Frequently Asked Questions — Window Replacement in Denver, CO
How much does window replacement cost?
Single-hung or double-hung windows run $300—$800 per window installed. Casement and specialty windows average $500—$1,500 each. A full-home window replacement (15—20 windows) typically costs $8,000—$20,000. Energy-efficient (ENERGY STAR) windows qualify for a 30% federal tax credit up to $600/year.
When should I replace my windows?
Replace windows when: frames are visibly rotted or warped, you feel drafts around closed windows, condensation forms inside the glass (seal failure), they're single-pane, or the home needs noise reduction. Modern double or triple-pane windows cut heat loss by 20—40%.
What is the most energy-efficient window option?
Triple-pane windows with low-E coating and argon gas fill are the most efficient. U-factor measures heat loss (lower is better — target = 0.25). Solar Heat Gain Coefficient (SHGC) measures solar heat entry (lower in hot climates, higher in cold). Look for ENERGY STAR Most Efficient certifications.
How long does window replacement take?
Most window replacement projects take 1—3 days for a full home of 15—20 windows. Each window takes 30—60 minutes to install. Structural work (like widening openings) adds time. Insert replacements (within existing frame) are faster; full-frame replacement is more thorough.
What is the best window material: vinyl, wood, or fiberglass?
Vinyl is the most popular — low maintenance, good insulation, affordable. Fiberglass is more expensive but stronger, more dimensionally stable, and better for extreme climates. Wood offers the best aesthetic and can be painted but requires more maintenance. Composite (wood-clad vinyl) is a popular split choice.
