At Ecoline, we provide both full-frame and retrofit window replacement. The best option depends on the condition of your current windows.
If you have an older home or want a full window upgrade, we usually suggest full-frame replacement. This lets our installers check the entire opening for hidden moisture, damaged insulation, air leaks, and other issues before installing your new window.
| Full-Frame Replacement | Retrofit Replacement | |
|---|---|---|
| What we remove | Window, existing frame and interior/exterior trim as required | Existing window unit while the original frame remains |
| Best for | Older or damaged frames, major efficiency upgrades and openings with possible hidden issues | Existing frames that are structurally sound and in good condition |
| Access to the opening | Full access to inspect insulation, sealing and surrounding conditions | Limited because the original frame stays in place |
| New window size | Makes better use of the original rough opening | New unit fits inside the existing frame, which can slightly reduce glass area |
| Installation scope | More extensive installation and finishing | Faster and less invasive |
| Typical cost | 15% higher because more material and labour are involved | Usually lower when the existing frame can safely be reused |
| Our recommendation | Preferred when we need to address the complete window opening | A practical option when the existing frame does not need replacement |

You might need new windows if you notice drafts, condensation between the panes, damaged frames, windows that are hard to open or close, higher energy bills, or if your home feels less comfortable due to heat loss.
Ecoline has a variety of replacement window styles, such as casement, awning, slider, picture, bay, bow, egress, and custom options.
Modern triple-pane replacement windows are up to 55% more energy efficient compared to old home. They use insulated frames, multi-pane glass, Low-E coatings, gas fills, and are installed properly to keep your home comfortable.
The cost of replacing windows depends on things like the size and style of the window, the type of glass, how the windows are installed, the condition of your frames, how many windows you need, and where your home is located.
Full-frame replacement is usually best if your current frames are damaged or if you want a full upgrade. Retrofit replacement works well when your existing frames are still in good shape.
Ecoline helps homeowners in many cities and provinces across Canada. Check your local service page to find information for your area.
How long it takes depends on how many windows you need, how complex the project is, and which products you choose. Most of the time, it takes up to 8 weeks to make, deliver, and install your new windows.
