What we cover

Observation, feasibility & coordination

As certified Pennsylvania Sewage Enforcement Officers, we perform percolation testing and soil evaluation ourselves and coordinate the licensed subcontractors for pumping and system work. One accountable partner, one calendar.

01

Perc tests & soil evaluation

Percolation testing and soil-probe evaluation performed in-house by our certified SEOs, the definitive answer to "can you build here?" for permit applications and land purchases.

02

Water & well sampling

Water samples collected for licensed-lab analysis, bacteria, nitrates, pH, and a feasibility read on existing wells.

03

Septic observation

Non-invasive visual observation of tank, distribution box, and drain field. Pumping and inspection coordinated through licensed pros.

04

Drain-line camera

Visual camera observation of existing drain lines, with recording. Any clearing or repair coordinated through licensed subcontractors.

05

Coordinated service

Filter, riser, and pump work coordinated end-to-end through licensed professionals. One contact, one schedule.

06

Site access & utilities

Access assessment, clearing coordination, and utility-locate scheduling so the right teams reach the right place.

07

Permit & vendor coordination

Power, road, and permit workflows. We hold the calendar and the paperwork so your team doesn't have to.

08

One accountable partner

A single project manager from first call to final report, scoped in writing, no surprise change orders.

09

Sewage enforcement (SEO)

Certified PA Sewage Enforcement Officers and PASEO members, providing on-lot septic feasibility, soil testing, and system-design support to guide your permit application.

Feasibility first

The soil decides the deal

Before a parcel is worth a builder's time, it has to perc. As certified Pennsylvania Sewage Enforcement Officers, we run the percolation test and soil evaluation ourselves, no waiting on a third party, so you learn what the land can carry before you commit.

Eyes on the system

See what's underground, without digging

Camera observation of existing drain lines, visual checks of tank and field, and water sampling tell homeowners and buyers the truth about a system's condition, non-invasively. When work is needed, we line up the licensed pros and manage the schedule.

How it works

Three steps to a number you can plan around

1

Tell us about the property

A short call: the parcel, the goal, the timeline. We'll say whether we're the right team, and if not, who is.

2

Scope & fixed price

A single written quote with everything coordinated under one project manager, not a vague estimate.

3

We run the plan

We do the observation, coordinate the licensed pros, hold the calendar, and report against the plan.

Where we work

Eastern Pennsylvania

Built around what we can drive to and stay accountable for, the corridor from Bucks through the Lehigh Valley. Inside the corridor, the answer is almost always yes. Outside it, ask, we'll be honest about whether we're the right partner.

Two minutes of detail. A real reply, usually same day.

Tell us a little about the property and we'll come back with the scope, timeline, and a fixed quote. If the work needs a credential we don't hold, we'll say so up front and point you to a trusted partner.

Prefer to talk to a person? Email us and we'll set up a call. Ten minutes and we'll tell you the truth about what the property needs.
