To choose a siding contractor, interview three candidates, find out if they have a proper insurance and license, and receive a price estimate. Ask about the warranties and guarantees that each contractor offers, and examine their portfolio. It is also helpful to ask the contractor for references and contact them yourself.
Look for siding contractors in the prone book or on websites that list such services, and ask people you trust for referrals. Employers at a local siding material supply store or home renovation center usually know how well each contractor does their job, so ask them for tips as well. After you have found a number of contractors, choose three of them, and invite them to your home for an interview. During the interview, make sure that you are comfortable with the person, that the contractor is polite, professional and gives you all the information you request.
Make sure that the price estimate a contractor gives you is written and includes information about the services that are included in the price. Get the warranty information in writing as well. When looking through the contractor's portfolio, make sure that he has worked on projects similar to yours. If possible, visit the homes of the contractor's references to see how well the job was done and what its condition is after some time.
