This team did a fantastic job on my little back porch in early 2025. They’re the first people I contacted for a much bigger job at the front of the house this year.

Jason did a great job on installing trex decking on my old front porch deck. I am so pleased that I now am getting a bid to redo my backyard deck!

Brought a portfolio of work to bid meeting, and was able to speak to solutions of my requested desires. Was quick in executing the job and the final product looks great

Jason and Devin did a great job on our deck!

From the beginning Jason reached out quickly and was able to stop by that week for an estimate. He was able to fit us in quickly in between projects and communicated when schedules might need to adjust. We ended up deciding to add an additional step that we hadn’t planned on at the start of the project. He was honest and realistic about when they could be back to complete it and ended up sending someone out from his crew, Devin, to finish it to ensure it was done timely.

As a woman a lot of times people look to my husband or talk over me, but Jason never made me feel that way as the person running point in getting this done at our house. He explained things with technical details and looked for my approval before moving forward. It was refreshing and an added bonus in my mind.

Thanks, Jason! We love our new deck!
