Custom Window Installation in Colorado
With over years of serving Colorado homeowners, we custom-craft each window to tackle Colorado’s brisk winters, sun-scorched summers, and surprise hailstorms.
On this page, you’ll find the why, how, and where of our bespoke custom window installation process
Why Custom Windows Matter in Colorado
Colorado’s weather doesn’t hold still; sunny one moment, snowy the next. That’s why we design custom windows that flex with our unpredictable climate. By choosing precision-fit frames and high-performance Low-E glass, you’ll keep drafts at bay when the Rockies’ chill settles in and block 95% of harsh UV rays that can fade your furnishings.
And because no two Colorado homes are alike, from turn-of-the-century bungalows in Capitol Hill to sleek new builds near Boulder, we tailor window shapes and sizes to showcase your view, seal tight against hail, and give your place a facelift that’s anything but cookie-cutter.
Our Custom Window Options
When it comes to style, we don’t believe in one-size-fits-all. That’s why we offer everything from classic casement and picture windows to eye-catching geometric and bay configurations; each milled just for your home. Pick from sturdy vinyl, warm wood, durable fiberglass, or low-maintenance composite frames, then top it off with double- or triple-pane glass featuring Low-E or argon fills.
Building Codes & Permits in Colorado
Navigating Denver’s permit maze can feel like wrestling a mountain goat, but don’t sweat it. Whenever your project alters a structural opening, a permit is in order. We’ll handle all the paperwork, from Denver’s Quick Permits to Arapahoe County approvals, so you’re never left hanging.
Rest easy knowing we keep a finger on the pulse of local building codes, whether it’s minimum glass area for emergency exits or maximum U-factor requirements, making sure your new windows pass inspection on the first swing of the hammer.
Step-by-Step Installation Process
Consultation & Design Review
We kick things off with an on-site walkthrough, listening to your must-haves and sketching out window styles that match your home’s character.
Precise Measurements
Our team templates each opening, measuring width and height in three spots, to nail the final fit and avoid drafts or shim gaps.
Professional Installation
Country Construction LLC's top crews install your windows with industry-best techniques: weather-tight flashing, high-performance sealants, and careful leveling.
Maintenance & Care Tips
Keep your new windows happy and humming with a few simple rituals: each spring, inspect seals for cracks and clear debris from weep holes. Come fall, give moving parts a drop of silicone lubricant so sashes glide like butter.
Wash frames and glass with mild soap and a soft cloth; skip harsh chemicals and high-pressure sprays that can nick seals. Every five to seven years, freshen up the exterior caulk to lock out drafts. And if you’d rather leave it to us, ask about our annual inspection service for year-round peace of mind.
Homeowner Measurement & Design Guide
We want to empower you to get a head start, so here’s how to measure like a pro. Grab a metal tape and note both the rough opening (the framed space before trim) and the finished opening (after casing). Measure width and height in three spots: top, middle, bottom, and left, center, right—then record the smallest dimensions to avoid a too-tight fit.
For design, think about your home’s DNA: a Craftsman bungalow sings with divided-light grilles, while a modern build begs for clean, uninterrupted picture windows. Consider frame color too; darker hues pop against light siding, whereas white blends in for that “built-in” look.
