Ask Us Anything About Windows & Doors

In Calgary's climate with temperature swings from -30°C to +30°C, triple-pane windows provide measurably better insulation (R-value typically 7-8 vs 5-6 for double-pane) and reduce condensation. For homes over 20 years old or with high heating bills, the energy savings often pay back the investment within 7-10 years.

Signs include:

• Visible condensation between panes
• Drafts around frames
• Difficulty opening or closing sashes
• Visible decay or damage to frames
• Noticeably higher heating bills
• Moisture on interior surfaces

If your windows are over 20 years old, even without obvious damage, it's worth getting a professional assessment.

Honest answer: Brand matters less than specs. What matters most is:

• U-value (lower is better for insulation)
• SHGC rating (solar heat gain coefficient)
• Weatherstripping quality
• Installation precision

A mid-range window properly installed outperforms a premium window installed poorly every time.

In Calgary, expect $300–600 per window installed (varies by size, style, and materials). A typical home replacement ranges $8,000–$25,000.

Yes. Check for:

• Clean caulk lines (not excessive)
• No gaps between frame and wall
• Level and plumb sashes
• Smooth operation
• No visible foam gaps
• Proper weatherstripping

Interior condensation is normal when humidity meets cold glass (it's moisture, not a seal failure). Exterior condensation is actually a sign windows are insulating well.

Persistent interior fogging between panes indicates a seal issue and should be addressed.
