    "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."

    "I hired them to replace the railings along two second-floor decks. They did an excellent job, installing redwood railings with powdered-aluminum balusters and staining the redwood. They ran into a snag on one deck, because the boards underneath the railing had rotted from water damage, but they quickly repaired the frame and subcontracted the stucco repair as well as metal caps to prevent the wood from getting damaged again. Their whole crew is very polite and considerate of the residents and did not disrupt our lives any more than necessary. The owner, Brian Gorton, is a young fellow but is a good businessman and is very good at explaining the options. I enjoyed working with him and his crew."

    "This is a great company to work with. They kept us informed about progress of the project on a daily basis, they were tidy and considerate of us still living in the house during the remodel. The finished space is beautiful and was completed on time."

    "Any time you're hiring a contractor you have three questions about the project: Will it be done on time? Will it be done on budget? Will it be done well? After working with Nate and his crew I can tell you we can shout YES, YES, and YES! to all three of those questions! Once we laid out our plans and dreams for the bathroom spaces he was working on, Nate explained how he would accomplish the goals, gave suggestions to make our remodel better, and then worked early and late to make it all a reality. He was conscious of our budget on the project and went out of his way to keep costs down, but also never shied away from telling us where to spend more money to preserve quality. He knows his stuff! The bathroom on the main level of the house is literally a talking point for guests, everyone loves how it looks and it is so much better than we even imagined. If you're looking for someone to take your bathroom remodel vision and move to reality in the right time for the right cost, hire Nate and his team!"

    "Tim is not only talented and efficient he also has an eye for design. Tim was able to transform an old spare room into a beautiful guest room and I was able to trust him with picking paint color and light fixtures as well as flooring and additions. The room turned out better than I expected ! I would hire Tim again for more remodels and additions on my home because everything he does is well crafted and he has fresh ideas that can bring any project to life."

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.
