    "Shawn responded to our request the same day. He diagnosed the location of a roof leak in a few minutes and repaired it immediately and then went onto the roof and noted that there were missing shingles on the back with exposed plywood. He completely replaced the roof a few days later and did not exceed his estimate for the job. We were very favorably impressed with his work ethic and his honesty."

    "Robert Aubrey responded to to my request within 20 minutes. He listened to my concern and researched possible solutions. The window in my door needed to be replaced. He searched places that carried the window and found a source that had it in stock. He was quick to pick it up and install it."

    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!"

    "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."

    "There are a lot of great things to say about Bill. First of all, he can do ANYTHING. Bill replaced siding, installed new plywood and Tyvec, painted my house and deck, built a new front porch, repaired and built new features on my back deck, eliminated rot, installed new gutters, re-insulated my basement, and even fixed a closet door in my house. He is a perfectionist and will treat your house like it is his own. Our house was in really rough shape before Bill came and now it looks stunning. We get compliments on it all the time. If you want someone that will do the job right, won't cut corners, and is a very nice person to work with - Bill is your guy."

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.
