Planning Your Project
What to Look at Before Replacing Windows or Doors
A good replacement project starts with the existing opening and the problem you want to solve. Drafts, difficult operation, damaged frames, limited ventilation or an outdated entrance can all point to different product choices.
- Condition and dimensions of the existing opening
- Desired ventilation and natural-light levels
- Exterior clearance for operating windows or doors
- Glass, colour, hardware and finishing preferences
- Installation details needed for a weather-tight fit
