    "Shawn did an excellent job replacing and installing vinyl skirting in the back of my mother’s mobile home. He also replaced boards around her shed. Both jobs were a job well done and he didn’t break the bank. I knew I wanted to hire Shawn at the time of the free estimate. He took out his measuring tape, measured, and looked at the project, stated what needed to be done with replacing the skirting, and sent the proposal. I signed and he did an excellent job. I would have Shawn again to do future projects."

    "Aubrey & Sons were terrific. They repaired a leaking seam between the house and porch. They replaced clapboards on the house and the roof on the porch. Their work was excellent, highest quality and fairly priced."

    Professional, family owned, detail oriented

    "We had 6 different contractors bid on our deck/porch & siding project, and Russell's was a clear standout right from the start. This was a sizeable project for us, and even though Russell's wasn't the cheapest quote we received, project manager Keith did something that completely set them apart: He simply stayed in touch. From start to finish, Keith was communicative, responsive and always made himself available. He listened to us, kept detailed documentation, and made us feel comfortable every step of the way. In just a few short weeks, lead carpenter Todd & his talented team completely transformed our home. Thoughout the process they were friendly, respectful, professional & attentive to every last detail. We are thrilled with the quality of their work, and we couldn't be happier with our decision to work with this company."

    "The biggest issue we experienced when trying to finish our basement and build out our mudroom was the lack of communication from most contractors these days. That completely changed when we connected with Mark and the team at Chasco. Mark was communicative, reliable and always followed up when he said he would. The thorough proposal made us very comfortable moving forested and the continuous communication throughout kept us confident that the project was being completed as expected. The work the team did was amazing. Weâ re extremely happy with our investment and our new mudroom + new basement!"

    "Rick White at Bradford construction really delivered for us in replacing an old sliding glass door in our new home. We'd placed an order for a new door with a big box store. After several weeks, it arrived damaged and we decided to seek new options. We found Bradford Construction on Angi and could not be more satisfied. Rick sourced a new door for us within a similar price range and kept us up-to-date and informed throughout the process.. Honest, professional, on-time and the team did a great installation job. We plan on working with Bradford Construction again and highly recommend them."

    "I hired Jim to update and re-model my bathroom, He did a great job, was always here when he said he would be. He arranged plumbers and electricians and made the reno as painless as possible. Jim is very communicative, willing to roll with the punches and smart. He had great advice, was always willing to work with me an within his quote, came in slightly under budget, even. The bathroom looks clean and bright. I'm very happy with the work he did."

    "Worked with me when the $50 a gallon "covers in one coat" paint took 3 to five coats. It was like he had to paint 3 houses not my small one. He's a highly experienced painter who "cuts-in" all the edges explaining that masking tape is for amateurs. A perfectionist in the art of painting! All ready hired him for 3 more projects!!"

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.
