Before I deleted my original yelp account I was the first to review Sal and Rainbow Terrazzo. I gave him five stars in 2008 and in 2023 he is still 5 stars. Rainbow terrazzo has worked on both my houses in San Francisco and done amazing clean pristine work. I trust him so much that when I moved to Denver I called Sal to repair clean and seal one of the properties Sal is so reliable and dependable I did not have to be present. Highly Highly recommend his work Look at his yelp rating its true read more

Rainbow Terrazzo - Front stairs: cracks repaired, cleaned, and sealed - General Contractors Near Me - San Francisco, California

Sal and his team made our stairs look brand new. Our Sunset home had several cracked stairs that were leaking water underneath the house. We solicited several quotes and his was the best priced and most honest (others tried to upsell us on replacements). Sal's team finished all the stairs, repaired the cracks, and matched the existing terrazzo color and finish perfectly. The final product quality, service, and professionalism were all top-tier! We couldn't recommend Rainbow Terrazzo more highly. read more

Unlike other reviews, my family's experience with Rainbow Terrazzo was far from pleasant. Initially, I tried calling them numerous times to schedule an estimate for my relative's exterior, terrazzo stairs that had water damage and were beginning to sink. Absolutely no one answered or returned my calls. The following week, someone with their business finally followed up and scheduled a date to look at the stairs. The gentleman came out to meet my relative and assured he would send a written estimate in "a few days." Days and days went by with zero communication from Rainbow Terrazzo or any formal estimate. My relative then followed up with the company. They told her that another contractor associated with her number had called in, saying they had the job, and essentially refusing to give a written estimate. This was all very strange and didn't make any sense, since we only received an estimate from one other company and did not give the job to anyone... My sister decided to call the company to clarify directly. She spoke with Manuel who had the same story about this other contractor, yet refusing to share this person's name. He was incredibly dismissive, defensive, and rude with my sister- brushing off her questions as to when we would receive an estimate of any kind and trying to end the call as quickly as possible. This all seemed incredibly off-base. Either- Rainbow Terrazzo simply didn't want the job due to the condition of the stairs and their required work, refused to say that outright, and fabricated a story in its place... Or, someone did call them with this false claim, trying to sub out the job for their own personal gain, and Rainbow Terrazzo openly disregarded the actual homeowner's side and went with this other, random contractors position. Either way, it was very shady and off-putting. Instead of believing the actual word of the homeowner, Manuel took the position of some nameless, outside party with no basis. Safe to say, we wouldn't choose to give any business to this company at this point and will not be choosing to work with them in the future. It was outright disrespectful and a total waste of time all around. I can't speak to the work that Rainbow Terrazzo does, but this experience clearly shows how mismanaged and unprofessional this company is. They do not communicate openly, believe or make up blatant lies, and somehow think it's okay to speak to you in a rude manner. Exterior stair maintenance and repair is common in SF Sunset homes. There are plenty of other people to call. Don't waste your time here. read more

Sal was a pleasure to work with. Competitive pricing and excellent workmanship. He is such a gem.

Rainbow Terrazzo is awesome! With the rain my stairs started to show signs of a leak.. I called Sal, he gave me an estimate and set a date to start the job.. His crew was very professional and refinished the Terrazzo stairs, fixed cracks that had been causing a leak and sealed the the entire stairs.. UNDER the stairs he added support, scraped the loose cement and stucco plastered the entire area.. Now the stairs look good as new! He adds a special Terrazzo sealer that brings out the beauty of the stairs.. If you have terrazzo stairs and need work do not hesitate to Call Sal at Rainbow Terrazzo he is very knowledgeable and friendly.. read more

