Do you do the actual construction?
No. This is a matching site, not a contracting outfit.
Is a match always possible?
No. Coverage, qualifications, and timing vary.
Can a snapshot replace a site visit?
Rarely -- concealed conditions generally need an in-person evaluation.
Do multiple bids help?
For non-emergency work, comparing written scopes usually clarifies things.
Who's responsible for checking credentials?
The homeowner is, before signing off on any project.
