There are several ways to tell if your home could be poorly insulated. Learn more about the telltale signs of an improperly or insufficiently insulated home.
Is Your Home Poorly Insulated?
High Energy Bills
Sudden or consistently high energy bills may be a sign that your HVAC system is compensating for heat loss.
Drafts and Cold Spots
Feeling drafts or encountering cold spots in certain areas of your home, especially near windows and doors.
Ice Dams
The formation of ice dams on the roof can be a sign of heat escaping from the home, causing snow to melt and refreeze.

Mold and Mildew
Poor insulation can lead to condensation on walls and other areas of your home, providing a conducive environment for mold and mildew growth.

Fluctuating Indoor Temperatures
Inconsistent temperatures from one room to another or variations in indoor temperature over short periods may be due to insulation issues.
Condensation on Windows
Excessive condensation on windows, particularly during the winter months, may indicate inadequate insulation and poor ventilation.
Cold Floors
Floors that feel excessively cold may lack proper insulation.
Frequent HVAC Cycling
Poor insulation may cause your heating or cooling system to turn on and off frequently.
Uncomfortable Indoor Humidity
Poor insulation can contribute to imbalances in indoor humidity levels, making the home uncomfortable.
