Countertops and Backsplashes FAQs, answered by experts

Since knowing how to install countertops correctly requires in-depth knowledge and understanding of the topic, we recommend hiring a professional countertops installer near you to work on this project. Kitchen countertops are a high-visibility investment, meaning mistakes made during DIY installation will be easy to spot, may cause damage, and potentially require re-purchasing materials. Professional countertop installers have the skills, tools, and experience to place your new kitchen feature safely and correctly.

The average countertop square footage in a kitchen is 30 square feet, but that number varies widely depending on the size of the kitchen. Some smaller kitchens may only have one stretch of countertop or an L-shape. Larger kitchens can include an island or peninsula and more expansive countertops. When deciding what works best for your home, measure your kitchen countertop and make sure to include countertop cost calculations in your budget.

Engineered stone countertops range in price between $60 and $200 per square foot. The three main types are quartz, recycled glass, and sintered stone. The most affordable is sintered stone, which is ideal for outdoor kitchens and costs $60 to $100 per square foot.

Recycled glass countertops fall in the middle at $65 to $140 per square foot and offer a very distinct look. Meanwhile, quartz counters are on the higher end of the price range at $50 to $200 per square foot. Popular quartz options mimic the look of natural stones like marble and granite.

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.

You can resurface existing countertops as long as they’re not significantly damaged. Of course, it does depend on the material. Wood, natural stone, quartz, and even laminate are all good candidates for resurfacing. If you have tile, you may want to just replace the damaged tiles rather than resurface the entire countertop.