I have one of those giant panoramic windows and it is pretty cool watching the big ferocious rains come through. What was not cool was watching it rain in my closet. My closet is located under my exterior front stairs which has been neglected for many years. Embarrassing layers of dirt, loose caulk, and cracks made it their home. I even had some cute little baby trees sprouting out the corners of my stairs. This was not good. And the closet was not happy being leaked on. I interviewed four contractors and they all said the same thing. Tear down the stairs and build new stairs. The estimates for this work were set to the tune of $30k - $70k. Now each time it rained, I felt a sudden pang of fear. I don't know about you, but do people actually have this much money sitting around in an emergency stairway fund? One of the contractors mentioned that I have terrazzo stairs and it is very common for them to leak. All I heard was the magic word, "terrazzo." I went into Google research mode, plugged in the magic word into Yelp and found Rainbow Terrazzo! And in enters Sal. He patiently answered all my questions and gave me a good overview of the work to be done. I did not need to have a stairway fund to work with Rainbow Terrazzo because Sal's proposal was not in the quintuple digits of dollars. He is very busy, but was able to fit me in before he goes on his well deserved vacation. He even moved the schedule to an earlier date because he saw rain was coming. The team was punctual and cleaned up after themselves each day. After two days, my stairs were cleaned, grinded, caulked, sealed, and refinished to like new. With a five year warranty, I am so happy that I don't have to fear the rain. An hour after Rainbow Terrazzo left, I already got my first compliment on my new looking stairs by my mail carrier. After living in my home for 12 years, I had to face that parts of my home was falling apart. I was very worried about the costs and Sal offered me some good advice and recommendations that made me feel better. He is a friendly, caring, honest person and takes pride in his work. I talked to over 20 different contractors since last August trying to fix and paint my house and Sal is by far the best one of them all. Thank you so much to Sal, his wife Margot, and the Rainbow Terrazzo team for doing such a fantastic job refinishing my stairs. Highly recommended! read more

Fellow Yelper "G-Man" writes: Hi Rich, Boy, I tell you, that was the best ever yelp review from you for Sal. Just an all around good guy. He did come back to check out the work and it turns out that the additional leaks were caused from some cracks in the siding of the house that I didn't think about. Not only did he help me seal them up, he added another coat on the stairs for free. I need to update my review on him - very impressive! :). Please reachout to Sal @ Rainbow Terrazzo - he's a Trusted Local Business! :) read more

If you are looking for a an excellent terrazzo company to repair and refinish your terrazzo, look no further than Rainbow Terrazzo here in San Francisco! My terrazzo stairs were in complete shambles, so much so that I couldn't even sleep at night! I had other Terrazzo companies come out and look, and being on a fixed income, there was no way that I could afford the quotes that were given to me! After reading all the five star reviews, I had Sal come out and he quoted the very best price! He and his great crew came out the following Monday and started work, and by the end of the week my stairs were beautifully restored to like new condition! My only regret was that I waited so long, and lost so much sleep worrying that someone was going to get hurt on my stairs! Sal is a great guy with a bubbling personality, a ton of experience, and very meticulous! I not only found a great craftsman, but even made a new friend! His crew did a beautiful job, cleaned everything up at the end of each day, and I can't even tell you how thrilled I am to have found him! No doubt about it, he's the man! I even met his lovely wife! What beautiful honest people! Give them a call if you need terrazzo work, you will not be disappointed, I guarantee it! read more

I got three bids and went with Rainbow even though they weren't the cheapest (also not the most expensive). They refinished my faded, cracked and chipped 100+ year old entry stairs and did great work in a timely manner. The stairs look beautiful and I'm so glad I finally had this work done! Thank you Sal! read more

Sal and team fixed our terrazzo steps, including reinforcing the steps from below. I am very pleased with the job. The work was well done. If you look closely, you can see where the patches were made though it is pretty seamless. Key points: - Sal is a fun guy to business with. This is important. - He stands behind his word. Some work had to be redone to better match the patterns. There were no questions, just a commitment to get it done right. I would have preferred it was done right the first time but appreciate his commitment to satisfaction. - Best price against the quotes I received. See the photos for reference. read more

