Why Guessing Costs More

Opening a wall to look for a leak can turn a small repair into a large one. We use acoustic, thermal and moisture tools to narrow down the location before anyone cuts anything.

In the older homes of the historic core, supply lines may be dated, so a leak can be one of several weak points rather than a single failure. In newer subdivisions, a leak is more often at a fitting, a fixture connection, or the service line. We test for the actual cause.

A running toilet, a dripping valve under a sink and a pinhole in a supply line all look different on a water bill. We start with the simple checks, such as the meter test and the fixtures, before moving to the tools.

Signs worth checking

  • →A bill higher than usual with no change in use
  • →A meter that moves with every fixture off
  • →A damp or warm spot in a floor
  • →Low pressure that arrived gradually
Meter and Main

Know Whose Pipe It Is

Your water meter is the dividing line. In most of Black Diamond the City owns the water system up to that point; the Lake Sawyer area is served by Covington Water District instead.

Before we dig anywhere, we confirm which side of the meter the leak is on. If it is on the utility's side, we tell you who to call. If it is on yours, we quote the repair.

After We Locate It

Repair, Then Restoration by Others

Finding the leak is the diagnosis. We then quote the plumbing repair. If walls or floors need to be opened for access, finish restoration is handled by others unless it is listed in writing.

Lake Sawyer properties include older lakeside homes and newer construction nearby, so we check the age and layout of the plumbing before suggesting the next step. Leak detection reduces demolition, but it cannot promise none.

Once we confirm the source, we can also check whether other fittings on the same run are at risk, so you are not paying for the same trip twice. Estimates are free, and the price is flat rate and in writing.

FAQs

Common Questions: Leak Detection in Black Diamond

How do I tell if the leak is on the City side of the meter?

Close your main shutoff at the house. If the meter still moves, the leak is likely before the house. Call the utility. If it stops, the leak is on your side.

Can you find a slab leak without demolition?

We use acoustic and thermal tools to pinpoint the likely spot first. Some repairs still require access to confirm and fix the pipe.

Do you repair the walls too?

No. We repair the plumbing. Wall, floor and finish restoration is handled by others unless included in writing.
