1. Your Home Is Older
Insulation can last anywhere from 20 to 80 years depending on the type and conditions. But in older homes, insulation often degrades over time. If your home is more than a couple of decades old, chances are the insulation is no longer performing as it should.
2. Your Energy Bills Are Creeping Up
Have your heating or cooling costs jumped without explanation? Poor or damaged insulation allows heat to escape in winter and enter in summer, forcing your HVAC system to work harder. Replacing it can improve energy efficiency and lower your bills.
3. Musty Smells or Increased Allergies
A moldy or musty odor—or worsening allergy symptoms—can point to moisture-damaged insulation. Mold can grow in wet insulation, posing a health risk and compromising effectiveness.
4. Drafts Inside the House
If your home feels drafty even with all windows and doors shut, that’s a big red flag. Insulation is supposed to seal those gaps. Drafts mean air is slipping through, costing you comfort and money.
5. Pests in the Attic or Walls
Rodents and insects love to nest in certain insulation materials. If you’ve spotted pests—or signs of them like droppings or scratching noises—your insulation could be their new home.
6. Uneven Room Temperatures
Is one room always hotter or colder than the rest? Inconsistent temperatures often mean your insulation isn’t doing its job uniformly. This is especially common in attics and crawl spaces.
7. Water Damage or Roof Leaks
Insulation that gets wet loses its effectiveness and becomes a breeding ground for mold. Whether from a roof leak or plumbing issue, wet insulation needs to be replaced as soon as possible.
8. Settled or Compacted Insulation
Over time, insulation can shift, settle, or get compacted—especially in attics. This reduces its ability to trap air and keep your home insulated. If you notice sagging or thin insulation, it’s time for an upgrade.
9. Outdated Materials
Even if your insulation looks intact, it might not meet today’s energy efficiency standards. Upgrading to modern insulation—especially spray foam—can improve performance and help you qualify for energy-saving rebates.
🧱 How Long Does Insulation Last?
Here’s a quick look at common insulation types and their average lifespans:
-
Cellulose (up to 30 years): Eco-friendly but vulnerable to moisture, mold, and pests.
-
Spray Foam (can last a lifetime): Durable, moisture-resistant, pest-proof—our top recommendation.
-
Rock Wool/Mineral Wool (30–80 years): Fire-resistant but sensitive to water damage.
-
Fiberglass (can last decades): Effective but easily disturbed by pests and moisture.
