Cold Water Slab Leak Repair in Boulder
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, find the leak and repair or reroute it. Fixing cold leaks promptly helps protect your foundation.

Electronic Slab Leak Detection in Boulder
Locating a hidden slab leak requires specialized tools. Our plumbers use advanced electronic listening devices and thermal imaging cameras to pinpoint the exact location of the leak under your concrete foundation. This precision detection minimizes the need for extensive concrete removal, saving you time and money. We can detect leaks in both hot and cold water lines, as well as sewer lines, for a thorough diagnosis of your Boulder home.

Advanced Leak Detection Technology in Boulder
Our commitment to effective slab leak repair includes investing in the latest diagnostic technology.

This technology lets us locate leaks without guesswork, even in the diverse mix of buildings across Boulder.
Slab Leak Repair Cost Comparison in Boulder, 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 written prices for each option.

GFR Plumbing provides complete commercial slab leak repair services, tailored to the specific needs of your business. We work quickly to diagnose and fix the problem, so your commercial property in Colorado can return to normal operations with minimal interruption while staying safe and compliant.
Slab Leak Detection in Boulder
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.

PEX Repiping for Slab Leaks in Boulder, CO
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 strong choice for many homes. We can replace all the water supply lines in your Boulder home, providing a brand-new, leak-free plumbing system that will last for decades.

Frequently Asked Questions About Slab Leak Repair in Boulder
Slab leak detection usually costs $150 to $450. Spot repairs through the slab usually run $1,500 to $4,000, and reroutes often range from $1,800 to $5,000. Whole-house repipes are quoted based on home size.
Yes. We provide a written workmanship warranty, and pipe and fittings carry manufacturer warranties. We explain coverage before starting work.
A simple direct slab leak repair can often be completed in a single day. More complex repairs involving pipe rerouting or extensive repiping might take 2 to 5 days, depending on the scope of work and the size of your Boulder property. We always aim for efficient service with minimal disruption.
GFR Plumbing stands behind our slab leak repair work with a comprehensive warranty on parts and labor. The specific terms of the warranty will be provided with your estimate, for peace of mind about the durability and quality of our repairs in Boulder.
Simple spot repairs often do not need a permit, but reroutes and repipes may, depending on your city. We handle permits when required.
Look for unexplained spikes in your water bill, warm spots on your floor, the sound of running water when no fixtures are in use, visible water stains or mildew on baseboards or carpets, and cracks in your foundation. These are strong indicators that you might have a hidden slab leak in your Boulder home.
Older homes in Boulder with copper or galvanized steel pipes are often more prone to slab leaks due to corrosion and material wear over time. While PEX is more flexible and resistant to corrosion, it can still develop leaks from installation errors, excessive pressure, or physical damage. Our team repairs all common pipe types.
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. Basements are common in Colorado, and shifting soil can crack floor drains, sewer lines, and foundation walls over time.
