Why Choose Us

What Sets Our Basement Waterproofing Team Apart in Somerville, NJ

Basement waterproofing mistakes usually come down to one thing: fixing the symptom instead of the source. A contractor who paints over a wet wall without checking cove joint condition or exterior grading is setting you up for the same call again in a year or two.

What We Do

What Our Basement Waterproofing Service Actually Covers

Every Somerville, NJ Basement Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.

Basement

Interior Drain Tile

We route drain tile beneath the existing slab line so flooring disruption stays minimal during installation.

Basement

Sump Pump & Basin Installation

Every drain tile system needs a properly sized sump pump — we calculate basin size and pump horsepower from your square footage and local water table depth.

Basement

Wall Crack & Cove Joint Sealing

Vertical wall cracks get epoxy or polyurethane injection depending on whether they're still actively weeping.

Basement

Vapor Barrier Wall Membrane

We install membrane on masonry walls before any insulation or framing goes up, so moisture never gets a chance to reach finished materials.

Basement

Window Well Drainage

Poor window well drainage is one of the most overlooked Somerville, NJ basement leak sources, and it's often the cheapest fix on the list.

How It Works

Our Four-Step Basement Waterproofing Dispatch Process

01

Call & Symptom Walkthrough

A quick phone conversation lets us bring the right equipment on the first visit instead of a second trip.

03

Written, Itemized Quote

We explain the reasoning behind the recommended system so you know exactly what you're paying for and why.

04

Installation & Warranty Walkthrough

Most residential basement jobs finish in one to three days, and we test the sump pump under load before we leave.
