Denver Leak Detection And Repair

We find the leak before we open the wall, not after.

A water bill that climbed for no reason, a damp spot that keeps coming back, or the sound of running water with every tap closed. We locate hidden leaks in supply lines, drains, slabs, and buried water services across Denver Metro, then repair what we find.

Why It Is Hard To Find

The Leak You Can See Is Rarely The Leak That Matters

Water travels. It runs along a joist, down a stud bay, and across a subfloor before it finally shows itself somewhere else entirely.

By the time a stain appears on a ceiling, the actual break can be many feet away and on a different level of the house. That is why the expensive mistake in leak repair is not the repair. It is opening three walls looking for something that turned out to be behind the fourth.

Leak detection is the work of narrowing the location down before anything gets cut. We isolate which system is losing water, confirm it with a pressure test, then locate the point of loss with acoustic and thermal equipment. The opening we make is the opening we need, and nothing more.

Symptoms

Signs You Have A Hidden Water Leak

Any one of these on its own is worth checking. Two together usually means water is escaping somewhere you cannot see.

  • A water bill that climbed with no change in usage
  • The sound of running water with every fixture closed
  • A damp spot or stain that returns after you dry it
  • Warm or unusually cold patches on a floor
  • Musty smell in a room, closet, or crawl space
  • Paint or drywall bubbling, or baseboard swelling
  • Water pressure that dropped across the whole house
  • Cracked or lifting tile with no impact damage
  • A patch of lawn that stays green through a dry stretch
  • Soil that is soft or sunken near the foundation
  • Mold appearing in a room with no visible water source
  • The water meter moving with all water shut off

Check It Yourself First

The Water Meter Test Takes Fifteen Minutes

Before you call anyone, this tells you whether you have a leak at all and roughly where it sits.

Shut off every fixture

No taps running, no toilets filling, no dishwasher or washing machine, no irrigation. Tell everyone in the house to leave the water alone for the next fifteen minutes.

Read the meter

Find the water meter, usually in the basement near where the service enters, or in a pit near the curb. Most have a small triangular or star shaped low flow indicator that spins on any movement at all. Note the reading.

Wait, then read it again

If the low flow indicator is turning, or the reading changed after fifteen minutes with nothing running, water is leaving the system somewhere.

Narrow it down

Close the main shutoff inside the house and repeat the test. If the meter still moves, the leak is in the buried service line between the meter and the house. If it stops, the leak is inside.

That single step, testing with the main open and then closed, separates an indoor repair from a buried water line repair. It is the first thing we ask about when you call, and knowing the answer already saves time on the visit.

How We Find It

Four Ways To Locate A Leak Without Demolition

Which method we reach for depends on what the isolation test told us, and most jobs use more than one.

Pressure isolation testing

We isolate sections of the system and pressurize them individually to find which run is losing pressure. This is the step that turns a whole house problem into a single suspect line, and it is what makes everything after it fast.

Acoustic listening

Pressurized water escaping through a small opening makes a distinct sound that carries through pipe, soil, and concrete. Ground microphones and contact sensors let us follow that sound to its loudest point, which is the leak.

Thermal imaging

A hot water leak warms the material around it and a cold water leak cools it. A thermal camera reads those differences through finished surfaces, which is particularly useful for leaks under a slab or inside a wall cavity.

Camera inspection

For drain and sewer side leaks, where nothing is under pressure, we send a camera down the line. That shows breaks, offset joints, root intrusion, and bellies directly, and it gives a footage mark to dig or cut at.

Straight Answers

Where Leaks Actually Happen In Denver Homes

Five situations that cover most of the calls we take.

The Buried Water Line Between The Meter And The House.

The service line runs underground and nothing about a leak on it is visible indoors. Signs are a green patch of lawn in dry weather, soft ground near the foundation, a meter that turns with the house main closed, and pressure that dropped everywhere at once. Older galvanized and early polybutylene services are the usual candidates. Repair is either a spot repair at the break or a full replacement, and which one makes sense depends on the pipe material and its condition.

A Slab Leak Under The Floor.

Less common here than in the Sun Belt, because so much of Denver has a basement. Where we do find them is slab on grade ranches, additions built on slab, and some newer builds. The signs are a warm spot on the floor, the sound of running water underfoot, cracked tile with no impact, and a spike in the bill. Repair is either a reroute above the slab or a direct access repair, and the reroute is frequently less disruptive than it sounds.

A Supply Line Inside A Wall.

Pinhole corrosion in copper, a failed solder joint, or a split from a past freeze. These show up as a stain spreading on drywall or a ceiling below a bathroom. Freeze damage is its own category here and often stays hidden until spring, which is why a pipe that froze and did not obviously burst still needs watching.

A Drain Or Waste Line Leak.

