 Trustindex verifies that the original source of the review is Google. Colorado Custom Covers & Decks exceeded every expectation we had. We needed to replace our original wood deck at our home in the Ken Caryl Valley area and from the very first conversation to the final walkthrough, their communication was outstanding. They kept us informed throughout the entire process, answered every question promptly, and made sure we knew exactly what to expect every step of the way.

The quality of their workmanship is exceptional.   Nothing was overlooked, and
everyone on the crew was professional, friendly, and respectful of our home. They showed up when they said they would, kept the work area clean, and made the whole process much less stressful than we expected.

Our new deck is beautiful, sturdy, and exactly what we envisioned. I highly recommend Colorado Custom Covers & Decks. We couldn’t be happier with the finished product and would chose them again without hesitation!

 Trustindex verifies that the original source of the review is Google. We worked with Colorado Custom Covers and Decks to design and build an outdoor space we could use year round. They walked with us through every step of the process from permitting with Douglas County to the HOA approval to building and delivering a truly one of a kind outdoor space. We live in a new construction subdivision in Littleton, and finding a builder who could design a covered deck to match the look and feel of our new home was critical for what we wanted to achieve. Jonathan and his team made our vision a reality - we love our new outdoor space.

Frequently Asked Questions

What is an underdeck ceiling and how does it work?

An underdeck ceiling is a waterproof barrier installed beneath your deck boards that captures and diverts water away from the space below. Systems like Trex RainEscape use specially designed panels that attach to the joists, creating a sealed ceiling that channels moisture to gutters or designated drainage areas, keeping the underneath space completely dry.

How long does underdeck installation take?

Underdeck installation typically depends on deck size, system complexity, and whether additional features like lighting or electrical work are included. Our team works efficiently to minimize disruption while ensuring proper installation of all components.

Can underdecking be added to existing decks?

Yes, underdecking can be retrofitted to most existing elevated decks in Morrison, Colorado. Our team evaluates your current deck structure to ensure it can support the additional system and makes any necessary reinforcements during installation.
