Stone Countertops questions, answered by experts

The frequency for sealing granite countertops depends on several factors, including the type of sealant used, the color of the granite, and how heavily the countertops are used. As a general guideline, resealing is often recommended every 12 to 18 months, but some sources suggest it could be as often as every few months or at least once a year.

The type of sealant is a major factor: water-based sealants may need reapplication every six months to a year, while more durable solvent-based sealants can last for five to 10 years. Additionally, factors like heavy kitchen traffic, frequent use of acidic cleaners, and lighter granite colors may require more frequent sealing to prevent staining.

To determine if your countertops need resealing, you can perform a simple water test. Place a few drops of water or a wet paper towel on an inconspicuous area of the granite. After 10 to 15 minutes, check the spot. If the water has beaded up, the seal is still intact. If the water has been absorbed and darkened the stone, it's time to apply a new coat of sealant. You can choose to seal the granite yourself or hire a professional to ensure it's done correctly.

Onyx countertops are naturally porous, absorbing liquids and staining easily without proper care. Regular sealing every 6 to 12 months is essential to keep them looking their best. Daily maintenance includes wiping up spills immediately and avoiding harsh cleaners or acidic substances that can etch the surface. 

Cultured stone is typically easier to cut compared to natural stone. Because it’s lightweight and porous, cutting cultured stone doesn't take as much effort. The process of cutting cultured and natural stone is the same; however, you may spend more time cutting through natural stone.

The timeline to install countertops largely depends on the materials and the job size. Installing granite countertops takes anywhere from two to seven hours, though complex designs can pass the eight hour mark. Average-sized quartz countertops take two to five hours to install, though most pros will recommend a 24-hour settling period. Marble, on the other hand, is finicky and can take up to two whole days to install. No matter how you slice it, however, a professional is going to complete the job much quicker than an amateur.

Quartzite is more expensive than granite, largely because of its rarity. Granite is naturally more common. A granite slab generally costs $40 to $60 per square foot (excluding super-rare types), while quartzite slabs cost anywhere from $50 to $150 per square foot. 

With both materials, it’s usually more affordable to purchase stones that are readily available in your location. You may need to import other stones, which come at a higher cost.
