"Yes. The remodeler was on time, worked efficiently, cleaned up after himself, and because Eric was experienced in remodeling, he knew exactly what to do so everything went smoothly. Thank you. The bathroom looks great!"

"They were reasonably priced, were on time, worked efficiently and quicker than I expected, and cleaned up everything afterwards, making sure there were no nails for my cars, kids, or dogs to find. Great craftsmanship and skill. They also installed a solar light with minimal mess that looks and works well. I would highly recommend them."

"Idan and the crew from Bear Remodeling were professional from the beginning to the end of the project. Idan communicated constantly and throughout the project and the results were better than expected in the full remodel of an upstairs bathroom. We will be using Bear Remodeling for our next project!"

"It's very rare these days to find a contractor that is both fair on job pricing and does exceptional work. Bay Quality is both. Benito and his team are not only easy to work with, but instill confidence in us in their work. Bay Quality has assisted our family with a bathroom, kitchen and basement renovation (all very uniquely different projects at different times in our lives) and I wouldn't trust any other contractor to get the job done so well. I would highly recommend this team!"

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.
