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 75 million building permits, and over 80,000 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.

Here are some of the rules, regulations, and laws governing contractors in California

Does Tier One carry a valid contracting license?

In California, any remodeling or construction project that exceeds $500 (labor and materials), requires a contractor to have an active license with the California Contractor State License Board (CSLB).

Tier One currently holds license 669871 ((Electrical)), which was Active when we last checked.

How important is contractor licensing in California?

The CSLB is one of the highest rated licensing boards in the US. Applicants are required to pass a written board exam and prove at least four years of prior, relevant work experience. In addition, the CSLB requires all license holders to maintain at least $2,500 in operating capital and provides you with a range of other consumer protections.

Your liability risk when hiring Tier One

Contractors in California are required to carry workers' compensation insurance if they have employees and proof of liability insurance with the cumulative limit of $1 million for licensees with five or fewer persons, and an additional 100,000 for each additional member over five, not to exceed $5 million total.

Financial recourse when hiring Tier One

All licensed contractors in California are required to maintain a bond, which provides you with financial recourse in case they perform defective work or violate license regulations. If you feel as though you have been taken advantage of, you should leave feedback on the BuildZoom's contractor profile and file a complaint with the CSLB.

Tier One has a $12,500 bond with American Contractors Indemnity Company.

What else should I know before hiring Tier One

California contractors are required to submit their fingerprints to the board, which are then checked against criminal records held by the California Department of Justice (DOJ) and Federal Bureau of Investigation (FBI) prior to obtaining a valid contracting license.

How is the BuildZoom score calculated?

The BuildZoom score is based on a number of factors including the contractor's license status, insurance status, verified work history, standing with local consumer interest groups, verified reviews from other BuildZoom users and self-reported feedback from the contractor.

Why you should hire through BuildZoom

When it comes to major construction work or even minor alterations to your home, hiring the wrong contractor could result in incomplete or defective work. You may even find yourself dealing with huge liability claims. BuildZoom does the homework for you and helps you hire the right contractor.

You should get several bids before hiring a contractor

The California State License Board recommends getting at least three written bids before hiring a contractor. Do not automatically accept the lowest bid - an abnormally low bid may indicate the contractor made a mistake and is not including the same work quoted by their competitors. We've made the bid collection process extremely simple (and free). Just click here to get started.
