"I found 3 Brothers Marble & Granite Fabricators on Google while searching for a company to help with my project, and it ended up being the best decision I could have made. From the beginning, their customer service was excellent. They were very professional, responsive, and took the time to answer all my questions. The team made the entire process smooth and stress-free. The quality of their work is truly impressive. Everything was done with great attention to detail, and the final result was perfect and impeccable. You can tell they take pride in their craftsmanship. Whenever I had a question or needed something, they were always there to help and guide me. It’s not easy to find companies that combine great service with such high-quality work. I highly recommend them to anyone looking for reliable professionals for marble or granite work. I’m extremely happy with the results."

Customers say: Quality work

"We hired Ernest and Sons to construct our patio tiles. We purchased 2' X 2' Tiles and I have to say they did a gorgeous job. I was so pleased with the way they showed up when they said they would. The men that laid out on my job worked so hard. The labor was very strenuous but they never took a break. They were the most conscientious and polite workers I've ever dealt with. They worked neatly, cleaned up totally afterward, and just had a great deal of respect for our property. They really did a beautiful job and Ernest, the owner is a real gentleman also. Love this company!"

"Danny and his team are the best. His prices are reasonable. He is very honest. He starts his jobs very early, he explains the work that will be done, he is very particular and detail oriented. He makes sure that the job is done correctly. Danny has extensive knowledge about homes. He replaced a leaking pipe that lead to the roof in my attic, installed plywood in my attic for storage, repaired a leak in my roof, replaced shingles on the roof, installed ceiling storage racks and shelving in my garage and he shows you different aspects of the job as he is working on it. . Everything was done perfectly and he cleaned up when he was finished. There is nothing that he cannot do. And most of all, he is a very nice and courteous person. I will be contacting him again for additional projects."

Countertops and Backsplashes FAQs, answered by experts

Durable, contemporary concrete countertops can increase home values. However, they might not offer as high an ROI as quartz or granite surfaces, which offer a timeless aesthetic and durability likely to appeal to a range of home buyers. Installing new countertops is a home improvement that can yield an average of 60% to 80% ROI when done well, using quality, perennially popular materials.

Both quartz and granite are durable, long-lasting countertop materials that can last for decades, potentially the lifetime of your kitchen, with proper maintenance. Quartz is generally considered more durable than granite due to its nonporous nature. However, it can be damaged by extreme heat. Granite is also very durable but is a porous material that requires regular resealing to extend its lifespan and prevent stains. On the other hand, granite is more resistant to heat than quartz.

Yes, you can generally put hot pans directly on a granite countertop without worrying about cracking, as it is a durable, heat-resistant stone that can withstand high temperatures. However, it is still highly recommended to use a trivet or hot pad as a precaution. Prolonged or repeated exposure to high heat can potentially cause discoloration or damage the countertop's sealant, making it more susceptible to staining. Additionally, the heat from a pan can transfer to the granite, creating a burn hazard for anyone who touches the surface shortly after.

Resurfacing countertops is relatively easy—especially for a pro. During this process, a countertop contractor will sand down or remove the existing countertop surface, make repairs, and then add a new surface or special coating. In certain instances, like if you use a laminate countertop coating system, it’s an attainable DIY for beginners.

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.
