Colorado Window Installation Done Right —
The First Time
Old windows cost you money every single month. They leak warm air in winter, let heat in during summer, and make every room next to an exterior wall less comfortable than it should be. In Colorado, where winters are real and the sun at altitude is intense, the gap between a good window and a bad one shows up in your utility bill every month of the year.
Golden Bee installs and replaces windows across Colorado using premium brands — Simonton, Lansing, Ply Gem, Custom Window Systems, and Windsor — with honest estimates, professional installation, and a crew that works cleanly and respects your home throughout the process.

Window Replacement
If your windows are fogging between the panes, sticking, letting in drafts, or simply past their useful life, replacement is the right call. We measure precisely, order the right product, and install it properly so it performs the way it should from day one.
New Construction Installation
Building or adding to a home in Colorado? We work with builders and homeowners on new construction window installation — coordinating with your timeline, installing to spec, and making sure every window is sealed, squared, and performing before we leave.
Energy-Efficient Upgrades
Colorado’s altitude means higher UV exposure and more dramatic temperature swings than most of the country. Energy Star rated windows with Low-E glass and gas fill make a real, measurable difference in comfort and in what you pay to heat and cool your home every month.
Commercial Windows
We work on commercial properties as well as residential. Offices, retail spaces, multi-unit buildings — same honest estimates, same quality installation, spec’d correctly for the application and compliant with local code.
A Window Contractor Colorado Homeowners Can Count On
Window installation sounds straightforward. It is not always. An improperly installed window — one that’s not perfectly level, not properly flashed, or sealed with the wrong product — will leak air, let in moisture, and fail long before it should.
At Golden Bee, every window installation starts with precise measurements, uses manufacturer-recommended installation methods, and ends with a full inspection to make sure the window is operating correctly, sealed completely, and performing the way it was designed to.
- Honest, itemized estimates — no vague ballpark numbers
- Precise measuring and manufacturer-spec installation — on every window installation
- Full 3-part cleanup process on every job
- LIFETIME workmanship warranty
- We work with all major insurance companies

Window Questions We Hear All the Time
How do I know if my windows need to be replaced?
The most obvious sign is fogging or condensation between the panes — which means the seal has failed. Other signs include drafts around the frame, windows that stick or won’t lock, and noticeably higher heating or cooling bills. Windows over 20 years old are likely costing you money every month even if they look fine.
What window brands do you install?
Yes - this is one of our specialties. We document all damage, work directly with your insurance adjuster, and advocate to make sure your claim covers what it should. You do not have to navigate the process alone.
Are energy-efficient windows worth it in Colorado?
Yes — more so than in most states. Colorado’s altitude means more UV exposure, and the temperature swings are significant. Energy Star rated windows with Low-E glass and gas fill reduce heat transfer in both directions. Most homeowners see a noticeable reduction in utility bills within the first year.
How long does a window replacement take?
A single window typically takes one to two hours to replace. A full-house replacement usually takes one to three days depending on the number of windows and any framing work needed. We give you a clear timeline before we start.
Do you work on commercial window projects?
Yes. We handle commercial window installation and replacement across Colorado — offices, retail spaces, and multi-unit buildings. Commercial projects often involve different sizing, glazing requirements, and code compliance. We assess each project individually.
What other services does Golden Bee offer besides windows?
We provide a LIFETIME workmanship warranty on every installation, plus the manufacturer warranty on all materials. We walk you through the full coverage at the end of every job.
