What We Do

The Full Scope of Our Fort Washington, MD Basement Waterproofing Work

Every Fort Washington, MD 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

Window wells that hold water after a storm are a direct pressure point against the glass and frame — we add gravel beds and drain lines tied into the main system.

How It Works

Our Four-Step Basement Waterproofing Dispatch Process

Call & Symptom Walkthrough

You describe what you're seeing — a wet spot, a musty smell, standing water — and we get a rough read on urgency before dispatching anyone.

02

On-Site Moisture Inspection

We also check exterior grading and downspouts, since a lot of basement leaks start outside, not inside.

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.

Frequently Asked Questions About Basement Waterproofing

How much does interior drain tile installation cost?

Every Fort Washington, MD quote is itemized in writing so you can see exactly what drives the total.
