"Gomez Vision Construction, LLC. Overall they did an amazing work on the construction of our sunroom. Jorge is a very professional, respectful and responsible Contractor. His Team is composed of members with the same professional skills. They are all knowledgeable, polite, punctual and clean. They left the place fully finished and up to our standards, everything was spotless. We are so satisfied that we already have another project lined up for him. Way to go, Jorge!!! Thank you so much for a job very well done."

"Terrific experience with JM Construction. We had major repairs done on our ancient garage, including pouring a new concrete floor. But the bigger job was the complete renovation of our kitchen, from the studs on out. New tiling, flooring including replacing a rotting subfloor, lighting, custom cabinetry with new pantry and attached broom closet, new island, sink, countertops, etc. Beautiful job and an appreciation for their creative problem solving will bring them back for even more work in our home!"

"The work, including making a wood frame for, and then pouring a 4" concrete foundation, followed by assembling a 10' x 8' toolshed was skillfully done. The work was very neat, completed on time and all the debris was removed. In addition, Kladji, the owner, was extremely good about returning phone calls and messages, and very easy to communicate with. I would highly recommend his services, which were priced reasonably."

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.
