"I had rotting wood around my sliding glass door sill. After coming right out and assessing it, I was given a written quote withing a day. Everything was explained to me by phone. After me deposit, the project was started in little over a week. The workers presented well, were polite, and kept to task. I was kept appraised of their progress with pictures and videos of what they how found( a leaky aur conditioner near the door). All the rotting wood was removed as well as the mold. Everything was cleaned up nicely at the end of the day. The same crew was back at it the next day. The work was exceptional. Again I was kept appraised of their progress. The project was finished and another clean up was done very well."

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.
