    "I recently hired Tomer from Verified Builders for a three-bathroom remodel at my home, and the results were outstanding. What impressed me most was the clear communication throughout the entire process. Tomer provided effective solutions quickly whenever challenges arose, ensuring the project stayed on track. He consistently stood behind his commitment to the timeframe, completing the work as promised without compromising quality. His professionalism and dedication made the entire renovation smoother than I had anticipated. I would definitely work with Verified Builders again and strongly recommend they services to anyone looking to improve their home"

    "Jason and his team did a remarkable job on my bathroom remodel. I shared a few photos to convey the concept and style I had in mind, and not only did Jason nail it, he added thoughtful details I hadn’t even considered. The final result exceeded my expectations, and the quality of the work is outstanding."

    "Greg did an excellent job with our flooring and went above and beyond our expectations! Others came in and wanted to laminate over the existing laminate flooring in our kitchen. However, Greg did it the right way and removed 3 layers of laminate and was able to save our existing oak trim in the process. He was also very efficient when it came to using materials. I would absolutely recommend Greg for any flooring installation projects!"

    "Christopher (Chris) can do any project. His estimate was the best out of three. He explains clearly what he will do. He puts it in writing. He did all the labor in the bathroom remodel, redirect plumbing, redirect wiring, installing the shower tiles and floor tiles. Helped us select our tiles, cabinets etc. He'll take you to stores to select tiles etc. He's very knowledgeable in selecting items that compliment the completed job. Easy to work with. He will become your friend."

Frequently asked questions

  • It’s important that you verify their license is still in good standing. Also keep in mind that certain states or provinces don’t require licensing if the job is under a certain dollar amount.
  • You can find a list of your state’s licensing requirements on the HomeAdvisor website. Before you get to work with the pro, make sure their qualifications are current and acceptable to you.
  • It is always a good idea to get a copy of the pro’s insurance certificate for future records, and in case anything happens. This is a good way to feel more secure in your home project, and to weed out potential scammers.

HomeAdvisor makes it easy to connect with pros near you. You can read reviews, get quotes and book appointments all in one place.

Depending on the type of project, you may find subtle differences in the hiring process. Here’s a look at task-specific advice.

You can use HomeAdvisor to help evaluate a contractor’s qualifications. We put pros through a screening process, and award badges to high-performing contractors. You can find these badges on a pro’s HomeAdvisor profile, and sometimes, his or her website. 

Your research doesn’t stop here. Once you’ve found a few prospective companies, make an call to ask a few questions about work history, licensure and more:

  • Have you completed a job like this before?
  • Do you have a list of references I can contact?
  • When are you able to start the job?

In most cases, the responses you get to these three questions will give you a very good idea of the right pro for your project. If you have more than one front-runner, these additional questions can help you narrow it down. 

  • How many years of experience do you have?
  • What’s your permanent business address?
  • Are you licensed to work in my area?
  • When did you earn your business license?
  • How do you handle warranty service complaints?
  • Do you have worker’s compensation, property damage and personal liability insurance?

Any good contractor will answer these questions, and most will appreciate dealing with a client that takes such an active interest in finding good service. On the other hand, if a contractor gives you a hard time with these questions, you probably want to find someone else.
