Portage Ave storm window replacement — done right for our winters

Storm windows add an extra barrier against Portage Ave cold and wind. We add or replace exterior and interior storm windows to boost comfort on older or heritage windows.

Every opening measured on-site

Full air-seal on every unit

Written frame + sealed-glass warranty

An extra winter barrier

A storm window adds a second layer of glass — and, more importantly, an insulating air gap — in front of or behind your existing window, cutting drafts and heat loss for a fraction of the cost of full replacement. On character and heritage homes where you want to keep the original wood windows for their look, it is a smart, budget-friendly way to boost comfort without changing the appearance of the house.

The air gap is what does the work: it slows heat moving through the assembly and takes the edge off the cold-glass draft from a single-pane original.

It is a practical alternative to replacement in some cases — but not all — and part of our job is telling you honestly which situation you are in.

Comfort without a full replacement

A storm window only helps if it actually seals, so we fit ours tightly to the opening rather than leaving the gaps that make cheap storms useless. Where the primary windows are still sound, that tight fit delivers real comfort gains for modest money.

And where the primary windows are failing — rotted, drafty, fogged — we will tell you plainly that a full replacement is the better long-term value rather than sell you a storm over a dying window. Written quote, clean install, honest advice either way.

Storm Window Replacement questions answered

Winter performance, storm-versus-replacement and interior or exterior.

Do storm windows really help in Portage Ave?

Yes — the extra pane and, above all, the trapped air gap between the storm and the primary window reduce drafts and heat loss, and the effect is biggest on older single-pane windows that have no insulating value of their own. You will feel less cold radiating off the glass and less draft near the window. A storm will not match the performance of a modern triple-pane unit, but as an add-on to windows you want to keep, it is a real, cost-effective improvement for a Portage Ave winter.

Storm windows or full replacement?

It depends on the condition of your existing windows. Storm windows are a lower-cost boost for primary windows that are still sound and that you want to keep — often original wood windows on a character home. If the primary windows are rotted, drafty, painted shut or fogged, a full replacement almost always pays back more in comfort, efficiency and maintenance, and a storm over a failing window just postpones the inevitable. We look at what you have and give you the honest comparison, including both numbers, so you can choose.

Interior or exterior storm windows?

Both work, and the right choice depends on your windows, the look you want and your budget. Exterior storms mount outside and protect the primary window from the weather, but have to shed water and be accessible to install; interior storms mount inside, are easier to fit and remove seasonally, and keep the exterior appearance untouched — often preferred on heritage facades. Either way, a tight seal is what makes them effective. We recommend the option that fits your windows and finish, and install it to actually seal.

Will storm windows change the look of my house?

Interior storms leave the exterior untouched, and exterior storms can be colour-matched, so on a heritage home the original look is preserved.

Do storm windows need much maintenance?

Very little — an occasional clean and a check of the seal is all a well-fitted storm window needs to keep doing its job.

★★★★★

Wanted to keep our original wood windows so they fitted tight storm windows instead. Noticeably warmer for a fraction of the cost.

H. Ducharme

Homeowner, Portage Ave

Honest that a storm window made sense on our heritage windows rather than replacing them. Snug fit, real difference.

A. Nijjar

Cut the draft on our old front windows without changing the look of the house. Exactly what we wanted.

R. Comeau

★★★★

Fitted properly so they actually seal, unlike the loose ones we had. Cozy improvement for the money.
