Quick answer

Open a Canadian cottage in this order: (1) exterior walkaround, (2) water system + septic, (3) hydro + propane, (4) dock + boat, (5) interior + pest check. Budget one full weekend and bring water, food, and headlamps in case anything's off.

Winter is hard on cottages. A patient, sequenced opening prevents burst pipes, propane leaks, and unpleasant animal surprises.

Exterior walkaround

  • Check the roof for damage, moss, and lifted shingles
  • Clean eavestroughs; check downspouts
  • Look for foundation cracks or shifting
  • Inspect chimney, siding, windows, and doors
  • Clear fallen branches; check trees for storm damage

Water system + septic

  • Reconnect and prime the water pump
  • Slowly repressurize the system — check every joint
  • Flush the hot water tank
  • Shock-chlorinate the well if applicable
  • Have well water tested annually
  • Inspect septic — pump every 3–5 years

Hydro + propane

  • Turn on the main breaker; test each circuit
  • Test GFCIs, exterior outlets, and smoke/CO alarms
  • Check propane tank level and re-open valves slowly
  • Sniff for propane leaks around fittings; use soapy water to confirm
  • Reset any electronics unplugged for winter

Dock + boat

  • Reinstall dock sections; check hardware and cribs
  • De-winterize the boat: battery, plugs, fuel line, cooling
  • Inspect life jackets — sun and mice destroy them
  • Check dock ladder + swim platform

Interior + pest check

  • Look for mouse droppings, entry holes, and chewed wiring
  • Check for water stains on ceilings + around windows
  • Test fridge, stove, hot water tank
  • Wash all linens and bedding
  • Restock first aid, batteries, headlamps, and non-perishables

Practical tips

  • Open the water system before you turn on hydro to the pump — a dry pump running is how motors burn out.
  • Bring drinking water for the first day. Well water isn't safe until tested.
  • Keep a running list of small repairs — do them mid-summer, not on closing weekend.
