Best marble and granite pros near Laurel, MS

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.

It typically costs $1.25 to $4 per linear foot to repair a granite countertop seam, though the costs will vary depending on whether you do it yourself or hire a pro. The costs will also depend on the extent of the seam and whether your countertops have any additional issues. Granite countertop repairs cost $200 to $1,200, depending on the problem.

Marble is a porous natural stone that needs sealant to minimize staining. Leaving this type of countertop material sealant-free means any liquids left on the surface will quickly absorb into the stone, discoloring it and dulling the sheen. Dark or acidic liquids, like red wine, coffee, and lemon, are the worst culprits. 

Yes, you can repair a stone countertop yourself for minor issues like small chips or scratches, and DIY repair kits are available for this purpose. However, for larger problems such as major cracks or significant stains, DIY repairs may not be effective. In these cases, professional services are recommended to ensure a seamless finish, prevent further damage, and use the proper materials and techniques for a full restoration.
