    Grout before was very dark after 14 years (isn't my dog adorable?)
    Gina M.

    To set the scene...I've had my tile for 14 years. In that time, I had never Had it re-sealed. Clearly, in that time, it didn't retain its color, and, in an attempt to restore its original color, I did have it professionally steam cleaned several years ago by a different company. It pretty much looked the same as before they started, and they claimed that some of the grout just couldn't be cleaned to the original color (kitchen, high traffic area) but that they could paint the grout in my downstairs for $1200. I told them thanks, but no thanks. I recently called Grout Doctor to see if there was anything they could do to refresh my grout because I really was sick of having almost black grout in my kitchen. I quickly got a call back, and within a day or two, someone was at the house to give me an estimate. They quoted me $600 to clean, paint and reseal my grout on the entire downstairs floors as well as the floors and tile counters in my upstairs hall & master baths, PLUS they'd re-caulk around my sinks and toilets in all three bathrooms. I'm not sure how many square feet of tile there is, but probably about 1100 sf of tile. L I was a little nervous because I'd seen painted grout before and I didn't like the look. Something had to give though, and since it was half of what the last person quoted and they were doing much more, I figured I'd give it a shot. They came, blazed through the job and left my tile looking brand new. I honestly can't even believe how great it looks. They did an AWESOME job, they were quick and efficient, and their price was great. So impressed and highly recommend. Don't let the cheesy name fool you!

    Cracked grout that was replaced only 5 months ago

    Martin seemed like a trustworthy and reliable professional but 5 months later, we are disappointed in the work that was done. Martin had mentioned that 90% of his business is from realtors which probably should have been a red flag as our grout looked great initially but the recoloring is now coming off even after he sealed it and the grout that was fixed/replaced is already cracking. I texted Martin to see what can be done and received no response.

    Before. Note Crack all along the seam.

    Phenomenal Job!!! My Kitchen looks brand new. Martin replied to my Yelp request promptly, came right away and knew just what had to be done. Wilmur came out ...the very next day mind you ... cleaned, repaired and sealed our Kitchen. We couldn't be happier with the level of detail and professionalism. No need to look any further if you need Grout Repair, Martin is your Guy! I should mention, at first we only wanted the leaking Sink done, but it turned out getting the whole counter done was so affordable we couldn't pass it up. No hard sales, just information.

    Martin came highly recommended and now I know why. He was friendly and offered various options I could go with in my bathroom. Didn't pressure me, just gave me his expert opinion and let me think about it. The price was great and was able to fit me in his schedule within a week. The team got here on time, worked efficiently and I was so impressed with what they accomplished. Would recommend to anyone who is in need of grout work. Wish I had a before picture. Trust me it was bad. But look at the after. Trying to think of a reason to have people over so they can see the bathroom; lol.

    My shower before the Grout Doctor.

    I was doing a small update of my bathroom, and my contractor suggested I contact the Grout Doctor at 925-866-0853 to refresh my shower. Well. You can see from these before and after pictures how beautifully my shower turned out as a result. It feels like a spa now! I also had my tile floors and kitchen sink grout replaced/refreshed. I'm SO pleased with the result! Highly recommend.

    Countertop after!
    Sarah M.

    They did a fantastic job on our kitchen grout! Cleaned, repaired, and sealed. We have a tile kitchen countertop that hasn't been updated since the house was built in 1985. Martin was very quick to respond to my voicemail and came over right away to give me a quote. I forget the gentleman's name that did the job (Marvin, maybe?) but he did awesome! Was here from 9-12:30 and our kitchen looks new!!

    The grout doctor guys are the best did a great job
    Javier H.

    I had coit do the last time they did a terrible job I don't recommend them to clean tile I called the grout doctor this time they were fantastic very good job he works real clean too no mess and gos the extra mile he was just great it looks brand new the grout color he chose is perfect sealed and wow brand new I would definitely recommend them

    Great fast service, next day!! We needed the grout repaired in preparation to sell the home. The new grout came out perfectly and really make the kitchen "pop".

    What the Grout Doctor can do!!! Thrilled!!!
    Caroline P.

