"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!"

"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!"

"Our room addition project turned out even better than we hoped. The Rose Remodeling crew was efficient, professional, and respectful of our space. They worked diligently to finish on time while keeping the disruption minimal. We appreciated how often they communicated, providing updates at every stage so we always felt informed. The craftsmanship is excellent, and the addition blends seamlessly with the rest of the home. They truly made the process smooth and stress-free."

"We had a major kitchen remodelling project in our house including new cabinets, countertops and flooring. Even sinks were replaced. We expected a lot of headaches, delays and unexpected charges. With Spenser and his team none of that happened. He explained from the beginning what our options were, he gave his recommendations that we found quite reasonable. The job started when he said it would and he was regularly checking on the progress. Everything that we wanted to fix (and it wasn?t much) was done at no cost. They did an excellent job, the kitchen is beautiful!"

"They were reasonably priced, were on time, worked efficiently and quicker than I expected, and cleaned up everything afterwards, making sure there were no nails for my cars, kids, or dogs to find. Great craftsmanship and skill. They also installed a solar light with minimal mess that looks and works well. I would 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.
