UNDERGROUND LEAK DETECTION SERVICES
RELIABLE UNDERGROUND & EXTERIOR LEAK DIAGNOSIS
UNDERGROUND LEAK DETECTION IN MYSTIC, CT
Water pooling in your yard for no clear reason, or moisture seeping through your foundation, usually points to something failing underground. At Superior Sewer & Drain Service, we help homeowners and businesses in Mystic and the surrounding area identify underground water and sewer leaks before they turn into serious structural damage.
We’re not a traditional indoor leak detection company- our focus is what’s happening below ground and around your foundation: failing underground water service lines, sewer laterals leaking beneath the surface, and water or sewage intrusion through a foundation. We confirm what we find using surface inspection, foundation assessment, and camera inspection of sewer and drain lines.
Don’t wait on a leak you can’t see- call us today for an accurate diagnosis.

FREQUENTLY ASKED QUESTIONS
We know you have questions about underground leak detection, and we’re here to help. Below are some of the most common questions we get from our customers:
What are the signs of an underground leak?
Common signs include water pooling or bubbling up in your yard with no clear cause, unusually soggy or lush patches of grass, water or sewage odor near your foundation, visible moisture where a foundation meets the ground, or an unexplained rise in your water bill.
Do you detect leaks inside the home, like behind walls or under sinks?
No. Our leak detection work is focused on underground and exterior issues- failing water service lines, sewer leaks beneath the ground, and water or sewage intrusion through a foundation. For issues inside your home’s plumbing, a general plumber may be a better fit.
How do I know if a leak is underground versus inside my house?
Underground leaks typically show up as water or soggy ground outside, moisture near your foundation, or sewage odor outdoors- rather than damp spots on interior walls or ceilings. If you’re not sure, we’re happy to take a look and point you in the right direction.
Will you need to dig up my yard to find the leak?
Not necessarily. We start with non-invasive methods- surface inspection, foundation assessment, and camera inspection of sewer/drain lines- to narrow down the source before any digging is needed.
What happens after you locate the leak?
Once we’ve confirmed the source, we’ll walk you through your repair options, which may include trenchless pipe lining, underground pipe rehabilitation, or traditional excavation depending on the extent of the damage.
Why do underground leaks matter if I can't see them?
Water escaping underground can erode soil around a foundation, undermine driveways and walkways, and- left long enough- lead to structural issues that are far more expensive to fix than the original leak. Catching it early makes a real difference.
