Replacement Windows That Lower Your Energy Bills
Old single-pane windows are thieves. They leak heat in brutal Pacific Northwest winters and cool air in hot Spokane summers. Signature Exteriors installs premium double and triple-pane replacement windows engineered to reduce energy waste, improve comfort, and pay for themselves through lower utility bills.
Our Windows Services
Double-Pane Windows
Low-E coatings and argon gas fill reduce heat transfer. Perfect for moderate climates (Spokane, Coeur d'Alene).
Triple-Pane Windows
Maximum insulation for extreme climates. Ideal for high-altitude Oregon homes and cold Spokane winters.
Solar Control Coatings
Spokane-area customers benefit from reflective coatings that reject 50%+ of solar heat, keeping homes cooler and reducing AC load.
Professional Installation
Proper flashing, sealing, and framing prevent leaks and drafts. Bad installation ruins energy performance.

Frequently Asked Questions
How much will new windows reduce my energy bills?
Typically 10-20% reduction in heating/cooling costs, depending on your current windows, home size, and climate. Spokane-area homes see the biggest savings with solar control coatings.
Are replacement windows cheaper than double-pane upgrades?
Yes. Replacement windows use your existing frames, avoiding structural work. If frames are damaged, full-frame installation costs more but performs better.
Do I need triple-pane windows?
Triple-pane is best for extreme climates (high-altitude Oregon, cold Spokane). Double-pane is sufficient for most Idaho and Washington homes. Spokane-area homes benefit more from solar control than triple-pane.
Will new windows reduce outside noise?
Yes, especially triple-pane or laminated glass. The sealed air space and heavier glass absorb sound, creating quieter interiors.
What warranty do new windows carry?
Manufacturers typically warrant 10-20 years on glass, 5-10 years on hardware. Signature Exteriors provides 5-year workmanship warranty.
