"Ismael and his crew always cleaned up at the end of the work day. Ismael kept us informed of the condition of the siding as he and the crew worked. Ismael was onsite working along with his crew, and they all worked hard. Everyone was professional, friendly, and the work was done timely. I'm very happy with the completed job and will definitely call him again for future jobs."

"Noah and his crew worked fast and built exactly what I asked for! We wanted a covered space on our deck to enclose it for a catio, and they understood my vision perfectly. They even framed out a door with a secure latch so our cats cannot escape. We are DIYing the rest of the catio build, but if I need any more help on this or future projects, I wouldn't hesitate to hire Noah!"

Decks, Bathroom Remodels
"We needed our deck redone so it is all one level and a new patio/deck cover installed. This was not an easy task because they had to raise portions of the deck and run the boards in one direction. All of this with using only the existing decking. They did an amazing job and the deck is actually more solid now than before. They did everything we asked of them and then some. The patio/deck cover is top notch. It is a 16 foot by 30 foot cover so it is not something small. They used joist hangers and hurricane braces so this cover/awning will never move. There are a lot of words there to say that we would absolutely hire this company again. The whole crew is professional, experienced and customer friendly. Amazing work. Thank you."

"We started with one project with Mass Design, and were so pleased with their work that we added two additional home improvements as well. They truly care for their clients and go above and beyond when working to meet their needs. My wife and I found it surprising how carefully they listen. Things mentioned as a passing comment were noted and acted on. Their workmanship and design skills were exceptional, their communication clear and concise, and we were never left in question about any step of the process. In addition, we truly appreciated their honesty and transparency. Simply put, fantastic to work with. I would highly recommend using their services and we have more projects down the line where we will be using them."

"First off, I was impressed that this was the only contractor of three willing to take on the small job I needed. And it turned out to be outstanding quality, extremely well-built, and reasonable in cost. Plus he was on time, very personable, and knowledgeable. We have a couple more small projects down the road, and I'll definitely be calling Jay Bemis 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.
