How Much Does It Cost To Restore A Granite Countertop?

Professional granite countertop restoration services may require you to spend about $4 to $10 per square foot.

Are Pitting And Fissures The Same In Granite?

Generally, pitting and fissures are imperfections in granite and other stone surfaces. However, the difference between these issues is their appearances.

A pit is often a tiny space that appears because of deposits in the granite surface. On the other hand, a fissure typically takes the shape of a crack. But these problems may become serious over time, especially when left alone.

What Are Alternatives To Granite Countertops?

At this point, you might also be thinking about replacing your granite countertop with another stone fixture. If so, here are some options that may pique your interest:


A kitchen stovetop and hood with off white cabinets, a tiled backsplash, and marble countertop

Marble is a heat-resistant material made from limestone. Generally, it can withstand up to 480 degrees Fahrenheit before encountering significant damage.

Apart from its high heat resistance, a marble countertop can also be a great addition to your home, thanks partly to its beautiful appearance. It can work with different indoor themes, allowing it to stay in various trends over the years.

Conversely, marble isn't a good choice if you use the countertop to cut or slice ingredients. The material is prone to scratches and may require frequent maintenance to prevent these imperfections from appearing.

Nonetheless, specific methods are available for you to use if scratches appear. You can find one particular solution to remove scratches from marble surfaces in the video below:


Slate is a rock formed by altering mudstone or shale. Like granite and marble, slate can be a visually appealing choice for your next countertop.

It’s important to note that slate is often only available in a few color choices. Some color options include black, brown, charcoal, gray, and pewter. Still, you may find slate countertops with shades of blue, green, or red on the market.

Moving forward, slate gains the upper hand when compared to granite with its compactness.

In particular, slate countertops are often non-porous, making them more resistant to pitting and other types of physical harm than their granite counterparts.

Limestone often comprises different debris, including tiny fossils and shell fragments. Like slate, this material generally only has a few color options for interested buyers to choose from the market.

Some relatively common limestone colors are shades of brown, yellow, and white.

Countertops also made with this material have reasonably high resistance from possible harm. However, its sturdiness is often lesser than granite or slate.

To Wrap It Up

Remember, pitting in granite surfaces, particularly countertops, may occur naturally. But solutions are available to seal those small gaps. You can also attempt a restoration if you're dealing with several pits on the countertop.

Remember, investigate your granite countertop first before trying to repair its pitting.
