Trade categories

Each category page is a curated list of establishments that actually appear in allowed sources. Empty marketing blobs are not published.

• Plumbing

  Plumbing in Niagara and Hamilton is split between village shops that still answer the phone and larger contractors covering several municipalities. This directory lists businesses that appear in official open data or OpenStreetMap, then points you to Skilled Trades Ontario when you want to confirm an individual certificate of qualification.

  33 listings

• Electrical

  Electrical work in Ontario is an ESA-regulated trade. We list contractors found in Niagara’s employment inventory, Hamilton open data, or OpenStreetMap, and we link every electrical listing to the Electrical Safety Authority locator so you can confirm a contractor licence yourself.

  39 listings

• HVAC

  Heating, ventilation, and air-conditioning contractors in this region often also hold plumbing tickets. Furnace and gas work is a TSSA fuels matter. Listings here come from official inventories and OSM; use the TSSA contractor search before you book gas-line or furnace work.

  27 listings

• Roofing

  Lake-effect snow and older farmhouses keep Niagara and Hamilton roofers busy. We only publish roofing contractors that appear in the Niagara Employment Inventory or OpenStreetMap — no scraped lead-gen dumps.

  23 listings

• Landscaping, lawn and snow

  Rural Niagara still runs on seasonal landscape and snow contracts. These listings are landscaping-service establishments from official inventories, not garden centres or equipment dealers.

  34 listings

• House cleaning

  Janitorial and residential cleaning firms from Niagara’s employment inventory and OSM. Home-based cleaners that never appeared in a public inventory are not invented here — they can claim a listing.

  9 listings

• General contracting and renovations

  Residential builders, remodelers, and site contractors recorded as construction establishments in open data. For regulated sub-trades (electrical, HVAC, plumbing) check the licence badges on those category pages as well.

  74 listings

• Pest control

  A small trade locally. Every pest-control establishment we could confirm in the Niagara Employment Inventory or OSM is listed. If you operate in West Lincoln and you are missing, use the claim form.

  3 listings

• Windows, doors and garage doors

  Window, door, and garage-door shops — installers and specialty dealers that are actually in that trade, not big-box lumber yards.

  20 listings

• Painting

  Painting and wall-covering contractors only. Paint retailers and powder-coat plants are out of scope.

  7 listings

• Auto repair

  Independent garages and licensed public garages from Niagara open data, Hamilton’s licensed-garage dataset, and OpenStreetMap. Parts counters and used-car lots are excluded unless the inventory classified them as repair.

  180 listings

• Tree service

  Arborists and tree-service crews. Hamilton publishes a licensed tree-cutter register without addresses, so we only list firms that also have a public NAP in OSM or Niagara open data.
