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!"

"Noel of Don Webb was a pleasure to work with in our project of installing custom countoured shape granite countertops and glass backspash tiles. He is extremely easy to work with, and can quickly overcome any obstacles which may arise from ongoing custimization during the course of the project implementation. He and his crew work quickly, efficiently and to perfection. His prices are very competitive and his work is perfect. I highly recommend him to anyone wanting to upgrade their kitchen. No, I am not a relative. Elliot Y Merkin, Springfield NJ"

"We had an excellent experience from beginning to end.  We worked with Fernando and was very impressed with the professionalism by him and his workers.  They even did some extra work (sealing) on another stone countertop that we already and did not charge.  I would definitely use them again and recommend them to anyone who is looking for a thorough job, fair price, and professionalism from beginning to end.

Countertops and Backsplashes FAQs, answered by experts

Most recycled glass countertops are nonporous, so they don’t require sealant. There is, however, one major exception. If your recycled glass countertop contains a cement binder, it’ll require an additional layer of protection. Seal these countertops once or twice a year. Use a concrete sealant and finish it with a food-safe wax for a gorgeous and shiny finish. Otherwise, just clean the countertop regularly and always use a cutting board.

Costs depend on material quality, labor rates, and additional features like integrated backsplashes.

The easiest way to calculate a countertop's square footage is to divide your countertop into squares and rectangles, then multiply the length and the width of each piece in inches before adding them together and dividing by 144.

Rounded countertop edges, like bullnose or eased edges, are the least likely to chip. Their smooth, curved design helps distribute impact more evenly, unlike sharp corners, which often take the brunt of a hit. Also, unlike pointed edges, rounded edges won't snag on material like dishcloths or clothing.

Porcelain is a relatively affordable, mid-range countertop material. It typically costs between $50 to $70 per square foot.

Compared to quartz, porcelain is slightly more affordable, as quartz generally ranges from $50 to $200 per square foot. However, lower-quality, builder's grade quartz can be similar in price to porcelain.

Compared to granite, the price can be similar, depending on the quality of the stone. While granite slabs can range from $50 to $200 per square foot, you can find lower-end granite in the same price range as porcelain. High-end granites will cost significantly more.

Porcelain is generally more expensive than laminate, acrylic, and ceramic, but less expensive than high-end slate, concrete, and marble. A key benefit is that porcelain does not require sealing, which reduces long-term maintenance costs.
