Frequently Asked Questions
Frequently Asked Questions About Home Insulation & Air Sealing
Whether you’re looking to lower energy bills, improve indoor comfort, or make your South Londonderry home more energy efficient, here are answers to common questions homeowners ask before upgrading their insulation and air sealing.
How do I know if my home needs new insulation?
Common signs include uneven temperatures between rooms, drafts, high energy bills, and HVAC systems that run frequently. Older homes often have insulation that no longer meets modern efficiency standards. A professional assessment can determine whether additional insulation would be beneficial.
