"We hired Avis Builders & Design to help us with our bathroom remodel, and we couldn?t be happier with the experience. Since we live out of town, communication was especially important to us, and their daily updates and consistent communication gave us peace of mind throughout the entire project. Thank you, Avis Builders & Design, for your professionalism, attention to detail, and for making our bathroom remodel such a smooth experience. We truly appreciate all your help!"

"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!"

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.
