When it comes to home comfort and energy efficiency, insulation plays a major role — but it’s often out of sight and out of mind. If your home isn’t staying as cool in the summer (or as warm in the winter) as it used to, your insulation could be to blame.
Here are five signs it might be time to update or replace your home’s insulation:
1. Your Energy Bills Are Creeping Up
Have your cooling (or heating) costs steadily increased over the past year? Poor insulation means your HVAC system has to work harder to maintain your desired temperature — which leads to higher bills.
2. Rooms Feel Uneven in Temperature
If certain rooms are noticeably warmer than others in the summer, or if drafts are common in colder months, it’s a red flag that insulation isn’t doing its job evenly throughout the house.
3. You’re Noticing More Moisture or Mold
Proper insulation also acts as a barrier against moisture. If you’re spotting mold or signs of excess humidity (like condensation on walls or ceilings), insulation that’s degraded or missing could be part of the issue.
4. Pests Are Finding Their Way In
Rodents and insects often enter homes through small gaps — and deteriorated insulation can make it easier for them to get in and nest. If you’re seeing more bugs or hearing things in the walls or attic, it could be a sign your insulation is compromised.
5. Your Home Is Just Old
If your house was built decades ago and hasn’t had an insulation upgrade, it’s likely underperforming by today’s standards. Newer insulation materials are far more efficient, and even adding a layer of modern insulation can make a big difference.
Good insulation makes your home more comfortable, more energy-efficient, and even quieter. If you’re seeing any of these signs, it might be time to call in a pro for an evaluation — or at least take a peek in your attic to see how things are holding up.
