"I had a great experience working with Ron and Juan. We met and discussed my ideas. They demoed my old patio and slab and build a beautiful new one. There was ongoing communication throughout the process, very appreciative. I would use them again. I'd highly recommend contacting Ron and get a quote."

"DS Builders are very professional. I highly recommend their services. I have recommended them to my friends. I have used their services 3 separate times, deck repair and the remodel of 3 bathrooms. Currently, they are working on the remodel of our kitchen. They arrive when scheduled, finished job is just as quoted and clean up is as you would expect. They are helpful in suggesting ideas that I had not thought of. Mindful of a budget is another bonus of DS Builders."

"We hired Brian Byrne and his team for several upgrade projects. They updated the siding and trim on nearly half of our house which came out perfect. We also wanted a custom farmhouse look with stained wood beams above our garage and front windows, he far exceeded our expectations and we get constant compliments from our neighbors. After this project we hired them again to replace two sliding glass doors that were outdated and they came out great! I would highly recommend them and plan on hiring them again in the future. Bryan is professional, always on time and easy to work with."

He completed what others seemed unable to do, all while ensuring highest quality and my specific wishes were met. He is easy to communicate and work with. We strongly believe we would not be in our beautiful new home today without Mark Whitney."

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.
