## Sound Familiar?

Four things bring GTA homeowners to us. Here's what's actually going on behind each of them.

### Drafty Builder-Grade Windows

Cold air rolls along the floor and the furnace runs longer every winter.

Worn weatherstripping and racked sashes stop compressing. A properly sealed Energy Star Zone C unit closes the pathway completely, which is the change most homeowners notice first.

### Foggy or Failed Glass Units

Haze and mineral staining you cannot wipe off, trapped between the panes.

The perimeter seal on the insulated glass unit has failed and the argon has escaped. If the frame is sound we swap only the glass unit, which costs a fraction of full replacement.

### Confusion Over Ratings and Rebates

U-factor, Zone C, Greener Homes, HER+, and no clear answer on real installed cost.

We state the U-factor per opening in writing, price each window individually, and explain the rebate assessment sequence before you commit rather than after.

### Inconsistent Subcontracted Installs

You meet a salesperson, then a crew you have never spoken to arrives.

Every installation is carried out by our own in-house crews. The company that measured the job is the company that installs it and warranties it for 10 years.

We diagnose first and quote second, including telling you when a repair beats a replacement.

## How a Mississauga Project Runs

Five stages from first phone call to warranty registration. No surprises in the middle.

1.  01
    
    ### Free In-Home Measure
    
    About 45 minutes. We measure every opening at your Mississauga home, check frame and sill condition, and confirm whether retrofit or full-frame is right for each one.
    
2.  02
    
    ### Written Specification
    
    Itemised pricing per opening with the glazing package, U-factor and installation method stated. You can compare it line by line against any other quote.
    
3.  03
    
    ### Manufacture & Delivery
    
    Units are built to your measurements. We confirm the delivery date before booking the crew, so your home is never opened up waiting on product.
    
4.  04
    
    ### In-House Installation
    
    Our own crews remove, flash, insulate, seal and trim each opening. Most homes in the area are complete in one to three days with the site cleaned each evening.
    
5.  05
    
    ### Walkthrough & Warranty
    
    We check operation and locking on every unit with you, hand over care instructions, and register your 10-year labour warranty.

\[ Logistics \]

## Working Across Mississauga

Mississauga jobs route off the QEW, the 403 and the Hurontario corridor. Subdivision streets in Erin Mills, Meadowvale and Churchill Meadows have wide driveways and generous setbacks, so staging is easy and crews can work from the truck without blocking the road.

Most Mississauga subdivision homes are 20 to 40 years old with consistent opening sizes across a street, which makes measuring and ordering predictable. Whole-home projects typically finish in one to two days; larger Lorne Park and Mineola homes with feature glazing can run to three.

\[ Housing Stock \]

## Mississauga Housing Stock We Know Well

**Subdivision detached homes** in Erin Mills, Meadowvale and Churchill Meadows were largely finished with builder-grade double-pane vinyl. Typical failures are fogged glass, sticking sashes and drafty meeting rails rather than structural rot. Good candidates for retrofit inserts or glass-unit swaps.

**Older Port Credit, Clarkson and Cooksville homes** are more varied, with wood-framed openings that often justify full-frame brick-to-brick replacement.

**Lorne Park and Mineola properties** are larger and more design-led, and are where we most often specify European tilt-and-turn systems and lift-and-slide patio doors.

\[ Mississauga FAQ \]

## Mississauga Questions, Answered

### Do you serve all of Mississauga?

Yes. Port Credit, Streetsville, Erin Mills, Meadowvale, Clarkson, Cooksville, Lorne Park and the surrounding subdivisions.

### How long does a Mississauga window project take?

One to two days for most subdivision homes. Larger Lorne Park or Mineola properties with feature glazing can run to three.

### What does it cost to replace windows in Mississauga?

$600–$1,200 per vinyl window installed, plus roughly $900–$1,800 per opening for triple-pane upgrades. Whole-home projects usually land between $8,000 and $18,000.

### Can you just replace the foggy glass units?

Yes, when the frame and hardware are still sound. It's the most common fix on 20-to-30-year-old Mississauga subdivision homes and it costs far less than full replacement.

### Are Mississauga installs rebate eligible?

Our Energy Star Zone C certified installations qualify for the Canada Greener Homes Grant and Enbridge HER+, subject to registered energy assessments.
