What Our Clients Are Saying
Just want to thank you for an outstanding job, from start to finish! The deck looks amazing! It’s hard to believe the transformation from the old deck to the new deck! Very professional job and your reluctance to not adopt the “good enough” attitude (as so many other contractors do) when it can be done better and right was re-assuring to us. Thanks again for a great job!
Jim and Sandy C. / Homeowners
Through a lot of wear and tear and 14 seasons of wet weather, Duradek has performed better than we ever expected. 120 steps (and ramps) walked on by almost one million customers, and still standing up. There is nothing else that works like Duradek.

Products We Use
Top-tier deck builders in Boulder CO know that quality starts with the right materials. We exclusively use these industry-proven systems designed for the Colorado climate:
Duradek™ Vinyl Decking
Duradek Vinyl Membrane is the ultimate PVC waterproofing membrane, offering a "one-and-done" solution for Boulder homeowners. It is UV-stabilized, slip-resistant, and provides a completely watertight seal that protects the wood framing underneath from all elements without ever needing to be stained or sealed.
Durarail™ Aluminum Railings
Our Durarail™ systems provide a sleek, modern look that won't obstruct your views. These powder-coated aluminum railings are engineered to be rust-proof and maintenance-free, making them a favorite for Boulder deck builders and homeowners alike. Our railings are safe, strong and require little to no maintenance.
Tiledek™ Underlayment
Tiledek™ is the top choice waterproof underlayment designed specifically for exterior tile, slate, or stone applications. It provides a permanent waterproof seal that prevents moisture from seeping into the structure, a critical feature during Boulder's frequent freeze-thaw cycles that can otherwise crack grout and tile.
