How Our Leak Detection Works

Our process is designed to find the leak with as little disruption as possible.

1. Review the Symptoms

We ask about water bills, sounds, stains, and when you first noticed the problem.

2. Test the System

We check fixtures and the water meter and pressure-test lines to confirm a leak and narrow down its location.

3. Pinpoint the Source

We use camera inspection and careful testing to trace the leak to a specific spot.

4. Recommend the Repair

We explain what we found and give you repair options. If water is actively spreading, our 24/7 emergency plumbing service can respond right away.

Signs You Need Leak Detection

Many leaks stay hidden inside walls, under floors or below the yard for weeks. Call for leak detection if you notice any of these:

  • A water bill that jumps with no change in how you use water
  • The sound of running water when every fixture is off
  • Damp spots, stains or bubbling paint on walls and ceilings
  • Warped flooring or soft spots near bathrooms and kitchens
  • A musty smell or mold in cabinets, closets or basements
  • Low water pressure that comes on suddenly
  • A water meter that keeps moving when nothing is running

Want to do a quick check yourself first? The EPA's WaterSense leak guide walks through simple ways to spot leaks at home. If you find signs of a hidden leak, call The Rooter Guys and we will track down the source.

Common Leak Detection Problems We Solve

Our leak detection service is ideal for:

  • Unexplained increases in your water bill

  • Musty odors or mold
  • Sound of running water in walls

  • Leaking water heaters and supply lines

Why Leaks Are Common in North Idaho and Spokane Homes

Our winters are hard on plumbing. Pipes in exterior walls, crawl spaces and garages freeze and crack, and the damage often stays hidden until spring when the water starts moving again. Older homes across Coeur d'Alene, Post Falls and Spokane also have aging supply lines and fittings that wear out over time, and shifting ground can stress pipes under slabs and yards.

Early leak detection keeps a small repair small. A pinhole leak found today is a quick fix. The same leak left inside a wall for a season can mean replacing drywall, flooring and insulation.

Leak Detection for Homes and Businesses

We find leaks in houses, rentals, restaurants, shops and commercial buildings. For property managers and landlords, catching a leak early protects the unit below, cuts water costs and avoids tenant callbacks.

Leak Detection FAQs

How do I know if I have a hidden leak?
Turn off every faucet and appliance, then check your water meter. If it keeps moving, water is going somewhere. A higher-than-normal water bill is another common sign.

Will you have to cut into my walls or floors?
Our goal is to find the exact spot first so any opening is as small as possible. Many leaks can be located without opening anything.

Can you fix the leak once you find it?
Yes. We handle the pipe repair as well, and if the leak is in your water heater we offer water heater repair and installation.

Do you find leaks in drain and sewer lines?
Yes. We use camera inspections to find cracks and breaks in drain lines, and we offer drain cleaning and hydro jetting when buildup is part of the problem.
