My Barrhaven home is only 10 years old but the windows are failing - is this normal?

Unfortunately, yes - window failures in 10-year-old homes are more common than they should be, especially in Ottawa's harsh climate. Many builders use minimum-grade windows to keep costs down, and these often start showing problems within 5-15 years.

The most common failures you're likely seeing include seal failures in double-pane glass (causing fogging between panes), hardware problems like handles breaking or windows not staying open, weatherstripping deterioration leading to drafts, and frame warping or cracking from Ottawa's extreme temperature swings. In Barrhaven specifically, many homes from that era used vinyl windows with welded corners that can separate over time.

Ottawa's climate is particularly tough on windows - we see temperature swings from -30°C to +35°C, plus significant humidity changes throughout the year. Windows that might last 20 years in milder climates often fail much sooner here. The thermal expansion and contraction, combined with ice buildup and UV exposure, puts tremendous stress on seals and frames.

Builder-grade windows typically use thinner glass, basic weatherstripping, and lower-quality hardware compared to replacement windows. They're designed to meet minimum building code requirements and pass initial inspections, not necessarily to last decades in our climate. Many use single-seal glass units instead of dual-seal, making them more prone to moisture infiltration.

The good news is that modern replacement windows are significantly better than what was commonly installed 10 years ago. Today's quality windows feature triple-pane glass, advanced Low-E coatings, superior weatherstripping, and much better hardware. You'll likely see dramatic improvements in energy efficiency, comfort, and durability.
