If water is surfacing through a concrete floor or the meter will not stop spinning, shut off the main and call us on our 24/7 line at (934) 223-1875. Then keep the family off the wet floor.
Slab leak water damage in Selden, NY is the harm done to flooring, baseboards and walls when a pipe under or inside a concrete slab leaks. The pipe repair belongs to a plumber, and our job is drying and restoring what the water reached.
Why is my floor warm and my water bill climbing?
Those are the signs people describe first: a warm patch on the floor, a hissing sound at night, a bill that jumps with no change in use. They point to a slab leak, a break in a supply line running under or inside the concrete. Once the leak is found and stopped, slab leak water damage is the trade that dries and repairs what it soaked.
When a slab leak is an emergency
Treat it as urgent if water is visibly rising through cracks, flooring is lifting, or a hot water line is the source and the floor is too warm to stand on. A pressurized line can push gallons into the sub-slab soil and into your rooms. Close the main valve right now, open one faucet to drain the lines and keep out of the wet area.
We handle same-day calls when crews are available, including nights and weekends, once the water is shut off and the area is safe.
How the leak is located
A licensed plumber or leak detection specialist finds the exact point, using acoustic listening gear, thermal imaging, or a pressure test on the isolated line. We do not locate the pipe break ourselves. Our moisture meters and thermal imaging camera map where the water has traveled across floors and up walls, which often covers more ground than the leak itself.
That map matters if you have a hidden loss and a policy claim ahead. For related causes, see how burst pipe damage differs, since those leaks start above the slab and show up fast.
What the water does above the slab
| Floor or finish | Typical effect | Usual result |
|---|---|---|
| Engineered or solid hardwood | Cupping, lifted boards, staining | Dry with mats, or replace if it will not flatten, see hardwood floor repair |
| Ceramic or porcelain tile | Grout wicking, loose tiles, wet setting bed | Often kept, with the setting bed dried |
| Carpet over pad | Soaked pad, wet tack strip | Pad replaced, carpet lifted and dried |
| Laminate or vinyl plank | Swelling or trapped moisture | Often replaced, since moisture sits underneath |
Pre-1980 floors and what lies under them
Selden saw heavy suburban building from the early 1950s on, so a house here may be older than 1980. A pre-1980 house may have flooring, adhesive or mastic that needs testing before demolition. If we need to remove floor layers, we ask that testing be done first, and ask the Town of Brookhaven Division of Building about any rules on disposal.
Drying a slab and the rooms around it
Concrete holds water and releases it slowly, so drying can take longer than a wall cavity. Crews use air movers and LGR dehumidifiers, sometimes with injection or mat drying systems to push heat and air through flooring. Daily readings track progress, and flooring should not be reinstalled until the slab and subfloor read dry.
The process is described in more depth on our structural drying page.
Repair routes and who handles them
- Spot repair: a plumber breaks a small opening in the slab and fixes the pipe.
- Reroute: new lines run through walls or the attic, avoiding the slab.
- Repipe: when several lines are failing, the whole system may be replaced.
- Our work: extraction, drying, flooring and drywall repair, documented for your records.
We are not a plumbing or foundation company. Choose the plumber for the pipe, and let us handle the water and drying.
What goes into the cost
- Water category, which depends on the pipe and how long it ran.
- Area affected, including how far it reached under flooring.
- Materials, from hardwood to tile.
- Drying days, which are longer for concrete.
- Rebuild scope after the readings come back dry.
Call for a scope and price explained before work starts. We also serve Mount Sinai homes.
Coverage questions
A sudden break often counts as sudden and accidental damage, while a leak that went on for months may be treated as gradual. Policies also differ on whether they pay for access to the pipe. Check your policy and ask your insurer, and we will supply photos, readings and a written scope for your claim.
Stay safe until help arrives
- Close the main water valve.
- Stay off warm or wet floors, which can be hot if a hot line is leaking.
- Cut power to wet rooms only if the panel is dry and safe to reach.
- Call 911 or the utility first if you smell gas.
- Move rugs and small furniture to dry ground.
Questions we hear in Selden
Do you handle slab leak emergencies at night or on weekends in Selden?
Yes. We run 24/7 dispatch and aim for same-day response when crews are available. We cannot promise a time of arrival, but we can help you with safe shut-off steps.
Why is there a warm spot on my floor and my meter keeps moving?
Those two signs together suggest a leaking hot line under the slab. Close the main, confirm the meter stops, and call a plumber for leak location, then us for drying.
Do you fix the leak itself?
No. A licensed plumber or leak detection company repairs the pipe, and we handle the water, drying and documentation.
How long does a slab take to dry?
Longer than drywall. Expect days, with meters showing when the slab and subfloor are ready for new flooring.
Can I keep my hardwood?
Sometimes. If boards have not cupped badly and we reach them quickly, drying may save them. Otherwise replacement is the cleaner choice.
Is a slab leak the same as a flood?
No. It starts from a supply line, so it is clean water at first, whereas flood damage comes from outside water.
