Is Your Home To Airtight?

Here’s Why That’s a Problem (And How to Fix It)

We’re all trying to make our homes more energy-efficient, but did you know that sealing your home to airtight can actually harm your health? A super-sealed home without proper ventilation traps moisture, carbon dioxide, and pollutants leading to stuffy air, condensation, mould, and even headaches or fatigue.

So how do you keep your home warm and breathable?

Here are some quick tips

Natural Ventilation:

  • Open windows on opposite sides for 10–15 minutes a day for cross-ventilation.
  • Crack upper and lower windows to create a natural airflow (warm air rises!).
  • Keep trickle vents and wall vents clear—they’re small but mighty.

Mechanical Options:

  • Use extractor fans in kitchens/bathrooms to remove moisture at the source.
  • Consider a Positive Input Ventilation (PIV) unit to push fresh air in gently.
  • Go high-tech with a Heat Recovery System (MVHR)—great for airtight homes

Simple Signs Your House Is Too Tight:

  • Stale or musty air
  • Condensation on windows
  • Frequent headaches or allergies
  • Mold or mildew in corners
The key? Let your house breathe—naturally or mechanically. You’ll have cleaner air, a healthier home, and better peace of mind.
