Central Oregon winter weather can expose weak points that stay hidden the rest of the year: an outdoor faucet with a hose still attached, an irrigation component holding water, a crawlspace pipe in a cold draft, or a furnace that has not been serviced. A useful winterization plan starts with your specific property rather than a generic list.
This checklist focuses on the systems Bend homeowners can inspect before prolonged freezing weather. If a task involves gas, electrical work, climbing, compressed air or an unfamiliar shutoff, use a qualified professional.
1. Map the water system before cold weather arrives
Find the main water shutoff and confirm that everyone responsible for the home knows where it is. Keep the valve accessible, and identify any separate shutoffs for irrigation, outbuildings or accessory units. The City of Bend advises homeowners to know and protect their water shutoff and to keep it clear of snow and ice.
Walk the home and note plumbing in the places most likely to get cold:
- crawlspaces and unfinished basements;
- garages, workshops and exterior walls;
- under sinks on outside walls;
- vacant rooms where heat may not circulate well; and
- detached buildings with seasonal water service.
Insulate exposed supply lines with products designed for plumbing. If you are considering electric heat cable, use a listed product that is appropriate for the pipe material and follow the manufacturer’s installation instructions. Do not improvise with extension cords or materials not rated for the location.
2. Disconnect hoses and prepare outdoor faucets
Remove garden hoses, splitters and timers from exterior faucets so trapped water can drain. A frost-free faucet can still be damaged when a connected hose keeps water in the assembly. Inspect each faucet for a slow leak, confirm that any interior isolation valve works and use an insulated cover when appropriate for that fixture.
If a faucet or pipe is already frozen, do not use an open flame. Shut off the affected water supply if there is evidence of a split or leak and call a plumber. For a damaged City water meter or an emergency utility shutoff, use the City of Bend Water Services contact information on its broken-pipe and shutoff page.
3. Winterize the irrigation system correctly
The City of Bend’s winter guidance tells residents to winterize irrigation systems. The correct method depends on the layout, valves, backflow assembly, pumps and manufacturer requirements. Shutting off the supply alone may leave water trapped in vulnerable components.
Compressed-air blowouts can damage equipment or cause injury when the pressure, connection point or sequence is wrong. If you do not know the system’s design limits, hire an irrigation professional. OSU Extension also recommends inspecting irrigation pumps and removing water that could freeze in the pump housing; its irrigation-system maintenance guide is a useful reference for properties with pumps.
4. Protect heat, ventilation and the building envelope
Schedule heating-system service according to the equipment manufacturer’s guidance and replace or clean filters as required. Confirm that thermostats, fuel supplies and backup batteries are ready before a cold spell. The City recommends keeping a home at least 55 degrees during cold weather, including when it is vacant.
Seal obvious air leaks around doors and windows, but do not block combustion-air openings, dryer vents or equipment exhausts. For crawlspaces, look for exposed pipes and cold-air paths. The City recommends insulation blocks in crawlspace vents during extended subfreezing conditions; because crawlspace designs and moisture-control needs differ, follow the home’s design and remove seasonal blocks when they are no longer needed.
Outside, clear snow from furnace, water-heater and other appliance vents. Keep heat pumps free of snow and ice without striking or prying at the equipment. If you use a fireplace or wood stove, have the chimney and appliance inspected and cleaned on the schedule recommended for the system.
5. Check the roof, gutters and drainage from the ground
Clean accessible gutters before winter and verify that downspouts direct water away from the foundation. After major snowfall, look from the ground for blocked appliance vents, damaged gutters, unusual roof deflection or ice buildup at the eaves.
Do not climb onto a snowy or icy roof. The City advises using a licensed and bonded professional with the right equipment when roof snow must be removed. Move piled snow away from vulnerable siding, foundation openings and drainage paths, and keep nearby storm drains clear where it is safe to do so.
6. Prepare for outages without creating a new hazard
Test smoke and carbon-monoxide alarms and replace batteries or devices according to the manufacturer’s instructions. Keep flashlights, charged power banks, warm clothing, drinking water, medications and basic supplies where they are easy to reach.
Never operate a portable generator inside a house, garage, basement, shed or other enclosed space. The U.S. Consumer Product Safety Commission warns that generator exhaust can cause fatal carbon-monoxide poisoning and recommends outdoor operation following the manufacturer’s placement instructions. Review the agency’s current generator and heating-equipment safety guidance before an outage.
Space heaters also need clearance from bedding, curtains and furniture. Plug them directly into an appropriate wall outlet rather than an extension cord or power strip, and turn them off when no one is monitoring the room.
7. Make a plan for vacant or second homes
A vacant-home plan should be property-specific. Decide who will check the house after a power outage or severe freeze, how they will access it and what they should inspect. Confirm that the thermostat setting, water strategy, insurance requirements, alarm monitoring and snow-removal arrangements all agree with one another.
If you shut off or drain water systems, document the restart procedure and label valves clearly. Do not shut down fire-sprinkler, hydronic-heating or other specialized systems without professional guidance. Review the plan with the insurer; our Bend home-insurance guide explains why property use and protective systems matter to coverage decisions.
A practical pre-freeze walk-through
Before the next extended freeze, use one property walk-through to confirm:
- the main water shutoff is labeled and accessible;
- hoses and exterior accessories are disconnected;
- irrigation, pumps and seasonal water lines are winterized for their design;
- exposed plumbing is protected and known cold spots are monitored;
- heating equipment, filters and thermostats are ready;
- roof drainage and appliance vents are clear;
- smoke and carbon-monoxide alarms work;
- outage supplies and safe-heating plans are in place; and
- a local contact can check the home if you are away.
