Your building envelope, including walls, foundation, windows, roof edges and flashing, is what keeps water out. When any part fails, leaks follow. Homex Builders provides complete exterior waterproofing for homes and buildings across the Bronx, Manhattan, Brooklyn, Queens, Staten Island, Yonkers, Long Island and New Jersey.

We inspect the full exterior to find vulnerable areas, then combine masonry and stucco repair, sealants, flashing, coatings and drainage improvements into one plan that keeps the whole building dry.

What Our Exterior Waterproofing Includes

A complete exterior waterproofing project may include:

Envelope Inspection

Checking walls, windows, flashing, parapets and grade for water entry points.

Sealing & Coatings

Caulking, sealants and breathable coatings for masonry and stucco.

Flashing & Drainage

New or repaired flashing, gutters and grading that direct water away.

Treating the exterior as one system, not one leak at a time, is the most effective way to keep water out of your building for good.

Frequently Asked Questions

What does exterior waterproofing cover?

It can include walls, foundations, windows and doors, parapets, flashing, balconies and drainage around the building.

How do I know where my building is leaking?

We inspect inside and out, trace stains back to entry points, and check common failure areas such as windows, flashing and mortar joints.

Is exterior waterproofing worth it?

Yes. Stopping water at the exterior prevents interior damage, mold and costly structural repairs.

How much does exterior waterproofing cost in NYC?

Pricing depends on the size of the area, the condition of existing materials, access and the materials you choose. We provide a free on-site estimate with a clear scope and price before any work begins.

Do I need a permit for this work?

Exterior work on larger buildings may require DOB permits, scaffolding and sidewalk protection. We help coordinate requirements.
