What bonding or lien protection should I confirm before paying an Ottawa epoxy contractor?

Paying an epoxy contractor in Ottawa requires some upfront homework to protect yourself from financial risk — and the good news is that Ontario has solid consumer protection tools available to homeowners who know where to look.

Understanding Your Financial Protection Before Writing a Cheque

The most important document to understand is the Construction Act (Ontario), which governs how money flows on construction projects in this province. Under this legislation, any contractor, subcontractor, or material supplier who contributes to your project has the right to place a construction lien against your property if they are not paid — even if you already paid your general contractor in full. This means if your epoxy contractor hired a subcontractor for diamond grinding and didn't pay them, that subcontractor could lien your home. This is not a theoretical risk; it happens in Ottawa regularly on renovation projects of all sizes.

To protect yourself, you have the right to request a statutory declaration of no liens before releasing final payment. This is a sworn legal document in which the contractor declares that all suppliers, subcontractors, and workers have been paid in full. For a straightforward epoxy garage floor project, this document is simple and any legitimate contractor should provide it without hesitation. If a contractor resists or claims it is unnecessary, treat that as a significant red flag.

Ontario's Construction Act also establishes a holdback requirement of 10 percent of each progress payment, which must be retained by the property owner for a minimum of 45 days after the project is substantially completed. For a typical residential epoxy project completed in one or two days, this means holding back 10 percent of the total contract value for 45 days after the work is done. This holdback period allows any unpaid parties to register a lien before you release the final amount. Many homeowners are unaware of this right, and some contractors will not volunteer the information — but it is your legal protection under Ontario law.

Before any work begins, confirm that your contractor carries WSIB (Workplace Safety and Insurance Board) coverage. You can verify a contractor's WSIB status for free at the WSIB website using their business name or account number. If a worker is injured on your property and the contractor does not have WSIB coverage, you as the homeowner could be held liable for those costs. This is a non-negotiable item — ask for the WSIB clearance certificate before signing anything.

Equally important is general liability insurance, with a minimum of $2 million in coverage being the standard expectation for residential work in Ottawa. Ask for a certificate of insurance naming you as an additional insured on the policy. A legitimate contractor will have this document ready to share. For larger projects — say, a full basement epoxy system running $8,000 to $14,000 — you may want to confirm the coverage limit is adequate for your project scope.

On the payment structure side, be cautious of contractors requesting more than 10 to 15 percent upfront as a deposit for a standard residential epoxy job. Materials for a two-car garage coating run $500 to $1,200 wholesale, so a large deposit demand is not justified by material costs alone. A reasonable payment schedule ties payments to project milestones — deposit at signing, a progress payment when preparation is complete, and final payment after the coating has cured and you are satisfied.

Before signing any contract, read it carefully for dispute resolution language, warranty terms, and what happens if the coating fails within the warranty period. A quality epoxy or polyaspartic system should carry at least a one-year workmanship warranty from the installer.
