Common problems
Slab Leak Problems We Solve
Most leaks under concrete show up as one of these long before water appears.
A warm tile that should not be
Walk the room barefoot. A warm stripe or spot, especially near the kitchen or bath, points at a hot line.
A wet edge along the wall
Moisture that wicks up at a baseboard, with no plumbing fixture nearby, is often coming from below.
Tiles that crack in a line
A new hairline crack, or a tile that rocks underfoot, deserves a look before it spreads.

Why Sealwyn
Why Homeowners Trust Sealwyn for Slab Leak Detection and Repair
Two methods before one mark
The complaint people make most about leak finding is a mark in the wrong place. For slab leak detection and repair, a second method has to agree before any tape goes down.
Options, not a pitch
Homeowners online describe $14,000 repipe quotes with no evidence behind them. With slab leak detection and repair, you see every realistic option and its price.
Cold leaks taken seriously
Hot leaks announce themselves with heat. Cold ones do not, so they need isolation and listening work, and slab leak detection and repair includes it.
Tested before we leave
Every job for slab leak detection and repair ends with the new line under pressure, so you know it holds.
Water Bill Climbing? Arrange Slab Leak Detection and Repair
Water under the floor does not take nights off. Locating it early usually keeps the repair small.

Questions
Questions About Slab Leak Detection and Repair
Something not covered here?
Put it to us by phone. Plain answers, a firm figure and nothing to sign.
Call (708) 982-5593What do slab leak detection and repair cost?
Locating the leak is typically $150 to $400, and a repair typically $1,500 to $5,800. Book slab leak detection and repair as one job and both figures are on paper before anything starts.
How do plumbers detect a slab leak?
They confirm the loss at the meter, test pressure with a gauge, separate hot from cold, isolate the failing branch, then use ground microphones and thermal imaging to find the exact spot.
Can you fix a slab leak without digging?
Often, yes. An overhead reroute leaves the slab untouched, and a tunnel reaches the pipe from outside. Opening the floor is one option among several.
Should I repipe instead of repairing a slab leak?
Rarely for a first leak in healthy pipe. Once the same old system has failed two or three times, get a repipe priced next to the cost of repairing each leak.
Is a slab leak an emergency?
Treat it as this week's job rather than tonight's, in most cases. Water keeps flowing and the ground keeps soaking, so book a test soon, and close the main if water is coming up.
