Accurate measurements are crucial. Use a tape measure to determine the length and width of your countertop. To calculate the square footage, multiply all of these measurements together.

Repairing scratches on granite countertops typically costs between $10 and $60 per square foot. How much you’ll spend will depend on the area you need repaired, with repairing a single scratch costing much less than repairing an entire surface.

Alternatively, refinishing or polishing the countertop can hide shallow scratches, although you will need to fill in deeper flaws.

Expect to spend $5 to $20 per square foot to have your granite countertops professionally refinished.

After researching the material costs of granite countertops, you may consider saving on the overall price of this upgrade by installing them yourself. If you have the skills and at least one other person to help, this can be an effective way to cut down on labor costs and any additional expenses such as old countertop removal or sink cutting costs.

However, for most DIYers, it is not recommended to undertake this installation project. Instead, you should budget for the additional cost of hiring a professional granite countertop installation company. On average, you’ll pay between $35 and $85 per hour for granite countertop installation labor. Slab shipping may be included in the labor cost, but if it isn’t, you could end up paying an additional $150 to $200 in shipping costs.

Sink cutouts cost about $100 per sink, and the cost of removing the old countertop during installation is about $100 to $200. Total labor costs range from approximately $600 to $1,500, depending on the size and complexity of the project.
