"Michael and his team did an amazing job remodeling our kitchen. From start to finish, they were professional, reliable, and paid close attention to every detail. The quality of the workmanship exceeded our expectations, and the finished kitchen looks absolutely beautiful. The project stayed organized, communication was great throughout the entire process, and the crew always kept the work area clean.

"They are very honest and professional. I would highly recommend them to anybody."

"We had a wonderful experience with Steve on our bathroom remodel. We are fairly new homeowners and this was our first experience with a contractor, and we wouldn't change a thing. He did literally everything - installed a tub, did some beautiful shower tile work, plumbing, painting, electrical work, replaced drywall, window replacement, floor install, and more. Not only was the quality of work impeccable, he made sure to keep in constant contact regarding any unanticipated project changes and how they would impact the schedule and our budget. He showed up on time, kept the space clean, and simply did what he said he would do, when he said he would do it. I'm not sure you could ask for more. We look forward to having him back for other projects."

"I needed plans for a two-car garage of a certain size and roof pitch. I could not find stock plans of specifically what I wanted. Richard was very prompt and helpful, produced the plans and arranged for an engineer's stamp."

"I had an outstanding experience with Real Painting and could not be happier with the results. The painting looks fabulous, and the service was of the highest quality. I received quotes from four painters, and Carlos compared very favorably in both price and expertise. Carlos accommodated every request I had to make adjustments to my project and made himself available whenever I tried to reach him. He was extremely knowledgeable about which paints would work best for walls, cabinets, ceilings, and the moisture levels in each room, as well as ways he might work with me to maximize efficiency while reducing costs. His team was highly professional, courteous, and skilled. They carefully wrapped and taped my furniture and home items in every room, always removed their shoes when in carpeted areas, and took great care to protect my home throughout the process. Carlos was referred to me by my realtor, who has had him paint her properties twice. After seeing the excellent work he and his t"

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.
