Where clients come from

  1. The offer and its conditions

    Inside the inspection condition, buyers read basement flooding and sewers for the address, and some book a sewer camera inspection.

  2. The first 90 days

    In the first months, new owners read the backwater valve page: the Building Code, the permit and the cities' subsidies.

The records to know

OfferDue's tools for this work

Each is sold once, at a flat price that is the same for every business; none is billed monthly. One that is not open to buy yet says so on its page.

The register and the line

  • Skilled Trades Ontario: public registerShows whether a person holds a certificate (or is a registered apprentice) in one of Ontario's compulsory trades, with the certificate's expiry date. Plumbing, both electrician trades, residential air conditioning and sheet metal work are compulsory trades.Check the register →
  • WSIB: clearance certificate searchShows whether a business is registered with the WSIB and in good standing. The WSIB says a homeowner hiring a contractor for repairs or renovations isn't required to hold a clearance; many ask for one anyway.Check the register →

What OfferDue does and doesn't do with this business:

  • Listing is free and shows in the order businesses were checked: no business pays for a place, a label or an order on any page.
  • OfferDue takes no fee for a client who finds a listed business, and pays none to anyone for a client.
  • OfferDue's pages say what each record shows and where it comes from: never legal, financial, insurance or inspection advice.

Public-record information, not legal, financial, insurance or inspection advice. A listing on OfferDue is not a recommendation; check licences and references yourself.
