The Essential Guide to Choosing the Right Excavation Company for Your Project
Every excavation company looks similar in a search result: a machine, a phone number, a promise. The differences only show up underground — in settled slabs, broken services, compliance problems and quotes that double. Here's how to choose before any of that is your problem.
Experience that matches your project
Ask how long they've worked, and on what. A company fluent in residential additions works differently from one that only does open-lot grading. Longevity matters in this trade: excavation mistakes take years to surface, so a company that's been answering its phone for a decade or more has been standing behind its buried work all that time.
Locates and safety: the non-negotiables
- They arrange Ontario One Call locates before digging — and say so unprompted.
- They can explain their trench-safety approach under O. Reg. 213/91 in plain language.
- They carry insurance and can show it.
- They talk about soil — where yours is going and how it's documented under O. Reg. 406/19.
The quote tells you everything
A real quote names what's included: digging, haul-off, disposal, backfill and compaction, restoration. A vague one-line price excludes them silently, and each becomes a change order later. Site visits before quoting are the other tell — ground can't be priced honestly from a photo.
Red flags
- Suggests skipping locates or permits to 'save time'.
- Prices far below everyone else with no explanation of scope.
- No physical address, no history, no references.
- Wants full payment before the work is done.
Choose the company whose answers make the underground boring. That's what good excavation is: nothing surprising, nothing settling, nothing to dig up twice.
