When you think of installing a new deck, traditional wooden planks are likely to come to mind. While wooden decks possess timeless appeal and decent durability, they do come with their fair share of challenges.

Wood requires regular staining and maintenance, particularly if you want to prolong its lifespan. Additionally, it is susceptible to rot, which can be a concern in Colorado’s ever-changing and rainy weather, compromising the safety of your deck.

Fortunately, there’s an alternative that offers the aesthetic benefits of wood without the maintenance or rotting issues – composite decking.

Composite decking closely resembles wood but combines wood fibers with recycled plastic, resulting in a remarkably durable and wood-like material that resists warping, rot, splintering, and splitting. It also offers several other advantages, such as:

  • Little to no maintenance needed: With composite decking, you don’t have to worry about restaining or repairing damaged planks. All you need to do is sweep off your deck every now and then.
  • Highly cost-effective: Due to the impressive durability and minimal maintenance requirements, a composite deck is an incredibly worthwhile investment that can save you money over time!
  • Weather-resistant: From inches of snow to days of hot weather, Colorado sees it all. Composite decking’s weather resistance makes it a longer-lasting deck that looks great for years. 
  • Customizable: You can customize your composite deck by choosing from a wide range of textures and colors.


The Rocky Mountains are renowned for their breathtaking beauty, and our team of skilled contractors knows how to construct custom decks that complement Colorado’s stunning landscape while withstanding the region’s unique weather patterns.

How do we achieve this? As experienced deck builders in Longmont, Colorado, we employ high-quality pressure-treated LVL or steel for the deck’s frame, maximizing its structural integrity and resilience. Additionally, we utilize 12-inch spacing for center joints instead of the standard 16 inches, creating an even stronger foundation.

Plus, we get the best composite decking materials possible by offering decks from reputable companies like TrexTimberTech, and Deckorators. With all of these, plus an industry-leading two-year labor warranty on every installation, you can be confident that we’ll deliver your dream deck and that it will last as long as possible!


Creating a top-quality deck takes time, which is why effective communication is crucial when selecting a decking professional in Colorado. Few things are more frustrating than working with a deck contractor that fails to keep you informed about their progress.

At O’Keefe Built, we offer the “Once-a-Week Promise” to demonstrate our dedication to communication and customer satisfaction. As part of this promise, we reach out to you every week throughout the project, ensuring you’re always up-to-date on the status and timeline of your deck. We’re also available to address any questions or concerns you may have.

Furthermore, we provide a comprehensive two-year labor warranty for all our installations. If any issues arise with your deck within that two-year period, you can rely on us to resolve them promptly and at no additional cost to you.
