How to Tell if Your Siding Was Installed Improperly

Dirty Siding On House

Having replacement siding installed on your home is a great way to improve its appearance, save costs on energy bills and reduce the amount of maintenance needed on the exterior. However, there are several problems that can arise when the siding is installed incorrectly that can cause headaches for you in the long run. Check out a few common signs of improper siding installation identified by New Jersey Siding & Windows, Inc., and call us today at 973-895-1113 to get help for your siding problems.

Bulging or Warping

The exterior of your house must withstand constantly changing temperatures and weather. Because of this, it needs some room to naturally expand and contract when it gets hotter or colder. But, when it is restricted from responding to the environment, the siding will warp, bulge or even crack while trying to settle in. This movement can cause nails to pop out of the siding. The cause of this restriction is usually siding that has been nailed into place too tightly. Eliminating any wiggle room means the siding has to stretch outwards, creating a deformed look and reducing the quality of its appearance, as well as diminishing structural integrity and insulating properties.

Rusty Nails

Speaking of nails, proper siding installation should always use those made from stainless steel. This type of nail is necessary because it prevents rust, which maintains a clean look on the exterior of your home. However, if you are noticing that the heads of the nails in your siding have rust on them, the wrong nails were used by whoever provided the installation.

This can cause a couple of issues. Rusting nails can lose their strength and become susceptible to fallout, which will only cause further damage due to loosened siding. The rust on the nails can also create streaks down the siding and an unsightly appearance. If you see one of these streaks or rust on nails, then it is time to call a professional to have them replaced.


When your siding is not uniformly flat across the surface of your home, but rather dips and rises in places, then that is yet another sign that the siding was installed improperly. In this case, the ripples that you see along the siding were probably caused when the installer failed to check that his or her work was level. An installer should be taking a step back to check the alignment of the siding every couple of rows and make sure everything lines up. If they fail to do so, this can create unappealing waves. This effect is especially noticeable on the sides of your house that don’t have many doors or windows to interrupt the length of the siding.

Get Help from a Professional

When you discover one of these problems occurring with your siding, it is important to have a professional resolve any issues. Trying to fix them yourself may lead to even further damage and repairs down the line. Accidentally damaging the interior walls while trying to repair the siding can also cause structural damage and rot to your house. Pass on these potential headaches and make sure you have professionals assess the problem.
