How to inspect your home's insulation

Keeping your home cozy and energy-efficient is important, and good insulation plays a big part in that. Insulation helps keep your home warm in winter and cool in summer months. But over time, insulation can wear or may become less effective at maintaining temperatures in your home. This guide will help you understand how to check your home’s insulation, what signs show you may need more insulation, and when it’s time to call a professional.

What is Insulation & Why is it Important?

Insulation is material used in your home to reduce the amount of heat that escapes in the winter and enters in the summer. It’s usually found in the attic, walls, and floors that are next to an unheated space (like a garage or basement). Effective insulation reduces your energy bills and makes your home more comfortable.

Signs You May Need More Insulation

Here are some things to look for that might mean your home needs more or new insulation:

1. High Energy Bills

If your heating and cooling costs are going up, but you’re not using your heater or air conditioner more than usual, it could be a sign that your home’s insulation isn’t doing its job well.

2. Uneven Temperatures in Rooms

If you feel that some rooms are too cold in winter or too hot in summer, it could be a sign of poor insulation. Good insulation should help maintain a consistent temperature throughout your home.

3. Cold Walls, Floors, and Ceilings

Sometimes, you can tell if the insulation is lacking by touching the surfaces of your home. If walls, floors, or ceilings feel cold in winter, it’s likely that they’re not well insulated.

4. Ice Dams on the Roof

In winter, ice dams can form when heat from inside your attic melts the snow on your roof. If the insulation in the attic is poor, more heat will escape and contribute to this problem.

How Insulation Can Break Down Over Time

Insulation can get damaged or deteriorate for several reasons:

Moisture: If water leaks into your home, it can damage the insulation, making it less effective.

Age: Over time, some types of insulation can settle or compress, which makes them less effective.

Pests: Animals and insects can damage insulation by nesting and chewing through it.

When to Hire a Professional

It’s a good idea to have a professional inspect your insulation if:

  • You’re not sure what type of insulation you have and whether it’s adequate.
  • You see signs of damage or wear and tear, like water stains or areas where the insulation has fallen away.
  • You have persistent problems with temperature control in your home.

How Often Should You Inspect Your Home’s Insulation?

It’s smart to check your home’s insulation at least once a year. The best time to do this is before a change in seasons, especially before winter. This helps ensure that your home is ready to handle the colder weather. Also, if you notice any of the signs mentioned above, it might be time to take a closer look or call a professional.


Keeping an eye on your home’s insulation is key to maintaining a comfortable and energy-efficient home. Regular checks and knowing what signs to look for can help you identify when it’s time to update or replace your insulation.
