"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

Granite Restoration FAQs, answered by experts

While DIY kits are available for minor stone polishing, larger restoration projects benefit from professional expertise. A professional can ensure an even, high-quality finish, handle stain removal, apply proper sealing for long-lasting protection, and guarantee the work's durability.

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.

While no countertop material is truly “heatproof,” granite countertops are extremely resistant to high temperatures. Some types of granite can withstand temperatures up to 1,200 degrees Fahrenheit. However, we don’t recommend placing hot pots and pans directly on granite countertops. Even if it doesn’t scar the granite, it may damage the sealant.

The time required for stone restoration or polishing can range from a few hours to several days. Most standard jobs are completed in 4-8 hours. The final duration depends on factors like the size of the area, the condition of the stone, and accessibility. Larger areas or surfaces with heavy damage may require multiple sessions to complete.

You generally cannot change the color of the natural stone, such as making granite countertops darker or lighter. Some people claim that certain chemicals will lighten or darken granite, but those will damage the stone and not provide uniform, expected results, so it’s better not to try. Similarly, some people ask whether they can stain over granite. Granite is beloved for its stain-resistant finish, so you probably won’t get the best outcome if you try to stain over granite to make it darker.

Instead, consider honing, painting, or applying another material over the top of the granite to make it appear darker.
