Most Langley homes built before 2000 do not meet today's BC Building Code insulation R-value requirements — and many built before 2010 fall short of what current energy efficiency programs recommend. The gaps are consistent and costly: attics at R-20 or R-30 instead of R-50 to R-60, basement walls with old compressed fibreglass batts delivering a fraction of their labelled R-value, crawlspaces with no insulation at all, and 2x4 exterior walls at R-12 when effective R-22 to R-24 is now required. Western Insulation inspects Langley homes every week and finds these deficiencies regularly — which is why we offer free assessments before recommending any work. Eligible homeowners can also access up to $5,500 in BC Hydro and FortisBC rebates on qualifying upgrades.
