It’s common for homeowners to ask, how often should windows be replaced? Most windows should be replaced every 15 to 30 years, depending on the material, installation quality, and how well they have been maintained. However, some may need replacing sooner if you notice issues like drafts, condensation, or rising energy bills.
In this blog, the experts at Glass Repair Canada will explain how long different window types typically last, the signs that it might be time for a replacement, and how energy efficiency plays a role. You’ll get the information you need to make the right decision for your home.
How Often Should Windows Be Replaced?
Most residential windows should be replaced every 15 to 30 years. The exact timing depends on several factors, including the type of material, the quality of installation, how well they’ve been maintained, and exposure to weather conditions. Some windows may last closer to 15 years in harsh climates, while well-maintained units in milder environments can last up to 30 years.
Routine care, such as cleaning the frames and checking for damaged seals, can help extend the lifespan of your windows. However, even well-maintained windows may start showing signs of wear earlier than expected.
Climate, sun exposure, and even the direction your windows face can affect durability. For example, windows that receive direct sunlight or are exposed to strong winds and heavy rain may deteriorate faster. If you’re unsure whether your windows are still performing properly, watch for common warning signs, which we’ll cover next.

New windows, on the other hand, bring real improvements you’ll notice every day. When thinking about how often to replace your windows, you may decide to do it sooner so you can enjoy these benefits right away:

How Often to Replace Windows for Energy Efficiency
Our experts suggest replacing windows every 15 to 20 years even if the frames still look fine. If maximizing the energy efficiency in your home is a larger priority however, you may want to replace your windows sooner. Older single-pane or poorly sealed units can cost you hundreds per year in heating and cooling. Signs of drafts, damaged frames, condensation between panes, and difficulty operating them indicate a decline in efficiency and a need for replacement with newer options.
Modern ENERGY STAR® windows are built with insulated glass and advanced frames, cutting down energy loss significantly. This upgrade can reduce your energy bills while making your home more comfortable year-round.
