Price: In choosing the best price, make sure that you compare apples-to-apples. Compare written estimates (not verbal promises) regarding the amount of preparation, quality of materials, number of coats, etc. The lowest price is seldom the best price.
Promptness: A contractor who keeps the appointment for an estimate is more likely to arrive promptly for the job and complete the project on time.
Communications: How a contractor responds to phone calls can be an indication of your ability to contact him after the work begins. If you must wait days for a return phone call, will the same occur after the job starts?
Insurance: Adequate insurance is important for your protection. Ask to see a Certificate of Insurance.
Warranty: A professional contractor will stand behind his work and will offer a written warranty. However, if the company goes out of business (or can’t be located), your warranty is useless. The stability of the company is as important as the warranty.
Written Proposal: A well written proposal will carefully describe what is included in the job. This allows both parties to clarify any omissions or misunderstandings. The proposal speaks volumes about the professionalism of the contractor.
References: Any contractor should be able to produce a list of good references. If possible, drive by a recently completed job and look for at the quality of their work.
Consumer awareness: No two jobs are exactly alike. A professional contractor will seek to learn what you need and/ or desire. He will listen to your comments and questions, and make recommendations suited to your purposes.
Trust: A contractor may be at or in your home for a week or longer. Be certain that you feel comfortable with him.
