"Our kitchen remodel turned out beautifully. The new layout is so much more practical, and the upgraded cabinets and countertops give the whole space a high?end feel. The crew stayed professional throughout the project and kept everything tidy while they worked. Truly impressive craftsmanship."

"Zacarias Remodeling Construction did an amazing job on my brand new kitchen! I wanted my kitchen to be done before Christmas and they worked above and beyond to complete it! Oscar (the Owner) would come to see how the project was progressing and inspect the finished work and made sure if we had any concerns or questions. The workers are professional and hard workers!! They also made sure everything was clean before leaving for the day. Suzanne (Estimator/Designer) was there 100% of the time for questions, advice and opinion on the design. Awesome to work with! I am very happy with my kitchen and highly recommend them!"

"Michael and team did such an amazing job on our bathroom remodel. They took our tiny, dysfunctional bathroom and turned it into a true master bathroom oasis in a short amount of time during the holiday season. When they had the space down to the studs, Michael sat down with us and discussed in detail the best possible use of the space and we couldn’t be happier with our final decision after going through the options. Michael was great at communicating and we still stay in touch to this day, which we truly appreciate. Great team who does great work and I will absolutely be giving Waters Construction a call for any and all future home renovations. I’ll let the pictures do the rest of the talking."

"Our goal was to build a structurally safe garage storage loft. Juan and Julian were a great team to work with. They were very professional and organized- they gave us a quote and clearly communicated what the plan would look like from beginning to end. They guided us on the items that we needed to buy prior to starting the work in order to complete the project within the estimated time. They suggested modifications that were minor fixes but made the layout make more sense in terms of placement. Their crew finished a day ahead of schedule. They kept a clean work site and the quality of the results were great. I would gladly work with them on another home project in the future!"

"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!"

"We had our two bathrooms fully remodeled by Golden View 4 years ago, and were very happy with the results. Recently we noticed a leak from the shower in one of them that was affecting the nearby flooring. Asaf and the team really came through for us, they diagnosed the problem - a shower pan leak - opened the walls to clean and mitigate mold, planned and executed a partial demolition and rebuild of the shower including an improved method for waterproofing, and restored the bathroom and walls back to original condition and full functioning. All of this and they didn’t charge us, since Asaf told us he wants to stand behind their original work and fix problems arising. Five stars for sure!"

"We hired McCormick for a bathroom remodel, and the whole process was smooth and professional. Khaled helped us make smart choices on design and materials that worked for both our budget and style. Now, our bathroom feels like a spa every time we step in. I appreciate the quality and attention to detail. These folks definitely know what they?re doing!"

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:
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.
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.
