"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."

"Joshua is great! I purchased the toilets at Home Depot and arranged for Joshua to pick them up. Well HD Lancaster location only had two of the HE toilets that I wanted, so the 3rd toilet was picked up in the HD Palmdale store. Joshua did all this with pleasure. He was on time, work was completed superbly and cleanup was on point. I will always call on Joshua for my Handyman needs..."

Granite Restoration FAQs, answered by experts

Both buffing and polishing increase the longevity of your floors by removing scratches and buildup, but they are different processes. Polishing removes the top layer of your floor, removing surface-level scuffs and scratches. Buffing your floor involves filling the scratches and scuffs with a buffing solution. No matter which method you choose, you can rest assured that both techniques will leave your floor looking shiny and new.  

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.

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.

The best cleaning method to use for your project will depend on the specifics of that project. However, sandblasting does come with the risk of damaging the surface you’re trying to clean. One safer alternative to sandblasting is laser cleaning, which can remove many of the same contaminants with a lower risk of damage and a lower overall cost.
