What is Vinyl Siding

It is a durable plastic on the exterior of homes. Popular because of the low maintenance, durability, and easy to install and clean. Pressure washing once a year is a good idea and it costs between $3-12 per square foot.


  • Doesn’t rot like wood siding – it is made of plastic so there is nothing to rot.
  • Scratching and denting does not happen as easily as it does with aluminum – this is because the paint is baked into the siding so there is no peeling.
  • Similar look to wood- people like it because it has the look of wood and is classy
  • The range of colors, visually appealing and doesn’t need painting
  • Provides a tight seal on the home and some brands are known for Energy Star ratings

Disadvantages of Vinyl Siding

  • Some people say that it does not increase the value of the home
  • Loses color over time and you can’t repaint it
  • Doesn’t do as well in harsh climates so lifespan is less

Maintenance of Vinyl Siding

Maintenance is easy with vinyl siding. Rinse it off with a hose or pressure washer to get it clean and check the siding after bad storms.

Other Types of Siding

Wood Siding

This is known as the most aesthetically pleasing siding and lasts about 20-40 years. However, also with that comes expense and maintenance. It costs between $3-12 per square foot.


  • Wood siding is susceptible to wood rot, pests, and mold and checking for any signs of this is important each year.
  • Re-caulking may be needed around the windows to prevent leaking, especially when it rains. Also, to prevent damage and extend the life of the siding.
  • Unlike vinyl siding, the wood siding must be painted or stained and sealed every 5 – 7 years to keep out the moisture. We all know that once moisture gets in, mold or mildew can start to grow and it is a domino effect.

Aluminum Siding

This siding lasts about 30-40 years and is cost-effective. However, it requires a lot of maintenance. It costs about $2-5 per square foot.


  • After 15 years, the enamel fades, can become chalky, and wash away with the rain. Thus, repainting is needed.
  • When repainting is needed, it doesn’t match the original color
  • Denting happens more frequently as does scratching
  • Not as low maintenance as promised.

How to Know That Siding Replacement is Needed

  • The material is warping, thus water is getting underneath the siding and this can also mean that water can be getting into the home.
  • Your HVAC is working overtime and not trapping the heat and cool air indoors. You will need to repair or replace the HVAC unit if it continues.
  • You find holes, cracks, and other damage to the siding. Fixing and sealing these places is important.
  • Mold, mildew, or fungus is growing on the siding.
  • Dry and wet rot – this is giving pests a place to start going into the wood and destroying it as well as the home.

Other Areas to Inspect

When checking the siding, take a look at the roof as well. You want to make sure that you don’t have moss growing on the roof. If you do, be sure to get rid of it. Also, if you find that there is light coming through the attic or water spots, or wood rot in the attic, you may need to replace your roof sheathing.

Also, check the water inside and outside the home. If the water makes a loud banging sound after it turns off, you may have a water hammer issue that you need to have investigated before pipes possibly rupture.

When to Contact a Professional

Contact a professional if you have questions about the siding that is right for your home or any issues. Depending on where you live, one type of siding may be better than the other. Remember, cheaper is not always better and you want to find what will give you the most bang for your buck.