Sal and his crew were great. Our terrazzo staircase seal blew and in the last rainstorm, we had a river running under our stairs and into the hallway. I called Sal on a Sunday, and he was over to inspect the job within hours. Once we agreed on the project/price, his crew started immediately and was done within 3 days, before the next storm could hit. The stairs look beautiful and don't leak anymore. He also patched up the stucco under the stairs without us even asking. We are very happy with the work and Sal is a good man who I feel good about working with. Thanks! read more

Sal and his crew are fantastic. Sal is responsive, honest and fair and his team did a phenomenal job on my front steps, which had been leaking. They finished the job in 2 days and even patched/reinforced an area under the stairs. He stands behind his work. And after the first big rain - the stairs are no longer leaking. They are beautiful again and look brand new. Thanks Sal!! read more

We had leaky terazzo on the steps leading to our house and Sal and his crew did an amazing job in fixing it and making our steps look as good as new. they worked quickly and unobtrusively and were highly professional. In addition, their quote was very reasonable. He was recommended to us by an amazing and highly respected home surveyor and we would wholeheartedly recommend them to anyone else. read more

sal and his crew were professional, on time, and gave us a great price. we had a set of stairs and mosaic that had been painted over with ugly paint. he ground down the paint, polished the terrazzo, and uncovered the mosaic underneath. after he polished and sealed, the terrazzo and mosaic looked absolutely fantastic read more

It is rare to come across a true craftsman, one who's spent his life honing his skill and creating affordable, elegant solutions so extraordinary that he proudly shares his decades of terrazzo repairs and creations when you first meet. Sal and his Rainbow Terrazo Co. is one of those rare finds. Having spent his early career learning from the old Italian craftsmen who transformed so many San Francisco facades with their artful use of concrete and aggregate stone, Sal has built and repaired a lifetime's worth of stairs. By the time we first met a couple weeks ago, large portions of our terrazzo stairs had collapsed into the basement. Much of the surface below was corroded, having been exposed to water and air for so many years. We were shocked by the very competitive price Rainbow Terrazzo provided - the cost for repairing the many cracks was well below the cost of replacing a single stair. But that was just the beginning. Did I mention that his bid included replacing many long-lost tiles on the landing, the voids long filled in with concrete? A complete refinishing and sealing of the entire entryway? Me: "Where do you find tiles to match?" Sal: "Ha ha ha. I already have them - I've had them for years." That's what 40 years' experience buys you. Of course, I would be remiss if I didn't mention how he cleaned, resurfaced, and built a concrete supporting wall beneath the existing staircase, ensuring a structurally sound entryway for the next seventy five years. His professionalism is unparalleled. He came when he said he would come; moved anything that was in his way; thoroughly cleaned up our basement when the job was complete, and put everything back. He and his team were beyond polite, indulging the intense curiosity of our 7 year old son on more than one occasion. Once you find a craftsman like Sol, you hate to let him go. Alas, there's only so much terrazzo repair a hundred year old Edwardian can muster. read more

While I think Steve C. below provided an excellent and comprehensive review, I feel compelled to add my own experience to the list of very satisfied customers. I rarely (if ever) write reviews but that's because I rarely encounter a contractor like Sal from Rainbow Terrazzo. Our saga is much like others and starts with the dismal, crumbling Terrazzo stairs on our 100 year old Victorian in Potrero Hill which after 10 years of averting our eyes and ignoring them, finally required a decision and while everyone else who saw them said they could not be fixed and would be a total tear down, Sal was unfazed. After explaining with complete confidence the detailed process for repairing and reinforcing the underside of the stairs, building new cinder block stringers caped with 4x12 timbers wrapped in rubber under each step, then explaining the very labor intensive process for cutting out all the cracks in the terrazzo, filling with matching color mix, grinding, sealing etc. we were sold. That said, you would have to have seen the sorry shape of our stairs to appreciate the magnitude of the job as literally every tread and riser were completely cracked with missing chunks of terrazzo and he also had to contend with a handyman special concrete patching job I put on 7 years ago. In the end, we avoided having to deal with the much more disruptive teardown/rebuild, and have our stairs looking practically like new. Aside from the actual repair and great results, Sal and his crew were incredibly professional, friendly, and polite. They showed up on time or early, worked like crazy, cleaned up and even washed the house down after they were done to clean up the dust from grinding. They are a family business and everyone on the crew is part of his family and his wife also works with the crew and specializes in mixing/matching the terrazzo. Sal is one of those rare old school guys who's all about honor and pride of workmanship. He pays attention to every detail and like other reviewers, I was impressed with his going above and beyond to locate and fix leaks in the siding and sealing areas that most others would consider not part of their job. By the time he's done with your job, Sal will feel like part of your family too :-) See pictures above for before and after both underneath and also the stairs themselves. read more

