• No worries. FH Builders are CO-OP and Condo approved. Building Management firms love to work with us because we are licensed, insured and LEAD certified, and we have never ever damaged any building or property. Ever. You can call consumer affairs to verify this. We know exactly what is needed to get your project approved by the management company. First step is to request for an ā€œAlteration Agreementā€ from your management office. Once you have obtained the agreement, forward us a copy and we will handle the rest and get you approved.
