"Everyone we worked with at Greenstone - Mark Sr, Mark Jr, Laura and the crews - were just terrific in every way. We got a fast response and visit from Mark Sr for a quote. He knew exactly what we wanted and they completely redid our flagstone front walk - over 12 years old and now looks brand new - and built a new brick landing with a beautiful bluestone landing top and 2 steps. It could not have turned out any better! Mark Jr was able to find bricks to match our 27 year old home after I gave him the brick name we ordered way back when. It looks like the new landing / steps came with the house. The workmanship and attention to detail by the crews was amazing, precise and exacting. I cannot recommend this company enough - the end result exceeded my expectations. I would hire them again in an instant. Thanks to all who worked on our project, it is perfect."

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.
