01

Site Evaluation

Day 1

We walk the property, locate the existing system, measure required setbacks from property lines, wells, and structures, and assess soil conditions and slope. For a new install, you leave with a written scope, a budget band, and a rough timeline. No obligation.

02

Permit & Planning

Weeks 1–3

We file the permit application with the Onondaga County Health Department. Where soil tests or perc tests are required, we coordinate those directly. We handle the paperwork, the scheduling, and the back-and-forth with the county so you don't have to.

03

Excavation & Install

Install day(s)

Our licensed crew arrives with the right equipment. Every measurement, depth, and separation distance is logged as we go. Tanks are set, distribution components are installed, and the drain field is placed to spec. Nothing gets buried until it's correct and photo-documented.

04

County Inspection

Within 1 week

We schedule the Onondaga County Health Department inspector and walk them through the completed work. Sign-off is the milestone. We don't backfill until the inspector has seen what needs to be seen and the permit is approved. No exceptions.

05

Backfill & Restore

Closeout

Grade is restored to match the original contours. Disturbed areas are seeded. Equipment tracks are cleaned up. We hand you a copy of the approved permit, the as-built drawing, and any component warranties. The yard should look better than it did when we arrived.

The short version

Three things that don't change.

Regardless of the job size or complexity, these three things hold on every C Mattes project.

01

Nothing Buried Without Sign-Off

The Onondaga County inspector approves the work before we backfill. That's not negotiable. It protects you legally, it protects you when you sell, and it's the only way to know the system was installed correctly.

02

The Invoice Matches the Quote

If something changes during the job that affects cost, you hear about it in writing before the change is made. The number on the final invoice matches what was agreed on — or there's a written change order explaining the difference.

03

Documentation You Can Use

Permit copy, as-built drawing, component warranties — every project closes with a document package. When you sell the house or call for future service, you have what you need on file.
