What a insulation costs in Burlington
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 Burlington
In Burlington, the average January low is -7°C, colder than 69% of the 123 cities we track. Sealing air leaks and topping up the attic usually pays back fastest here. Basement walls and rim joists are often the next biggest heat loss in older homes.
Most rebate programs pay only after an energy assessment, and some need one before the work too. Book it first.