After years of watching my 135 year old stairs slowly break apart and finally give way, I had to do something. I had bids for multi thousands to replace them, but then Sal came by. "I can fix them like new" he said. "I have been doing this all my life. As a young man, I learned terrazzo from the Old Italians". His price was right on so I said we should do it. Well, he was marvelous, efficient and very polite, and often funny. He worked every day with his crew once the job commenced and he stayed, every day, until it was completed and really beautiful. This man and his Family, his wife too, worked damn hard and gave me much more than my moneys worth. He even came by to see I was completely happy and brought me a bottle of fine Spanish wine. The wine was very good too! read more

Not another simple review of how they are flawless, etc. Their structure appeared perfect,but I really felt the color of the repaired portions was a bit off. Sal dealt with me patiently and came back several times to work on darkening the shade. So, not just good price, but attention to customer service. Thumbs up. read more

This review is a bit on the late side, but...Sal and his crew ARE THE BEST! Super friendly, Super professional, and did a SUPER job on my front stairs! The terrazzo was cracked in a spot and the structure underneath needed addition support. Sal came out and inspected it and within 3 days the job was done and looking BRAND NEW! Highly recommended. read more

Wow. Great work. Friendly, and have to look with a magnifying glass to tell where the seams are of the patch/restoration he did. He matched the color perfectly (knowing ahead of time what it would look like after the sealer was applied!). Great job. Great work. read more

Sal is a honest business man and he and his crew did a fabulous job on the exterior stair case. Sal and his company is 10 stars. The job was 1) remove old seal 2) install new seal all around each terrazzo steps all the way to the front entrance door way 3) waterproof coating 4) repair chipped steps 4) replace water damaged wood pieces underneath the staircase located in the basement. Sal took 2.5 days to finish the job and the staircase and basement are spotless clean. Sal is amazing and I would use him again and again. I highly recommend Sal and his company. read more

So during a recent rainstorm, I took a look under the stairs and noted that there was a leak again and being a big upset, gave Sal a call and that perhaps something was missed when he originally repaired the stairs. He came by a few days later and he helpfully pointed out that it wasn't an issue of the stairs themselves, but rather, a small portion of the siding of the house next to the stairs that had cracked - thus allowing water to leak through. He then proceeded to patch up the hole in the siding AND seeing how distressed I originally was, put another coat of repellant on the stairs themselves. This was done without charge. What more can I say? They don't come any better. read more

Sal and his crew did fantastic job with our stairs. We recently had our stairs resealed and resurfaced. Also we had some dry rot repaired under the stairs. The results look amazing. Many of our neighbors have complimented us on how great our stairs look. It was a pleasure spending time with Sal over the course of a few days. Sal is quite a character and is very fun to talk to. He is very funny, lively, and gave me some great advice about home improvements and life :) read more

We had our terrazzo stairs sanded down and polished by Rainbow Terrazzo. We had four bids for the job and the owner Sal gave us the most competitive bid. He was professional in breaking down the entire process for us and what was entailed. The stairs look amazing and he truly brought them back to life. He even brought in a cleaning crew to take care of the clean up! Sal is professional and a pleasure to work with! read more

