How to choose a foundation repair company in New York
A crack in a basement wall or water on the floor after a storm is stressful, and the first company you call may not be the right one. Some companies listed here mostly keep water out. Others mostly fix walls and foundations that have moved. Many do both. This guide covers what to look for before you sign anything.
Know which problem you have
Water coming in is usually a waterproofing job: drain tile, a sump pump, sealing cracks or encapsulating a crawl space. Walls that bow, floors that sag or doors that stick point to a structural problem that calls for wall anchors, braces or piers. A good company will tell you which one you have after an inspection, and many listed here say they offer that inspection for free. Weather matters here: New York averages a little over 40 inches of precipitation a year, total precipitation has been well above average since 2000, and 2-inch downpours have become much more common.
Check the contractor's license
New York State does not license home improvement contractors, but some counties and cities do. New York City requires a Home Improvement Contractor license from the Department of Consumer and Worker Protection; look one up with DCWP's business search. Nassau County (license search), Suffolk County (license search) and Westchester County (licensed contractor search) license contractors too, and Putnam County runs a mandatory registration program. Elsewhere, ask your city or town. The listings on this site show whether a company states a license on its own website. This site does not check licenses.
Get it in writing
Under New York's General Business Law, a home improvement contract must be in writing and signed by everyone, and you must get a signed copy before any work starts. You may cancel until midnight of the third business day after signing. The contract must also explain how the contractor handles payments received before the job is finished.
Ask about permits and digging
Each city, town and village enforces the state building code itself, so permit rules are local. In New York City, most construction needs a Department of Buildings permit, and underpinning work must be shown on approved drawings. Syracuse lists foundation and site work among projects that need a permit. Ask the company who pulls the permit. If the job means digging outside, state rules require the excavator to notify 811 at least two working days, and no more than ten, before digging starts.
How to read a listing
Each listing shows the services a company names on its own website. A service under "No information yet" means the company's site does not say. Call and ask.
