Licensing, costs, questions to ask, and how to avoid bad contractors

This guide demystifies the process, providing tailored advice for selecting reliable cleaners within the province. Learn how to clearly define your needs, ask the right questions about experience with Ontario homes (including any specific seasonal concerns), check local licensing and bonding requirements, and understand contracts specific to our region. Avoid costly mistakes and ensure you hire a professional who understands the nuances of maintaining homes across Ontario's diverse climate and regulations, giving you peace of mind and a spotless result.

Ontario Licensing Requirements for Cleaning Contractors

Cleaning companies in Ontario do not require a specific licence but should carry commercial liability insurance and WSIB coverage. For mould remediation, look for IICRC (Institute of Inspection, Cleaning and Restoration Certification).

Beyond trade-specific licensing, every cleaning contractor you hire in Ontario should provide:

  • Commercial general liability insurance — minimum $2 million coverage
  • WSIB clearance certificate — protects you if a worker is injured on your property
  • Business registration — registered with the Ontario government
  • Municipal permits — where required for the specific work being done

What to Look For in a Cleaning Contractor

  1. Experience with your project type. A contractor who specialises in your specific need will deliver better results than a generalist.
  2. Strong local reputation. Check Google reviews (4.0+ rating), ask for cleaning-specific references, and look for contractors listed in professional directories.
  3. Clear communication. How quickly do they respond? Do they explain things clearly? Communication quality during the quote process predicts communication quality during the project.
  4. Detailed written quotes. A professional quote itemises labour, materials, permits, and timeline. Vague one-line quotes are a red flag.
  5. Appropriate insurance and credentials. Ask for copies. A contractor who hesitates is one to avoid.

Red Flags — When to Walk Away

  • No written contract. Verbal agreements offer zero protection.
  • Demands cash only. Reputable businesses accept multiple payment methods and provide receipts.
  • No insurance or refuses to show proof. You are taking on massive liability.
  • Quote is dramatically lower than competitors. They are either cutting corners or planning to upsell later.
  • Pressures you to decide immediately. Real professionals give you time to compare.
  • Cannot provide references. Either they are new (higher risk) or past clients were unhappy.
  • Wants full payment upfront. Standard is a deposit (10-30%) with progress payments.
