How To Find Holes in Your Insulation (And What To Do About Them)
  • Opening Intro -

    Your home is your shelter from the elements.

    Hopefully, you have a lot of nice days or even nights where you can keep the windows open and enjoy the fresh air.


However, there are going to be plenty more times you don’t feel comfortable with the weather outside. The insulation in your home helps your HVAC maintain a healthy temperature, but it might also develop problems.

Knowing how to find holes in your insulation is a crucial skill, but knowing what to do about them is also important.

How To Find Holes in Your Insulation

Start with your attic, if you have one. Check along pipes, wires, chimneys, hatches, and windows. Just holding your hand up should be enough to determine if there is airflow going on. Any airflow indicates a hole in the insulation.

Something else to look for is color changes in any visible insulation. When there is a hole present, air will move by over the course of time.

It carries moisture and humidity, and that will make the insulation around the hole change in color.

While you are in the attic, look for signs of animal activity. Animals have to get in somehow, usually through a hole in the roof and insulation.

Remember, any scratches, dung, or feathers could indicate a hole.

Unfinished basements usually have their insulation still exposed. There are likely to be even more wires and pipes down here than in the attic, so there are more connections to check for holes and discoloration.

Take a close look around at the insulation in the basement. Look for leaks and other signs of water damage as well while you are down there.

Thermal cameras can detect localized changes in temperature that might indicate a breach of some sort. So on the off chance that you have a thermal camera, you may want to use it to take a look at your insulation.

Film the roof and look for any inconsistencies. If an inconsistency is major enough, you have a breach.

You can always call in a professional to do this. They will have industry experience and technology appropriate to the task at hand. At the very least, they’ll know what they’re looking for since they have lots of professional experience in this kind of thing.

What To Do About Them

Depending on the kind of gaps you have in your insulation, you can possibly use one of two choices. If it’s an actual hole in fiberglass insulation, then a polyurethane spray foam might be perfect for filling in any open spaces that need reinforcement.

On the other hand, if it’s something like a door or a window, then you might just want to caulk it to seal it up. This is also useful in cabinets, kitchens, and bathrooms. The caulk will seal off the hole and prevent any air from escaping your home, causing thermal issues.

Checking for holes in your insulation isn’t how you want to spend a Saturday, but it’s worth doing on occasion or when you might suspect there’s a problem.

Luckily it shouldn’t take too long and if you do it regularly it will become a normal task. And if you know what to do about holes in your insulation, then you can rest easy at night knowing you have taken care of the situation.
