🔹 Average Lifespan
Most attic insulation can last 20–30 years when installed correctly and left undisturbed.

🔹 When to Top Up
You may need to top up insulation every 10–15 years, especially if:

• You’ve noticed rising energy bills

• Rooms feel drafty or temperature fluctuates

• You’ve had roof leaks or pests in the attic

• Your insulation level is visibly below the joists

🔹 Quick Self-Check
If your attic insulation is below the height of your joists (the wooden beams), it’s likely time for a top-up.

🔹 Local Considerations (Ontario)
Ontario’s changing seasons and harsh winters can compress or settle insulation faster—regular checks every few years are recommended.

• Fluctuating Indoor Temperatures
  Rooms feel too hot in summer or too cold in winter, despite a working HVAC system.

• Rising Energy Bills
  Heating and cooling costs steadily increase due to energy escaping through the attic.

• Drafts and Cold Spots
  Noticeable cold air near ceilings, walls, or attic access points.

• Pest Activity
  Signs of rodents or insects nesting in the attic may mean your insulation is compromised or disturbed.

• Moisture or Mold
  Damp or moldy insulation indicates poor ventilation or roof leaks affecting performance.

• Compressed or Settled Insulation
  Insulation no longer fluffy or level with joists—reducing its effectiveness.

• Mold & Mildew Growth
  Poor insulation leads to condensation and trapped moisture, creating ideal conditions for mold and mildew in the attic and walls.

• Ice Dams & Roof Damage
  Heat escaping through the attic melts rooftop snow, which refreezes at the eaves — forming ice dams that can damage shingles and cause leaks.

• High Heating & Cooling Costs
  A poorly insulated attic forces HVAC systems to work harder, driving up utility bills and wearing out equipment faster.

• Water Stains on Ceilings & Walls
  Inadequate insulation can allow warm air to meet cold surfaces, leading to condensation and visible water damage inside the home.

• Pest Infestations
  Thin or disturbed insulation provides easy access and nesting areas for rodents, insects, and birds.

• Warped Wood & Structural Strain
  Repeated exposure to temperature fluctuations and moisture can damage framing, sheathing, and ceiling drywall over time.

Topping up your attic insulation is a smart, efficient solution — especially in Ontario, where existing insulation often remains dry, intact, and effective. Instead of tearing everything out, a top-up simply adds a new layer of blown-in insulation over what’s already there, boosting performance without extra mess or cost.

🔑 Key Benefits of a Top-Up Approach:

• 💰 Cost-Effective
  Avoids the high labour and disposal costs of full insulation removal.

• ⏱️ Quick & Clean Installation
  Fast, non-invasive process — usually completed in just a few hours.

• 📈 Increased R-Value
  Brings your attic up to today’s insulation standards, improving temperature regulation.

• 🌍 Eco-Friendly Choice
  Reduces waste by preserving functional existing insulation.

• 🏠 Better Year-Round Comfort
  Keeps your home warmer in winter, cooler in summer, and takes stress off your HVAC system.
