Portage Ave double-hung window installation — measured, sealed, warrantied

Double-hung windows have two sashes that slide vertically and tilt in for easy cleaning — a timeless, versatile style that suits nearly any Portage Ave home.

Every opening measured on-site

Full air-seal on every unit

Written frame + sealed-glass warranty

Classic looks, modern seals

The double-hung is the classic North American window — two sashes stacked in one frame — and its big modern advantage is that both sashes tilt inward, so you can wash the outside glass while standing safely inside. On a second storey or over a porch roof, that alone is worth it. Under the traditional looks sit modern compression and bulb weatherstripping and, with triple-pane glass, a genuinely tight, efficient window.

It is the natural match for traditional and character and heritage homes, where the tall, symmetrical proportions keep the streetscape right — but you can have them in low-maintenance vinyl or fiberglass so the period look does not come with period upkeep.

Both sashes operate, so you can open the top, the bottom or both to set the airflow you want — drop the top sash to let warm air out near the ceiling while keeping the lower opening secure.

Versatile, easy to live with

Open the top, the bottom or both for balanced ventilation, and tilt either sash in for cleaning without a ladder. The spring or block-and-tackle balances hold the sash exactly where you set it, and the sashes lock into a tight seal when closed — no rattling in a hard wind.

Every unit is measured on site, air-sealed by our own crews with backer rod and low-expansion foam, and listed line by line in a written quote with its glass package and U-factor, all backed by a written frame-and-glass warranty.

Double-Hung Window Installation questions answered

Cleaning, efficiency and older-home fit for double-hung windows.

Can I clean double-hung windows from inside?

Yes — both sashes tilt inward, so you can wash the exterior glass from inside the room without a ladder or an outside trip. That is a genuine safety and convenience win on upper floors, over a deck, or above landscaping where setting a ladder is awkward. The tilt latches are simple to operate, and the sashes drop back into their tracks and re-seal in seconds. It is one of the main reasons homeowners still choose double-hung over a fixed or out-swing style.

Are double-hung windows energy-efficient?

With modern weatherstripping and triple-pane Low-E glass, yes — a quality double-hung seals far better than the drafty old ones it replaces and performs very well in a Portage Ave winter. A casement still seals a touch tighter because it clamps shut by compression, so if squeezing out every last bit of efficiency on an exposed wall is the priority, we may suggest a casement there. For most rooms, a triple-pane double-hung is both efficient and true to the look of the house.

Do they suit older homes?

Perfectly — the double-hung is the classic style for traditional, character and heritage homes, and its tall, even proportions keep an older streetscape looking right. We can match the sightlines, grille patterns and colours of your existing windows so a partial replacement blends in, or do the whole house in one consistent look. And because you can have that heritage appearance in vinyl or fiberglass, you keep the character without signing up for scraping and repainting every few years.

Can I get grilles or divided-light styling?

Yes — double-hung windows take colonial grilles and other patterns beautifully, which is why they suit traditional and heritage homes so well.

Do both sashes lock securely?

Yes — the sash lock pulls the two sashes tight together and into the frame, sealing the meeting rail and adding security when closed.

Our character home needed windows that looked right, and the double-hungs match the original style perfectly while sealing like new.

W. Fontaine

Homeowner, Portage Ave

Being able to tilt both sashes in and clean them from inside is a game on our second floor. Wish we had done it years ago.

K. Bergen

Classic look, modern seals — exactly what they promised. The crew matched the grille pattern to our existing windows.
