    "Westec Builders did such a great job with adding an entertainment room to my house! We had wanted a bar and hang out area and wasnâ t really sure where to start. Robert and Jeff met with me and helped me design what worked best to add to our house. They were always on time and professional and really knew how to help with every question I had. With covid, there were unfortunately delays, and they handled it all perfectly and kept in communication with me the whole time. My bar and room addition came out so beautifully, I will be using them for any future projects I have."

    "We were thrilled with Ubora Build! Because they did such a great job on our first bathroom (a year ago), we asked them to also do our Master Bathroom. Ubora Build was so nice to work with; they communicated exactly when they were coming; they listened well to what we wanted; they cared about details; they were conscientious; they were talented; their pricing was very good; and they cleaned up so well after they completed both bathroom projects!"

    "Peak Builders & Roofers of Denver have once again proven that they are unbeatable when it comes to the quality of work, customer service and price. Upon doing our bathroom remodels they have exceeded our expectations by showing up on time every single day, cleaning everything after them and making sure to update us by the end of day what will the scope of work be like the following day. The bathroom designs are phenomenal and we are looking into working together again in the future."

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.
