Brooklyn's Foundation Repair Specialists
Brooklyn was largely built between 1880 and 1930, and its foundations show it: rubble-stone and brick under Park Slope brownstones, unreinforced block under Bay Ridge two-family homes, shallow footings on variable fill — all of it 90 to 140 years into its service life. Add a high water table in Gowanus, Red Hook, and parts of Williamsburg, plus freeze-thaw hammering mortar joints every winter, and you get stair-step cracks, horizontal cracking from hydrostatic pressure, bowing walls, and flooded basements.
These are not cosmetic problems, but modern foundation repair is a solved problem. Epoxy and polyurethane crack injection, carbon fiber reinforcement, steel wall anchors, helical and push piers, and interior French drains give us a permanent fix for every foundation failure in NYC — details on our foundation crack repair and basement waterproofing pages for how each system works.
Every project with Brooklyn Foundation Pros starts with a free on-site assessment. We measure, photograph, and document what your foundation is doing — settlement, lateral movement, water entry points — and give you a straight answer about what it needs and what it costs. We serve Brooklyn, Queens, Manhattan, the Bronx, Staten Island, and Long Island.

Why Brooklyn Foundations Fail
Three forces do most of the damage: soil (clay under much of Brooklyn expands when wet and shrinks when dry, cycling foundations yearly), water (a high water table drives hydrostatic pressure against walls every heavy rain), and age (lime mortar softens over a century until unreinforced walls start bowing). Watch for stair-step cracks, horizontal cracking, bowing walls, sticking doors, and water after rain — if you see more than one, get an assessment. Our foundation repair FAQ answers the questions we hear most.
Frequently Asked Questions
How much does foundation repair cost in Brooklyn?
Crack injection typically runs $500–$1,500 per crack. Wall anchors run $800–$1,500 each. Underpinning with piers runs $1,500–$3,000+ per pier, with full jobs ranging $15,000–$40,000+. See our detailed NYC cost guide for full ranges.
Do I need a permit for foundation work in NYC?
Most structural foundation work — underpinning, wall rebuilds, significant excavation — requires NYC Department of Buildings permits. Crack injection and interior drain systems typically do not. We handle the permit process on jobs that need it.
Will foundation repair disrupt my home?
Interior work stays in the basement or crawl space. Exterior excavation is limited to the affected wall. Most families stay in the home throughout the project with minimal disruption.
