Homeowner Question: My house is more humid now after completing insulation upgrades, why?
Cause: Why this is happening?
Now that your home is more air-tight the moisture in the home remains inside longer. Because of this the relative humidity levels have increased in your home.
Solution: Humidity
If the home has an HRV it may need to be rebalanced or changed to a more appropriately sized unit
If the home does not have an HRV then they may want to consider one now
Consult a ventilation specialist to determine the best course of action
A dehumidifier could also be purchased, but advise the home owner that they often use more power
