"Work that is beyond my expectations! I had chips along the edges of my coutertop. Bryan was able to fill those with matching epoxy and sand it to create a smooth surface and I was stunned by the result (See before and after pictures below). He also applied silicone under my sink to keep water out. Bryan was courteous, honest, and very professional, and I would highly recommand his company A1 Stone Care to anyone who is looking for that type of work. He also offered and after-service care if chips didn?t hold the test of time, as a proof of guarantee. The apoxy looks very solid to me and now I can enjoy a brand new countertop! Many thanks Bryan!"

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

Countertops and Backsplashes FAQs, answered by experts

Deciding between marble and granite for kitchen countertops depends on your personal priorities, budget, and style. Both materials have similar costs for material and installation.

Marble offers a luxurious aesthetic and timeless beauty, but it is more expensive and requires more maintenance. It is susceptible to staining and etching from acidic substances like coffee, wine, or tomato sauce if spills are not cleaned up quickly.

Granite is highly durable, heat-resistant, and easier to maintain, making it a practical choice for busy kitchens.

Both materials should be sealed to protect against damage, but they can still be vulnerable to stains if spills are left on the surface for too long.

Yes, a 12-inch countertop overhang will need support to keep it stable. The exact type of support depends on your countertop thickness and material. Thicker, heavier countertops need extra support, like a corbel or a post, to keep them from sagging or toppling over.

The minimum counter depth for a kitchen island is around the same as for a standard kitchen countertop, which is around 25 to 26 inches. This depth allows adequate room for food preparation, dining, and working on the island. However, as with other kitchen countertops, depth can vary based on specific needs and preferences in your household.

Quartzite is more expensive than granite, largely because of its rarity. Granite is naturally more common. A granite slab generally costs $40 to $60 per square foot (excluding super-rare types), while quartzite slabs cost anywhere from $50 to $150 per square foot. 

With both materials, it’s usually more affordable to purchase stones that are readily available in your location. You may need to import other stones, which come at a higher cost.

Most homebuyers value standard counter height (34–36 inches) over bar height (40–42 inches).
