🏕️ 5 Must-Do Things for Winterizing Your RV in Whatcom County, WA

Winter in Whatcom County brings rain, freezing temperatures, and moisture — all of which can damage your RV if it isn’t properly winterized. Whether you store your RV at home or in a secure RV storage facility in Whatcom County, WA, these five steps are essential to protect your investment.

1. Drain and Protect Your Plumbing System

Frozen pipes are one of the most expensive RV winter repairs.
Drain all water lines, water heater, tanks, and add RV-grade antifreeze. This prevents cracked fittings and hidden leaks.

Pro tip: Even indoor RV storage should follow this step.


2. Fully Charge and Disconnect Batteries

Cold temperatures drain batteries quickly. Fully charge them, disconnect, and store in a dry location. This extends battery life and prevents corrosion.


3. Clean inside and out, Remove all Stored Food, and Seal the Exterior

Clean the inside thoroughly, removing any food source that would attract rodents (canned food should be ok). Wash, wax, and inspect all seals around windows, roof, vents, and doors. Re-seal any cracks to prevent moisture intrusion — one of the biggest issues in Pacific Northwest storage.


4. Protect Tires and Suspension

Inflate tires properly and use tire covers. If possible, rotate slightly during winter storage or use blocks to reduce flat-spotting.


5. Store in a Secure RV Storage Facility in Whatcom County

Leaving your RV exposed to winter weather increases risk of:

  • Mold & moisture damage

  • Theft or vandalism

  • Tree debris and storm damage

A covered RV storage facility in Whatcom County, WA provides long-term protection, security, and peace of mind.
