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.

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.

Small kitchens benefit from simple, blunt countertop edges, as complicated edges can create visual clutter and be more of a hazard if you bump into them. Eased edges are a top pick for small kitchens because they are simple, do not jut out, and do not take up additional space. Bullnose edge countertops are also popular because of their rounded design; they are elegantly simple and will not be sharp when you bump against them. Single-beveled edges are also a good choice, as they look a little more upscale but still have rounded edges for safety and simplicity.

Countertops typically hang over base cabinets by 1.5 inches. This slight overhang protects cabinet faces from spills and provides a finished look. The overhang may extend 12 inches or more for kitchen islands or breakfast bars to allow for seating and comfortable eating.