Drains are not pressurized, so they leak only while something is draining. That intermittent pattern is the tell. A shower that stains the ceiling below only after someone bathes, or a kitchen line that drips only when the dishwasher empties. Camera inspection finds these directly, and our drain cleaning equipment is the same equipment that locates them.

A Silent Toilet Leak.

The most common leak in any house, and the one nobody notices, because the water runs straight down the drain. A worn flapper lets tank water escape continuously into the bowl. Put a few drops of food coloring in the tank, wait twenty minutes without flushing, and if color appears in the bowl the flapper is leaking. It is an inexpensive part and a fast fix. See toilet repair for what is involved.

Local Conditions

Three Things That Cause Leaks Along The Front Range

Denver homes fail in patterns, and the patterns come from the ground and the climate rather than from the plumbing.

Expansive clay soil swells when it takes on water and shrinks when it dries. That cycle works against anything buried or bearing on it, year after year, which is why buried service lines and slab plumbing fail here for reasons that have nothing to do with the age of the pipe.

Freeze and thaw is the second. A line that froze in January can split without flooding anything at the time, then leak quietly once the system is back under normal pressure. Our guide to keeping pipes from freezing in Denver covers the exposures that cause it.

High static water pressure is the third and the most overlooked. Pressure above eighty psi stresses every joint, fitting, and appliance connection in the house, and it is a code requirement to bring it down with a pressure reducing valve. We check static pressure on every leak call, because a house that keeps producing new leaks in different places usually has a pressure problem rather than a pipe problem.

Water Running Right Now?

Shut The Main Off First, Then Call

Active water inside a wall, a ceiling, or under a floor does damage every hour it continues. Close the main shutoff, move what you can out of the way, and call. Finding the source is the fast part once the water has stopped.

Questions

Frequently Asked Questions About Leak Detection In Denver

How do you find a leak without tearing up the house?

We start by isolating which part of the system is losing water, using pressure testing rather than guesswork. From there, acoustic listening equipment follows the sound of escaping water through pipe, soil, and concrete to its loudest point, and thermal imaging reads the temperature difference a leak creates behind a finished surface. Most leaks are pinpointed before anything is opened, and the opening we do make is sized to the repair.

How can I tell whether the leak is inside the house or in the buried line?

Shut off every fixture, then watch the water meter. If it is still moving, you have a leak. Next, close the main shutoff where the water enters the house and watch the meter again. If it keeps moving with the main closed, the leak is in the buried service line between the meter and the house. If it stops, the leak is somewhere inside. That one test saves a lot of time and it is the first thing we ask when you call.

Are slab leaks common in Denver?

Less common than in warmer parts of the country, because a large share of Denver homes have a basement rather than slab on grade construction. They do happen, mostly in slab on grade ranches, in additions built on a slab, and in some newer builds. The usual signs are a warm spot on the floor, the sound of water running underfoot, tile cracking with no impact, and a bill that jumped. Where we find one, rerouting the line above the slab is often less disruptive than opening the concrete.

My water bill jumped but I cannot see any water. What is the most likely cause?

A toilet flapper, by a wide margin. A worn flapper lets tank water run continuously into the bowl and straight down the drain, so nothing is ever visible and nothing is ever heard. Put a few drops of food coloring in the tank, leave it twenty minutes without flushing, and check whether color has reached the bowl. After that, irrigation lines and the buried water service are the next most likely, in that order.

Does homeowners insurance cover leak damage?

Policies commonly cover sudden and accidental water damage while excluding damage from a leak that was gradual or from deferred maintenance, but the terms vary and the decision belongs to your carrier rather than to us. What we can tell you is that documentation matters. We identify the source, describe what failed, and give you the findings in writing, which is the information an adjuster asks for. We are not insurance advisors and we do not file or negotiate claims.

Do you repair the leak, or only locate it?

Both. Some companies charge to locate a leak and then hand you a report to take to somebody else. We locate it and repair it under one licensed plumbing contractor, quoted as one written price you approve before work begins. Where a repair also touches electrical, we hold that license too, so it does not turn into a second contractor and a second trip.

Why does my house keep developing new leaks in different places?

That pattern usually points at something systemic rather than at each individual pipe. High static water pressure is the most common cause, and pressure above eighty psi stresses every joint and connection in the house until the weakest one fails, then the next. Aging galvanized supply and past freeze damage are the other two. We test static pressure on every leak call for exactly this reason, because fixing the sixth pinhole without fixing the pressure just schedules the seventh.

Do you pull permits for leak repair work?

Where the scope requires it, yes. A straightforward repair to an accessible line generally does not require a permit, while water service replacement, repiping, and work involving the meter or the main do. We tell you which category the job falls into before we start, we pull what is required through the City and County of Denver or the applicable suburban jurisdiction, and we meet the inspector.
