Getting started
What does an underground utility contractor do?
We install, repair and replace the buried lines that serve a property: water, sewer, storm drains, electrical and communications conduit, and the trenches for gas lines. We also handle the excavation, boring, backfill and restoration around them.
Do you work in my city?
We serve Nashville and 35 more cities and towns across Middle Tennessee. Each has its own page on this site, and if yours is not listed, call and ask.
Can you take on both small and large jobs?
Yes. A single service line for a home and a multi-phase site utility package use the same careful approach, with equipment and crews sized to the work.
How do I get a quote?
Send the form on this page or call (615) 393-6985. We usually start with a conversation and a site visit, then explain the scope and the price before work begins.
Locates and safety
Who calls 811?
Anyone planning to dig should call 811, whether it is a homeowner, a builder or a contractor. We coordinate locates on every job we dig and confirm marks are in place before excavation starts.
Does 811 mark private lines?
No. Utilities mark their own lines. Private lines beyond the meter, such as a water line to a barn or a buried electric feed, are the owner’s responsibility, and we can help locate them.
How deep is too deep to dig without protection?
General excavation rules call for protective systems in trenches 5 feet deep or more, with egress needed from 4 feet. Our trench safety tool explains the rules in plain language, and we plan protection on every deeper dig.
What if a line is hit?
Stop, move away and call 911 for gas, fire or electrical danger, then call the utility owner. Do not try to repair or cover a damaged line.
Methods and materials
When is boring better than trenching?
When the route crosses something costly to cut: a road, driveway, patio, creek or mature trees. Open trenching is often simpler over open ground and for gravity pipe that needs exact grade.
What do you do about rock?
Rock is common in Middle Tennessee. We probe early, then hammer, rip or reroute depending on the amount and where it sits.
What pipe do you use?
Whatever the utility, engineer or code specifies, such as polyethylene for water and conduit, PVC for sewer and storm, and ductile iron for large pressure lines and fire service.
Will you restore my yard and driveway?
Yes. Backfill, compaction, sod or seed, concrete and asphalt patches are part of the plan and the price we discuss with you.
Cost and timing
How much does a utility line cost to install?
It depends on length, depth, pipe size, rock, access, boring versus trenching and what the route crosses. Our cost planner shows factors with placeholder ranges, and we quote your job after a site visit.
How long does a job take?
A single home service can take days, while larger projects take longer. Permits, utility connections and inspections often control the finish date more than the digging does.
Do I need a permit?
Often. Taps, right-of-way work, septic systems, grading and building work all have their own permits, and we help you find out what applies at your address.
Is the lowest bid the best deal?
Not always. Compare scopes: locates, rock allowances, compaction, hauling and restoration. A bid that leaves them out is not really lower.
