Construction and Technical Expertise
Look for a contractor who specializes in the type of project you are interested in. A contractor who is familiar with your type of project will understand important issues, such as the material specifications and the scheduling required to finish the job within your timetable.

A well-established contractor should also have an in-depth structural knowledge of the homes in your community. The more familiar a contractor is with your style of home, the better equipped he is to deal with structural issues that may arise during construction. Also, a contractor who is familiar with the structure of your home can give you a more reliable estimate than a contractor who is not familiar with your type of home.

A contractor should also be able to tell you what products and materials he would likely use for your project. He should also offer you several options when selecting products, materials, and techniques.

There are other important factors that comprise a contractor's technical expertise. Please see "Tips on Hiring a Contractor" for greater detail on issues such as building permits and warranties.

Customer Service and Communication
It is very important for a contractor to listen to, and understand your needs and wants. While discussing your project with a contractor, he should show enthusiasm for your ideas and suggest ways to make them work within your budget. A contractor should also alleviate any concerns you may have about your project. Ask the contractor for examples of how he has solved home improvement challenges that are similar to yours.

Be sure your contractor maintains a permanent phone line for easy communication. You will have questions and concerns during your project, and you will want to have them addressed as soon as possible. Communication is a key component in a successful customer/contractor relationship.

Look for a contractor who places an emphasis on customer service. He should be friendly, professional, and attentive to your ideas. When you check a contractor's references ask questions concerning the contractor's customer service. Previous customers can tell you if the contractor offers the customer service you deserve.

For more information on customer service, such as the types of questions to ask a contractor's references, please see "Tips on Hiring a Contractor."

Business Experience
It is important that a contractor have an established presence in your community. A contractor that has worked five or more years in your community is more likely to have a stable business foundation, and therefore is in a better position to back up his workmanship and warranty.

You should also examine the contractor's relationships with other experienced trade contractors (such as an electrician or plumber) in your area. Contact a specialist that you trust and ask him about a potential contractor's professional relationships.

There are many other factors that comprise a contractor's business experience, such as insurance coverage, licensing, and membership to trade associations. Please see "Tips on Hiring a Contractor" for detailed information on hiring a contractor.
