Make sure your contractor can prove his or her experience with vinyl siding. The installation and repair of vinyl siding requires a contractor to be familiar with the properties of vinyl. There are certain repair and cleaning compounds which can be used on aluminum siding, but not on vinyl siding. If you hire a contractor who does not have experience with vinyl, he or she may make a mistake that actually creates more damage to your siding.

You should also try to find a contractor with a reasonable amount of insurance covering his or her work. If someone gets injured on the job, you may be financially liable for that injury because it happened on your property. An insured contractor will be able to handle any financial issues that come up due to injuries or damages.

Remember to ask for an estimate from a lot of different contractors before you hire someone. This is important for a couple of very specific reasons. Primarily, it will give you a better pool of estimates to help you find a more reasonable price. It may also give you a bargaining chip to help lower the price of your preferred contractor.
