What We Do

Comprehensive Basement Waterproofing Solutions in Dover, NJ

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

Basement

Interior Drain Tile

The core fix for most Dover, NJ basements: a perimeter drain cut into the slab edge, tied to a sump basin, that intercepts water before it reaches the floor.

Basement

Sump Pump & Basin Installation

Battery backup is available for any sump system, so a power outage during a storm doesn't undo the whole fix.

Basement

Wall Crack & Cove Joint Sealing

The cove joint where the floor meets the foundation wall is one of the most common Dover, NJ leak points, and we seal it as part of every interior system.

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.
