Energy-Efficient Renovation in Vaughan
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. In Vaughan, most homes date from the 1980s onward: large detached houses in planned subdivisions, with estate properties around Kleinburg.

Scope
What is included.
- Air sealing of walls, attics and rim joists
- Wall, attic and basement insulation
- High-performance windows and doors
- Heat pumps and efficient heating and cooling
- Heat-recovery ventilation
- Coordination with energy advisors for assessments
Cost
What it costs.
By quote

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.
