Warped Siding: Prevention and Repair

warped siding prevention and repair

One of the most common questions we get is, “What do I do about warped siding?” Warped siding can be caused by a variety of factors. It doesn’t matter what type of siding you have; it could happen to any type.

If your walls are bowing in or out, there’s nothing more irritating than trying to hang pictures straight on them!

Fortunately, there are some easy solutions for this problem that will keep your home looking beautiful and structurally sound.

This blog post will explore prevention methods that will help stop warping from happening in the first place as well as provide tips for repairing warped sides if prevention fails.

What Exactly Does Warped Siding Mean?

Warped siding is a condition that occurs when the boards of your sidings become uneven. It can be caused by moisture, incorrect installation, or simply poor material quality.

If you have warped siding on one side of your house but not another, it could be due to how they receive sunlight exposure throughout the day as well.

If your siding is bowing out, it may be due to the wood swelling when moisture gets in between the boards causing them to bulge outward or shrink inward depending on how wet they are.

Warped sidings that bow into your home could mean that there’s too much moisture in the walls behind it and not enough in front of it. This can also cause the siding to shrink inward or warp over time.

Repairing Warped Siding

If you’re lucky enough that your warped siding is still under warranty, be sure to contact the manufacturer before attempting any repairs yourself!

Some warranties are better than others when it comes to repairing warping.

Warped siding cannot be fixed, and must be replaced entirely. If damage is localized, you don’t need to replace the sidings of your whole house.

There are two options for replacement:

1. Replace with vinyl – Choose a lighter color vinyl siding for the outside of your home so that it does not absorb light easily.

This allows you to keep the benefits of vinyl siding, including low prices and lightweight materials.

2. Replace with fiber cement or wood – If you live in a climate with hot summers, consider replacing your siding with something that will not warp due to temperature changes. Fiber cement or wood are great options.

Prevention is the Best Medicine for Warped Siding

We all know that preventative measures are always best! There are several things you can do to prevent warping from occurring.

You should start with good ventilation in your walls, proper insulation levels, and an air barrier; then add exterior cladding that’s resistant to moisture penetration like vinyl, fiber cement, or metal.

Here are some suggestions:

1. You can make smart choices about your siding to help deal with the summer heat. When buying vinyl siding, choose colors that reflect light to help keep your house cool.

2. If you’re painting the siding of your home, go with a lighter color than the ones used on the rest of the structure. The vinyl in a house cannot handle the additional heat from dark paint, so homeowners should take this into account when painting their walls.

3. You should avoid oil-based coatings when applying them to vinyl materials because. they can make your siding more susceptible to moisture penetration.

4. Make sure you have enough insulation in the walls of your home, especially if it’s made from wood or vinyl. If there are areas where ventilation is poor, consider using a dehumidifier if humidity levels rise too high for comfort!

5. If all else fails and warping is already occurring, you should consider contacting a restoration company to help with the process. It may be able to save your siding and prevent water damage in your home!

How to Deal Further with Warped Siding Concerns?

The plastic used in vinyl can start to melt when exposed to too much heat, causing it to warp. When the sun heats up during summer months, it can cause warping in your walls.

Warped sidings are hard to handle if you don’t deal with it right away. Here are some things you must look into:

  • If you already have warped siding and want to fix it as soon as possible, contact the manufacturer for warranty information first before attempting any repairs yourself!
  • Be sure that your home’s walls are properly insulated with a vapor barrier in place on exterior walls before installing cladding or insulation of any kind. This will protect your walls from excessive moisture.
  • If you can’t get warranty information or it’s expired, don’t worry! There are still ways to save warped siding so that no water damage occurs in the home.
  • You should consider hiring a restoration company immediately if there is substantial warping on one side of your house but not the other. When you have water damage in only one area of the exterior, it’s easier to fix without needing a full replacement!
  • Apply dehumidifiers or air conditioners in hot weather if there is warping present on your house due to high humidity levels. Warping can occur when moisture penetrates the walls of your home.
  • If your siding is warped all over and not just on one side of your home, there are still some things you can do to save time and money when it comes to repairs.

The first thing you should do is make sure your walls are properly insulated with a vapor barrier on exterior walls.

You can then choose to install cladding or insulation of any kind, if needed. This will protect your home’s walls from excessive moisture and help prevent warping in the future!


In conclusion, prevention is always best when it comes to warped siding. If water damage has already occurred though, here are some things you can try before replacing your exterior walls:

  • Get warranty information from the manufacturer first if warping only happens on one side of a home or in a small area!
  • Hire a restoration company to help with the process if warping is only on one side of your home or in an area that isn’t too noticeable.
  • If all else fails, consider replacing warped siding as a last resort!
