"We hired David and Noah to do a gut renovation of our home in Santa Monica. We decided to hire them after interviewing six different contractors. From the initial phone call I had with the office I knew these guys were different. We were impressed to find that they were the only contractors to ask that I forward the blueprints we had so that he could come to the meeting prepared. When we met we immediately felt comfortable entrusting our new home to his company. Our project ended up being more difficult than we originally had thought. Some walls we wanted to remove were structural and almost every wall had plumbing. David and Noah, and their entire team handled each surprise like seasoned pros and these challenges did not stop their team from delivering the home we had envisioned. Santa Monica is also very strict with inspections. The office was scheduling inspections every time we needed and was very patient and professional working with the city. The quality of the work has been great and the team even occasionally reaches out to make sure everything is ok. I would not hesitate recommending them. At the end of the day they are really great people with a terrific team. They are professional and they stand by their work."

"I chose this builder from a list of 8 contractors who provided me with quotes. He was confident in the time it would take to finish my complete demo and build of the ADU on my property. Instead of telling me what he was going to do he took the time to show me several current projects he was working on. I was impressed with the quality of work and the speed in which his team built my project. He is our only contractor that we will work with from here on out."

"Creative Design went above and beyond the call of duty for our Project. Angiâ s Review should allow a category to be entered as well as a drop down list. We had a large and complex swimming pool completely removed and filled. Josh Bermudez was highly professional and efficient. He had the heavy machinery required to do this challenging job. He has knowledge of pluming, electricity, landscape grading and removal of concrete and rebar. His price was fair and the job was done quickly and perfectly. If you have a big landscaping job to do, Josh Bermudez is your man. His crew were also polite and professional. I want to adopt Josh Bermudez."

"I hired a large company who hired ProServ as the contractor for the project. My contractor was incredible and efficient. Regretfully the company was not. Carlos, ProServ owner, made an incredibly awkward situation work out. I would give ProServ and especially Carlos rave reviews. The professionalism and honesty of the contractor and his crew is exemplary and quality of his work is exceptional."

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.
