Why Is My Vinyl Siding Bubbling?

Signs Your House Needs New Siding

Vinyl siding is one of the best types of sidings a person can get. Vinyl is more durable, and when used on the siding of your house, it makes it look much better. Plus, you get no dents or dings, but you do get one of the most beautiful homes on the block. 

It essentially blends quality with beauty, so it’s perfect for people who want a beautiful siding but don’t want to worry too much about it in the long run.

However, vinyl siding is not perfect. Its imperfections and problems are far less common than with other types of siding, but they are still there. One of those is the appearance of bubbling or blistering. It’s when your vinyl siding starts showing noticeable issues in the forms of bubbles or bulges. 

So why does this happen? More importantly, how do you take care of it and stop it from happening again? We’ll cover the answers to all of these questions and more in this piece.

The reasons for vinyl siding bubbling

Vinyl siding is appreciated by many and hugely popular, mostly due to its versatility. It’s durable, can handle extreme weather, and most notably can withstand very high temperatures. However, the last of these is precisely the reason behind the appearance of bubbles and blisters.

Heat has this effect on a lot of materials, which you can notice when you put something with paint close to a fire. The color quickly starts to form bubbles and blisters, and it can quickly be ruined. The same thing happens to vinyl siding if it’s affected by constant, extreme heat. The heat can come from the inside, when your walls are not insulated enough and when your heating is continuously set to maximum output. 

Such a situation is very rare as vinyl siding is extremely heat resistant. However, other direct heat exposures can cause bubbles. These situations are usually very obvious, like a grill that’s too close to the siding. 

However, it is sometimes less obvious. Sunlight can sometimes cause the occurrence of bubbles and blisters. The reason behind is rarely direct sunlight (even during scorching summers) as vinyl siding is designed to withstand direct sunlight. The more common reason is sunlight that’s reflected off of windows on neighboring houses or buildings. 

Take a closer look at your siding – the bubbling effect is probably very localized. Take a look around and see where the sunlight might be coming from. It might take you a while to find the exact culprit, but when you do, you can ask your neighbor to install screens on their windows or something similar that will prevent sunlight from reflecting toward your house.

Key takeaways

So, these are all the reasons that can cause your vinyl siding to start bubbling. As you can see, you can easily deal with the problem and prevent it from happening in the future. However, you still need to sanitize the existing problem. You can deal with the existing bubbling by replacing the vinyl panels in that specific location. There’s no need to replace the whole siding. We at 1-800-HANSONS can do this for you quickly and easily for a fair price, so feel free to request a free in-home siding demonstration from us.
