Under the floor
Why slab leak repair in Siesta Key, FL is a common call
Most Florida homes sit on concrete slabs with water lines running underneath. On a barrier island, the ground those pipes sit in works against them.
Many island homes were built between the 1960s and 1980s with copper supply lines laid in sandy fill beneath the slab. Salt in that fill and brackish groundwater nearby speed up corrosion on the outside of the pipe, while water flowing inside wears it from within. Eventually a pinhole opens, and pressurized water starts escaping under the floor.
Slab leak repair in Siesta Key, FL begins with proving the leak is there and pinpointing it, because guessing under concrete is expensive. Once we know where the pipe is failing and how it is routed, the repair options become clear.
For many island homes, rerouting the line through walls or the attic with PEX is the better long-term answer, because it takes the water supply out of the corrosive ground entirely. For others, a single precise opening and a direct repair is the right call.
Warning signs
Signs of a leak under your slab
- A warm or hot patch on a tile floor, often from a hot water line
- The sound of running water with every fixture off
- A water bill that climbs with no change in use
- Damp carpet, swelling baseboards or lifting wood flooring
- The water heater running more than it used to
- Cracks appearing in tile or the slab over a pipe route
Finding it
How we locate a slab leak
Confirm the leak
Meter and pressure tests show whether water is escaping and which line, hot or cold, is affected.
Listen through the slab
Acoustic equipment picks up the sound of water leaving the pipe beneath the concrete.
Check with thermal imaging
Hot water leaks show up as warm areas on the floor, helping confirm the location.
Mark and recommend
We mark the spot, map the pipe route and give you prices for each realistic repair.
Choosing the repair
Direct repair or reroute?
Neither is always right. We recommend based on the pipe, the floor and how you use the property.
Direct slab repair
- One leak in pipe that is otherwise in good condition
- Leak location reachable with a small, neat opening
- Flooring that can be patched or matched
- Keeps the original pipe route
Rerouting the line
- Pipe corroding along its length in salty fill
- Leak under expensive tile or hard-to-match flooring
- A history of more than one slab leak
- Rental homes where less floor work means less downtime
What happens next
After the repair
Whichever route you choose, we pressure test the system again before leaving to confirm there are no other leaks. Openings are kept small, and we explain what was found so you have a record for insurance or a future sale.
If you are not sure whether your leak is under the slab or elsewhere, start with our Siesta Key leak detection visit. Where several runs are failing, a broader repipe for your Siesta Key home may be worth considering. Every option is priced upfront, and financing is available on qualifying larger jobs.

Siesta Key questions
Slab Leak Repair in Siesta Key: common questions
Why does my tile floor feel warm in one spot?
A warm patch on a slab floor is a classic sign of a hot water line leaking underneath. The escaping water heats the concrete above it. You may also notice the water heater running more often. Turn off the water heater supply if you can and call us to confirm the leak with testing equipment.
Is rerouting better than breaking the slab?
It depends on the pipe. If the line is corroded along its length, as buried copper in salty island soil often is, repairing one spot may just lead to the next leak. Rerouting moves the supply above the slab and avoids that. If the pipe is otherwise sound, a direct repair can be quicker and cost less.
Does homeowners insurance cover slab leaks?
Coverage varies widely by policy. Some policies cover the cost of accessing the pipe and repairing resulting damage but not the pipe itself. We cannot tell you what your policy covers, but we provide clear documentation of the leak location, cause and repair that you can share with your insurer.
Can I keep using water while waiting for a slab leak repair?
If the leak is small, you can usually keep using water for a short time, but turning off the main when the home is empty limits damage. If water is surfacing through the floor or the leak is on the hot side, shut off the water heater supply too and call our 24/7 line at (941) 541-7473.
