"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..."

"Great example of how a contractor experience should be with each and every one of their clients. This contractor was prompt at initial meeting, followed through on the work agreed to complete, and left the job in perfect condition. Installed new pad, stretched carpet, fixed threshold moldings, removed small are of hardwood flooring and replaced with new, installed new baseboards. Highly recommend this contractor.

Granite Restoration FAQs, answered by experts

Standing water can lead to surface discoloration if your granite countertops are improperly sealed. However, it’s possible to remove hard water stains with a baking soda paste. Take more care with acidic liquids, such as fruit juice or red wine, which can leave more permanent stains. That’s why it’s so important to reseal these surfaces regularly.

Professionals remove scratches, stains, and etching, restoring the stone’s natural shine and extending its lifespan.

Stone restoration and polishing enhance the beauty and longevity of stone surfaces by repairing damage and restoring their original shine and functionality.

Yes, baking soda does shine marble. Sprinkle it directly on the marble and let it sit for about five minutes, then wipe it clean with a damp microfiber cloth. If you’d like to make a baking soda paste, then simply mix the baking soda with equal parts water and apply it. You can also add baking soda and dishwashing liquid to a bucket of warm water and mop a marble surface.

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.
