Where you are, and what differs
Most epoxy floor failures in Niagara are prep failures, not product failures. A floor that delaminated after two years almost always went down over contaminated, unground, or cracked concrete. Thorold sits on the Niagara Escarpment, spring melt accelerates off sloped lots, and road salt gets tracked in every winter. That history shows on the concrete.
Why diamond grinding is the prep that lasts
Diamond grinding is the only prep that works long-term on salt-contaminated Niagara slabs. It removes laitance, old paint, oil contamination, and the burnished skin that prevents epoxy from bonding. Acid etching, by comparison, leaves residual contaminants and produces an inconsistent surface profile, which is why any estimate that does not specify diamond grinding deserves a follow-up question.
How to vet an installer
Confirm the installer carries liability insurance before any work starts. A WSIB clearance certificate is a weaker test for home garage-floor work than it looks: a business that only does home repairs on private residences, hired and paid directly by the homeowner, does not need to be covered by WSIB at all, so ask for the clearance but treat its absence as a question rather than automatic disqualification.
Insist on a written estimate that names the system and prep method, and get a firm cure-time timeline before the job starts. Under the Consumer Protection Act, 2002, a supplier who gives a written estimate cannot charge more than 10 per cent over it without the consumer's agreement to a documented change.
