What a insulation costs in Tacoma
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 $2,250 if you qualify. Most rebates have rules (income, your current heating, a registered contractor, approval before work starts).
