About BuildZoom

BuildZoom has one simple purpose: To help you find the perfect contractor.

How we do this is more complicated. BuildZoom is a database of every licensed contractor in the United States. We work hard to figure out who the great contractors are, and who the bad contractors are.

BuildZoom combines license information on 3.5 million contractors with 70 million building permits, and over a million reviews from homeowners and the Better Business Bureau.

If you are looking for a specific contractor and you can’t find them on BuildZoom, it’s likely that they do not have a license - please contact us and we’ll try to help!

Finding a Contractor through BuildZoom

The best way to use BuildZoom is to let us recommend contractors for your remodeling projects.

Homeowners who hire through BuildZoom's free bidding system report high rates of satisfaction, and homeowners who research contractors online are twice as likely to be happy at the end of their project.

If you hire a contractor through BuildZoom, that contractor is accountable to us. We can enforce standards of behavior, mediate disputes, and guarantee satisfaction.

Read more about why hiring through BuildZoom is so effective.

Why should I trust BuildZoom

We built this site to help people find great contractors, and to help people avoid bad contractors. We take this incredibly seriously, and we have a zero tolerance policy for contractors who don’t adhere to our standards.

1 million people use BuildZoom every month. Our business depends on their trust.

If a contractor does poor work, they will no longer receive leads from BuildZoom, and a negative review will be posted on their profile.
