I highly recommend Custom Decks based on professionalism and quality of work. While they're competitively priced, the quality easily justifies the costPosted on David BruhnAugust 17, 2025Trustindex verifies that the original source of the review is Google. A shoutout to Custom Decks for the outstanding job they did on our outdoor living space. Steven provided excellent communication and assembled a highly skilled network of designers and subcontractors who met both schedule and budget constraints. Designer Kari found a way to minimize the number of posts required, effectively reducing costs. As a structural engineer, I truly appreciate the craftsmanship of carpenters Christian and Dylan in building our steel structure, composite deck, and roof. We were impressed by Nate’s meticulous electrical installation, and the contractors responsible for the footings, concrete, railing, and roofing were top-tier. We’ve already enjoyed countless moments on this deck with friends and family, and we know there are many more to come. We highly recommend Custom Decks.Posted on Samantha KramerJune 28, 2025Trustindex verifies that the original source of the review is Google. Working with the custom decks crew was amazing! George was super communicative, considerate, and worked through a heat wave to get the work done. Mikey, Lionel, and Christian were also amazing. We are so excited with how the roof deck turned out. Not only did they find our previous leak and fix it, the new install improved the usability ten-fold and looks stunning. Both our pets also loved getting bonus attention during the work day! Dog and cat approved! Thanks team!Posted on Sarah TakahashiJune 19, 2025Trustindex verifies that the original source of the review is Google. I reached out to Custom Decks about a small deck project, and while the job was too small for their scope, they went above and beyond to help me out. They referred me to someone who would be a better fit for the work, and when I followed up a couple days later with questions about that referral, they promptly gave me a call to share more details about their experience working with them. I really appreciated the time and care they took—even knowing they wouldn’t make a dime from it. That kind of integrity and helpfulness is rare and speaks volumes about how they run their business.
