How It Works — From Violation to Compliance
Our SoHo Process – Invisible and Board-Ready
Most foundation repair and replacement SoHo projects finish in 5–14 days while residents stay comfortably in place.
The Problems We Solve Daily in SoHo
- Sudden 3–10 inch drops when the last timber pile finally collapses
- Sloping loft floors that send furniture sliding toward Greene Street
- Water infiltration in lower-level galleries and storage spaces
- Cracks propagating from original cast-iron columns
- Bowed brick party walls from decades of lateral soil pressure
- Collapsing sidewalk vaults under heavy pedestrian traffic
- Emergency red tags after façade inspections
We’ve corrected every one of these on Wooster, Greene, Mercer, Crosby, and every cobblestone side street.
SoHo is home to some of the most valuable real estate in the world: 1860s–1880s cast-iron warehouses reborn as multi-million-dollar lofts, converted manufacturing buildings with 14-foot ceilings, and the occasional surviving Federal-style townhouse tucked on a side street. Beneath the exposed brick and timber beams, most sit on shallow rubble foundations or rotted timber piles that have spent 140 years submerged in groundwater. Add constant subway vibration from the 6, N/R/W, A/C/E, and construction everywhere, and settlement is inevitable: sloping loft floors, cracked cast-iron columns, leaking basement galleries, bowing party walls, and DOB violations that can kill a closing overnight.
Protect Your SoHo Investment Before the Next Façade Cycle
One failing pile can trigger a seven-figure assessment. A discreet inspection today prevents it.
