"We had a great experience with First Class Building and Remodeling and would hire them again for future remodeling projects. Glenn, owner and operator, cares deeply about the product quality and ensuring that the design is optimized. His ideas enhanced the project, which transformed the new addition space in our home. Glennâ s â Remodeling Roadmapâ project management system kept us informed on next steps in the project and importantly, enabled our addition to be completed in the time-frame we wanted. Glenn has spent many years developing his network of subcontractors, which were reliable, friendly and did great work. We are very happy with our addition and the quality of the work that First Class delivered, and look forward to many years of good use! -- David Moskowitz cell: 202-280-0888 email: [email protected]"

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.
