    "We had been looking for a pro to finish the basement for a few years. The previous company we had tried to work with had fluctuating pricing and very difficult email correspondences (time wise) in addition to putting us off for 6 months. I gave up trying. I looked on Home advisor for a pro and found Living Stones. Adam was prompt returning my initial email, set an appointment to look at the job, very quickly gave an estimate and was ready to get to work the following week. The framing and drywall was completed in 3 day! I highly recommend Living Stones Construction Management."

    "This company is the best I have encountered in many years for home upgrades. Connor Theriault was the expert who custom upgraded my exterior gutters. Connor did an amazing job cleaning out 3â of caked mud and leaves. And covered all gutters w metal mesh to avoid future blockages. Connorâ s attitude, skills, and workmanship are outstanding. As a retired federal Human Resources executive, I can say Connorâ s performance would get a healthy bonus award from me. Connor treated me kindly, explained everything clearly and treated me with great respect. I encourage you to recognize his excellence, always on time, technical skills, and very articulate. I usually dread workers on my property but must say it was a joy when Connor was here with his easy respectful demeanor."

    "We needed a new sliding glass door. The old one let in both the cold and the heat and unfortunately it didn't lock all of the time. After researching several companies, we contacted Champion Windows of Denver. They sent Joe B. and Joe C. to our house to tell us about their products. Both men were extremely professional and knowledgeable. After a few short weeks, our new sliding glass door was ready to be installed. The installation crew was professional, polite, and experienced. The installation was completed in less than two hours! We are very happy with our new Champion Windows sliding glass door. Got Windows? Then you MUST call Champion Window! You'll be totally pleased with their products."

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.
