RV Delamination Repair Cost

RV delamination repair cost is a big red flag when it comes to managing the RV repair and maintenance cost. 

Understanding how to recognize, treat, and prevent RV delamination is a great step towards protecting your investment. In this post, we feature all you need to know regarding RV delamination. 

By the end of this post, you will find important tips helping you minimize RV delamination repair costs. 

What is RV Delamination?    

RV delamination is when the fiberglass or the siding layer of the RV starts pulling away from the substrate or the lightweight plywood used to make the fiberglass. In most scenarios, RV delamination starts as a small dent and spreads outward, leaving a huge impact. 

To understand how this occurs, let us review how the fiberglass used on RV siding is made. 

The modern RVs feature a fiberglass siding. The RV manufacturers have switched to fiberglass mainly because of the durability aspect. Moreover, fiberglass is a lighter material, ensuring the manufacturing of fuel-efficient RVs.

Unfortunately, the material found underneath fiberglass is not as durable. Owing to this, whenever there is an impact on the RV siding or the roof, the fiberglass may puncture. In case of any huge impact, there might be permanent damage, resulting in too expensive maintenance costs. 

For a majority of RV owners, RV delamination repair cost is an issue of concern. However, you can easily eliminate or control RV delamination repair costs by remaining vigilant. Keep checking the siding of your RV, and upon noticing any small dents, ensure the repair is done on time before the crack spreads.

What is the cause of Fiberglass Delamination in RVs?

Different factors will result in RV delamination. Let us look at some of the common causes of RV fiberglass delamination.

Water intrusion

Water intrusion is the most common cause of RV delamination. To understand how this occurs, consider that fiberglass is made using glue or pressing materials to ensure vacuum bonding. 

In that regard, whenever there is a water leak, the plywood used to make the fiberglass will swell, causing the glue bonding to weaken. As a result, you soon begin noticing bubbling, which is what is referred to as delamination. If left unrepaired, fiberglass delamination could necessitate complete removal or repair of the unit. 

Substandard Fiberglass Construction

In some instances, using substandard material could result in fiberglass delamination. In case the bonding process is not done perfectly, the glue fails to maintain the bond; hence delamination starts occurring. 

However, substandard construction is a less common case since RV manufacturers are keen to ensure high-quality materials. To avoid becoming a victim of RV delamination caused by substandard construction, always purchase the RV from trusted dealers. 


On rare occurrences, RV delamination occurred due to an impact on the RV siding. The impact on the RV siding breaks the outer fiberglass panel, which damages the Styrofoam and the plywood that is beneath the fiberglass. This causes the bonding to fail, resulting in RV delamination. 

How do you Recognize RV Delamination? 

Knowing the signs of RV delamination is an important step. This is regardless of whether you are in the market for a brand new RV or you own an RV, and you are concerned about the RV maintenance procedures. 

Fiberglass sidings on your RV should appear flat and smooth. Park the RV where there is direct sunlight and do a thorough inspection of the sideways. Be keen to inspect using your fingers.  

In case you notice any bubble formations or waves and creases, this is one of the warning signs that you may be battling RV delamination soon. 

Using your fingers, press on the RV siding, to feel if there is any spongy feeling. In case you suspect a spongy feeling, you can confirm this using a plastic spoon to confirm if it is a hollow formation. 

Either of the above signs indicates that you could be dealing with RV delamination soon. Therefore, if you are shopping for a new RV, you should avoid the one with those signs of delamination.

If you noticed these signs on your RV, it could be time to stat budgeting for the RV delamination repair cost. If you do not act with speed, the RV delamination repair cost will keep rising, as the issue gets worse.

Will Insurance Company Cover RV Delamination Repair Cost?

A majority of insurance companies does not cover RV delamination repair cost. The insurance companies expect that RV owners should ensure proper maintenance of their rigs to prevent RV delamination. Owing to this, RV owners have had to cater to the RV delamination repair cost out of pocket. 

To ensure that you do not spend too much on RV delamination repair cost, you should consider a periodical inspection of your rig to identify any signs of delamination. Handle the issue while it is still fresh to prevent the spread to other parts of the RV. Note that the overall RV delamination repair cost depends on the extent of the damage. 

How do you Prevent RV Delamination?

RV sidewall delamination is not easy to stop once it has started. Consider that mold will grow in the case of delamination caused by water leaks. Therefore, RV delamination continues, which is a serious damaging issue. 

You can prevent RV delamination from spreading by using a sealant on the seams. Thus, if you notice the RV seams wearing out, talk to an expert to help in resealing the outer seams. This keeps the fiberglass intact, stopping RV delamination. 

If you notice RV delamination, talk to an expert. This helps to control the RV delamination repair cost. 

Fiberglass is a lightweight material, hence suitable for RV sidewall construction. Compared to aluminum, fiberglass is easy to maintain and much more affordable. As a lightweight material, manufacturers have used fiberglass to deliver fuel-economical rigs. 

Unfortunately, delamination occurs as the rig ages.  This means that RV owners might need to budget for RV delamination repair costs. As illustrated, you can control the RV delamination repair cost easily.
