    "William was so responsive, professional, and talented. He was able to replace our old wood deck in less than a week. He made sure he gave us the best deal possible. He knew we were on a tight budget and gave us all the possible options. He was so kind and great to work with. I hope we can use his services again."

    "My basement finishing project was seamless. After getting several bids and designs, I went with Will, who meticulously went over everything, through permits, materials, and the overall concept including pointing out things that I hadn t considered that I am so glad I did. The project turned out fabulous with no issues during the project outside of normal expected issues when working with construction. I would hire Will again for any future needs as I always knew what to expect, there were no hidden costs, and changes were flawless."

    "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."

    "Ben Muck of A & M Landscaping turned our backyard into a sanctuary. It is now my favorite place to be, in or outside of my house! Whether for socializing, or recharging alone, Ben created spaces that are comfortable, functional, and beautiful. He was easy to work with, pleasant, informative, and professional, and delivered above and beyond all we had hoped for. Our backyard renovation was especially important to my husband and me, because this is our first house, and it was inheritance money from my grandparents that provided for the project. I told Ben that it was at their house as a child that I learned the joy of â visitingâ with loved ones outside. Ben designed a space Grandma and Grandpa would have loved, and I am so very grateful."

    "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.
