Word of the CEO

Over the years, we have gained a reputation as a decent, reliable contractor and we value it very much. Each object is special for us, even if it is performed according to a standard project. I sincerely believe that we have a bright future ahead of us and more than one hundred successfully implemented projects!

Rob McDonald

President, Excel Custom Decks


5 stars! Excel Custom Decks has remodeled my previously damaged deck and it has been vibrant and unfazed for over five years now, and I was impressed with their attention to detail. They truly go above and beyond! My deck continues to stay beautiful year after year.

Sarah Contino
Small Business Owner

We had our deck built on our new home through Excel and they have done such an incredible job communicating and doing immaculate work on it itself. They did everything as efficiently and quickly as possible. We are very happy! Thank you again to the Excel team!

Austin Further
CEO & Founder

Outstanding Custom Builders, They just finished our Pool House, they clearly understood our wants/needs and stayed within our budget. Quality work, Great communication. Unlike many builders that tell you what you want to hear, Excel was always honest and made us feel at ease.

Scott Kinowski

Ordered the service of major repairs of the kitchen. After submitting the application, we were quickly contacted and clarified all questions. The experts arrived the next day, estimated the amount of work and the price, and then started working. We did everything as efficiently and quickly as possible. We are very happy!
