Exterior Renovations in Denver & the Front Range
OUTDOOR LIVING SPACES, DECKS, AND THE EXTERIOR WORK THAT TIES IT ALL TOGETHER
Outdoor Living, Built for Colorado
Most of our exterior renovations are outdoor living projects. Outdoor kitchens, sport courts, sunrooms, decks, and patios. We design and build the space itself, plus the siding, windows, and exterior work that connects it back to the rest of the house.
Whether you're adding one space or rethinking the entire exterior, we use materials that handle Colorado weather and detail the finish work to match the existing architecture.
Our Approach to Exterior Projects
We start with how you want to use the space. What's not working now, what you wish you had, and how you want it to feel day to day. From there, we build a scope of work that matches your goals and timeline. The next step is creating a retreat in your own backyard.
During the build, your Project Manager owns daily updates, subcontractor coordination, and any decisions that come up along the way. You'll know what's happening on your house every day it's happening.
Frequently Asked Questions About Exterior Renovations
Curious about what to expect? Here are answers to some of the most common questions homeowners ask about exterior renovations.
- What is included in an exterior renovation?expand_more
- Outdoor kitchens, sunrooms, sport courts, decks, patios, and pergolas make up most of our exterior projects. We also handle siding, windows, doors, trim, and full exterior rebuilds when they're part of the scope.
- How long does an exterior renovation take?expand_more
- It depends on the project. A new deck or sunroom might run a few weeks. An outdoor kitchen with a sport court and a refresh of the siding and windows can run several months.
- Can you match the new exterior to the existing home?expand_more
- Yes. When we build a sunroom or add an outdoor kitchen, we design the materials and details to match what's already on the house.
- Do exterior renovations improve home value?expand_more
- Yes. Outdoor living is one of the higher-return exterior investments in Colorado, and updated siding and windows add resale value and energy efficiency.
