Additions and Remodels
"Stop your search now, you've found the contractor you should go with, you will not be disappointed! This is the second project I've had Ben and his team do at my house and they knocked it out of the park again. This time around they remodeled two bathrooms and put in a new hall closet. They were rock stars throughout the entire project. There wasn't a single time that any reasonable request I made was denied. This was a huge load off my shoulders when dealing with such permanent decisions that comes with bathroom remodels. They were very patient and understanding as I ran into several supply issues that were out of my control during the project as well. It's very obvious that he's had years of experience with construction. His attention to detail and his forethought allowed my wife and I to rest easy knowing that they would always be able to bring up potential issues as well as offer us solutions to issues that we were going to run into many steps down the line."

Great guidance, from the construction stuff we don't understand to the aesthetic discussions we much appreciate. Done on time, and with great clarity around the billing. And the crew was great -- neat, thoughtful, on time, helpful. A big thumbs up."

"HIC builders is a family owned company, and they did a terrific job at my house. We added an ADU above the garage, remodeled two bathrooms, and did other extensive work on the house. Abraham, the field manager, was responsive and available, flexible when plans needed to change to accommodate structural issues that we discover as the project progressed, and answered my endless questions. The workmen were always on time, courteous, and cleaned up the site every day before they left. Probably the easiest way to find out if HIC can provide what you want is to call Abraham Moryossef directly (818 850 5062) and chat. I know it will be a good investment of your time. They are terrific!"

"I had such an amazing experience working with Idan Mizrahi, Cleber Cuzziol, and the rest of the Home Renew 360 team! I had a full bathroom remodel completed and the process was as smooth as it could be. Idan and Cleber were fantastic with communication and facilitation throughout the entire process, while also making sure that my full vision came to life within my new space. As a first-time homeowner, I am so grateful for their assistance and guidance throughout this entire project. I will definitely be recommending their team to my neighbors for any home improvements in the future!"

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.
