Get at least three written estimates for the same scope of work, so you compare like with like.
Look up each contractor on the official license lookup linked on this page.
Ask for proof of liability insurance and, if they have workers, workers compensation.
Read the contract before you sign. It should list the work, materials, price, payment schedule and start and finish dates.
Confirm who pulls the permit and when the inspections happen.
Pay in steps as the work is done, and keep every receipt and change order in writing.

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.

New York City rules

Anyone doing home improvement work on a home in New York City needs a Home Improvement Contractor license from the Department of Consumer and Worker Protection (DCWP). Check it on the DCWP online business search.
Licensed contractors must join the city's Home Improvement Business Trust Fund or post a surety bond.
Many jobs need a Department of Buildings permit, and sidewalk work needs a Department of Transportation permit. You can look up permits for an address in the DOB Building Information System.

How old are the homes in Upper West Side?

The Census counts about 131,397 homes in the Upper West Side ZIP code area (10023, 10024, 10025). About 58 percent were built before 1940, 83 percent before 1980, and 8 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.
