"I was desperate. My new stove came 2 days before Thanksgiving and didn't fit, by less than 1/8th inch! Matt came the next morning to shave off the edge of the counter so it would fit. He returned the following week to fill cracks in the granite behind my sink. I have been searching for someone for a year! Very knowledgeable, did a very clean job, including resealing the silicone inside around the sink edges, and was a true gentleman. Well worth the reasonable fee he asked for,"

"Company did a good job last summer with 3 bay windows, so I called them back when the rest of the windows in the house needed to be replaced. On the initial visit, I told the rep that I wanted the same windows as last year. He quickly found the job order and picked up the details of the window make/model/etc without any need for me to reinvent the order. The company had the opportunity to try to upsell me, as I asked them about replacement of the skylight in the bathroom. Refreshingly, they declined to do so and told me that it would be much better to wait until we needed to get the roof re-done, and to do the window at that time. As before, the first guy clearly explained the process: guy 1 to take the order and measure the windows, later follow-up visit from guy 2 to remeasure all the windows carefully before ordering their construction, and then a couple of months later, a follow-up call from their HQ to schedule the install. He gave me an approximate window for this scheduling call. It was a pretty broad time-frame because there had been an unusually large number of people needing custom windows. As before, everything went off exactly as the rep indicated. The install team showed up within a half-hour of the estimated time, and installed 11 windows without taking a break. They removed every scrap of rubbish, vacuumed thoroughly, and left the place as clean as it was when they arrived."

"Ben just installed my granite countertop today and it is beautiful! The quality of their work is apparent. I did lots of research, and Celtic granite was the first to respond with a bid, gave me the lowest price, and had the most color options. Ben stayed in touch with me regularly to answer my questions and talk about my options. He made sure to schedule my template and install as soon as I was ready. I could not be happier with their service and would recommend this company again and again!"

Granite Restoration FAQs, answered by experts

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

In most cases, chipped or cracked granite can be salvaged, but it depends on the size and scope of the damage. For example, a pro can smooth out small chips on the edge with polish pads or an angle grinder, but a crack that runs through the stone's surface has little-to-no chance of being fixed easily.

Use a pH-balanced cleaner, avoid abrasive materials, and reseal porous stones like granite annually to maintain durability.

No, you cannot use vinegar to polish marble. It is too acidic for cleaning or polishing and can etch the surface. Instead, opt for non-acidic cleaners made specifically for marble. Follow the manufacturer’s directions to ensure proper application and to protect the marble. However, a damp mop can be an effective marble cleaner when used appropriately and as long as moisture is immediately soaked up.

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.
