Septic Systems
We design and install new septic systems for homes and small businesses, from initial excavation through backfill and final grading. Every system is sited and installed to fit the property and meet New Hampshire state requirements, which means the process starts well before any digging: soil testing, layout, and a design that matches the lot rather than a stock plan pulled off the shelf.
Once the design is approved, we excavate for the tank and leach field, working carefully around existing trees, ledge, and site features that the design needs to account for. Getting the depth, slope, and separation distances right at this stage is what makes the difference between a system that works quietly for decades and one that causes problems down the road.
We’re certified installers of both GeoMat Leaching Systems and Geomatrix Systems, so we can recommend and install the leach field technology that best fits your soil conditions and lot size rather than a one-size-fits-all approach. Tighter lots or challenging soil often call for these engineered systems instead of a conventional stone-and-pipe leach field, and we install both to state specification.
Setting the tank, running the lines, and connecting the distribution box all have to happen in the right order and at the right elevations for the system to function correctly. We take the time to get every connection and grade right before anything gets backfilled, since a septic system is one of those projects where the parts you can’t see afterward matter the most.
We also handle foundation coring, drilling clean, precise openings through existing foundation walls to tie a septic line into a home without a full foundation dig. That makes us a good fit for retrofits and replacement systems on existing houses, not just new construction, where opening up a whole section of foundation just to run a pipe would be overkill.
Once the tank, lines, and leach field are in and inspected, we backfill and final-grade the site so the yard is left usable and graded to shed water away from the system rather than toward it. That final grading step matters as much as the installation itself for the long-term health of the system.
Whether you’re building new or replacing a failed system, we’ll walk you through the process and keep you informed from the first dig to the final inspection.
