2026-03-12 — Ottawa-Gatineau
Simple question, slightly nuanced answer: the price of a core hole depends on three things — diameter, thickness, and access. Here's the complete grid for Ottawa-Gatineau.
Important: most contractors charge a minimum trip fee ($150 to $250). A single small hole often costs the minimum — that's why grouping holes changes everything.
A 12" foundation wall takes twice as long as a 4" slab. Heavily reinforced concrete also wears bits faster.
Overhead holes, tight spaces, no water or power on site, difficult downtown parking — it all adds time.
Angle or ceiling drilling requires special equipment and longer setup.
Starting at 5-10 holes on the same site, the per-hole price drops sharply — the crew and setup are already there. Contractors and property managers: ask for an annual rate sheet.
