Slab Leak Detection and Repair in Anchorage
A leak under concrete has to be located precisely, because every inch of unnecessary opening is real cost and real disruption.

Warm spots on the floor, the sound of running water with nothing on, an unexplained bill increase, or persistent damp at the base of a wall all point to a line under the slab. We confirm it by isolating supply lines and pressure testing before we consider opening anything.
Depending on the location and the condition of the line, the fix is either a spot repair through a small opening or a reroute that abandons the failed section entirely. We explain both, with prices, before starting.
Common Problems We Handle
Warm patch on the floor
A hot water line leaking beneath the slab.
Sound of water with fixtures off
Pressurized line losing water under the concrete.
Cracking or heaving flooring
Long-term moisture beneath the slab.
Damp along a wall base
Water tracking to the edge of the slab.

Frequently Asked Questions
- Is a reroute better than opening the slab?
- Often, especially on older pipe or where access is difficult. We compare both for your situation.

- A located spot repair is a small opening, patched afterward. We tell you the size before we start.
- Could it be something else?
- Yes, and we rule out drains, appliances and exterior sources before calling it a slab leak.
