Stone Restoration is the art and science of restoring natural stone floors and surfaces to their original beauty. It is our job to restore your stone back to its original beauty using one or more of the following services:

A Polished Finish has a sleek look and creates a deep color on natural stone. It is typically used on counter tops and floors to protect them from daily wear and possible damage occurrence. Polishing technique to be used, will be determined by expert on site.

Diamond Grinding:
Dave The Grout Guy prefers a natural finish and does not use waxes or other surface coatings on polished stone, but achieves a high gloss finish with his diamond grinding process.

UNEVEN TILE REPAIR & LIPPAGE REMOVAL: It is a procedure where unleveled surfaces between tile edges are removed evenly to flatten them and leave them with a smooth surface to the touch

NATURAL STONE STAIN REMOVAL: Natural surfaces such as stone are permeable and can stain easily if not properly sealed. Pinpointing the stain type and choosing the correct chemicals and poultice materials are critical to stain elimination.

GRANITE CRACK & SEAM REPAIR: If a DIY repair kit for your granite counter tops isn't something you want to mess with, Dave’s crew can help you with crack and seam repairs. Take it easy and let our team deal with it for you.

CATASTROPHIC AND WATER REPAIR: Restore, don’t replace! Unfortunately, people often go through the painful time and expenses of replacing the stone tile from water and fire damage without even realizing that restoration provides a quicker and more affordable alternative.
