Ask Baily instead of Sweeten + Thumbtack
Sweeten + Thumbtack publishes a directory — you still have to call 3–5 contractors, chase quotes, and vet licensing yourself. AskBaily scopes your Williamsburg project with AI, then routes you to one builder who has already cleared NYC Department of Buildings permit + overlay checks for the loft conversion + rowhouse + new condo your home likely is.
