In Markham, small excavation jobs start around $3,000–$8,000, foundation digs for home additions run $15,000–$35,000, and pool excavation lands at $5,000–$15,000. Markham’s dense clay soil can affect pricing, so every quote is free and site-specific.
Always. Before any Markham excavation we request utility locates through Ontario One Call (1-800-400-2255) — it’s required by law and protects your property from struck gas, hydro or water lines, which are common under Markham’s established neighbourhoods.
A standard Markham foundation dig takes 1–3 days and pool excavation 1–2 days. Heavy clay and tight side-yard access on older Markham lots can add time, which we flag in the quote.
Clean fill can be regraded on-site or hauled to an approved York Region facility; contaminated soil needs special disposal. We test, assess and advise before we dig.
Yes — we lower Markham basements with underpinning and bench-footing. This needs stamped structural engineer’s drawings and a City of Markham permit, both of which we arrange.
