Vinyl siding is known for its strength and durability; however, this doesn’t mean that it is not susceptible to damage when exposed to certain factors. The appearance of small holes is a somewhat common problem that may affect vinyl siding, but understanding the causes of these unwanted holes in vinyl siding can help you prevent them from happening to your siding.

Let’s take a look at some of the causes of holes in vinyl siding:


Pests tend to find their way into areas of our homes that many homeowners wouldn’t even imagine to be possible. So, it is not really surprising to hear that they are some of the most notable causes of holes in vinyl siding. These pests use different mechanisms to make holes in vinyl siding.

Woodpeckers, for example, will focus on the corners of your home where the corners of two pieces of siding meet. They will peck the areas and make holes that will allow them to penetrate the siding. Carpenter bees create tunnels into the siding of your home. These tunnels will enable them to make nests on the backside of your siding. Similarly, carpenter ants usually start from the inner walls, insulation, and other interior parts of your home, as they expand their colonies, they will eventually work their way out and make holes in your siding.

It is worthwhile to note that other birds, insects, and wild animals are capable of wreaking similar havoc on your vinyl siding.


All building materials can be weakened by aging, and vinyl siding is no exception. Over time, the material of your home’s siding will become weaker due to exposure to elements as well as other factors. If your vinyl siding has been on the side of your home for decades, you should expect that with aging there is an increased risk of damage.

Notably, the damage may lead to holes and even larger cracks in various areas of the siding. It is always a good idea to inspect your siding annually for any signs of damage such as small holes.

Weather Conditions

From the moment your vinyl siding has been installed, it is constantly exposed to all sorts of weather conditions such as ice storms, hail, high wind, rain and sunlight. Ice storms and hail can penetrate the siding and cause smaller and larger holes, high winds, on the other hand, are capable of tearing your vinyl siding; thus, causing holes.

Even though you know about the negative effects these weather conditions can have on your siding, there is very little you can do to stop it.

Poor Installation

Another possible cause of holes in your vinyl siding is poor installation. If your siding is not installed properly, the nails may be too tight or placed at a poor angle. When this happens, holes may appear in your vinyl siding. Poor installation can also make your siding bulge, bend, or warp.

This is why it is important to hire the services of experienced, professional siding technicians.

If you notice holes in your vinyl siding, call a professional to come inspect your home. If left unattended, these holes may lead to rot, mold growth, insulation issues, pest infestation and a whole host of other potential issues.
