Deck and Porch Service
Yes, I recommend this pro
We hired John to replace and expand our deck. We knew from the first meeting with John that he was a very experienced, professional, and honest contractor. He was very easy to work with, got back to us in a timely manner with any questions or concerns, and worked within our budget. We also were extremely impressed that he himself actually did a lot of the work and was on sight most of the time with his team to oversee things! Our Trex deck could not have turned out more beautiful and we would highly recommend John for any job you need done!

No one else wanted to do the structural job we needed done to make our deck safe. Everyone else wanted a new build when the deck was still in good shape. I was so happy I found him to do the job that no one else wanted too.

John’s team completed a large front porch on our house. They were professional, dependable, and I felt very comfortable with them. The finished work is beautiful. I would not hesitate to reach out to John for our next project.

Over all the years John’s crew and his expertise has been resilient John’s upfront and honest and as far as I’m concerned, he’s the best general contractor around for what he does if he can’t do it he’ll tell you

John and the team reconstructed our deck and pergola with design and structural security. It is not only beautiful, but has added security and aesthetic appreciation to our outdoor space. They consulted with us on the materials that were high quality and practical for the application. The team worked together very well and were very respectful of our home and property. We are grateful to know John: we are always dreaming up improvement projects, and he is our "Go-To"!

I need a support column replaced on my front porch. John reviewed the project, provided an estimate and set a start date. He and his crew came and completed the project in one day. They cleaned up the area afterwards. Phenomenal work ethics and pride in their craftsmanship. I would highly recommend them and will use them again
