Why Deck Railing Matters?
Safety is the baseline, design is the opportunity. Every deck over 30 inches high in Colorado requires railing by law, but at Alta, we go far beyond code. We believe deck railing systems should be an architectural enhancement, not an afterthought. That’s why our deck railing projects are designed to integrate cleanly into the deck’s form and flow, improving views, increasing usability, and adding polished structure to your outdoor space.

What Our Customers Say About Us
EXCELLENT Based on 40 reviews Posted on Google Benjamin PaigeTrustindex verifies that the original source of the review is Google. We had a great experience working with Alta during the quote and planning process. They were professional, responsive, knowledgeable, and very generous with their time. We really appreciated their honesty, integrity, and clear communication.Posted on Google Sophie ParkerTrustindex verifies that the original source of the review is Google. Alta put a louvered roof over our existing patio instead of replacing everything. Saved us money and time. Jon Potter explained that our concrete was still good, just needed the cover. The Azenco system they installed works with a remote - open it when we want sun, close it when it's too hot. Simple concept, works exactly like they said it would. Crew was professional, in and out in under a week. Good experience overall, would recommend them to friends in Greenwood Village.Posted on Google Lee RodgersTrustindex verifies that the original source of the review is Google. Our house in Cherry Creek is older, built in the 80s. Wasn't sure how a new deck would look with it. Dave Little took time to match the style instead of just slapping something modern on there. The privacy screens they designed fit the architecture. This deck builder actually cared about making it look right, not just functional. My partner was worried it would look out of place but it doesn't. Gets compliments from neighbors pretty regularly.Posted on Google Gabriela PerezTrustindex verifies that the original source of the review is Google. Wasn't sure about spending this much on a deck. Jeff came to our place in Larkspur with actual samples, not just pictures. Showed us what composite looks like after a few years versus new. That helped. Jon Potter walked through the cost breakdown so we understood where the money was going. Decided to go for it. Four months later, using it almost every evening. Turns out it was worth it.Posted on Google Amber JenkinsTrustindex verifies that the original source of the review is Google. Finally have a patio we actually use in the evenings. The fire pit Jeff Potter helped us design sits perfectly with our new deck and railings, and the cedar tongue-and-groove cover overhead keeps us dry when the weather turns. We're in Colorado Springs and weren't sure a Castle Rock company would want to make the drive, but they never once made it feel like an inconvenience.Posted on Google Rosie SmithTrustindex verifies that the original source of the review is Google. Our deck in Larkspur was too hot to use most afternoons. Jon Potter added a louvered roof that we can close when the sun hits. Simple fix, works great. They also replaced the railings with something sturdier. My kids lean on them constantly and they haven't budged. Project stayed on schedule.Posted on Google Logan HayesTrustindex verifies that the original source of the review is Google. Jon made everything clear, he was upfront about the cost and timeline, so there were no surprises at all. We had a louvered roof installed over our patio, and it turned out perfectly. The water now drains away from the house instead of pooling, which was a big issue for us before. The whole project was completed in just three weeks, and we’d definitely use them again.Posted on Google Miles HendersonTrustindex verifies that the original source of the review is Google. We were surprised at how easy Jon Potter made getting our deck approved and built. He handled all the paperwork and even accompanied us to the HOA review meeting, which really made a difference. The deck builder and privacy screens his team designed got approved on the first try, something that rarely happens in our neighborhood. The crew was respectful and quiet while working, which we appreciated since most of us work from home. Eight months later, the deck still looks fantastic and hasn’t required any maintenance.Posted on Google Jared WatsonTrustindex verifies that the original source of the review is Google. We were initially told by several deck builders that the cost to engineer a deck would be very high. Jeff Potter saw it differently and proposed a much simpler solution that fit the terrain perfectly without overcomplicating the design. The end result was a multi-level composite deck that feels natural and thoughtfully planned, not forced in any way. We later added an Azenco roof, and it blended seamlessly with the original deck layout. The pricing was fair, the project stayed on schedule, and the crew always made sure the site was cleaned up at the end of each day.Posted on Google Penelope CastilloTrustindex verifies that the original source of the review is Google. We wanted to upgrade our deck in Monument without starting completely from scratch, and this team delivered exactly that. They reused the existing posts, which saved us a lot of money, and only replaced what truly needed work. Dave Little’s crew was efficient and thoughtful throughout the process. Jon even caught and fixed a drainage issue that no one else had brought up. The new Azenco louvered roof is perfect for adjusting shade, and since the project was finished in May, we’ve been using the deck almost every day.
