Frequently Asked Questions
Insulation costs in Burlington depend on the area to cover, insulation material, existing insulation, required R-value, accessibility, air-sealing work and whether old insulation must be removed. A site inspection helps determine the appropriate scope and price.
The best option depends on the attic condition, existing insulation, ventilation, moisture control, target R-value and budget. Blown-in cellulose or fibreglass are common options, while spray foam may be appropriate in specific assemblies.
Improving attic insulation and air sealing can reduce heat loss and improve comfort when the existing insulation is inadequate. Actual savings depend on the home, climate, heating system and the quality of the installation.
Not always. Existing insulation may sometimes remain if it is dry, clean and in good condition. Removal may be recommended when insulation is contaminated, wet, damaged, compressed or interfering with repairs or air sealing.
Compare experience with the insulation system you need, inspection process, proposed R-value, air-sealing scope, ventilation considerations, product specifications, warranties, cleanup, applicable certifications and recent local reviews.
Programs and eligibility can change over time. Ask the contractor whether current provincial, utility or federal efficiency programs may apply and confirm eligibility with the program provider before starting work.
