In Richmond Hill, small excavation runs $3,000–$8,000, addition foundations $15,000–$35,000, and pool digs $5,000–$15,000. Properties on the Oak Ridges Moraine can involve sandy soil and groundwater, so quotes are free and site-specific.
Always — Richmond Hill excavation begins only after utility locates through Ontario One Call (1-800-400-2255). It’s the law and it protects against hitting gas, hydro or water lines on your lot.
A Richmond Hill foundation dig usually takes 1–3 days and pool excavation 1–2 days. Sloped estate lots and moraine soils near Oak Ridges can affect timing, which we detail in your quote.
Clean fill can be regraded on-site or hauled away; contaminated or moraine-sensitive soil requires controlled disposal. We test and advise before any Richmond Hill dig.
