At Reliable Glass and Windows Ltd., we offer professional window replacement and installation services in Calgary, providing homeowners with energy-efficient, durable, and beautifully installed windows that enhance comfort, reduce utility bills, and improve property value.
With over 35 years of experience, our team handles full-frame window replacements—removing outdated, inefficient, or damaged windows and replacing them with locally engineered, Energy Star-compliant units.
Why Choose
Full Window Replacement?
Many older homes in Calgary have aging window frames that no longer seal properly or are showing signs of wear. If your windows are drafty, rotten, cracked, or outdated, replacing the entire window unit—glass and frame—is the best long-term solution.
Benefits of Full Window Replacement:
- Improved insulation and energy efficiency
- Elimination of drafts, condensation, and rot
- Updated style and curb appeal
- Enhanced resale value
- Reduced noise from outdoors
- Long-lasting performance with high-quality framing materials

LowE Argon Glass
For Maximum Performance
Every full window replacement includes the option to upgrade to LowE Argon Insulated Glass—a high-efficiency glass that works with your new frames to maximize performance in Calgary’s extreme weather.
Why LowE Argon Glass Matters:
- Reflects indoor heat back in during winter
- Blocks solar heat and UV rays in summer
- Reduces energy use and utility bills
- Protects interiors from sun damage
- Improves indoor comfort all year long
Combined with new window frames, this upgrade significantly enhances your home’s R-value and makes your space quieter, cozier, and more efficient.
Just Want to Replace the Glass?
If your window frames are still in great shape and you’re only dealing with foggy, broken, or inefficient glass, you may not need full window replacement.
