"Second floor full bath remodel, 65+ year old house: required down-to-studs demo and removal of 3-inches deep cement flooring, heavily tiled lath/plaster walls, and cast iron tub, with all the unknowns of older construction and some tricky constricted spaces for rebuild & tiling. Even in his initial assessment before hiring, Chris was generous and helpful with his time and ideas, and throughout the job his enthusiasm and confidence were constantly reassuring. He and Jamie were skilled and knowledgeable, worked diligently start to finish, no lags and no mess, and with careful attention to quality and detail. Unanticipated problems were solved with thoughtful craftsmanship, and ownerâs requests were always met. We now have a plumb and beautiful new bathroom with all the features desired, completed in record time. One of our best experiences with a contractor, ever."

"I needed to have the old flooring removed and the new flooring put down. They team was very professional. They realized the subflooring was messed up in a section and made sure to stop and communicate so the job can be doone correctly. I appreciated that factor and was able to approve a replacement of the messed up board the great thing was they were still able to finish the job in the time frame they originally stated! I plan to use them for all jobs moving forward. Priced fair,quality work, and friendly and professional!"

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.
