    "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."

    "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."

    "Honeycomb helped save our house. As they were replacing our deck, they discovered rot and quickly removed and replaced all the bad material. They also discovered that we had a termite infestation. The issue was in the structure of the house. They assured us everything would be fine and efficiently dispatched all the rot and talked us through next steps with detailed recommendations, involving other contractors. The additional charge to remove the rot was minimal and I would have gladly paid 10x for the security of having a safe house. And just look at how beautifully it turned out. The photos really don't do it justice, when you get to sit out there enjoying a coffee in the morning or actually having a family gathering. It is such a game changer meeting space. Also, and it might seem like a little thing, but its the details that matter. It was really hard for me to get on my deck as a physically handicapped person. Taylor made it easy for me to go outside alone. I love you guys 11/10"

    "The doors on a new piece of furniture hung uneven and was very noticeable with the hardware. Torin was able to work magic and re hang the doors to make them all level! He also replaced the outdated hardware with new modern handles. I?m very happy and has improved the overall look of the room. Will absolutely work with Torin again on future projects."

    "Adam did an excellent job building our garage from the ground up. He was excellent to work with. Not only was he very professional, so were the subcontractors that he hired. Everyone was knowledgeable, helpful and friendly. Our project required that a road be built to accommodate large trucks in the springtime. The project stayed on track and proceeded smoothly. We were never left wondering “what’s next?” Adam has great communication and stayed in touch to make sure we knew what was coming up and when. I would definitely recommend using Magic Frog Carpentry."

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.
