"This was quite a project - both my porch enclosed and a bay window replaced; I had very high expectations and I am very particular. Past project experiences with other companies were horrific, so to say I was skeptical at the best is t put it mildly. Upon completion of both projects, I am beyond pleased- they look BEAUTIFUL! Workers were timely, polite, thorough. A particular praise for Dolores Martino- she was my constant contact person; always available, always polite, always patient.: in times where customer service is severely lacking, she shines bright. Project manager Chris was also wonderful - both of them always made me like my satisfaction was priority. This was truly a wonderful experience."

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.
