What inspections find in Langley attics
Of Langley's 42,165 houses (single-detached, semi-detached, row houses and duplexes), 4% were built before 1961 and 41% 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.
Langley 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 8th-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 Langley
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.

Insulation programs in Langley
Attic insulation inspection in Langley: common questions
How much attic insulation should a Langley 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.
