a. Have a clear understanding of what each supplier or contractor will provide and where it fits into the schedule.
b. Make certain that if the contractor or installer is responsible for tear-out and disposal that it is included in the price.
c. You want to avoid living without your kitchen as much as possible so do not allow tear-out until all materials are on hand or that your are certain of delivery.
d. For projects that include structural or mechanical changes, consult an architect or building contractor.
e. Remember that your sink will be removed before the old counter top is removed and plumbing for the new sink cannot be installed and connected until the water is turned on again; the new counter top cannot be installed until the cabinets are installed so make sure the counter top installer is available as soon as the cabinets are set so you will not be without water any longer than necessary.
f .If you are adding flooring, remember it goes in after the cabinetry is in place but before the appliances; make sure the appliance installer is available as soon as the flooring is completed and that the cabinet installer is prepared to come back and install the toe kick (some flooring installers will also complete this for you).
g. Ceramic tile and possibly other flooring choices require more than one day to install.
h. Make sure it is clear which installer is responsible for installing the following: the dishwasher to the plumbing line, any ductwork for the exhaust system, ceiling patching, gas and/or electrical connections.
i. Since it takes time and additional costs are usually incurred when cabinets have to be re-ordered, one of the most important items you need to have distinctly spelled out in your contract is who is responsible if there is an error. If your kitchen designer or specialist or possibly the architect provided the measurements at the job site, he or she is responsible. If not then you are responsible.
