Frequently Asked Questions
Insulation reduces heat loss in winter and heat gain in summer, making your home more energy-efficient and comfortable. It also lowers energy bills and improves indoor air quality.
It depends on the area:
- Fiberglass batts – Common for walls and attics.
- Spray foam – Provides airtight sealing for attics and basements.
- Blown-in insulation – Great for hard-to-reach areas.
- Rigid foam boards – Ideal for exterior walls and basements.
Most insulation lasts 20–100 years, but it may need replacement sooner if it gets damaged by moisture, pests, or settling.
Signs include uneven temperatures, high energy bills, drafts, and cold walls or floors. A professional energy audit can determine if your home needs more insulation.
Costs vary based on insulation type and home size, ranging from $1,500 to $5,000. The savings in reduced energy costs make it a great long-term investment.
