     Trustindex verifies that the original source of the review is Google. Harmony Decking did an amazing job creating the backyard space that I always wanted with a new trex deck, patio, and utility space connecting it all!  They helped refine the design that was in my head and made it better than I imagined. They easily made adjustments when we ran into some issues and kept the whole project on track.  They are a fantastic team to work with and I highly recommend them.

The original build from 6 years ago had some unfortunate issues ( they did not build the original stairs ) which Harmony helped to correct and repair. They helped immensely fixing things the right and safe way . They were prompt , cleaned up , and kept us updated throughout the process . I would happily use them again for any future projects .

Steve and his carpenters are professional and courteous and handled the job with expertise and excellence.  Harmony was able to replace our existing stairs with Trex, using both our pre-existing stringer and previously installed railing.  Their pricing was very fair and the timing from request to finished project was quick and efficient.  We are very pleased with their workmanship and our overall experience and would highly recommend their services.

Steven listened to me during the design phase - and put together a project design that exceeded my expectations.  The crew that built my new deck was clean, timely, respectful and true craftsmen you went the extra distance to build a quality deck that I will be able to enjoy for a long time to come. There was clear and continuous communication about the progress of the project and at no time did I not know where we were - and it was so excepting to come home each night to see the progress!  Highly recommend!

     Trustindex verifies that the original source of the review is Google. Can’t say enough about how great Steve and his team were during the process of updating our deck.  Steve was thorough and honest with his evaluation of our 25 year old deck and never made us feel like he was trying to have us spend a penny more than we had to. We had little to no wait time before the project was started and the teams were there working diligently everyday. They did a great job with much attention to detail. We are thrilled with how the deck turned out. We also had Harmony update our walkway leading up to the deck which they did beautifully. Very happy with all results and highly recommend Harmony.
