"Keystone Custom Decks is the absolute best. We had them build a custom deck & patio off our home in Newtown Square PA. The team they sent was very professional, courteous, skilled, kind, experienced, hard-working, and meticulous. They took care of any questions or needs we had immediately. The follow-up was great & the entire team at Keystone was just a delight to work with. We would highly recommend!!!”

We had a wonderful experience with Levi and his crew: Josh and Melvin. They were incredibly hard workers, so kind and friendly, and built our dream space. We developed such a great relationship with them that we were sad to see them leave. Keystone is very professional and delivers an exceptional product! We would recommend them to everyone!

- Elise

We engaged Keystone to construct a partially covered deck for us, and we couldn't be more pleased with the outcome. Daniel and his team displayed the utmost professionalism and courtesy throughout the project. Their craftsmanship is truly exceptional, and the level of service they provided exceeded our expectations. We are thoroughly satisfied with both the quality of their work and the overall experience. Highly recommended!

- Yi

Everything was perfect from the initial planning stages through the completed build. Everyone was better than we could have ever hoped for - sales, design, processing and building. We especially appreciated the crew's expertise, experience, workmanship and caring attitude throughout our project (which both started early and finished early). We would 100% recommend Keystone Custom Decks.
