accurate location means we open only the section over the leak. For slab leaks we can often reroute a short run overhead rather than break up a large area of floor.
That is the classic signature of a buried service line leak or a slab leak, both of which run a long time before surfacing. Book a leak location visit. Finding and fixing it early is far cheaper than the foundation, landscaping, or mold work that a long running hidden leak eventually causes.
