When to worry about your foundation
Not every crack is a crisis. Thin, vertical hairline cracks are common as concrete cures. But some signs point to movement or water problems that get worse — and more expensive — over time:
- Horizontal cracks or bowing in basement walls
- Stair-step cracks in block or brick foundations
- Cracks wider than about a quarter inch, or that keep growing
- Doors and windows that start sticking
- Water seeping through walls or the floor joint
- Sloping floors above the basement
Not sure what you’re looking at? Our guide Are cracks in walls normal or dangerous? explains the difference.

Engineered when it matters
Structural foundation work in NYC typically needs a licensed engineer’s design and a DOB permit. For those projects we work with your engineer — or bring one in — and build exactly to the approved plans. For non-structural cracks and leaks, we can usually move straight to repair.
Typical cost
Our NYC price list shows foundation repairs commonly in the range of $5,000 – $20,000+ per job, including inspection. Small crack repairs cost less; underpinning and wall rebuilds cost more. We inspect for free and give you an itemized quote.

Are foundation cracks normal?
Small vertical hairline cracks are common. Horizontal cracks, stair-step cracks, wide or growing cracks, or cracks that leak should be inspected.
Do I need an engineer?
For structural repairs such as underpinning or major wall rebuilds, yes — and usually a DOB permit. For minor cracks and leaks, typically not.
Can you fix a leaking basement wall from inside?
Many leaks can be stopped from inside with crack injection and interior drainage. Some situations call for exterior excavation and waterproofing.
How long does foundation repair take?
Crack repairs often take a day. Wall rebuilds and underpinning can take one to several weeks, depending on engineering and permits.
