How your utility job runs
The difference between a clean utility job and an expensive one is what happens before the machine ever swings. Here's our process on every run.
Site walk & layout
We map every run, depth, and tie-in point before a machine moves — and price it line by line.
811 markout & potholing
Every job. We locate and hand-verify existing lines so nothing gets struck.
Trench to code depth
Below CT's 42-inch frost line — water service sits ~5 ft so it never freezes.
Pipe, bedding & tracer wire
Proper bedding, warning tape, and tracer wire so the next contractor can find your line.
Tie-in & test
Connected to town main or structure, pressure/leak tested, and passed by inspection.
Backfill & restore
Compacted in lifts so nothing settles, then lawn or pavement put back the way it was.
Why homeowners, builders, and towns call us
811 on every single job
No exceptions. We pothole to verify depth before digging near live lines.
One coordinated trench
Water, sewer, and conduit go in together — one mobilization, not five separate charges.
Below the frost line
Dug and bedded to CT code so lines never freeze, heave, or fail inspection.
Tested tie-ins
Pressure and leak tested, tracer wire installed, built to each town's standard.
Licensed & insured
CT Lic. #NHC.0014110 — municipal-grade work backed by real coverage.
24/7 break response
Water main break or collapsed trench? We mobilize day or night.
Whatever you're building, we've dug it
Three kinds of clients, one standard of work.
Homeowners
Failed line, freezing service, or switching your well to city water?
We locate the problem, replace the run, tie back in, and restore your yard — usually in a day or two, quoted up front with no surprises.
Builders & GCs
Need every utility in the ground before the foundation crew shows up?
We open and close one coordinated trench on your schedule, work to the engineer's plan, and hit your grade tolerances so nothing burns your margin.
Commercial & Municipal
Deeper mains, full storm networks, connections to town infrastructure?
We've tied into municipal water and sewer across Eastern CT and build to each town's standard for materials, thrust blocks, and testing.
Local knowledge
Underground utility work in Windham & New London counties
Underground utilities are the backbone of every site — and the part most likely to blow a schedule when it's done wrong. We install and replace water service and water main, sewer and septic laterals, storm drainage with catch basins and manholes, and electric, gas, and telecom conduit. On a typical residential run that means water service at 5 feet deep (below CT's 42-inch frost line), a sewer or septic lateral pitched to grade, and conduit for power and communications — often all in one coordinated trench so the property is opened and closed once, not five times.
The difference between a clean utility job and an expensive one is planning around what's already in the ground. We call 811 for markouts on every job, hand-dig in congested zones, and pothole to verify depths before the excavator ever swings. Bedding, warning tape, tracer wire, and compacted backfill to code aren't optional — they're what keeps the tie-in from failing inspection and what protects the next contractor from your line. We coordinate connection dates with the water company, the sewer authority, and Eversource so the trench opens when the utility is ready to connect, not weeks before.
For commercial and municipal work we handle deeper mains, larger storm systems, hydrodynamic separators, and connections to existing town infrastructure. We've tied into municipal water and sewer across Eastern CT and know each town's standards for materials, thrust blocks, and testing. Whether it's a single house service or a full site's storm and sanitary network, we quote it line-by-line so you can see exactly what the trench, the pipe, the structures, and the connection each cost.
