Restoration of stone is the restoring of worn granite, marble, travertine, etc. to the state in which it was installed. It occasionally entails the modifying of the stone’s surface to create the desired finish. Occasionally an owner may prefer a polished surface to be honed or visa versa. Here are our stone restoration services:

NATURAL STONE POLISHING:  Light surface scratches and some mild chemical etching can be polished out using a variety of polishing compounds, powders and crystallizers.

Diamond Grinding:  Diamond Grinding is used on natural stone surfaces that are damaged from stains caused by acids drink, food spills, cleaners and excessive wear. Resurfacing brings the deep stone to life and shine, and with the right care and protection, the stone will standout through time.

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

STAIN REMOVAL: Natural surfaces such as stone are permeable and can stain easily if not properly sealed. Identifying the type of stain and selecting the correct chemicals and poultice materials are key 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 team can help you with granite crackand seam repairs. Relax and let the professionals handle it for you.

CATASTROPHIC AND WATER REPAIR: Why replace when you can restore? Unfortunately, people go through the painful time and expense of replacing the stone tile from water and fire damage never realizing that restoration provides a quicker and more affordable choice.

For stains as a result of Moss, Mold, Algae, Mildew, Lichens we use (and recommend) D/2 Biological Solution. Once the surface is cleaned a final application will be added to insure a deep through cleaning and continue to work over time.
