When most homeowners think about replacing their windows, the first thing they consider is the product: triple-pane vs. double-pane, vinyl vs. wood, or energy ratings and styles. While these are all important, there’s one factor that often gets overlooked—and yet it can make or break the entire investment:

Proper installation.
At Tricity Windows and Doors, we’ve seen it all—premium windows that fail after just a few years because of poor installation, and standard windows that perform beautifully for decades thanks to skilled workmanship. That’s why we only use in-house professional installers—because your window is only as good as the way it's installed.
Why Installation Is So Critical
Even the most advanced, energy-efficient window will underperform if it’s not installed correctly.
Here’s why proper installation matters:
1. Energy Efficiency Depends on a Tight Seal
Poor installation often leads to gaps between the window frame and your home’s wall, letting in drafts and moisture. This compromises insulation and can cause your heating and cooling bills to skyrocket.
2. Improper Installation Voids Manufacturer Warranties
Most window manufacturers clearly state that their warranty is only valid if the product is installed according to their specifications. One wrong step-and you could lose your coverage.
3. Moisture and Mold Risk
Incorrect shimming, lack of flashing, or misaligned frames can allow water to seep into the wall. Over time, this can lead to rot, mold, and expensive repairs that go far beyond the window itself.
4. Aesthetic and Functional Issues
A poorly installed window might stick, be difficult to open, or just not sit right. Good installers make sure the unit is square, level, and fully functional-because details matter.
