Vinyl Siding Inspection Checklist and Repair Methods

Vinyl Siding Inspection Checklist and Repair Methods

Have you ever wondered why houses have vinyl siding or what vinyl itself is? Or why are there leaks, molds, and insects in your home after employing the use of vinyl sides? Maybe you have noticed non-syncing patterns in your vinyl siding at home. Do not worry! Here we cover the basic understanding of vinyl siding inspection and how to fix them.

What are the vital places to be inspected to ensure proper vinyl siding?

Specific inadequacies in vinyl sidings alter the purpose of their placement. These inadequacies will be discussed along with their proposed solutions.


Some defects from improper vinyl siding include buckling, splitting, cracks, odors, camphor fencing behind the siding, and over-building. All these defects are common mistakes in the construction process of app materials lying on the vinyl siding. An installer could wrongly place the F and J sides, set the siding at the wrong distance to the ground, cause nail defects, etc.


The F and J sides are unsuitable cuts around the corners above and below the windows and doors. They could be short trimming or good water-directing bends, allowing water into the building.


A wrong siding distance to the ground means a siding is close to the ground without a precise distance. It invites trouble as well when it is buried in the background. This allows insect and pest infestation, water entry, rotting of materials, and other possible structural damages.


Nailing defects are when a siding is done with an inappropriate nailing technique causing a buckle to the vinyl. The nail is not extremely misshaped but has a bent surface across the horizontal vinyl.

What are the proposed repair methods for inappropriate vinyl siding?

There are proper methods to follow when installing F and J sides.

  • Cut and bend the strap of the top of the J channel down to allow it to flip over the side of the J channel.


  • Turn the bottom end of the side of the J channel inward at the bottom of the window to go over the existing J channel to prevent inadequacies like water entry.


  • Create a slit at the side of the J channels longer than the height of the window or door and carve the channel at the top.


  • Mitre cut in such a way that the line of junction bisects the free flange angle at a 45 degree and bends the strap down to provide flashing over the side members.

You could also implement proper nailing and create a proper distance between the siding and the ground. A vinyl siding should be kept at least 6 inches from the ground and should not be buried. Adding a mulch bed basically invites termites into the structure. Burying the siding in mulch is the same as burying the siding in the ground.


Vinyl is not waterproof, thereby making it prone to the growth of fungi, algae, and the like. A specific subset of the larger family of molds or fungi does not grow on buildings – mildew.  It grows on plants. But people often refer to the growth of these fungi or mold on surfaces as “mildew”. There are product manufacturers who sell cleaners designed to remove molds on surfaces.
