What inspections find in Coquitlam attics

Of Coquitlam's 35,695 houses (single-detached, semi-detached, row houses and duplexes), 8% were built before 1961 and 55% 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.

Coquitlam gets about 2,851 heating degree-days a year and has a winter design temperature of −6.3°C, according to NRCan's HOT2000 climate data for Pitt Meadows. That's the 9th-lowest 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 Coquitlam

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 Coquitlam: common questions

How much attic insulation should a Coquitlam 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.
