Additions and Remodels
"We hired Ben to remodel our living room and kitchen, which included adding approximately 300 square feet, creating an open floor plan, and removing an enormous brick fireplace in the center of our house. From day one, Ben was amazing to work with. He was on budget, on schedule, professional throughout the entire project, and consistently anticipated potential issues before they became problems. His wealth of experience was incredibly valuable when it came to making decisions along the way, and he was always willing to offer thoughtful advice and guidance. His entire team was fantastic as well: professional, respectful, and clearly committed to doing quality work. We couldn’t be happier with the results and our experience working with Ben. We highly recommend Ben for any remodeling, building, or construction project!"

Addtions Remolding
"Unique Home Design & Remodeling were hired to demolish and rebuild our master bathroom. The remodeling included everything such as the: bathtub, large shower, 2 sinks, custom size vanity, toilet, several mirrors, new lighting fixtures including LED lights, heater and fan inside the ceiling, new paint, new tiles on half walls all around and new marble floor. This whole remodeling project took them 3 weeks and Steve who handled everything, made sure to keep it at the same price that was agreed before we approved the work. Their price was significantly lower than the other 3 estimates that we got from other local contractors. The installers and sub-contractors came to work on time and they worked (Monday thru Friday), respectful, well-mannered, careful and qualified. We will hire them for their services again without any question or doubts. They also made sure to cover all the floor near the working area and carpets to prevent any damage to the house. They also blocked off with plastic sheets the nearby bedrooms in the house, such as the living room and dining room."

"After having remodeled our kitchen several years ago, we had KN remodel our master bathroom. Great guidance, from the construction stuff we don't understand to the aesthetic discussions we much appreciate. Done on time, and with great clarity around the billing. And the crew was great -- neat, thoughtful, on time, helpful. A big thumbs up."

"The windows I can't say enough good things about Universal Home Design. Ouriel is a great contractor,who is all about details and quality work. This is the second time I have worked with him. The first time he helped me remodel my kitchen,it came out beautifully. I recently had him put in new windows in my condo( 10 windows). He worked with me from start to finish. He was very knowledgeable about the windows and helped me with all the questions. Even after the work was finished he called me to make sure I was happy with the job. Universal Home Design is definitely one of the best. sincerely,Daniel M. The windows I can't say enough good things about Universal Home Design.

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.
