Basement Remodeling in Irvington, NY

Irvington is a Hudson River village with steep streets: the typical home was built around 1956 and 69% pre-date 1980. Westchester County requires home improvement contractors to hold a county license, and the county does not show license numbers in its public search, so we list the license expiry we found in the county's online search and note when a number comes from the company's own site. Plumbing and electrical work in a remodel may need separately licensed trades. Your town or village building department sets permit and inspection rules, so ask which permits apply before work starts.

How we pick: we list up to six companies per page. Independent firms come first, then firms based outside Westchester, then franchise or network affiliates.

What it costs

A modeled estimate for White Plains puts basement finishing at $26 to $84 per square foot, with a planning midpoint near $52 (RenoVetted). For an 800 square foot basement that works out to about $41,872, with comparable bids roughly $20,936 to $66,995. Nationally, HomeGuide cites $30 to $50 per square foot, or $15,000 to $75,000 for 500 to 1,500 square feet. These are modeled and national figures, not Westchester bid data, and we did not find any Westchester contractor price lists. Full cost guide with sources.
