Once you've hired a contractor and written a clear contract, prepare for an unusual relationship. You'll be living in close quarters with one or more strangers. Together, you'll be completing complex projects involving your living space. To keep things on an even keel and achieve the best results, follow the tips listed below.

• Communication is the key. Start with a contract that spells out precisely the work to be done. Don't be surprised, however, if some aspects of the job turn out differently than you expected -- that's normal for a remodeling project. If you are displeased with the way things are turning out, tell the contractor as soon as possible. The longer you wait, the more difficult -- and expensive -- corrections will be.
• Whenever there is a change in plans, put the new expectations in writing. A "change work" agreement should be just as precise and detailed as the original contract.
• Keep close tabs on escalating costs created by mid-project changes. If, for example, unexpected structural or plumbing problems are discovered when walls are opened, it will cost extra to fix them. In order to keep within budget, you may need to settle for some less expensive installations.
• Coordinate your schedules so you and your contractor are together long enough to communicate daily, but avoid getting in each others' hair. Perhaps the contractor could arrive about a half hour before you leave for work in the morning, or maybe you could make a point of returning from work before the contractor leaves. That way, you can quickly assess the work done and discuss any decisions that must be made.
• If you do not go to work, arrange to be out of the house or in another part of the house for most of the day.
• Be empathetic. Statistically, most contractors fail simply because it is a very difficult business. For instance, a mistake may be the contractor's fault, or it may instead be the fault of a supplier or subcontractor.
• On the other hand, be firm and stand up for your rights. Don't let the contractor bully you into changes you do not want. If you feel you are being taken advantage of, don't hesitate to say so. If the problem persists, call in another contractor for arbitration.
