Our experience with Keystone Decks was impeccable from start to finish. The sales team was welcoming, worked with us on our vision and within our price range and was communicative up until construction began.

Once the building started, Dave and his crew were punctual, efficient, hardworking, communicative, neat and accommodating. Dave always gave me updates, asked questions and ensured that I was happy with the product throughout the entire process. His crew kept my driveway and backyard clean and safe and was extremely respectful of our home and small children. We are thrilled with the finished product and would use them again in a heartbeat.

Highly recommended!

- Elana

Excellent experience, impressive results. I went through several companies before finally going with Keystone (only because I was short on time and deck needed immediate replacement).

So glad I chose Keystone, from Ron in Sales to Brooke in Productions to the final installation by Foreman John Ervin and his team, Aaron and Mike.

Communication was top notch, deck installation was professional, clean, and respectful of my house and neighbors.

I can be kind of critical, but not with Keystone, every aspect of this project was easy, professional, and agreat relief as the final product came to life.

The final deck product is perfect and I'm looking forward to many years of enjoyment with the new deck.

- Daniel

We've had great experience with this company - from sales, design, showroom visit to scheduling, permits and construction... Everything went great - on time, great quality and attention to detail as well as communication with us. Everyone we encountered during the project was super easy and pleasant to deal with. Many thanks to Joe from sales, Justin for proposal/design work and our amazing construction crew (John, Aaron and Mike) as well as Trent, Ray, Amy, Brooke and probably others from the back office who took care of permits, scheduling and other coordination work. This company came highly recommended by neighbors and exceeded all our expectations!

2. Add a safety cover if possible

3. Alarms that sound when a person or animal enters the pool.
