House cleaners used acid on this travertine stone tile causing etching (looks like staining from a spill)

We cleaned the floor, honed it to remove the damage & sealed the stone and grout to make it look like new.

Honed half of this piece granite to show a potential client what their countertops could look like. The installation shop referred us to them & had this piece. They have a glare because of the windows and lighting that they're hoping honing will eliminate.

What hardwater is doing to peoples shower glass is wrong. Consumers spend good money on shower glass and within a few years the glass looks like a sheet of fog rolled up into their bathroom. Then starts the purchasing of multiple products and lots of scrubbing to try to get their shower glass l...

Stripping a poorly applied colorseal product from a commercial bathroom floor in Bellevue Washington this past Saturday.

We went to Mercer Island on Monday to remove etching caused by a house cleaning company who accidentally used an acidic product on the travertine floor. We were able to "hone" the stone with diamond resin abrasives and take the stone back to a polish, restoring the sign.

Extremely bad calcium build up on this travertine stone shower pan in Woodinville. We did a lot of grinding and re-grouting to restore this as close to "like new" as possible as well as steam cleaning and sealing the stone and polishing and sealing the shower glass.

Mike and his team are highly professional, knowledgeable, and take a great deal of pride in their workmanship. When we bought our new construction home, 12 years ago, we didn’t realize the granite kitchen counters and large island, as well as our marble bar top were never sealed. Over the years, hard water and daily cleaning took its toll and our solid surfaces looked drab and dingy. We also had a glass ring and other discoloration on the marble bar top. Chuck and Matt worked meticulously to remove all the stains as well as clean the grout. They then sealed and polished the surfaces, making them look and feel better than new. It’s so nice to have beautiful, shiny surfaces that clean up easily. Great care was taken to ensure no damage was done to surrounding areas. They explained their process and answered our questions. We highly recommend Mike and his team and will have them back for future projects.

They just finished restoring my white marble shower and mosaic floor and also polished the hard water spots off of my shower glass. I am prepping my home for sale and now all my marble looks like new.
