Slab Leak Detection & Repair in Norwood, MA

Common Signs of a Slab Leak

Fixture Installation & Repairs

Slab leaks don’t always announce themselves with obvious flooding. In many cases, the warning signs are subtle at first and easy to overlook.

If you’re experiencing any of these issues, it’s important to have your plumbing system inspected before the leak causes further damage beneath the slab.

Warm or hot spots on floors
Unexplained spikes in water bills
The sound of running water when no fixtures are on
Low or inconsistent water pressure
Damp carpet, warped flooring, or loose tiles
Mold or mildew smells with no visible source
Cracks forming in flooring or along the foundation
Water pooling around the perimeter of the home

How Slab Leak Detection Works

Accurate detection is the most important part of slab leak repair. At Dalelis, we focus on locating the exact source of the leak before any repair work begins. This approach minimizes disruption and prevents unnecessary damage to your home.

Our slab leak detection process may include:

Electronic leak detection to identify pressure changes
Acoustic listening equipment to detect water movement beneath the slab
Pressure testing to isolate failing lines
Thermal imaging when temperature differences indicate hidden leaks
Video camera inspection when accessible piping allows

By pinpointing the leak precisely, we can recommend the most effective repair option without tearing up floors or concrete unnecessarily. Our goal is to solve the problem accurately the first time while protecting your home.

Excellent service. Responded quickly to confirm my appointment and the work was completed quickly the same day. We will be using this company for our yearly heating maintenance.

I had a great experience working with James and his team to install our new boiler and water heater. He worked to understand our needs, gave us solid advice, and provided a competitive bid with no extras or upsells (and no BS!).  His work was very professionally done, and it was obvious that he took great pride in his work and in providing the most useful components. He also took the time to explain the work, how the equipment worked, and made sure the settings were what we we were looking for.  All in all a great experience, and we will be working with him again.

Frequently Asked Questions

How do I know if I need slab leak detection?

If you're experiencing any of these warning signs, it's time to call for professional slab leak detection:

Unexplained high water bills - Your usage hasn't changed, but costs keep climbing every month.

Sound of running water when everything's off - You hear water flowing through pipes even when no fixtures are in use.

Warm or cold spots on your floors - Hot water line leaks create warm areas, while cold water leaks leave cool zones on your foundation.

Cracks in walls, floors, or foundation - Water eroding soil beneath your slab causes shifting and cracking.

Low water pressure throughout your home - Leaking lines lose pressure before water reaches your faucets and fixtures.

Mold, mildew, or musty odors - Moisture trapped under your slab creates the perfect environment for mold growth.

Damp carpet or flooring - Water seeping up through your foundation, even in areas far from plumbing fixtures.

Your water meter runs constantly - Turn off all water in your home and check your meter, if it's still moving, you've got a leak somewhere.

 How long does it take to detect a slab leak?

Most slab leak detection appointments take 1-3 hours depending on your home's size and plumbing layout. Our team uses specialized equipment including acoustic listening devices and electromagnetic pipeline locators to identify the exact location of the leak quickly and accurately. Once we've pinpointed the problem, we'll explain your repair options and provide a clear timeline for fixing it. The faster we detect it, the faster we can stop the damage.

Can a slab leak be fixed without breaking the concrete?

In some cases, yes. If the leak is accessible through existing access points or if epoxy pipe coating is a viable solution, we can seal the leak without demolishing your foundation. However, many slab leaks require targeted concrete removal to access and repair the damaged pipe. The good news? Our precision detection means we only remove the concrete necessary to fix the problem, not your entire floor. For homes with multiple leaks or aging pipes, we may recommend rerouting new lines through walls or attic spaces, completely avoiding the slab and preventing future issues.
