If you like to do home projects, replacing a countertop is the perfect job for you. It is not hard but does require two people and this is because of handling the countertop itself and aligning it up when it is time to put the new one on. If you are not sure where to start then you need to start with an estimate.
You can go to a couple of companies and then a Do-It Yourself store to price out the cost of the materials. What you would want to compare is apples to apples and this means the same materials. If you are replacing your countertop with a specific material then that is the material you get your countertop replacement estimate on. In the end if you change your mind on the material you are going to use then you know what the company is going to charge for your original idea.
Sears offers kitchen remodeling services and this would be a place to start. Everyone knows the store name and a good reputation on their products and services. You may want to pick out another company in town that the local people use depending on where you live and the last countertop replacement estimate will be your own. Of course, it should work out that you are cheaper because you are not charging yourself labor costs.
A few of the things that you would want the company to describe and define for you is the material for the countertop, the other materials needed to complete that project, the initial measuring and ordering with a time frame of how long this will take to get the countertop in and the project started and then how long your kitchen will be out of commission while they are replacing your countertop. You would not want a company to take a month to do this job. Unless, it is a special order counter and color. The job itself should only take a couple of days from start to finish. If you are doing the job yourself then it may take a little longer but this is not necessarily the case to replace a countertop.
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 customers 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.