    Thank you, Martin for transforming our kitchen. It's a great budget friendly solution for those who have old grout. I was bothered by the dark grout tile kitchen countertop of our new house. I currently don't have the budget to do much updates but I couldn't live with the dark grout as it looked very unsanitary. Martin met us on a Sunday and gave a us a quick, reasonable quote. Posted a photo...I guess that says it all. The kitchen looks so much cleaner! Thank you, Martin!!

He cleaned the tile thoroughly, sealed the grout, and protected everything so well. The floors looked absolutely beautiful when the job was done. After a long and stressful day at work, coming home and seeing everything so clean truly made my day. It made me smile. I really cannot express how happy I was with the results, especially knowing Wilbur handled everything by himself. You will absolutely get your money's worth with this company. The cost was very affordable, and the quality of work was outstanding. Wilbur was professional, kind, on time, and did exactly what he promised. I was given the quote over the phone, the process was easy, and he came in and got the job done. Even though I wasn't home when he finished, his work spoke for itself. I almost wanted to keep this company to myself, but Wilbur deserves the recognition and more customers because he truly does outstanding work. I am beyond thankful and would recommend this company 110%. Thank you so much Wilbur!! Your professionalism, hard work and attention to detail really show, and you truly made me happy.

Noe…read moregave a prompt response and scheduled me within a couple weeks for shower grout and floor grout. Noe and Maria arrived on time and did a beautiful job on the shower regrout and Noe even accommodated some last minute requests to add caulking in the kitchen and quarter round. Unfortunately, we had different ideas about what grout 'touch-ups' meant for the floors - I wanted a few spots regrouted to match the rest of the flooring's grout color - but it really lacked a professional touch and didn't look good at all. I did invite Noe to come back to redo it, and it still did not meet the professional standard I paid for. I would have appreciated more thorough communication from the start to make sure I was getting what I needed. To be honest, this was not the cheapest quote I got but paid more because of the great reviews. I would be happy to change my review to 5 stars if the team wants to come back for a full regrout on the floors, but I'm not planning to pay any more than I already have. I'll attach some pictures of the beautiful shower and subpar floor grout job.

He did a seal and when the rain came and went the leak did not happen! Now we know where to address when we have more time and sunshine. Also had him check out my front steps that seem to need to be re-grouted - he pointed out white water marks coming out from the tiles is a sign of water getting in behind so he went tile by tile to figure out how many are loose. I look forward to his bid for service for spring project as he does great work so I feel like I will get a good deal and a great job well done.

From the very start, the experience was seamless. I left a voicemail and by the next day, we were already scheduled for a free inspection and consultation. He was even flexible enough to come out on a weekend, which I truly appreciated. During the walkthrough, Michal was prompt and walked us through exactly how he could revitalize and restore our bathrooms. The administrative side was just as impressive. He sent over a thorough invoice quickly and was very responsive to my follow-up questions via email. Once we approved the invoice, he offered multiple scheduling options, making the whole process stress-free. On the day of the project, Michal showed up right on time. He demonstrated great professionalism by covering all the walkways with painters' cloths before jumping right into the work. What really stood out to me was that he remembered every single detail we had discussed weeks prior--it's clear he puts immense care and attention into his clients' specific needs. After two days of work, the transformation is night and day! Our showers and sinks look brand new. His grout and caulking work is perfect; you can tell how meticulous he is from start to finish. We are already planning to have him back to finish our final bathroom once our other construction is complete. Bottom line: If you want high-quality restoration and a stress-free experience, call Michal!

