Slab Leak Repair for PEX and Copper Lines in Castle Rock, CO
Whether your home in Castle Rock, CO has modern PEX piping or traditional copper lines, our plumbers are skilled 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, ensuring a correct and durable repair no matter your pipe type.
Cold Water Slab Leak Repair in Castle Rock
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 quickly helps protect your foundation.
Slab Leak Detection in Castle Rock
We start by shutting off fixtures and watching the meter to verify a leak. Then we isolate the hot and cold lines to determine which one is leaking. Using acoustic ground microphones, we listen for the sound of escaping water through the concrete. Thermal imaging shows hot water leaks as warm areas on the floor surface.
Advanced Leak Detection Technology in Castle Rock
Our approach to effective slab leak repair includes investing in the latest 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 lets us locate leaks without guesswork, even in the varied mix of buildings across Castle Rock.
Pipe Rerouting and Repiping in Castle Rock
For more extensive damage, multiple leaks, or pipes that are too old and corroded to repair reliably, pipe rerouting is a long-term solution. This involves abandoning the leaking line under the slab and installing a new pipe through the walls or attic. This method bypasses the problem area entirely, providing a fresh, durable plumbing line. It is a common solution for aging homes in Castle Rock with original copper or galvanized plumbing.
Slab Leak Repair Cost Comparison in Castle Rock, CO
Spot repairs usually have a lower upfront cost but involve breaking concrete and repairing flooring. Reroutes cost somewhat more but avoid concrete work and future leaks in that line. Whole-house repipes are the best choice when you have had multiple slab leaks or old copper throughout. We give you clear prices for each option.

Hot Water Slab Leak Repair in Castle Rock, CO
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.

It is always best to hire a professional plumber from GFR Plumbing for slab leak detection and repair.

Yes, GFR Plumbing stands behind the quality of our work. We offer a warranty on our slab leak repairs, providing you with peace of mind. The specific terms of the warranty will be reviewed with you before any work begins.
Absolutely. Water steadily leaking under your foundation can erode the soil, leading to voids and uneven settlement, which can cause cracks in your foundation, walls, and flooring. Rocky mountain ground makes trenching for sewer and water lines harder, and lines must be buried below the local frost depth.
Warm spots on the floor, damp carpet, cracks in tile, mildew odors, the sound of running water and a water meter that moves with fixtures off are common signs. A sudden jump in your water bill is also a clue.
Many homeowner policies cover access to the leak and related water damage but not the pipe itself. We provide detailed reports to help with your claim.
Simple spot repairs often do not need a permit, but reroutes and repipes may, depending on your city. We take care of permits when required.
