The most popular choice for Colorado homes. Sliding doors give you an unobstructed view of the backyard and operate on a track with no swing clearance required on either side, which is a real advantage on tighter decks and patios. They work well on both contemporary and traditional homes, and the Simonton sliding doors we install carry the AAMA Gold Label certification — the industry benchmark for weather resistance, air infiltration, and structural performance. In Denver, where a morning can start at 20 degrees and hit 60 by early afternoon, that kind of certification isn’t just marketing language.
French doors bring a classic look that suits traditional and transitional home styles well. Both panels open outward or inward depending on your layout, so you’ll need clearance room, but the payoff is a wider opening and a more architectural feel. Simonton’s French rail collection is one of our most-requested options for homeowners doing a full exterior refresh.
Colorado is harder on exterior materials than most people realize. Intense UV exposure at altitude, freeze-thaw cycles through fall and spring, and wide daily temperature swings all add up — and the wrong door material will show its age well before it should. ENERGY STAR sets the performance standards for doors in the Northern climate zone that Colorado falls under, and every door we recommend meets or exceeds those requirements.
Vinyl is Gravina’s most-installed patio door material because it holds up well against Colorado’s sun and temperature swings without rusting, rotting, or needing repainting. Modern reinforced vinyl is far stronger than what was available 20 years ago and handles the altitude UV load better than most homeowners expect. Fiberglass expands and contracts less than vinyl over temperature changes and offers higher strength-to-weight performance, making it a strong option for larger openings or higher-end projects. Steel delivers the most security of any door material and outlasts wood by a significant margin — worth the conversation if the door faces west-facing afternoon sun or security is the main concern.
We’ve worked with a lot of manufacturers over 35-plus years and have narrowed our patio door offering to brands we stand behind. Our primary lines include Simonton, Pella, and Prime Window Systems, each offering different strengths in price point, style range, and performance specs. When we come out for your consultation, we’ll walk you through what makes sense for your specific opening and budget — not just whatever is easiest to install.
Gravina’s® has been based in Denver since 1988, with showrooms at 950 W Evans Ave in Denver and in Littleton, and more than 100,000 projects completed across the metro and Front Range. Patio doors are one of the most common reasons homeowners call us for the first time, and one of the places where installation quality matters most.
We use our own installation crews on every job, not subcontractors, and every installer is familiar with what Colorado exterior work actually demands — proper sealing against wind-driven rain, correct flashing around the frame, and making sure the door operates smoothly through the temperature swings that stress frames every season. A patio door installed poorly will bind in summer and draft in winter, and in our experience that’s almost always an installation issue rather than a product one. The consultation is free and pressure-free — we measure, walk through your options, and give you a real quote, and you decide from there.
We serve the full Denver metro and Front Range, including Littleton, Englewood, Aurora, Centennial, Highlands Ranch, Lakewood, Westminster, Arvada, Thornton, and Fort Collins. If you’re also looking at replacing windows while the project is open, our team works on the same schedule and many homeowners bundle both to get it done in a single visit.
If your patio door isn’t working the way it should, or you want to get it handled before fall, call or text (303) 472-8462 or schedule your free in-home consultation online. We’ll measure the opening, walk you through what fits your home and budget, and give you a clear, no-pressure quote.
