How to Tell if Your House Is Well Insulated

How do I know if my house has insulation?

There are various signs to tell if your house is well insulated. This varies according to the type of home that you have.

We’ll provide you with tips and tricks on how to identify if your house is well-insulated or not.

Energy Bills

Energy bills are one of the ways to tell if your house is well insulated.

If you notice that you’re using a lot of energy in your home, it might mean that your house is poorly insulated.

Energy bills from other homes that you visit can be an indicator to tell you if your house is well insulated.


A poorly insulated home is noisy. When the wind blows, it’s very loud in the rooms that are not insulated properly.

You can tell if your home is well insulated or not by just listening to the way that it sounds throughout the day.

If there’s a lot of noise from the house, then there isn’t a lot of insulation inside your walls and ceilings.

Water Leaks

If a lot of water leaks through the ceiling or walls, there’s less insulation inside your walls and ceilings.

If there’s a lot of moisture inside your home, it can absorb and retain heat during the night.

Cold Spots

Using your hand to feel different parts of your home’s walls, you can tell if it’s properly insulated.

If you feel that certain areas are colder than others, then there isn’t a lot of insulation inside those walls.


Many people notice that they hardly or rarely see condensation in their bathroom or kitchen when they have a well-insulated home.

But if you experience a lot of condensation in your bathroom and kitchen, there isn’t a lot of insulation inside your walls.

Areas to Check for Insulation

Walls and Ceilings

The walls and ceilings are the first places that you should check to see if the insulation is there or not. There might be some gaps within the walls where the insulation is missing.

When insulation is missing, then it will cause thermal problems during cold weather.


You should also check your floors, foundation, and window casings to ensure that they’re properly insulated.


A door is one of the other major places to check for insulation. Doors can allow cold air inside your home through cracks and gaps.

If there are gaps between your door and the frame, this will cause air infiltration and water leakage in your home.


If you plan on having a subfloor installation, then make sure that you check for insulation. It’s important to check for insulation at the foundation level before installing the subfloor.

Benefits of Being Properly Insulated

Save on Energy Bills
