They were kind, friendly and respectful. Their knowledge and craftsmanship was very impressive. We appreciated their flexibility when we asked to make some slight changes to the original design. They went above and beyond our expectations!

"We couldn't be happier with our new covered patio!!! Keystone Custom Decks did an amazing job creating a beautiful outdoor living space utilizing our existing patio! The new roof structure is seamless, it looks like it was built with the original house construction and is everything I envisioned. The 3D rendering was spot on, communication, professionalism, cleanliness, attention to detail...overall a great experience working with Mahlon, Nate and their team...they are truly hard working and seriously skilled craftsmen!!"

- Brian Felber

"We are so impressed with the quality and workmanship by Keystone Custom Decks on our new covered deck/patio. The crew on site was excellent and we could not be happier with the results. The whole company is very professional, they left the work area clean at the end of each day and put up with all of my questions regarding the build to ensure we received exactly what we were expecting. I have to thank Mahlon for accepting the project even though it is much further away than typically used to. Thank you again to the great crew for the long days and sacrifices away from wife and family. Can't say enough great things about Keystone. 6 stars and three thumbs up!"
