Window Replacement in Dillon, CO: Built for Altitude, Installed for Peace of Mind

In Dillon, CO — where alpine beauty meets year-round exposure — your windows must be more than decorative. At over 9,000 feet in elevation, your home needs window systems that can handle harsh winters, intense sun, and wind-driven snow — without compromising your view.


At Five Seasons Windows and Doors, we install high-performance, brand-selected window and door systems specifically rated for mountain conditions. Whether you're upgrading a ski retreat in Dillon Valley or modernizing a lakeside property near the Dillon Reservoir, we bring precision, durability, and trusted expertise to every project.

Engineered for Mountain Homes, Condos, and Cabins

Dillon’s housing stock includes everything from vacation homes and condos to year-round mountain cabins. Many properties are exposed, multi-level, or governed by HOA design guidelines. We help you choose from top national brands that combine aesthetic flexibility with rugged performance — so your new windows fit both your home and its environment.

We install:


  • Casement, double-hung, and picture windows for insulation and light

  • Sliding or French-style patio doors for decks and walkouts

  • Bay, bow, or fixed windows with mountain views in mind

  • Impact-rated options for homes vulnerable to heavy storms or wind

Our certified, background-checked installers follow manufacturer-approved methods to ensure a tight, durable fit — especially important in Dillon’s freeze-thaw cycles.

Performance You Can Rely on at 9,000+ Feet

Living at high elevation means managing extreme and often unpredictable weather. That’s why we start with a free thermal inspection to identify where your home may be leaking energy — and how modern window technology can help.

Our preferred systems feature:


  • Low-E coated, multi-pane glass to block UV and trap heat during cold months

  • Argon- or krypton-filled units to reduce condensation and drafts

  • Composite or fiberglass frames that resist expansion, contraction, and seal failure

  • Glazing options designed for snow load and solar reflection

We’ll recommend the right frame and glass combinations based on your home’s position, sun exposure, and heating needs — whether you live near Tenderfoot Street or high on the hill near Summit Cove.
