RV Winterization Services at California RV Specialists
Winterizing your RV is one of the most important steps to protect it from cold temperatures, moisture damage, and long-term wear. At California RV Specialists, we offer complete winterization services for all RV types—travel trailers, fifth wheels, motorhomes, and toy haulers—so you can store your RV with confidence.
Winterization ensures your plumbing system, roof, sealants, vents, and exterior components are protected from temperature changes, water intrusion, and seasonal damage. Even in mild-winter regions, moisture and freezing conditions can lead to costly repairs if not addressed properly.
Understanding Winterization in the Lodi, California Area
In Lodi, California, winters are generally mild but still bring cold, wet, and cloudy conditions.
- Temperatures range from 39°F to 93°F
- Rarely below 31°F or above 102°F
Because of this, winterization in our area focuses on:
- Moisture control
- Water system protection
- Roof and sealant inspections
- Weather-related wear prevention
Even mild freezing can damage faucets, fittings, water lines, and tanks. Proper winterization ensures your RV is ready to go when spring arrives.

Winterization Steps for RVs in Our Region
1. Drain All Holding Tanks
- Fresh water
- Gray water
- Black water
Prevents freezing and bacteria buildup during storage.
2. Remove Inline Water Filters
Filters inside cabinets or exterior compartments should be removed to prevent cracking or clogging.
3. Drain or Blow Out Water Lines
We clear all plumbing lines, including:
- Exterior showers
- Inside faucets
- Toilet supply lines
- Water heater
This prevents freezing damage and internal leaks.
4. Add RV Antifreeze (If Needed)
If you plan to store your RV in colder locations—foothills, mountains, or higher elevations—we add RV-safe antifreeze to protect your plumbing system from freezing.


5. Inspect Roof Components
We check:
- Vent lids
- Skylights
- Refrigerator roof vents
- Plumbing vents
- Roof fans and misc. covers
Winter wind and moisture can cause cracking or leaks if these items are worn.
6. Check Roof Sealants
Sealants are your RV’s first line of defense.
We inspect and recommend touch-ups for:
- Roof perimeter sealant
- Roof accessories
- Roof-to-wall areas
7. Inspect Body Sealants & Windows
We look for cracking, shrinking, or separation around:
- Windows
- Moldings
- Body seams
Moisture intrusion often starts with small overlooked gaps.
8. Check Awnings & Slide-Out Toppers
We inspect the fabric, hardware, and seals to ensure they can withstand winter conditions.
9. Inspect Slide-Out Seals
Good slide seals prevent water, wind, and pests from entering your RV during long-term storage.
