Attic insulation inspections in Edmonton

The attic is usually the cheapest big energy fix in a house, and the inspection decides how to do it: how much insulation is there, where air leaks through the ceiling, and whether anything up there must not be disturbed.

What inspections find in Edmonton attics

Of Edmonton's 275,750 houses (single-detached, semi-detached, row houses and duplexes), 15% were built before 1961 and 52% before 1991, according to the 2021 Census. Attics in older houses commonly have a fraction of today's recommended insulation, and top-ups done over the years often buried air leaks instead of sealing them first.

Edmonton gets about 5,668 heating degree-days a year and has a winter design temperature of −30.8°C, according to NRCan's HOT2000 climate data for Edmonton International, the closest comparable location in that data set (26 km away). That's the 4th-highest heating demand of the 70 cities we cover. The colder the climate, the faster added attic insulation pays for itself.

Vermiculite. Loose, pebbly, grey-brown or silver-gold insulation may contain asbestos. Health Canada's advice is not to disturb it; have it sampled before any attic work. Asbestos and vermiculite testing in Edmonton

The right order for the work

  • Seal the air leaks first: top plates, pot lights, plumbing stacks, the hatch.
  • Fix ventilation baffles so new insulation doesn't block soffit vents.
  • Then top up the insulation. Burying unsealed leaks under new insulation wastes much of the benefit.

Attic insulation inspection in Edmonton: common questions

How much attic insulation should a Edmonton house have?

Advisors commonly target around R-50 to R-60 in attics. Your EnerGuide report gives the recommendation for your house.

Can I top up the insulation myself?

Only after the air leaks are sealed and you've confirmed there is no vermiculite. The inspection tells you both.

Will more insulation stop ice dams?

Insulation helps, but ice dams are mostly caused by warm air leaking into the attic. Air sealing is the bigger fix.
