Every Minute a Leak Runs, the Damage Gets Worse
A water leak doesn't wait. A burst pipe floods your home in minutes. A hidden slab leak erodes your foundation for months before you notice. A slow drip behind a wall breeds mold, rots framing, and destroys drywall from the inside out. The longer a leak runs, the more expensive the damage becomes. Fast, accurate detection and professional repair are the only way to stop the destruction.
LaVergne's licensed master plumbers locate and repair every type of water leak across Whatcom and Skagit Counties, including burst pipes, slab leaks, hidden wall leaks, supply line failures, fixture leaks, crawlspace leaks, and underground water line breaks, serving homeowners throughout Bellingham, Mount Vernon, Anacortes, and surrounding areas.
What to Look for in a Leak Repair Specialist
Water leak repair requires accurate detection, proper diagnosis, and skilled repair work. A plumber who can't pinpoint the source tears open walls and floors unnecessarily. One who patches instead of properly fixing creates a repeat failure. Here's what separates a real leak specialist from a costly mistake.

Most Common Water Leaks We Repair
Water leaks happen in every part of your plumbing system, from the main line underground to the supply tubes under your bathroom sink. Some are obvious. Others hide behind walls for months, causing thousands in damage before anyone notices. Here are the four we fix most often.
Our trucks carry copper, PEX, fittings, valves, supply lines, and detection equipment so the majority of leak repairs are completed in a single visit without waiting on parts.
Under Sink Leaks
Failed supply tubes, loose compression fittings, corroded shut off valves, or cracked drain connections. We fix the source and check every connection before leaving.
Fix It →Leaking Behind Walls
Pinhole leaks in copper, failed solder joints, or burst pipes inside wall cavities. We detect, access with minimal damage, repair, and pressure test the line.
Detect →Slab Leaks
Hot or cold water lines leaking under your concrete foundation. Warm spots on floors, unexplained water bills, or the sound of running water when nothing is on.
Locate →Burst or Frozen Pipes
Pipes that freeze and split during Northwest winters, or supply lines that fail under pressure. Emergency shut off, damaged section repair, and water restored fast.

Why Professional Leak Repair Matters
Water damage is the number one insurance claim for homeowners, and most of it starts with a leak that could have been caught and fixed early. A dripping pipe behind a wall destroys framing, breeds black mold, and rots subfloor for weeks before any visible sign appears. A slab leak erodes your foundation silently. A burst pipe floods an entire floor in minutes.
Licensed plumbers use electronic leak detection, pressure testing, and camera inspection to pinpoint the exact source without tearing your home apart. They repair with proper materials, pressure test every fix, and ensure the problem is solved permanently, not just patched until the next failure.

Water Leak Repair FAQs
Common water leak questions answered by our licensed plumbing experts serving Whatcom and Skagit Counties.
How much does a water leak repair cost?
Simple fixture or supply line leaks typically run $150 to $400. Wall or ceiling leak repairs range from $300 to $800 depending on access. Slab leaks and underground line repairs can range from $1,500 to $5,000 or more depending on depth, location, and method. We always provide an upfront quote after diagnosis.
How do I know if I have a hidden leak?
Unexplained spikes in your water bill, the sound of running water when nothing is on, warm spots on floors, musty or moldy odors, discolored walls or ceilings, peeling paint, or your water meter spinning with all fixtures off are all signs of a hidden leak.
What is a slab leak?
A slab leak is a leak in a water line running underneath your concrete foundation. They are caused by pipe corrosion, ground shifting, or poor original installation. Signs include warm spots on floors, unexplained water use, or the sound of water running beneath the house.
Can you find a leak without tearing up my home?
In most cases, yes. We use electronic leak detection, moisture meters, pressure testing, and camera inspection to pinpoint the source with minimal or no demolition. We only open walls or floors when we know exactly where the problem is.
Is a water leak an emergency?
If you see active water flowing, a burst pipe, water pooling on floors, or water coming through ceilings, that is an emergency. Shut off your main water valve immediately and call us. We respond 24/7 for active water leak emergencies.
What should I do if a pipe bursts?
Shut off your main water valve immediately. If the leak is near electrical outlets or your panel, shut off the breaker too. Then call us. Do not attempt to repair a burst pipe yourself while the system is still under pressure.
Do you repair frozen pipes?
Yes. We thaw frozen pipes safely, inspect for cracks or splits caused by the ice expansion, repair or replace damaged sections, and insulate vulnerable pipes to prevent future freezing during Northwest winters.
Will my insurance cover water leak damage?
Most homeowner policies cover sudden and accidental water damage (burst pipe, failed supply line) but not gradual leaks or lack of maintenance. We provide detailed documentation of the leak source and repair for your insurance claim.
What areas do you serve?
We repair water leaks across all of Whatcom and Skagit Counties including Bellingham, Mount Vernon, Anacortes, Burlington, Sedro Woolley, Ferndale, Lynden, and surrounding areas.
