Who actually does the work?
An independently owned contractor licensed by the Maryland Home Improvement Commission. TBG makes the introduction; it does not perform or sell the work.
Does it cost me anything?
No. Matching is free to homeowners. TBG is paid by its partner contractors.
How do I check a contractor's license?
Every partner shows their MHIC number, which you can look up on the Maryland Department of Labor site. Contractors must also show it on their contracts, trucks and ads.
What happens after I submit?
