Portage Ave energy-efficient window replacement — done right for our winters

ENERGY STAR® triple-pane windows with Low-E coatings and argon fill cut heat loss, stop the cold-glass draft and reduce condensation — the upgrade Portage Ave homeowners feel first.

Every opening measured on-site

Full air-seal on every unit

Written frame + sealed-glass warranty

Warmth you feel and see

Triple-pane glass with Low-E coatings and argon fill dramatically reduces the heat your windows leak all winter — three panes and two low-emissivity layers reflect warmth back into the room while the sealed argon gaps slow conduction. Most Portage Ave homeowners feel the difference the first real cold snap: no more cold-glass draft pooling by the couch, no frost creeping up the pane, and a furnace that cycles less.

You see it on the bill by spring, and you feel it every day in between — warmer rooms, warmer glass to sit beside, and far less condensation on the coldest mornings.

Ask about ENERGY STAR® models, which are built to a verified performance standard for our climate zone and may qualify for manufacturer or efficiency rebates — we identify the eligible options and handle the paperwork.

Install, cleanly

Lower bills, quieter rooms

Efficient glass does more than save heat: the same mass and multiple panes that block heat loss also cut outside noise, so a busy street or back lane gets noticeably quieter, and the warm interior surface sharply reduces the condensation that soaks sills and grows mould on old windows.

We size the glass package to each elevation so you get the performance where it counts, file the rebate paperwork for qualifying upgrades, and register a written frame-and-glass warranty in your name.

Energy-Efficient Replacement questions answered

Triple-pane value, rebates and real heating savings.

Is triple-pane worth it in Portage Ave?

For most Portage Ave homes, yes. Triple-pane Low-E glass with argon noticeably cuts the cold-glass draft, lowers heat loss and reduces the condensation that forms on the coldest mornings — the difference is biggest on north- and west-facing walls that take the wind and in rooms where you sit near the glass. It is not automatically right for every single opening, so at the estimate we show you the U-factor gain and the price gap side by side and let you decide room by room, rather than selling one spec across the whole house.

Do efficient windows qualify for rebates?

Many ENERGY STAR® windows qualify for manufacturer promotions or efficiency-program rebates, and the specific programs and amounts change from year to year. We keep track of what is current, identify which of your chosen units and glass packages are eligible, and file the paperwork for you so you actually capture the savings instead of leaving them on the table. We will lay out any available rebates in the written quote so you can see the net cost, not just the sticker price.

How much can I save on heating?

Savings vary by home — it depends on how leaky your current windows are, how many you replace, your home's heating system and how you keep it — so we will not promise a specific percentage. What is consistent is that swapping old, single- or drafty double-pane windows for triple-pane glass makes a clear, felt difference on Portage Ave winter bills and comfort. The biggest gains come from replacing the worst offenders first: the drafty, frosted, north-and-west units. We can help you prioritize if you are phasing the work.

How do I compare window efficiency?

Look at the U-factor — the lower the number, the less heat it loses. We show the U-factor for each glass package so you can compare like for like.

Which windows should I replace first?

Start with the worst offenders — the drafty, frosted, north- and west-facing units — for the biggest comfort and bill gain, then phase the rest.

Whole-home triple-pane and we felt the difference the first cold snap. The heating bill dropped noticeably by spring.

B. Lefebvre

Homeowner, Portage Ave

No more cold-glass draft by the sofa and way less condensation on cold mornings. They filed the rebate paperwork too.

K. Brar

Warmer rooms and a quieter house. They sized the glass to each wall instead of overselling us one spec everywhere.

S. Tremblay

The furnace cycles far less now. Honest advice on where triple-pane paid off and where it was not needed.
