Where does an older house lose the most heat?

Typically through air leaks, the attic, uninsulated walls and the basement, and through old windows. An energy assessment measures it for your house.

Is it worth insulating walls during a renovation?

Yes. Once the walls are open the added cost is small compared with opening them later for that purpose.

Are there rebates for energy upgrades in Ontario?

Programs exist but change frequently, and most need an assessment before the work. Check the current federal, provincial and utility programs at the start of planning.

Energy-Efficient Renovation and Insulation in the GTA

The cheapest time to make a house warmer and cheaper to run is while the walls are open for another reason. We build the efficiency work into the renovation.

Before you start

What to know.

Air sealing first
Stopping drafts usually does more for comfort than adding thickness of insulation, and it has to be done before the walls are closed.
Ventilation
A tighter house needs planned fresh air. A heat-recovery ventilator brings it in without throwing away the heat.
Rebates
Government and utility rebate programs change often and usually require an energy assessment before work starts. Check the current programs before you begin.
