About Bandow Co., Inc

A local New York waterproofing company focused on practical solutions and long-term results.

Upper Manhattan brownstone buildings

A Local Waterproofing Company

Bandow Co., Inc is a waterproofing company based at 210 E 117th St in Upper Manhattan, New York. We work with homeowners, building managers, and small businesses across NYC who need someone reliable to look at a water issue, explain it clearly, and fix it properly.

Our focus is narrow on purpose. Waterproofing — keeping water out of basements, walls, and structures — is its own specialty. By staying focused on this work, we can give each project the attention it deserves and recommend the approach that genuinely solves the problem.

How We Work

A straightforward, transparent process from the first call to the finished job.

1. Inspect

We come to the property, look at the affected areas, and ask questions about when and how the water issue appears.

2. Diagnose

We trace water issues back to their actual source — not just the visible symptom — so the repair addresses the real problem.

3. Estimate

You get a written estimate with the scope, materials, and timeline. Questions are welcome before any work begins.

4. Complete

Our team carries out the work carefully, keeps the site tidy, and walks you through the finished results.

Rooted in Upper Manhattan

Operating from East 117th Street places us right in the middle of the kinds of buildings we know best — brownstones, prewar apartment buildings, mixed-use storefronts, and townhouses across Upper Manhattan, Harlem, Washington Heights, and Inwood. We also work on properties throughout the rest of Manhattan, the Bronx, Brooklyn, and Queens.

NYC buildings are not all the same. A leaky basement in a 1920s walk-up needs a different approach than a damp masonry wall on a renovated commercial space. Our experience with the local building stock helps us recommend solutions that actually fit the property in front of us.

What We Value

A short list of the things that guide how we do the work.

Honest Diagnosis

If a smaller repair will solve the issue, we say so. We won't recommend more work than the property needs.

Quality Materials

We choose materials that suit the conditions — interior versus exterior, freeze-thaw exposure, type of substrate.

Clear Communication

We explain what we found, what we recommend, and why — in plain language, without jargon.

Respect for the Property

We work cleanly and efficiently, mindful that people live and work in the buildings we're called to.
