phone and website
2 of 3 details stated on their own site — their claims, not our checks
Not counted — no bonus earned, and nothing deducted
Our own calculation, not Google’s and not the contractor’s. Ratings from few reviews are held closer to average, because a handful of five-star reviews is not the same evidence as a long record. The items above can only add to a score, never subtract from one: a contractor scoring nothing on all of them still reaches 80 out of 100 on a strong rating alone. “Not counted” means we have no bonus to award, not that anything is wrong.
Their website says it has been working since 1978 and describes itself as category i contractor, with alberta health services.

Taken from their own website (www.greatnorthernplumbing.com), read on September 9, 2026. These are the company’s statements about itself, quoted from the page — not claims we have checked. Ask to see a licence before any gas work.
“We are a mechanical contracting company based in Calgary, that has been proudly family-owned with home-grown roots since 1978. During this time Great Northern Plumbing has earned the reputation for being a reliable, respected and highly qualified construction partner.”
