Bobby Contracts Inc. provides waterproofing in Brooklyn Heights for homeowners whose basements deal with seepage, dampness, or foundation cracks that have been quietly getting worse for years.

About Us

Why Basements Struggle in Brooklyn Heights' Oldest Homes

A large share of Brooklyn Heights sits within New York’s first designated historic district, and the buildings inside it were constructed long before waterproofing membranes, sump pumps, or modern drainage systems existed. Original stone and masonry foundations were never sealed the way foundations are today, which means moisture finds its way in slowly, through hairline cracks, porous masonry, or grading that’s shifted over a century of settling.

Basement waterproofing in Brooklyn Heights typically comes down to a few recurring problems:

Water seeping through original masonry or stone foundation walls
Chronic dampness or a musty smell that never fully clears
Cracks in foundation walls that widen gradually over time
White, chalky mineral buildup (efflorescence) on basement walls
Water intrusion after storms, even in basements that seem fine most of the year

Landmark Considerations for Foundation Work

Because much of Brooklyn Heights falls under landmark protection, exterior work on a home’s foundation or areaway sometimes involves additional considerations that wouldn’t apply in a non-landmarked neighborhood. We’re familiar with working around these constraints, which often means favoring interior waterproofing solutions when exterior excavation isn’t practical or appropriate for a landmarked property.

Waterproofing Systems We Install

The right system depends on your home’s foundation, layout, and whether exterior access is realistic given the property’s age and status. Options include:

Interior drainage systems — capturing water at its entry point and channeling it to a sump pump before it spreads
Sump pump installation — actively removing water that does make it into the basement
Exterior waterproofing membranes — sealing foundation walls from the outside, where yard or areaway access allows
French drains — rerouting groundwater away from the foundation before it becomes an interior problem

Signs Your Home Needs Waterproofing

Worth having your basement assessed if you’re noticing:

A musty smell that persists no matter how much you ventilate
Paint peeling or bubbling on basement walls
Cracks in foundation walls, particularly ones that seem to be growing
Water stains or damp patches that appear after rain
Mold or mildew forming along baseboards or in basement corners

In homes this old, these issues rarely resolve on their own — and tend to get more expensive to fix the longer they’re left unaddressed.

Frequently Asked Questions

Do you offer free estimates for basement waterproofing in Brooklyn Heights?

Yes. We inspect your basement and foundation, then provide a written, itemized estimate at no cost and no obligation.

Does my home being in a landmark district affect what waterproofing work I can do?

It can, particularly for exterior work. We’re familiar with these considerations and can recommend interior alternatives when exterior work isn’t practical or appropriate for your property.

Why do older Brooklyn Heights homes seem more prone to basement moisture?

Many were built with original stone or masonry foundations, constructed well before modern waterproofing methods existed, which makes them naturally more susceptible to gradual water intrusion over time.

Do you install sump pumps as part of waterproofing?

Yes, sump pump installation is often part of an interior drainage solution, especially for basements with recurring water issues.

How long does basement waterproofing typically take?

It depends on scope — interior systems are often completed in a few days, while exterior work may take longer depending on access and any landmark-related considerations. We’ll give you a realistic timeline during your estimate.
