"Had him rebuild an old patio cover in my yard. All we kept were the posts and two beams. Replaced all else. Came out very nice. Couple months later had him do some porch railing and window sill repairs on a rental house my mother owns. Nice work, very fair price. Will definitely use him again."

"This company remodeled my kitchen and they were truly professional and completely honest from start to finish. Although there were some unexpected issues they resolved everything very smoothly. They also cleaned after themselves at the end of every working day. The most important they made amazing kitchen, beautiful design and quality. Excellent contractor, thank you Unique Home Design & Remodeling!"

"After they redid our counter tops and island, we had them paint out cabinets and build shelves up to the ceiling. The communication was on point this time and the results speak for themselves. Would definitely recommend them to anyone for any home project."

"One of the biggest benefits is the fact that they have both the home design and the building aspects of the project. The owner of the business is very creative and even after the design is completed, he still brings improvments to the design as it goes along!"

"Jose was friendly and professional. My job was not considered large by any means (re-hanging a gate) but he completed it in short order and cleaned up after himself. I really appreciated the fact he wanted to insure I was satisfied with the work because he needed to cut an inch off of the gate.....which I was. I would certainly call him again."

Frequently asked questions
- It’s important that you verify their license is still in good standing. Also keep in mind that certain states or provinces don’t require licensing if the job is under a certain dollar amount.
- You can find a list of your state’s licensing requirements on the HomeAdvisor website. Before you get to work with the pro, make sure their qualifications are current and acceptable to you.
- It is always a good idea to get a copy of the pro’s insurance certificate for future records, and in case anything happens. This is a good way to feel more secure in your home project, and to weed out potential scammers.
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:
- Have you completed a job like this before?
- Do you have a list of references I can contact?
- When are you able to start the job?
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.
- How many years of experience do you have?
- What’s your permanent business address?
- Are you licensed to work in my area?
- When did you earn your business license?
- How do you handle warranty service complaints?
- Do you have worker’s compensation, property damage and personal liability insurance?
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.
