How to deal with contractors 
Look for personal referrals. 
If you are looking to hire a contractor, all the online listings can be overwhelming and make it hard to judge to quality and record of a contractor. Begin your research by asking around trusted friends, families and neighbours.
A personal recommendation from somebody you trust is perhaps the best review you can get. Somebody who has first-hand experience of the contractor will be able to give you a clear account of their work and any problems that might have occurred.
