"Not only did Eddie and Yesenia take care of our framing they also assisted us with finish carpentry and complete installation of the cabinetry. We were skeptical to hire them because they are a very new company but once we met them and understood Eddie’s decades of experience and their family oriented business we were very comforted. We also were helping our aging parents make their house comfy and safe to live their remaining years. MW was the only GC that aimed to please and work within our budgets. They also advised and predicted other costs that might arise so we could budget for it. At the end of the day the work was done timely and expertly. I wish the very best for this amazing family. They have truly become friends of mine. I an so grateful for what they have done for our parents. Thank you Eddie, Yesenia, and Lalo!!!!"

"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!"

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.
