Services
Stone Improvement is the future of natural stone, tile, and grout restoration! We provide the San Francisco, Bay Area with high quality hard surface solutions using the most innovative and eco-friendly products on the market. A list of our services are as follows. The marble polishing service using diamond embedded pads is the only way to remove etch marks and bring back an even sheen to the surface.
Stone Improvement carries premium, low odor, low VOC, solvent and water based, interior/exterior, natural look penetrating sealers for natural stone and grout. These sealants are formulated to provide maximum stain protection and excellent oil and water repellency to a variety of substrates with little or no change in appearance.
Stone Improvement uses a low VOC natural stone floor stripper. After the area is prepped we lay down the stripper and go over the areas with our floor machine equipped with heavy duty stripper pads. This is a wet process so it does not create any dust. After multiple passes with the floor machine we go over the areas with our hard surface extractor.
Stone Improvement provides expert natural stone and ceramic/porcelain tile and grout cleaning service. This service deep cleans the tile and grout, removing dirt, mold, soap scum, and other contaminants from the tile and grout. Our tile and grout cleaning service can restore floors, counter tops, shower stalls, walls lobbies, decks, and more.

This BBB office does not read the communications in the complaints. They consistently side with the business (who pays their salary) and close the case in their favor, even when the facts indicate that the customer has been wronged Most BBB organizations make an attempt to do the right thing. This one will not.

Absolutely pathetic. The rep closed my complaint against Twitter even though it was not clearly resolved. She said it’s because I kept going back and forth. I saw other complaints on the site that went back and forth far beyond mine and nothing was closed in their cases. This BBB branch is a joke.

After the last communication, John did sent back an email stating that he was not available for site visit due to his busy schedule. He did manage to come by and then gave me an estimate for the job. I found him very knowledgeable and pragmatic. He answered all my questions and made useful suggestions. Will have a follow up review if he is hired to do this job,

I recently ordered a sweatshirt from Swagnation under the false pretenses that it would be a Vanson sweatshirt. The picture in the advertisement is a Vanson but this company doesn't sell Vanson. Once I figured this out from researching and discovering that this company was not only not selling what they advertised. But they also were not getting the merchandise out to any of their customers in the timeframe they promised (3-5 weeks). I immediately within two days of ordering tried to contact them to cancel the order and receive a refund. First of all. The e-mail addresses they provided were not

I had my ID stolen in Sept 2016. Because my ID monitoring service caught it quickly, there was little damage done. But the bad guys were able to lease cell phones with SmartPay and my credit monitoring service was completely unable to get SmartPay to understand that the account that was opened in my name was fraudulent. We must have spent 50 hrs on the phone with SmartPay and sending them the documents they wanted over and over again, but they would never close the fraudulent account. This went on for 6 months and was terribly frustrating. Finally it was suggested that we contact the BBB. This

Consummate professionals. John and Josh cleaned and sealed the marble counter tops in our kitchen and the marble walls/floors and limestone floors in our bathrooms. They worked carefully, showing a strong commitment to doing the job properly. In addition, they patiently and thoroughly responded to several questions we had about the process. They also provided valuable advice about how we should care for our stone to keep it looking good. We will definitely turn to them again for all of our stone needs.

I wish all SF tradesmen were as good as John. I had 3 tile kitchen counters and two small bathrooms, all with tired looking grout. John came by to look at the job and give a quote, which I accepted. He came to the job on time and well prepared. He and his helper spent the day going over these 30 year old surfaces. They took their time and did a nice job, making sure to keep my wood floors dry along the way. Very professional and the counters and bathrooms are much improved. He also left some sealer with instructions, so I probably won't need him again (at least for these surfaces) for 40 years

Great Job!! I hired Stone Improvement to clean my front concrete stairs that were all dirty and moss started appearing here and there. The work was done in one morning and now it looks like like completely new stairs. Unbelievable. John was also fast in responding to my emails, easy to schedule, on time and estimate was what we ended up paying. Will definitely hire again.

I recently hired Stone Improvement to clean and seal several sets of outdoor granite stairs at my home. Several of the stairs had tar stains from the underlying waterproofing material that had leaked during last winter's rains and none of the stairs had been sealed or caulked when they were originally installed a year ago. Nick came by the property to give me an accurate estimate and set expectations on what could be done. He and his team exceeded my expectations. The work was done professionally and at each step of the way, Nick provided me with an update on progress as it took several

Huh. We've never had these experiences with the BBB. We've been members for a long time, then we let our membership lapse, then we got back on board... but at no time during any of this were we pestered or coerced. I feel bad that this has happened to some people. It must be frustrating. Yelp, on the other hand, is a horrendous reviewing venue for most small businesses (other than restaurant’s). Since they make it very difficult for known business owners to also write reviews about any other business, I deduce that most reviews one reads are written by people who have never built a business for

I used the BBB twice in the last two years to recoup money from unscrupulous merchants. I truthfully and thoroughly stated my issues, went back and forth for weeks with responses, provided hard evidence, including bills and letters, and got absolutely nothing for my trouble.
One merchant lied repeatedly, submitted falsified documents, committed libel, threatened me with lawsuits, and won her case because she is a BBB member.
The other merchant lied repeatedly to the BBB, told the credit card company that they gave me a non-existent receipt for returned merchandise, and suggested that she would

I had a problem where the marbles had a deep major soap looking like stain engraved into the stone damaged by my previous tenants. They came and estimated the damage, it turned out harder then it looked and they kept working at it and would not stop until it was all fixed! Worked many extra hours on top of there estimate with no complaints. These guys work hard and are of integrity! Everything looks like BRAND NEW now, I love it, saved a lot of money from replacing the entire marble since I have expensive marbles tops! Would highly recommend to anyone both for skill and integrity and kindness

We too have "ancient" tile in our bathroom...1935 builder-grade tile. 70+ years later, the grout was impossible to clean, but the delightfully professional young owners of the company brightened up the tile, made the grout look as good as new. Provided I clean grout and tile as they recommended (no more Tilex), the renewal should last another 15-20 years. They also worked on my remodeled (2005) downstairs bathroom tile. The remodeling crew walked on the tile before the grout was totally dry...then they sealed in the dirt. I didn't notice until it was too late. Stone Improvement

Prior to service from Stone Improvement, my tile floor looked awful; dirty grouts under a stubborn floor sealant which gave the tiles an appearance of discoloration and dilapidation. Nick and John did a great job cleaning the floor and resealing. I was very impressed with their workmanship and professionalism; they were on time and very courteous, answered my questions beyond sufficiency, and serviced the floors to their *clean* original state. John and Nick worked incredibly hard (the floor sealant was very tough to remove) which admittedly necessitates an apology, sorry guys. In addition, the
