How It Works — From Violation to Compliance
Our Historic-District-Friendly Process
Most foundation repair and replacement Park Slope projects finish in 5–15 days while families and tenants stay comfortably in place.
The Foundation Issues We Fix on Nearly Every Block in Park Slope
- Parlor floors sloping toward the garden (classic sign of rear settlement)
- Front stoops pulling away from the brownstone façade
- Bowed or bulging basement walls from clay soil pressure
- Diagonal and stair-step cracks above windows and doors
- Chronic water in the basement after every storm
- Separating party walls between attached row houses
- Tree-root damage from the neighborhood’s mature London planes and oaks
We’ve corrected every one of these on Prospect Park West, 8th Avenue, Carroll Street, Montgomery Place, and the numbered streets from 1st to 15th.
Park Slope is Brooklyn’s architectural crown jewel: block after block of late-19th and early-20th-century brownstones, Renaissance Revival limestones, and stately six-story co-ops, many designated as part of the Park Slope Historic District. Beneath the original parquet floors and plaster medallions, however, most of these buildings rest on shallow brick-and-stone footings that were never meant to handle modern loads, expansive clay soil, or 100+ years of groundwater movement. The result is the same story we hear every week: sloping parlor floors, sticking pocket doors, cracked stoops, bowed basement walls, and DOB violations that can quickly turn into six-figure special assessments.
