Why Choose Us

Four Reasons Our Basement Waterproofing Clients Don't Call Anyone Else

What We Do

Comprehensive Basement Waterproofing Solutions in Somerset, NJ

Every Somerset, 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

A dimpled plastic membrane behind any finished basement wall channels residual moisture down to the drain tile instead of trapping it behind drywall.

Basement

Window Well Drainage

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

FAQ

Basement Waterproofing Questions We Hear Every Week

How much does interior drain tile installation cost?

Cost depends on linear footage, sump basin size, and whether cove joint sealing is included — we won't give a number without an in-person inspection.

Will you cut into my basement floor?

Yes — interior drain tile requires cutting a channel along the slab edge, which we patch with concrete once the system is installed.

How long does basement waterproofing take?

Most residential interior drain tile and sump installations finish in one to three days depending on basement size.

Do I need a sump pump if I'm just sealing a crack?

If the crack is actively weeping or part of a larger drainage issue, we'll recommend a full system instead of a spot fix.

Is basement waterproofing covered by insurance?

We provide photos and moisture readings that many Somerset, NJ homeowners have used to support a claim.

Do you offer a warranty on basement waterproofing work?

Yes, every interior drain tile and sump installation comes with a written warranty, explained in full before you approve the quote.
