Underground plumbing
Underground plumbing is the part of the system you never see but rely on every day. We install and repair the buried lines that carry water into a building and waste away from it.
This is careful, methodical work. We test before we cover anything up and restore the site when the job is done.

Underground, under-slab, sewer, and water-service: what is the difference?
These terms overlap, so here is how they relate.
- Underground plumbing is the broad category: any pipe buried in the ground around or beneath a building.
- Under-slab plumbing is the portion of underground plumbing that runs directly beneath a concrete slab foundation.
- Sewer-line work deals with the drain and waste lines that carry wastewater away to the main or septic system.
- Water-service work covers the pressurized line that brings fresh water from the main into the building.
Frequently asked questions
How do you find a leak in a buried pipe?
We use the signs available, such as wet spots, pressure loss, and unexplained water use, along with detection methods to narrow the location before we dig, so we excavate only where needed.
Do you handle the digging or do I need someone else?
We handle trenching and coordinate excavation as part of the job, including utility coordination, and we backfill and restore the site once the line passes testing.
What is under-slab plumbing?
It is the plumbing that runs beneath your concrete slab foundation. Repairs there take extra planning since the pipes sit under the floor, and we work to keep access as clean and contained as possible.

Sewer line services
Your sewer line carries everything away from the building, so when it fails you notice fast. We diagnose sewer trouble and handle everything from cleaning a clogged line to replacing a collapsed one.

The water line is the pressurized pipe that brings fresh water into your building. When it leaks, corrodes, or breaks, you feel it in your pressure, your water bill, or a soggy patch in the yard.
Learn moreLeak detection services
Some leaks announce themselves, and some hide behind walls or under the slab until the damage is done. We track down the source of a leak so the right pipe gets fixed instead of a wall getting opened on a guess.
