What we do

Two trades, one crew, one phone call.

Most septic jobs turn into excavation jobs. We do both in-house, so nothing waits on a second contractor showing up.

Septic 01
  • New septic installs

    System design, sizing, permitting and installation for new builds and full replacements.

  • Drain field repair & replacement

    Diagnosis, partial repairs, and complete leaching bed rebuilds when a bed is finished.

  • Perc tests & soil evaluations

    Percolation testing and soil profiles for permits, land sales and new construction.

  • Real estate inspections

    Point-of-sale inspections with a written report your closing attorney can use.

  • Risers, lids & pump repairs

    Effluent pumps, alarm calls, baffles, and access risers brought up to grade.

Excavation 02
  • Site prep & grading

    Clearing, cut and fill, pad building and finish grade for new construction.

  • Land clearing

    Brush, stumps and tree removal with haul-off or on-site burial where permitted.

  • Utility trenching

    Water, sewer, electric and gas runs dug to spec depth and bedded properly.

  • Driveways & culverts

    New gravel drives, regrading, ditching, and culvert pipe set to drain right.

  • Foundation & basement digs

    Footings, foundations, crawl spaces and backfill on a builder's schedule.

  • Demolition & haul-off

    Outbuildings, slabs, old tanks and debris removed and disposed of legally.

How a job runs

You'll know what's happening at every stage.

A septic install takes most crews two to four weeks start to finish, and the township sets part of that pace. Here's the order it goes in.

STEP 01

Site visit

We walk the property, locate the existing system or stake the new work, and price it. No charge.

STEP 02

Test & design

Perc test and soil evaluation where required, then a system sized to the house and the ground.

STEP 03

Permits

We file with the township office and schedule the inspections on your behalf.

STEP 04

Install

Tank set, lines run, field built — then inspected and signed off before anything gets covered.

STEP 05

Restore

Backfill, final grade, seed and straw. Ruts filled, debris gone, gate closed behind us.