    I do not like giving bad reviews but this guy was so unconcerned about our satisfaction with the…read morejob, and left the floor in such terrible shape, that I want to comment. The reason I am still bothered, although this was months ago now, is that he tried to gaslight both my husband and me and was very forceful with his tone of voice and language trying to convince us of things we could see were not true (neither my husband nor I are overly emotional). When we showed him the mismatched grout colors (described below) he would say they matched. But clearly they didn't. Then he would say they would dry to match. They didn't. And he repeatedly would argue like this about the very thing we could see in front of us telling us what we saw was not true, mismatched grout. He did this when he could not remove all of the white finish from the grout leaving some white spots in the grey grout, in the places where it was hardest to reach. He tried twice to remove the white from the hard to reach spots, and he said he could not. I want to say at this point he was very angry and did offer me a refund, and I suggested it felt unfair to not pay him at all (we have a strong sense of what is fair, and money is not our main concern, and they had spent hours, but with his attitude I should have taken the refund!). Instead I asked him to just come back and fix the grout and we'd call it even. When he came back, without asking me applied black grout colorant over the white spots, this time telling us the black was the same color as the grey grout. Clearly it was not, yet he argued the point that it was. He kept saying "this is the right color". Then he said in a year it might change to grey!!! (By the way, this was new tile that had the wrong finish on it, which is why we called him in... no way was the grout grey because it faded over time, it was always grey). When I saw this was going to be left mismatched, I asked him to just use the colorant over all the grout, leaving it all one color (I prefer grey but all one color was my priority). He said "We don't do that". Clearly they do! He had just done that to spots of the grout. Then, gaslighting us again, he again said that it matched (clearly it did not, it was high contrast to the grey grout) and then he said again that it would dry to match. Of course it did not. When he left this time, and he said when it dried it would turn grey, I don't know why I believed him, I think I was just exhausted by all of this. The same line had never been true before, but in the the exchanges with him he became so heated I just wanted him gone. So I thanked him and let him leave. And he left a job done horribly. No one would have been happy with that floor. I ended up hiring another company to recolor the grout and am very happy with the results. So it cost me twice as much in the end, but the guy I found was so very nice. He actually cared whether or not I was happy with the floor!!!! I clearly wasted my money, energy and time on this very rude man. NOTE: There is more to this story, when he first did the floor he did not do inside the closet, even though it is the same floor. Then when it looked different inside the closet he tried to tell me they used a different sealer in the closet area. I knew they had not, but he insisted it was their fault not his. He did, however, finally do the floor after spending much time trying to tell me it could not be done. For the hard to reach areas that were still white, I even offered that if he would tell me what to use I would clean the hard to reach spots myself but he said it's a "trade secret" and wouldn't advice me how to do it myself. He originally gave us a quote to clean the finish off our tiles, and to replace the grout. When he got there he decided just to clean the grout and not replace. Fine with me. But when he did the job, leaving several white spots where the finish was more stubborn he vehemently tried to tell me it wasn't white. I could see it was. My husband could see it was. Guests who came later could see it was. It made us feel crazy. He came back, begrudgingly and tried again, but still did not get the white off. Finally he used colorant over the white, but it was black, leaving the floor just as messed up as if it were white areas. I have attached photos of the white and black grout that he left me with, each time considering the job done. He did a terrible job but worse... he was so rude about it.

    We wanted to have our pool tile cleaned and regrouted so I called a few of the grout companies I…read morefound on Yelp. Thomas responded right away and asked me to send him a video of the pool area. He said he would come the next day to take a look and give me a quote. He showed up on time and gave me a reasonable quote. In the meanwhile, I tried to call two other grout companies that both asked me to send them a video too. One followed up via text but once I started asking questions about insurance he stopped responding. The other never responded after receiving the video, so I was going to go with Thomas. I saw the recent one star review that was posted and I was concerned. I know things can go wrong with a job, but it's how a company responds to issues that tells me whether I should go with them. The review definitely gave me pause, but there were other good reviews for Thomas and his crew so I set up a time for him to come and do the work. To make sure there would be no unpleasant surprises, I asked clarifying questions about the work, his insurance, and his satisfaction guarantee. He answered everything I asked. On the day before the job was to start, we confirmed the time and he and his crew showed up on the dot. They hand scraped the tiles and reapplied the grout. I appreciated that they did not use chemicals. The reason why I gave four stars instead of five is because I specifically asked Thomas if we should start to drain the pool so they could work on the tile when they got here. He told me they would handle it. The draining process was going slow and his guys couldn't do anything until the level of the pool water was below the tile. Thomas finally suggested getting a sump pump to make the pool drain faster, but he had to drive a distance to get one. As a result, his workers were waiting around until he got back. I wish he would have come prepared with the sump pump, especially since I had asked about draining the pool beforehand. His workers did a good job, but the next day we saw that there was still some white staining on a couple of tiles that got missed so I texted Thomas. He said he would come the next day to check it out. He came and took care of it himself and then had us look everything over to make sure we were satisfied. We were.
