Why this guide exists

Allweathercoating has worked with strata councils and property managers across Metro Vancouver for over 40 years. The same questions come up before every major project: what does the depreciation report actually mean? Who's supposed to pay for this? Why does the BECA cost so much more than the depreciation report estimated? What has to happen before we can bring this to the owners?

These guides answer those questions plainly — not as legal advice, and not as marketing, but as the answers a competent contractor gives a property manager who needs to understand the situation well enough to manage it. We reference BC law directly where it's relevant and link to primary government sources so you can verify for yourself.

If your building has a specific envelope issue — a leaking balcony, spalling concrete, failed sealants — our services pages cover the technical work. The strata guide is for the decisions that happen before the work starts.
