A person or business must be licensed under NYC law in order to work in your building, commercial property or residence.  While some companies promote themselves as Licensed they never provide you with their license number; THIS IS A RED FLAG.  Having a Non-Licensed person or business working on your property can lead to over pricing on work and delays in job completion.  The best way to protect yourself is to use a Licensed Contractor that abides by NYS laws and regulations.

Always ask your Contractor to provide you with their Contractor license number as well as Sales Person registration number. 

Always use a Licensed Contractor!!
