    "Jim was excellent! Jim added a new bathroom to our attic and built a new laundry room in our basement. He helped us develop a plan for the entire house and gave guidance without being pushy. Jim and his subcontractors were always friendly to our family and our pets. I highly recommend Jim and plan on having him do future projects."

    "Worked with me when the $50 a gallon "covers in one coat" paint took 3 to five coats. It was like he had to paint 3 houses not my small one. He's a highly experienced painter who "cuts-in" all the edges explaining that masking tape is for amateurs. A perfectionist in the art of painting! All ready hired him for 3 more projects!!"

    "Shawn did an excellent job replacing and installing vinyl skirting in the back of my mother’s mobile home. He also replaced boards around her shed. Both jobs were a job well done and he didn’t break the bank. I knew I wanted to hire Shawn at the time of the free estimate. He took out his measuring tape, measured, and looked at the project, stated what needed to be done with replacing the skirting, and sent the proposal. I signed and he did an excellent job. I would have Shawn again to do future projects."

It was a seamless experience and I could not have asked for more. Rick was great at communicating with me every step of the way and being transparent about all of the work that was being done to our house, He is very professional, very responsive and was able to answer every question I had.

    "Lisa and her crews remodeled our kitchen and great room. We are totally pleased with every aspect of the work and have received tons of compliments. We have had several gatherings since it was finished, and space worked out so well with plenty of room in the kitchen, dining, and living room areas for our guests. Before the remodel, the kitchen was congested and cramped. Now the whole room has an open, airy feel. Somehow Lisa created more space in the entire area which is especially apparent in the kitchen when several chefs are working. We are already planning to have Lisa renovate our master bathroom and bedroom. All of the subcontractors of Lisa were excellent. Lisa attends to every detail and makes sure everything is perfect. She is creative and fun to work with while being mindful of our budget. The entire project took only two months from a complete gutting to a beautifully designed and highly functional kitchen. We highly recommend Lisa Beach and Silver Lining and we look forward to working with them again."

    Professional, family owned, detail oriented

    "Once again and with the highest confidence, we hired Russell's Contracting to convert our back entrance into a more open, useful mudroom. As promised, they arrived on time on the expected date and started by sealing off the back entrance for dust. The demolition of the closet was first done, and then the rehab began. I was amazed at the level of detail necessary to make the new mudroom perfect. From fixing the ceiling to installing new walls, taping and sanding, painting, new baseboards, and moving the overhead light, it was fun to watch. Colby was professional, exacting, efficient, clean, and asked all the right questions to ensure we were happy with the result. The new mudroom is exactly what we wanted. In addition, we asked Russell's to help us figure out how to make our open staircase to the second floor safer. Keith, Colby, and Max designed and installed a custom-built, stair-to-ceiling railing system that looks great and provides the necessary safety we were looking for. They also made it removable to accommodate large objects up and down stairs. The amount of time they spent was crazy, and the amount of math they did to ensure it was plumb and solid was above and beyond our expectations. My house was built in 1933, and this railing system looks like it could have been original to the house. It is a masterpiece. Everyone at Russell's Contracting we have met and who has worked on our house has been exceptional. You can stop scrolling for contractors; call Russell's."

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.
