Natural stone can be worn down over the years. We offer a complete set of Natural Stone Restoration services designed to restore stone to its original beauty. Polishing, Refinishing and Cleaning can be carried out on all limestone, terrazzo, slate, marble, granite and other natural stone surfaces. Are you looking for a different look? You can change the look of any area where stone is installed, by honing your stone which leaves natural stone surfaces with a flat matte finish.


We can shield your stone's surface from moisture and aging with our natural stone sealing solutions. If you want to have your stone appear as if it was just installed, then sealers can be used to prevent staining and water damage.


In order to avoid expensive repairs in the future, you should have scheduled maintenance performed on your natural stone. Regularly planned sealing and cleaning can save you money in the long run by avoiding preventable damage which could result in expensive repairs. If you want to ensure that you natural stone always looks its best then let Dave The Marble Guy customize a maintenance plan just for you.

Restoration of stone is the reviving of worn out stone– marble, travertine, granite, 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:

Light surface scratches and some mild chemical etching can be polished out using different polishing compounds, powders and crystallizers.

Diamond Grinding:
Dave The Grout Guy prefers a natural finish and tries to avoid using waxes or other surface coatings on polished stone, but achieves a high gloss finish with his diamond grinding process.

UNEVEN TILE REPAIR & LIPPAGE REMOVAL: Low-quality installations can be a prevalent problem with uneven tile. It can take away from the beauty of the natural stone as well as presenting a serious safety hazard. StoneCare of Texas can provide many levels of lippage removal.

STAIN REMOVAL: Hard surfaces like natural stone, concrete, terrazzo, and specific kinds of tile, in addition to the grout lines in between tile, are porous, meaning that they will absorb liquids. If such liquids happen to be staining agents, a stain will develop. Stain removal methods will vary, depending on the type of stain.

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 the professionals take care of it for you.

CATASTROPHIC AND WATER DAMAGE REPAIR: Restore, don’t replace! Unfortunately, people often go through the painful time and expenses of replacing the stone tile from flood and fire damage without realizing that restoration provides a cheaper and faster option.
