How does InstaBids work?

InstaBids does not hold payment for the work; you pay the contractor directly on the terms of the bid you accepted.

Each bidder appears under a stable label such as Contractor A, so you judge the work, not the brand.

Contact details stay hidden until the homeowner picks a contractor and they confirm the connection.

The contact-detail filter can miss disguised contact details.
