"Really happy about my bathroom renovation. Working with these guys was great! Their project manager, Zamir was transparent to me and my family about prices and costs, and he also brings a creative edge to his work. The rest of the team are just as great, they all have great humor, and really get to job done. Jose on the tiles in particular really stood out. Overall very happy with the work, idea came to life!"

"I had a second storey addition completed by Rose Remodeling, and the results are truly amazing. The team did an outstanding job blending the new structure seamlessly with the existing architecture so that it looks like it was always part of the house. Adir guided us through every step, answered all of our questions, and kept the process stress-free. We now have the extra space we needed, and the work exceeded all of our expectations. Highly recommend their services."

"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!"

"Excellent Architect We hired SSA, Inc. for the exterior and interior remodel of our Autobody shop building. It is a challenging project since the building was never upgraded to be current code compliant. There are existing items to be legalized as well. Sharmila, Owner/Principal Architect is very knowledgable, experienced and familiar with city process, current building and fire codes. She is very personable, creative and suggested solutions and design that are both effecient for our setup as well as acceptable by the City. She and her competent, effecient team of engineers delivered design plans, renderings, drawing sets in a fast paced timeline so we do not have lags in our operations. SSA, Inc and team have expereince working with the building departments in all cities in the bay area. They communicate promptly and effectively with plan checkers and building officials. She is a fantastic architect who always works for the best outcome for her client. We are very thankful to have hired her and highly recommend her companys services for your remodel, addition or new construction project."

"As soon as my new tile flooring was installed, everyone who entered into my home immediately complimented on how nice it looked. It definitely made a huge difference after replacing those old carpets which had stains all over them. I am glad that a friend of mine referred me to Bayside Builders because they really do take care of their clients and provide excellent service."

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.
