Leak Detection & Repair in North Dallas

Some leaks announce themselves with a puddle. Most don’t. Water can escape inside a wall, above a ceiling or under your slab foundation for weeks before you notice a stain, a warm spot on the floor or a water bill that doesn’t make sense. Gas leaks are rarer but far more urgent, and they need a fast, careful response.

bluefrog Plumbing + Drain of North Dallas finds and fixes hidden water leaks, slab leaks and gas line leaks for homes and businesses across Frisco, Plano, Denton, Carrollton, Irving and the rest of North Dallas. Our licensed plumbers use specialized equipment to pinpoint the problem before opening anything up, then give you upfront pricing for the repair.

If You Smell Gas, Act First

Natural gas is treated with an additive that smells like rotten eggs. If you notice that odor, hear hissing near a gas line or appliance, or feel unexplained headaches, dizziness or nausea at home, follow these steps:

1. Leave the home right away with everyone, including pets. Don’t stop to open windows or look for the leak.
2. Don’t create sparks. Avoid light switches, appliances, phones, lighters and garage door openers while inside.
3. Call from outside, at a safe distance. Contact your gas utility’s emergency line, and call 911 if the odor is strong or anyone feels ill.
4. Then call a licensed plumber. Once the utility has made the area safe, we can locate and repair leaks on your home’s gas piping.

Please don’t rely on DIY checks like soapy water when you can smell gas. Leaks can be hidden behind walls, under floors or underground, and safety comes before diagnosis.

Hidden Water Leak Detection

A small leak can waste a surprising amount of water and quietly damage drywall, flooring, cabinets and framing. It can also encourage mold. The sooner the source is found, the smaller the repair tends to be.

Common Signs of a Hidden Water Leak

• A water bill that keeps rising without a change in your habits
• The water meter moving when every fixture is off
• Water stains, bubbling paint or sagging drywall on walls or ceilings
• Warped, buckled or damp flooring
• A musty odor in one area of the house
• The sound of running or dripping water inside walls

How We Find It

We start by confirming there’s a leak and isolating where it is: indoors or outdoors, hot side or cold side, supply or drain. From there, we use pressure testing, acoustic listening equipment and thermal imaging to narrow the location. That way, any opening in a wall, ceiling or floor is small and in the right place. If the leak turns out to be on the buried line between the meter and the house, our water line replacement team can repair or replace it.

Slab Leak Detection and Repair

Most North Texas homes are built on concrete slab foundations, with water lines running under or within the slab. When one of those lines leaks, the water has nowhere to go but into the soil beneath your home.

Why Slab Leaks Happen Here

Our expansive clay soil swells when wet and shrinks when dry, which puts stress on pipes under the slab. Older copper lines can wear thin, hot water lines expand and contract with every use, and hard water adds wear over time. A slab leak can also saturate the clay, and that soil movement may affect the foundation if it goes on long enough.

Signs of a Slab Leak

• Warm or hot spots on tile or wood floors
• Damp carpet or pooling water with no obvious source
• The water heater running more than usual
• New cracks in floors or interior walls, alongside other leak signs

Slab Leak Repair Options

Once we locate the leak, we explain your choices with upfront pricing:

• Direct access: Opening the slab at the leak to repair the pipe. Often practical when the leak is in an accessible area.
• Tunneling: Reaching the pipe from outside the foundation to avoid breaking interior floors, when site conditions allow.
• Rerouting: Running a new line through walls or the attic and abandoning the under-slab pipe. If you’ve had more than one slab leak, a partial or whole-home repiping project may be the better long-term choice.

Gas Line Leak Detection and Repair

Gas leaks can come from aging or corroded piping, loose or worn fittings, damaged appliance connectors, or underground lines disturbed by soil movement or digging. Because gas is invisible and flammable, finding and repairing these leaks is work for licensed professionals.

What a Gas Leak Repair Visit Includes

• System testing: We pressure test your gas piping and use electronic gas detectors to locate leaks, including those behind walls or underground.
• Targeted repair or replacement: We repair damaged sections or replace part or all of a line with code-compliant materials.
• Whole-system check: We look beyond the obvious problem to make sure no other leaks need attention.
• Utility coordination: We handle any required permits and city inspections and help coordinate with your gas company so service is restored safely.
• Prevention advice: We point out aging connectors, fittings or lines worth replacing before they fail.

What Affects the Cost of Leak Repair

No two leaks are alike, so we price after we find the problem. Key factors include where the leak is (an open wall versus under a slab), how much access work is needed, the pipe material, whether a section repair or a reroute makes more sense, and any permits or inspections required. You’ll see the price before we begin. Water damage restoration, such as drying and drywall or flooring replacement, is often a separate step, and your homeowners insurance agent can explain what your policy covers.
