Permitting can be difficult, especially when it comes to heavy work like concrete, and in almost all cases, you need a permit. Check with the concrete removal company to see how they typically handle permits.
You’ll also want to check with the City of Edmonton about necessary construction permits if you have not already done so.
It would be best to ask your concrete removal contractor about licensing, qualifications, and accreditation details. Concrete removal is a dangerous job, so they should strictly meet all safety standards.
For accreditation, check and see if they are professional associations such as the Better Business Bureau or the Edmonton Construction Association.
Typically a concrete removal company will display details about safety standards on their website. But do not hesitate to ask for (further) proof regarding any accreditation or qualification.
