Slab Leak Repair in Alpharetta
A slab leak is a leak in a water line located beneath a home's concrete slab foundation. Because the pipe is underground, the leak may not be visible at first. Instead, homeowners may notice changes in the floor, water usage, pressure, or the sound of water running when no fixtures are being used. Finding the source early can help limit water damage and avoid unnecessary disruption to the home.
Not every leak under a slab requires an emergency response, but it should not be ignored. A slow leak can continue wasting water and may cause damage to flooring or other parts of the property. If you have significant water flow, standing water, damage that is visibly spreading, or a sudden unexplained increase in water usage, treat the problem as urgent. If the signs are minor, book an inspection before the problem becomes more difficult to repair.
How We Detect a Slab Leak
Finding the leak location before opening the concrete can help avoid unnecessary damage. Depending on the situation, we use appropriate electronic, acoustic, and other non-invasive leak detection methods to identify where the water line may be leaking.
- On-site inspection of the plumbing system
- Leak detection using appropriate equipment
- Identifying the likely location of the leak
- Explaining what we found
- Providing repair options and written pricing before repair work begins
The goal is to locate the problem as accurately as possible before deciding whether concrete needs to be opened.

Repair Methods Under a Slab
The right repair depends on the location of the leak, the condition of the pipe, and the overall plumbing system.
Spot repair is often appropriate when the problem is isolated to one section of pipe — the affected area can be accessed and the damaged section repaired or replaced, provided the surrounding plumbing is still in good condition.
Pipe rerouting abandons the damaged line and routes a new water line through accessible areas of the home rather than opening the concrete slab. This can reduce the amount of concrete disruption, although the new route may require additional work around walls or ceilings.
Full repiping may make more sense than continuing with individual repairs if several sections of the plumbing system are deteriorating or repeated leaks are occurring. We explain the available options after diagnosing the leak and provide the repair price before additional work begins.
What Affects the Price?
The price depends on the detection requirements for hard-to-locate leaks, the repair method (spot repair, rerouting, and repiping each have different labor and material needs), the location and accessibility of the leak, the condition of the existing pipe, and any concrete or finishing work needed to restore the affected area.
Does Homeowners Insurance Cover the Damage?
Coverage depends on the homeowner's specific insurance policy and the circumstances surrounding the leak. Some policies may cover certain damage caused by a sudden plumbing leak, while the plumbing repair itself or damage caused by a long-term leak may be treated differently.
Check your policy or speak directly with your insurance provider before assuming a repair or restoration cost will be covered. We can provide documentation of the plumbing problem and completed work when appropriate for an insurance claim.
