"Love my redone bathrooms. John did two countertops, a fiberglass shower/tub, and my master shower and encased tub. The colors are beautiful. John was very responsive throughout the whole process. Highly recommend saving money this route over a complete remodel."

"Natural Stone Construction did an excellent job with our countertop installation. The entire process was smooth and professional, from the initial measurements to the final installation. The countertops came out beautiful, the cuts and edges were clean, and everything fit perfectly. The team was reliable, knowledgeable, and kept the work area clean. We are extremely happy with the finished kitchen and would definitely recommend Natural Stone Construction to anyone looking for quality countertop fabrication and installation."

"Enrique was my contractor for a full kitchen transformation. Turning a disaster from water damage into a beautiful, upgraded kitchen. His estimate was genuine and transparent from the start and the quality of his work has me already planning to hire him again for future projects. Highly recommended."

Countertops and Backsplashes FAQs, answered by experts

Most recycled glass countertops are nonporous, so they don’t require sealant. There is, however, one major exception. If your recycled glass countertop contains a cement binder, it’ll require an additional layer of protection. Seal these countertops once or twice a year. Use a concrete sealant and finish it with a food-safe wax for a gorgeous and shiny finish. Otherwise, just clean the countertop regularly and always use a cutting board.

Mitered edge countertops are usually 2 to 2.5 inches thick. The thickness accounts for the 45-degree angle required to form a seamless corner, resulting in a dramatic and thick-edged appearance.

Granite countertops can last for 100 years or more with proper maintenance, even in high-traffic areas like kitchens and bathrooms. Granite can crack, stain, or fade over time, like any countertop material, but it’s a highly durable option that should offer a lifetime of use. Some ways to increase the longevity of granite countertops include regularly cleaning the surface, especially after spills, avoiding sharp objects directly on the countertop, and resealing the material every few years.

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.

There are many differences between solid surface and quartz countertops. Whether one is as good as the other will depend on what you value most in a counter. These two materials are nonporous, although quartz is more durable. Some people may prefer the look of quartz, although they’re both available in many different colors and designs.
