"We had an amazing experience

with Keystone from start to finish! Once we saw the design, we knew immediately that this was the company to help us make it happen. I would recommend working with Keystone if you want a beautiful living space and the job done right!"

-Kristin Borelli 

"Our experience was nothing short of incredible.

From initial concepts, to renderings, to picking out materials in the showroom all the way through to final construction with Jonathan and his team it’s been flawless. They were all extremely professional, courteous, hard-working and so easy to work with."

-Lisa Graham

"Simply flawless from start to finish.

My wife and I wanted to upgrade our outdoor living space for a few years and looked into 5 different contractors. Keystone was the only one that provided detailed renderings that truly showed us exactly what our space could look like before we even committed. Additionally, they took our interests and enhanced them beyond what we could have imagined in a way the other contractors overlooked."

-Benjamin Feinberg

We know what it feels like to not love your outdoor living space. That is why we have been making our client’s outdoor living dreams a reality for over 30 years.

"This was the second deck we had Keystone build for us. They did such a great job at the first house that when we moved we decided we wanted to have them build one here.

As before, the team did an amazing job. Everything is perfect, and by that I mean they wouldn’t leave until they achieved perfection by their standards and mine. It’s a level of detail and customer service you just don’t get from most companies.

You must visit their showroom, too. It’s an experience and they treat you like family."

-TB Fox
