How Much Does It Cost to Winterize an RV?

Preparing your recreational vehicle RV for the winter season is essential to protect it from the harsh elements. Winterizing an RV involves a series of maintenance tasks and protective measures to prevent freezing and damage. In this guide, we will explore the factors that influence the cost of winterizing your RV, from DIY options to professional services, and help you make an informed decision about safeguarding. 

When winter approaches, many enthusiasts wonder, How much does it cost to winterize an RV? The answer isn’t one size fits all, as the cost varies depending on several factors. Factors like the type of RV, the climate in your area, and whether you choose to do it yourself or hire a professional all play a role in determining the overall cost.

The cost to winterize an RV typically ranges from $100 to $300 or more, depending on your specific circumstances. DIY enthusiasts may spend less by purchasing winterizing kits and handling the process themselves. It’s crucial to consider your budget, location, and personal preferences when deciding how to protect your RV from the frigid temperatures of winter.

The Importance of RV Winterization

How Much Does It Cost to Winterize an RV

Before delving into the costs associated with winterizing an RV, it’s essential to understand why this process is so crucial. Neglecting to winterize your RV can lead to a host of problems, including:

Frozen Pipes and Water Damage

One of the primary reasons for winterization is to prevent your RV’s plumbing system from freezing. When water freezes, it expands, potentially causing pipes to burst. This can result in costly repairs and water damage to your RV’s interior.

Appliance and Equipment Protection

Winterization also involves safeguarding your RV’s appliances and systems, such as the water heater, refrigerator, and HVAC unit. Cold temperatures can damage these components, leading to expensive repairs or replacements.

Structural Damage

Freezing temperatures can have adverse effects on your RV’s structural integrity. This includes damage to the roof, walls, and seals. Neglecting winterization can result in leaks, mould, and structural degradation.

Mould and Mildew Growth

Without proper winterization, moisture can accumulate in your RV, creating an environment conducive to mould and mildew growth. This not only damages the interior but can also pose health risks to those using the RV.

Cost Savings

While there are expenses associated with winterization, it is an investment that can save you money in the long run. Preventing damage and the need for extensive repairs can significantly reduce your overall RV maintenance costs.

Now that we understand the importance of RV winterization, let’s break down the costs associated with this essential process.

Factors Affecting RV Winterization Costs

The cost of winterizing an RV can vary significantly depending on several factors. These factors influence the complexity of the job and the materials required. Understanding these variables is crucial to estimating the cost accurately.

DIY vs. Professional Winterization

DIY Winterization

Cost: Typically, the most cost-effective option.

Materials: Antifreeze, tools, and winterization kits.

Labour: Your time and effort.

Professional Winterization

Cost: More expensive but ensures thorough winterization.

Materials:Antifreeze, labour, and expertise.

Labour: Skilled professionals handle the process.

RV Size and Type

The size and type of your RV play a significant role in determining the cost. Larger RVs with more complex plumbing and heating systems will generally cost more to winterize than smaller, simpler models.

Class A Motorhomes: These are the largest and often the most expensive to winterize.

Class B and C Motorhomes: These mid-sized RVs are less costly to winterize compared to Class A.

Travel Trailers and Fifth Wheels: Smaller trailers may have lower winterization costs.

Geographic Location

The location where you plan to store your RV for the winter can impact costs. If you live in an area with extremely cold winters, the winterization process may be more extensive, requiring additional steps and materials to protect your RV adequately.

Warmer Climates: In regions with mild winters, winterization may be less involved.

Cold Climates: Harsh winter conditions may necessitate more comprehensive winterization measures.

Custom Features

RVs can come equipped with a variety of custom features, such as ice makers, outdoor showers, and specialised appliances. Winterizing these features may require extra time and materials, contributing to higher costs.

Luxury RVs: High-end RVs with premium features often have more components to winterize.

Now that we’ve examined the factors affecting RV winterization costs, let’s look at a breakdown of the expenses involved.

To give you a better idea of how the costs add up, let’s break down the expenses involved in winterizing an RV.

DIY Winterization

Materials Needed:

RV antifreeze: $5 to $10 per gallon.

Blow-out plug or air compressor: $10 to $50.

Hand tools for draining and bypassing water: $20 to $50.

RV winterization kit (optional but recommended): $20 to $50.

Pipe insulation (if needed): $10 to $20.

Total Estimated Cost: $65 to $180

Labour: Your time and effort, usually taking several hours to complete the process.

Professional Winterization

Materials Needed:

RV antifreeze: Typically included in the service fee.

Labour and expertise of professional technicians.

Total Estimated Cost: $100 to $200

The cost of professional winterization often includes the RV antifreeze, making the upfront cost seem higher than DIY, but it offers several advantages, including peace of mind, convenience, and professional expertise.

Additional Costs

In some cases, you may need to consider additional expenses:

Custom Features: If your RV has special features like ice makers or outdoor showers, expect to pay extra for their winterization. Costs can range from $20 to $100 or more, depending on the complexity of the feature.

Replacement of Components: If any RV components or parts are damaged or worn and need replacement, this can add to your overall winterization costs. The extent of these costs will depend on the specific parts needing replacement.

Saving Money on RV Winterization

While winterizing your RV is an important step to protect your investment, there are ways to save money without compromising on the quality of the process. One cost-effective method is to use bleach in the RV water tank, which not only helps disinfect and clean the tank but also prevents bacterial growth during the off-season.

DIY with a Winterization Kit

Opt for a DIY approach with the help of a winterization kit. These kits often come with detailed instructions, making the process more accessible for RV owners who are comfortable with basic maintenance tasks.

Learn the Process

By learning the winterization process, you can confidently handle many of the steps yourself. This reduces the labour costs associated with professional winterization.

Share Costs with Other RV Owners

If you have RV-owning neighbours or friends, consider sharing the costs of winterization materials and tools. This can significantly reduce individual expenses.

Store Your RV Indoors

Storing your RV indoors during the winter months can eliminate the need for extensive winterization in some cases. Indoor storage provides a controlled environment that protects your RV from the elements.


How many Litres does it take to winterize an RV?

The amount of antifreeze needed to winterize an RV typically ranges from 2 to 3 gallons (7.6 to 11.4 litres).

How long does it take to winterize a camper?

Winterizing a camper typically takes between 1.5 to 3 hours, depending on the complexity of the process and whether it’s done by a professional or as a DIY task.

Do I need to winterize my RV if I live in it?

Yes, you still need to winterize your RV if you live in it to prevent potential water system damage in cold weather.


Winterizing your RV is a critical maintenance task to ensure its longevity and prevent costly repairs in the spring. While the cost of winterization can vary depending on factors like RV size, geographic location, and custom features, it is an investment that pays off in the long run. 

Whether you choose to DIY or opt for professional winterization, the cost is a small price to pay for the peace of mind and protection it provides your beloved RV. Remember that you can save money by learning the process, using winterization kits, or sharing expenses with fellow RV owners.
