Questions to ask

What is your license or registration number, and under what business name?
Can I see your certificate of insurance, sent directly from the insurance company?
Who will do the work: your own crew or subcontractors?
Will you pull the permit, and who meets the inspector?
How do you handle changes and surprises once the walls are open?
What warranty do you give on the work, in writing?

Red flags

They knock on your door, or say the price is only good today.
They ask for most of the money before work starts, or only take cash.
They suggest skipping the permit to save time or money.
The name on the contract does not match the license lookup.
There is no written contract, or the contract is vague about the work and the price.

Westchester County rules

Westchester County licenses home improvement contractors through its Department of Consumer Protection. Search the county's licensed contractor lookup before you sign.
Contractors who work in Yonkers must also be licensed by the city's Consumer Protection Bureau.
County license holders go through a background check and must show proof of insurance.
Ask your city, town or village building department which permits your job needs.

How old are the homes in White Plains?

The Census counts about 27,561 homes in White Plains. About 30 percent were built before 1940, 71 percent before 1980, and 17 percent in 2000 or later.

What that means here

Homes built before 1978 may have lead paint, so painting, window and demolition work needs an EPA certified firm.
Older homes often hide surprises once walls are opened, like old wiring or plumbing. Ask how the contract handles them.
Newer homes may still be under a builder warranty. Check it before you hire someone else.
