Another item you may want a company to cover is the financing and that is when you need to pay them. As part of the countertop replacement estimate, this should be written down if the monies are due at the beginning of the project. In payments or when the job is completed to the customer's satisfaction. If you want the companies to finance the project then ask them upfront if this is a service that they provide since not all companies offer financing to their customers. They may suggest a financial institution that they work with that you can apply to get the monies. Do not leave the financing question until the end. Once you have decided on the best countertop replacement estimate then schedule it and get it done.
