Why So Many Mississauga Attics Underperform
Mississauga grew in waves, and each wave left its own attic problems.
Post-war and 1960s homes
Neighbourhoods like Malton, Applewood, Cooksville and parts of Port Credit have many homes built long before today’s insulation standards. Many of these attics still have their original insulation, which has often settled, thinned out or gone missing in spots.
1970s and 1980s suburbs
Large parts of Erin Mills, Meadowvale, Clarkson and Erindale were built in this era. These attics usually have some insulation, but often far below what’s recommended today, with gaps around pot lights, bathroom fans and the attic hatch.
Newer homes
Even newer builds in areas like Churchill Meadows and Lisgar can lose heat if the air barrier wasn’t sealed properly during construction, or if insulation got pushed aside during later work like running cables or installing fans. No matter the age of the house, the result is the same: heat rises, slips into the attic and is lost through the roof. That shows up as uneven room temperatures, higher energy bills and, in winter, a higher risk of ice damming.

Attic Insulation Mississauga — Frequently Asked Questions
Under the Ontario Building Code’s current energy efficiency requirements, R-60 is the common target for attic ceilings in new construction. Older homes are often well below that. During the inspection, we measure what you have and recommend a level that makes sense for your home and budget.
A quick check: if you can see the tops of your ceiling joists, you almost certainly need more. The only reliable answer is to measure depth and coverage across the whole attic, which is part of our free inspection.
You may, depending on your home type, your current insulation level and the program rules in effect when you apply. We check your eligibility as part of the quote.
Not always. If the existing insulation is dry, clean and in good shape, we can usually add new insulation on top. If it’s contaminated by pests, moisture or mould, or heavily compressed, removing it first is usually the better choice.
For most standard Mississauga attics with a flat attic floor, blown-in insulation is the most cost-effective option. Spray foam is better for cathedral ceilings, rooms built into the roof, and areas where air sealing is the main problem. We’ll recommend one after seeing your attic.
We recommend it. Attic conditions vary enough — insulation depth, moisture, ventilation, pest activity — that a phone-only estimate is a guess. Inspections are free and no-obligation.
Yes — spray foam, blown-in, batt, drywall, vapour barrier, garage ceiling insulation, and AeroBarrier air sealing.
The amount of insulation your home needs will depend on a few factors – where you live and how old your home is. Different climates will require different R-values and the older your home is, the more insulation it will probably need.
Calculating savings will depend on where you live, how much insulation you’ve put in/are putting into your home, and what kind of heating system and cooling system you have in your home.
The minimum building code for an attic is R-60, but it is minimum for a reason, it is the absolute minimum a builder is required to install in a new home. If you are paying for the heating and air conditioning more is better in this case, to protect your heating and cooling dollars.
