Emergency Slab Leak Repair in South Portland, ME
A major slab leak can push water up through flooring or into walls quickly. We help you shut off the water and send a technician to isolate the leaking line. Often we can restore water to the rest of the house while we plan the repair. Prompt action limits flooring damage and soil saturation.

Advanced Leak Detection Technology in South Portland
Our approach to effective slab leak repair includes investing in modern diagnostic technology. We use equipment such as thermal imaging cameras to detect temperature changes caused by leaking hot water lines, and highly sensitive acoustic sensors to listen for the sound of escaping water. This technology allows us to locate leaks without guesswork, even in the varied mix of buildings across South Portland.
Hot Water Slab Leak Repair in South Portland, ME
Hot water lines leak under slabs more often than cold lines because heat expands and contracts the pipe against concrete and gravel. Mineral scale and constant recirculation can wear the pipe wall faster. We repair the leak or reroute the hot line, and we can adjust recirculation pumps to limit wear. Warm floors and higher gas or electric bills are common signs.
Slab Leak Repair for PEX and Copper Lines in South Portland, ME
Whether your home in South Portland, ME has modern PEX piping or traditional copper lines, our plumbers are proficient in repairing both. Pinhole leaks are common in older copper due to corrosive soil conditions and water chemistry, while PEX can sometimes suffer from installation issues or rodent damage. We carry a full range of parts and tools for both materials, making for a correct and durable repair no matter your pipe type.
PEX Repiping for Slab Leaks in South Portland, ME
If multiple slab leaks indicate a systemic issue with your home's original plumbing, a full PEX repipe might be the most cost-effective and durable solution. PEX tubing is flexible, corrosion-resistant, and less prone to leaks caused by foundation shifts, making it a good choice for many homes. We can replace all the water supply lines in your South Portland home, providing a brand-new, leak-free plumbing system that will last for decades.
Slab Leak Pipe Rerouting in South Portland
For more complex or recurring slab leaks, or when the original piping is badly deteriorated, pipe rerouting is an effective long-term solution. This method involves abandoning the leaky pipe under the slab and installing new plumbing lines through walls or the attic, bypassing the foundation entirely. This eliminates future slab leak risks from that particular line and is often preferred for older homes in South Portland with aging copper or galvanized pipes.
Cold Water Slab Leak Repair in South Portland
Cold water slab leaks are harder to feel but still waste water and wet the soil. They often show up as a high water bill or a meter that moves with all fixtures off. We isolate the cold line, locate the leak and repair or reroute it. Fixing cold leaks promptly helps protect your foundation.

Direct Slab Leak Repair in South Portland, ME
When a slab leak is localized and accessible, direct repair is often the most practical solution. This involves carefully jackhammering a small section of your foundation to expose the damaged pipe, then repairing or replacing the damaged section. Our technicians are skilled in careful concrete cutting and restoration, so the repair is effective and the area is properly restored. We use durable materials designed to hold up to soil movement under the slab.
