Ventilation and humidity assessments in Brampton

Condensation on windows, musty basements and stuffy bedrooms are ventilation and humidity problems, and they're easy to confuse with insulation problems. A ventilation assessment measures which one you have.

Each house stands for one in ten of Brampton's 155,800 houses (single-detached, semi-detached, row and duplex), drawn by when it was built. The glow shows the usual pattern: older houses tend to be leakier and less insulated. Snowfall scales with heating degree-days.

Why Brampton homes get humidity problems

Brampton gets about 3,664 heating degree-days a year and has a winter design temperature of −18.3°C, according to NRCan's HOT2000 climate data for Toronto International. On Brampton's coldest days, window glass and poorly insulated corners get cold enough for condensation at humidity levels that feel normal indoors, so winter humidity needs to stay at the lower end of the comfortable range.

Of Brampton's 155,800 houses (single-detached, semi-detached, row houses and duplexes), 3% were built before 1961 and 33% before 1991, according to the 2021 Census. Newer houses (53% of Brampton's were built since 2001) are tight and usually have an HRV or ERV that needs balancing and cleaning. Older houses that get air-sealed can lose the accidental ventilation they used to rely on.

What the assessment measures

  • Relative humidity in living areas and the basement.
  • Actual airflow from bath and kitchen fans, and whether they vent outside rather than into the attic.
  • How much fresh air the house gets, and whether an HRV or ERV is balanced.

Ventilation and humidity assessment in Brampton: common questions

HRV or ERV?

Both bring in fresh air and recover heat. An ERV also transfers some moisture, which helps keep very dry winter air from getting drier; an HRV suits houses that tend to run humid.

Why did condensation appear after we got new windows?

Tighter windows cut accidental air leakage, so humidity builds up. The fix is usually controlled ventilation, not leakier windows.

Is a ventilation assessment part of an EnerGuide evaluation in Brampton?

Advisors assess ventilation and humidity during the evaluation; HRV or ERV sizing may be an extra service.
