How Much Does Liquid Vinyl Siding Cost?

Liquid vinyl siding is a type of spray-on siding that was first introduced in the United States in 1985. This spray-on PVC finish was first developed in England. The goal was for the siding to be a replacement for standard paint. It turned out so well that builders started to use the spray-on PVC as a siding in itself. It is not uncommon for liquid vinyl siding to last 30 years or longer if it is installed properly. Also, since this siding is literally sprayed onto the house, the installation cost tends to be a lot lower than other types of siding.

The Costs 

  • Minimum: $3 per square foot

  • Maximum: $6 per square foot

The cost of having liquid vinyl siding put on a house varies, depending on the company hired to install it. The average cost of for applying the siding on a house is between $3 and $6 per square foot. The overall cost of using liquid vinyl siding on the exterior of a 1,500-square-foot house around $4,500 to $9,000. Unfortunately, there are other costs that are often associated with having liquid vinyl siding installed. For example, before the liquid vinyl siding can be sprayed on the house, the surface has to be prepared. This can cost anywhere from $1,000 to $10,000, depending on the amount of work that needs to be done.


Few materials are needed to apply liquid vinyl siding; however, other tools and materials may be required to prepare the house before application. The process is no more time consuming than it is to paint a house.

Liquid vinyl siding does not come in many different types. Nearly all liquid vinyl siding is made the same. It comes in a variety of colors, some of which may be more expensive than others. The homeowner can choose between having the siding applied with a paint roller or with a sprayer. If a roller is chosen, a roller screen is also required. Wet film thickness is a gauge to check how thick a wet coat is being applied. This is important to make sure that the liquid vinyl siding is going on evenly around the house. A bonding coat helps protect the home against moisture and attaches the liquid vinyl siding better to the house.

Advantages and Disadvantages of Liquid Vinyl Siding

There are several advantages and disadvantages when a homeowner chooses liquid vinyl siding. Below is a complete breakdown of both, so that homeowners can make an educated decision on if this type of siding is right for their home.


One of the biggest advantages to choosing liquid vinyl siding is that it can be used on nearly any surface. Regardless if the home is covered in metal, brick, wood, concrete or traditional vinyl, liquid vinyl siding can be applied. If there are small cracks forming in the brick or concrete of a house, liquid vinyl siding can bridge those together as long as they are no larger than 1/8-inch across. Liquid vinyl siding is also easy to clean and extremely mildew resistant. This type of siding also comes in a wide variety of colors, which means that homeowners should have no problem finding the right color for their home.


The biggest con with this type of siding is it has to be installed perfectly, which can be hard to do because it goes on as a liquid. If an area of the house does not receive enough liquid vinyl siding, moisture can become trapped between the surface of the house and the siding. This can completely ruin the wood surface of a house. For this reason, it is extremely important for the homeowner to make sure to hire a contractor experienced in liquid vinyl siding application. It is wise for homeowners to check the contractor's references to ensure they are as skilled as they may claim and what types of warranties and guarantees are provided.

Also, liquid vinyl siding is said to last around 30 years; however, most houses that have received this treatment haven't reached that predicted limit. There is no way to know for sure if this estimate is accurate or not. Finally, the preparation for installing liquid vinyl siding can be extremely costly, even more so than buying the liquid siding itself.

How Liquid Vinyl Siding is Applied

Each professional contractor may have a slightly different way that they install liquid vinyl siding on a house. However, there are a few steps that are required. Knowing these steps helps give the homeowner a better idea of what all is involved in the process of installing liquid vinyl siding.

First, the contractor will inspect the exterior of a home to get an idea of the extent of work that needs to be done. Next, the surface of the house has to be cleaned and repaired if there is any damage. Once the patchwork has been done on the outside of the house, the contractor will have the home sanded and sealed to better protect the wood.

After preparing the house, the contractor puts on a bonding coat. This is a primer that helps the liquid vinyl siding bond better to the house. After the bonding coat is applied, the contractor should make one more inspection of the house to make sure that it is prepared for the application of the liquid vinyl siding. If the prep work was done correctly, the application of the liquid vinyl coating starts. This kind of coating is usually applied at 10 to 15 times the thickness of normal paint. Finally, the contractor does one more inspection of the house to ensure that the liquid vinyl coat was installed properly and does any touch-ups that are necessary.

Overall, liquid vinyl siding allows a home's siding to breathe, is mildew resistant, cleans easily and is expected to last 30 years. Although standard painting is initially cheaper, homes on average could use a new paint job every four to five years, making liquid vinyl siding a more cost-effective option over a 30-year period.
