How to Compare Vinyl Siding Estimates How to Compare Vinyl Siding Estimates

Many newly built homes use vinyl siding because it is durable and, at the same time, affordable. Vinyl siding is chiefly made from polyvinyl chloride or PVC making it more weather resistant than other types of sidings. In addition to withstanding harsh weather conditions, vinyl siding is also resistant to termites and other pests.

There are different vinyl siding options from which to choose; all of which come in a variety of colors and styles. Here is what you need to consider when buying and installing vinyl siding.


The first consideration when comparing vinyl siding estimates is the quality of the materials being quoted in each estimate. There are a number of different qualities that should be considered; these include the stiffness of the material and the durability of the colors.

Vinyl siding should neither be too rigid of too soft; they should be some flex in the panels. You should also compare the insulation values.  Most sidings have R-values of less than 1.0. Newer types of vinyl sidings use solid foam cores which raise the R-value to 4.0; the energy saved qualifies these products for the Energy Star label.

Vinyl siding comes in many colors; however, many vinyl siding products may be subject to fading. There are approximately 300 or more colors available in vinyl siding that meet ASTM standards. When comparing estimates, check to see the products being quoted meet ASTM standards for color retention.

Vinyl siding should be resistant to winds up to 110 mph. Check to see the wind ratings on the projects being quoted.

Installation Costs

Vinyl siding is considered to be one of the least expensive sidings to install; this is because it is one of the easiest to install. Ask your contractor to differentiate labor and material costs on the estimate to facilitate quote comparisons.

Measurements and Materials Needed

Compare the measurements given in each estimate. If the measurements are not similar, consider the reasons that might account for the difference; perhaps one contractor allows for more material overage.

Consider the Thickness of the Vinyl Sidings

The thickness of the panels is the yardstick to its stability, aesthetic appearance and cost. Keep in mind that the thicker the vinyl sidings, the more stable they are. And of course, if they are more stable this would mean that they will last for a very long time. The safest choice is to get vinyl sidings that are a minimum of .40 to .45 millimeters thick.


Compare the manufacturer’s warranties on the materials being quoted in each estimate; consider whether it is worth paying more for a better warranty; this will help you cover replacement if the siding is damaged. It is also important to consider whether the contractor guarantees the work being done.  Compare the contractor policies regarding defective installation.

Additional Items

Finally, you should check to see if the vinyl siding estimates being compared contain all the same materials and services.  Trimming, crown moldings and corner boards may be included in one quote and not the other.  The removal of old siding should also be included in both estimates.
