Brick to Brick vs Retrofit

It's no secret that high-quality, energy-efficient windows offer a lot of potential benefits and savings to homeowners. But it might not always be clear whether to go with a full replacement or a retrofit.

First, a distinction: a full replacement means the entire window frame and sash are removed. A retrofit, on the other hand, means only the window sash is removed — the frame and trim remain in place, making it less expensive and less labour-intensive than a full replacement.

When a Full Window Replacement Makes Sense

Problems with the existing frame

One of the most common reasons homeowners choose a full window replacement is a problem with their existing frame. In some cases, particularly with wood, rot will have set in, compromising the frame's structural integrity and the health of the home's occupants.

Rot is often caused by moisture, which in turn can lead to mould growth and further problems. Over time, mould can spread beyond the frame to the home's wall. A rotting or irreparably damaged window frame should be replaced.

Wanting a significant increase in energy efficiency

If you've put off replacing your windows for a long time, you could be missing out on energy savings, improved home comfort, and other benefits of new windows. At GreenOn Homes we've made significant investments in state-of-the-art equipment to offer some of the most advanced products on the market. We fusion-weld the corners of our window frames for a superior seal — one that's airtight and weathertight.

For a product to be ENERGY STAR certified today, it has to meet strict standards and pass independent tests. We've engineered our vinyl windows to not only meet, but exceed, ENERGY STAR compliance.

Style upgrades

A full window replacement also gives you the chance to update your exterior and interior trim. For the ultimate in design versatility, we offer a variety of trim options, corner blocks, and PVC jamb extensions in your choice of colour.

When a Window Retrofit Makes Sense

Existing frame and trim are in good condition

Sometimes called an insert or sash-only replacement, a window retrofit can deliver real improvements in comfort and energy efficiency without the cost or hassle of a full replacement. This economical option makes sense if your existing window frames are still in good shape and were properly installed — retrofit windows let you keep your current exterior and interior trim, since it's left intact during installation.

Older homes with high-quality wood-framed windows are also good retrofit candidates, since the process won't disrupt the house's traditional charm.

Interested in replacing the glass only

Advancements in window glass technology have led to more choices than ever, including low-emissivity (Low-E) glass and warm-edge spacers. Upgrading to Low-E glass with triple glazing and warm-edge technology can dramatically improve comfort and energy efficiency without a major renovation. If the glass in your windows is clear, damaged, or single-pane, a retrofit offers a sensible, cost-effective way to upgrade.
