About Roadway Excavators

Roadway Excavators is a Derry, New Hampshire company that combines septic services with full excavation capabilities, which makes them a strong option when a job requires more than just a pump truck. Derry's older residential stock and ongoing new construction activity create demand for both system repairs and new installations. They carry a perfect 5.0 rating, though it's based on one review so far. For projects that involve digging, grading, or full system replacement, having excavation and septic under one contractor simplifies the whole job.

Services & Process

Roadway Excavators handles septic work that goes beyond routine maintenance. On the excavation side, they can dig for new septic system installations, expose existing tanks and drain fields for repair or replacement, and grade sites to ensure proper drainage. Their septic services include tank pumping, system inspections, and drain field assessment. When a failing drain field needs to be replaced or a homeowner is building on a new lot in the Derry area, this kind of combined capability means you're not coordinating between two separate contractors.

Frequently Asked Questions

What's the difference between a septic repair and a full system replacement?
A repair typically addresses a specific component, like a damaged baffle, a cracked pipe, or a localized section of drain field that has failed. A full replacement involves removing and reinstalling the tank, distribution box, and drain field, which is a much larger excavation project but is sometimes the most cost-effective long-term solution.
Do I need a permit to install or replace a septic system in Derry, NH?
Yes, New Hampshire requires permits for new septic installations and most major repairs, issued through the NH Department of Environmental Services. Your contractor typically handles the permit application, but it's worth confirming this upfront so there are no delays once work is scheduled.
How long does a new septic system installation take?
A straightforward installation on a clear lot can often be completed in two to three days once permits are in hand. More complex sites with ledge, poor soils, or tight access may take longer, and permit processing time can add several weeks to the overall timeline.
What soil conditions affect how a septic system is designed in New Hampshire?
Soil permeability, depth to groundwater, and proximity to ledge all factor into system design under NH regulations. Sandy soils drain quickly and may require different design approaches than clay-heavy soils, which is why a site-specific evaluation is required before installation.
Can excavation damage my existing septic system or drain field?
It can, if the contractor isn't aware of where components are located before digging begins. That's why it's important to work with a contractor who reviews as-built plans and probes the site before operating heavy equipment near your existing system.
How do I know if my drain field has failed and needs replacement?
Standing water or soggy ground above the drain field, sewage odors outdoors, and toilets or drains backing up after the tank has been pumped are common signs. A formal inspection, which may include dye testing or camera inspection of distribution lines, can confirm whether repair or replacement is needed.
