The windows in my Sandy Hill duplex are 80 years old - can I even get replacements that fit?

Yes, you can absolutely get replacement windows for your 80-year-old Sandy Hill duplex. While the original openings may have non-standard dimensions, modern window manufacturers offer custom sizing to fit virtually any existing opening.

Custom sizing is the standard solution for heritage and older homes in Ottawa's established neighborhoods like Sandy Hill. Window manufacturers measure your existing rough openings and fabricate windows to fit precisely, eliminating the need for major structural modifications. This approach preserves the character of your heritage duplex while dramatically improving energy efficiency and functionality.

Sandy Hill's housing stock from the 1940s typically features wood-framed windows that may have settled or shifted over the decades. A professional installer will measure each opening individually, as dimensions often vary even within the same house. The replacement process usually involves removing the old window and frame, then installing a new window system that fits the existing rough opening.

For an 80-year-old duplex, you're likely looking at significant energy savings with modern replacement windows. Original single-pane windows from that era have virtually no insulation value compared to today's triple-pane, Low-E coated windows with argon fill. In Ottawa's climate, this upgrade could reduce your heating costs by 15-25% while eliminating drafts and condensation issues.

The key is working with experienced installers who understand heritage properties and can navigate any unique challenges your duplex presents. Some windows may require minor trim work or insulation upgrades, but structural changes are rarely necessary for straight replacements.
