Frequently Asked Questions
How much does a kitchen remodel cost on Long Island?

Do I need a permit to remodel a kitchen or bathroom on Long Island?

Expect 2 to 4 months of active construction from demolition to final walkthrough, and roughly 3 to 6 months for the full project once design and selections are included.
