Typical Project Timeline

What is a double-hung window?

A double-hung window has two independently movable sashes. Both the top and bottom panels slide up and down independently. This seemingly simple design unlocks meaningful advantages in ventilation, cleaning, and child safety that other styles can’t match.

Two Independent Sashes

Open the top sash alone, the bottom alone, or both simultaneously. More ventilation control than single-hung or sliding windows.

Tilt-In Cleaning

Both sashes pivot inward so you clean exterior glass surfaces from inside. A major practical advantage for two-story Colorado homes.

Top-Vent Airflow

Open only the top sash to let hot air escape while keeping the lower sash closed. Ideal for households with children, pets, or ground-floor security concerns.

Works in Almost Any Home

Compatible with colonial, craftsman, ranch, Victorian, mid-century, and contemporary architecture. The most versatile window style made.

Easy Replacement

The rectangular frame and standard sash sizing makes double-hung windows the most straightforward window to replace with lower labor cost and faster installation.

How Double-Hung Window replacement works

From your first call to final walkthrough, here’s exactly what to expect. Most Denver metro projects are complete in one to two days with no overnight openings.

Free In-Home Estimate

We measure every opening, assess framing condition, and show you products in-person. No pressure, transparent pricing provided before you commit.

Step 2

Custom Order & Permit

Windows are factory-ordered to your exact rough opening sizes. We file all permits with Denver, Aurora, Littleton, or Golden on your behalf.

Step 3

Professional Installation

Crew arrives on schedule. Old windows removed, openings inspected and flashed, new units installed, insulated, and sealed to manufacturer spec.

Step 4

Interior & Exterior Trim

Interior trim reinstalled or replaced. Exterior caulked and finished. Every window tested for smooth operation, weathertight seal, and proper locking.

Step 5

Final Walkthrough

We walk every window with you, demonstrate tilt-clean function, explain warranty coverage, and handle all debris removal before we leave.

Why Colorado’s Climate changes everything

A double-hung window specified for coastal California will fail prematurely in Denver. The Front Range’s altitude, UV intensity, thermal cycling, and hail risk require specific materials, glass packages, and frame specs.

High-Altitude UV Exposure

Denver sits at 5,280 ft. Each 1,000 ft of elevation increases UV radiation by roughly 4%. That means 20–25% more UV than sea level — fading frames, degrading seals, and cooking interior furnishings. Specify Low-E coatings that block UV without noticeably reducing natural light.

Freeze-Thaw Condensation Risk

Colorado’s dry air lulls homeowners into thinking condensation isn’t a problem, then a temperature plunge hits. Condensation between panes is a sign of failed seals; condensation on interior surfaces means insufficient insulating value. For Golden, Evergreen, and foothill locations, triple-pane glass adds meaningful protection.

High-Altitude Wind Loads

Front Range Chinook winds can push 100+ mph gusts in foothills locations. Double-hung windows should meet or exceed AAMA/WDMA performance ratings for the applicable wind zone. In Golden and mountain-adjacent neighborhoods, we specify reinforced sash hardware and multi-point locking systems.

Extreme Thermal Cycling

Front Range homes routinely see 40–60°F swings in a single day. This thermal cycling expands and contracts frames constantly — low-quality vinyl or poorly installed windows will rack, seal, and stick. Fiberglass expands at nearly the same rate as glass, making it the most dimensionally stable frame material for Colorado.

Hailstorms

Colorado ranks in the top 3 states nationally for hail damage claims. While standard double-pane glass handles moderate hail, neighborhoods in Aurora and the eastern Denver metro with frequent severe storms benefit from laminated impact-resistant glass — it won’t shatter into shards even when cracked.

Low Humidity & Dryness

Denver averages 15–20% relative humidity in winter — one of the driest major cities in the US. Wood frames shrink and crack in this environment. If you want wood interiors, specify aluminum or fiberglass exterior cladding to protect the wood from Colorado’s drying effects while preserving interior aesthetics.
