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 2013.

Taken from their own website (sunderbuildingsupplies.ca), 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.
“Sunder Building & Roofing Supplies Ltd. opened with a focus on dependable building supply for Calgary’s construction industry. Since 2013, the company has grown from a single location into a two-site operation with over 54,000 sq.ft of combined warehouse capacity. Our new 40,000+ sq.ft warehouse at 3875 108 Ave NE allows us to hold more inventory, support larger contractor orders, and keep pace with Calgary’s growth.”
