What a insulation costs in Ottawa
Price depends on which areas you insulate (attic, walls, basement) and how much air sealing is needed. Ask each company for a price per area and the R-value you end up with, so quotes are easy to compare.
That could cut your cost by up to $7,700 if you qualify. Most rebates have rules (income, your current heating, a registered contractor, approval before work starts).

Why insulation matters in Ottawa
In Ottawa, the average January low is -13°C, colder than 93% of the 123 cities we track. With winters this cold, the attic is usually the best place to start. Ask the installer to seal air leaks around lights, pipes and the attic hatch before adding insulation, or much of the benefit is lost.
Most rebate programs pay only after an energy assessment, and some need one before the work too. Book it first.
