Maintenance Tips for Blanket Insulation: Keeping Your Home Efficient

15 May 2025

Custom Insulation Company, Inc. - Thermal Batt Insulation

Proper insulation is key to maintaining a comfortable, energy-efficient home. Blanket insulation—whether it’s fiberglass, mineral wool, or cotton—helps regulate indoor temperatures and reduce your energy bills. However, like any other part of your home, it requires regular maintenance to continue performing at its best.

At Custom Insulation Company, Inc., we believe in not only installing high-quality insulation but also ensuring that it stays in optimal condition. Here are some simple maintenance tips to help keep your blanket insulation working efficiently and effectively for years to come.

1. Inspect Your Insulation Regularly

Just like other areas of your home, insulation requires occasional check-ups. Make it a habit to inspect your insulation—especially in places like attics, basements, and crawl spaces—at least once a year.

  • Look for damaged or displaced sections. Insulation can settle over time or be affected by water or pests.
  • Check for moisture. Water damage can compromise the effectiveness of insulation, leading to mold and mildew growth.

If you spot any issues, call an insulation professional to repair or replace the affected insulation. At Custom Insulation Company, Inc., we offer expert assessments and quick fixes to keep your insulation in top shape.

2. Keep Pests Away from Your Insulation

Rodents and insects love to make nests in insulation, which can significantly reduce its effectiveness. To prevent pest problems:

  • Seal any cracks or gaps in walls, floors, or ceilings where pests could enter.
  • Install barriers in areas known to be susceptible to rodent infestations, like attics and basements.

If you suspect pests have gotten into your insulation, it’s crucial to address the issue quickly to avoid further damage. Our team can help you with pest-resistant insulation options and repair services.

3. Watch for Signs of Water Damage

Moisture is one of the biggest threats to blanket insulation. It not only reduces the insulation’s performance but also encourages mold and mildew growth, which can affect indoor air quality.

  • Inspect for leaks in your roof, windows, and pipes that could be allowing water to enter.
  • Fix any leaks immediately to prevent water damage to your insulation.

If your insulation becomes wet, it’s often best to replace the affected areas rather than trying to dry them out. At Custom Insulation Company, Inc., we can help assess water damage and recommend appropriate solutions.

4. Ensure Proper Ventilation

Good airflow is essential for maintaining the effectiveness of your insulation. Without proper ventilation, moisture can get trapped, leading to mold growth and reduced insulation efficiency.

  • Ensure vents are unobstructed in areas like attics and crawl spaces.
  • Use exhaust fans in areas like bathrooms and kitchens to help circulate air and reduce humidity.

Proper ventilation not only keeps your insulation dry but also contributes to overall home comfort and energy efficiency.

5. Monitor Temperature Fluctuations

While blanket insulation works to keep your home comfortable, it’s important to be mindful of extreme temperature changes. Sudden temperature shifts can cause the insulation material to expand and contract, potentially leading to gaps and uneven coverage.

Maintain a consistent indoor temperature to prevent unnecessary stress on your insulation.

If you notice any areas where the insulation appears uneven or compromised, it’s a good idea to have them checked by a professional.

6. Keep Insulation Clean

While blanket insulation doesn’t require regular cleaning, keeping it free of dirt and dust can help ensure it continues to perform well. Use a gentle vacuum or air blower to remove any debris that may have collected on top of or near the insulation.

Be cautious when cleaning insulation to avoid disturbing the material or causing any damage.

7. Professional Inspections & Upgrades

Even with regular maintenance, some insulation may need to be replaced or upgraded over time. If your home is older, or if your insulation has been in place for many years, it may be time to assess its efficiency.

  • Schedule professional inspections to ensure your insulation is still doing its job.
  • If your energy bills are rising or you’re experiencing discomfort in your home, consider upgrading to more energy-efficient insulation solutions.

At Custom Insulation Company, Inc., our experts can evaluate your insulation and recommend the best options for keeping your home as energy-efficient as possible.

Keeping Your Home Comfortable, Efficient, and Safe

By following these simple maintenance tips, you can ensure your blanket insulation continues to work effectively, keeping your home energy-efficient, comfortable, and safe for years to come. Regular inspections, proper ventilation, and prompt repairs are key to maintaining the performance of your insulation.
