Coit Stone Cleaning San Francisco is Proud to Provide these Excellent Services

  • When we’re deep cleaning granite countertops, or any other kind of stone surface you have in your home, our powerful professional equipment will get rid of oil and wax buildup that blocks the stone’s natural shine.
  • Our trained technicians will use the highest quality diamond pads to not only hone the surfaces; we’ll also polish after we remove scratches and any other visible damage.
  • In addition to honing and polishing when we’re performing granite cleaning, marble cleaning or any other kind of treatment, we’ll apply sealers on the surface to act as a shield against future damage.
  • If you have stone surfaces that need professional attention in multiple rooms, not to worry - we work in bathrooms, kitchens, outdoor spaces and anywhere else you need us.
  • Should you encounter stone that’s broken or cracked and you think it’s beyond repair, Coit’s San Francisco team can tackle and restore these issues, thanks to years of expertise.
  • And we don’t just limit our cleaning and restoration services to granite and marble; we also treat Saltillo, travertine, slate, terrazzo and many others.
