How to Identify the Signs of RV Delamination?

RV Delamination

Regular maintenance is crucial because RV delamination is surprisingly frequent. By the time you become aware of a problem, it may already be far advanced.

Today, we want to raise your awareness of RV delamination and provide you with prevention and repair advice.


What Exactly Is RV Delamination?

When the fiberglass or gel coat layer on an RV breaks from the backing material, this is known as delamination. Typically, lightweight plywood or luan is utilized as the backing layer in RVs. This damage can begin as a minor flaw and grow into increasingly noticeable fissures.

The process might be sped up by moisture or water leaking in.

What is the cause of RV delamination?

The failure of one or more outside seals, possibly as a result of poor maintenance, frequently leads to RV delamination. These seals prevent water from getting inside your RV and inflict costly damage.

RV seals typically deteriorate as a result of exposure to harsh weather. The RV’s seals eventually grow brittle or flaky and start to break away.


How Much Does RV Delamination Repair Cost?

If unattended, RV delamination costs increase exponentially as the harm gets severe. The best course of action is to address the issue as soon as symptoms appear. Some DIY kits cost between $100 and $300. These might be a fantastic choice for minor repairs.

However, you might need to contact experts, and even simple fixes can cost well over $1,000 and necessitate replacing the external wall. Your RV can be completely destroyed, depending on the extent of the damage.

Delamination is frequently caused by a lack of owner maintenance; hence, a lot of RV insurance and warranties do not cover it. Not only will your RV sustain significant damage, but you’ll probably be responsible for paying the full cost of repairs.


How Do You Stop Delamination?

The greatest technique to stop delamination is to stop it before it even begins. Being proactive about maintenance is a form of prevention. While operating your vehicle, check the seals on your RV frequently.

Inspect your RV every few months if it spends the majority of its time in humid or severely hot weather. A quick inspection at the beginning and end of each camping season should be sufficient, though, if you live in a more temperate climate.

Nevertheless, RV delamination cannot be stopped by simply inspecting your seals. Any problems you identify the signs must also be fixed. When seals or cracks are present, moisture can enter your RV. They must be addressed to stop the delamination.

Let’s look at the reasons behind the RV sidewall delamination, the consequences it has, and finally the solution, so you can decide how to handle it.

Identify the SignsDelamination of fiberglass RVs is a frequent issue. Delamination is the separation of the substrate layer from the fiberglass layer on an RV’s exterior wall (typically made up of thin plywood or luan wood). The outer wall’s bubbles will give under pressure as the fiberglass separates from the support.


Why Does Delamination Occur?

Anywhere there are small fissures in (or damage to the surface of) the wall, or where the roof and wall of the RV meet, moisture will find a way in between these two layers. Regular RV maintenance and inspection can nearly fully prevent the problem. Once the problem is identified, you need to locate the entry point for the moisture and seal it right away.


Grade of Damage Seriousness

Delamination might also be merely a cosmetic problem that lowers the value of your unit when you sell it. Delamination can occasionally get bad enough to affect your RV’s other parts. Even though it’s unusual, in a few rare instances, if the damage hasn’t spread too far, RV insurance might pay for delamination repairs.


When Are Delamination Repairs Covered by Insurance?

RV insurance may occasionally be covered by your comprehensive policy for the cost of delamination, according to the Florida-based Clovered insurance service. However, you’ll need to show that it didn’t come quickly and wasn’t a result of skipping RV maintenance. Hurricanes, storms, trees falling on your RV, and single-vehicle collisions (such as hitting an overpass that is lower than your RV) are all instances that could result in abrupt delamination. To be prepared for unforeseen circumstances, you should constantly keep records of your RV’s maintenance.


What is Involved in RV Delamination Repair?

Delamination must be controlled before it spirals out of control. The cost of the repairs will increase with their complexity. Depending on how far the delamination has advanced, repair costs might range from a few hundred dollars to thousands of dollars. Regardless of how serious the situation is, if you’re having this issue, you’ll want to know if your RV insurance will cover the expenses.


If you use delamination kits like this one, fixing minor delamination on your RV can be a quick DIY project.
