Granite Countertop Badly Damaged

Our San Ramon, CA clients were worried they would have to replace their granite countertop, because it had severe damage as you can see in the BEFORE images. They decided to give us a call for a FREE estimate and to see whether the countertop was salvageable.

The damage was caused by moisture, Tony DeLuna, Owner of Patriot Stone Restoration explained. "First, the caulking broke loose, and then water seeped under the granite, saturating the metal support bar and causing expansion from rust and corrosion."

We told them that the countertop was not merely salvageable but that we could repair it to a like-new condition. After comparing the cost of a new countertop with the cost of repair and viewing a case study of a similar job to see the kind of results they could expect, they asked us to go ahead and do the repairs.

Our Repair Process

The first step in repairing this countertop was to remove pieces of the granite and set them aside for reassembly. After the damaged stone was removed, we removed the rust and corrosion on the support bar and used clear epoxy to seal and water proof the entire substrate, including the wood base.

Then, we reassembled the stone, carefully aligning and leveling each piece to prevent any dips or waves in the finish, and filled in missing sections with tinted epoxy and aggregates that matched the original stone. We gave the countertop plenty of time to dry.

To achieve a uniform, reflective finish, we ground the surface of the countertop flat, power-honed, and polished it using a series of diamond pads with progressively finer grits, and then sealed it to inhibit staining.

Our clients were absolutely stunned at how the repaired granite looked almost identical to the surrounding granite, and they were grateful that we were able to help them avoid paying thousands of dollars more for a replacement countertop.
