What We Do

The Full Scope of Our Plainview, NY Basement Waterproofing Work

Every Plainview, NY 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 Plainview, NY 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

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.

FAQ

What Plainview, NY Customers Ask Us Most About Basement Waterproofing

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?

Not always — an isolated, non-leaking crack can sometimes be handled with injection alone.

Is basement waterproofing covered by insurance?

Coverage depends on your policy and the cause of the water intrusion — we can document conditions for a claim, but approval is up to your insurer.

Do you offer a warranty on basement waterproofing work?

Warranty terms are often transferable if you sell the property later.