I don't write many reviews. And the ones here so far have done a great job of describing Sal and Margot's (his wife's) great work. I have contracted Sal for now 15 years for various jobs. He became known in my childhood neighborhood of the Richmond District because of his great terrazzo and general contracting work. Two things if you're a potential customer I'd say: 1) he's always taken each job personally--he spends time to speak to every customer in a way where he would not want to let down his best friend, and 2) he is very positive and creative--he looks for ideas to fix the problem, not ways why it can't be done. He offers a personal level of service that is above and beyond that you don't see often anymore, and he's done it consistently for 15 years I've hired him. On background, it is all about family for him. His two sons were taught by him when they were younger and in the 1990s all of them would come out to work on jobs. Today, his two sons, whom he is very proud of, work in their own contracting businesses. You wouldn't know if from his face or energy, but Sal has been doing terrazzo for 35 years, and construction for almost 50. He's a good guy. read more

I own an Edwardian 2-Flat Building with Terrazzo steps in Noe Valley with granite porch landing that had not been touched in over 112 yrs. It had cracks, chips, had missing tiles, & the marble entry walls on 3 sides of the porch were much darker in color than their original light grey! I had only one estimate to do the repairs & then called Sal, the owner of Rainbo Terrazzo Co. He came over promptly and gave me a very reasonably priced estimate for repairing, sanding, refinishing, & replacing missing tiles to their matching colorsI I awarded Sal my job. He and his crew were very professional, detail oriented & completed an outstanding job which I thought was Spectacular in every respect! He brought back the original luster & eye appeal that made my property look brand NEW! Sal also stands behind his work with a 100% Gurantee after the job has been finished! I highly recommend Rainbo Terrazzo Co., and Sal to you & would hire him again if needed!! I GIVE SAL A- AAAAA RATING !! read more

True Craftsman. Sal and his team repaired our leaky stairs. They filled all cracks and caulked all steps etc. They look awesome. They showed up early and worked all day. I would highly recommend Sal and his company. He came out promptly to look at scope of project and started the work the next day. I called others and they would come by on there own time. We will definitely use Sal when we want to update and polish our terrazzo stairs in the future. read more

Sal and team were great! They did our front steps and boy did they need help. Sal was easy to work with, and they were done in just 2 days. His pricing was negotiable and better than the competition. They cleaned up and didn't leave a mess. So glad we did this to our front stoop. It has so much more curb appeal! read more

Sal and his family are amazing -- top notch service, which is rare these days! He and his family painstakingly put our stairs/landing back together. Our stairs were half crumbled and they needed to re-build the stairs and re-do the terrazzo. We had a few different companies come out to bid for the job and not one would even dare to try and fix the stairs -- they only wanted to replace with marble or slate. We wanted to preserve the terrazzo....and I really think Sal is the only one doing this in the city. That's because it's hard! I watched the whole process and it was impressive. They were super courteous and lovely people to deal with. read more

Sal is the man. Do not waste any time or money (lots) going anywhere else - just stop, go to Sal at Rainbow. The man has been doing terrazzo since the dawn of time. He eats and breathes terrazzo. He will work with you, give you a deal (the best price in town), and the work will speak for itself. Perfect. If you go anywhere else for any kind of terrazzo work - you are a fool. Sal is king. read more

the reviews really helped a lot and it is exactly like all the other reviews, they are on time, efficient, clean and did a great job. Appreciate it very much and we are also getting them to repaire my mother's stairs. Keep up the good work ! read more

OMG. I have never had such a great experience with a contractor in my life. Sal and his team were absolutely professional in every sense. We needed a complete restructuring of the support under our front stairs which we had left for far too long. Sal came the same day we called and evaluated the situation. That evening we got his bid. The next day, we accepted, and by 3 pm he was there to begin cleaning out the work area. The next day, his crew was there to begin work. He has worked for four straight days and will finish in one more day. I am so thankful and overjoyed with the results so far. He completely replaced all the dry rot, patched, sanded, re-paved our landings and when it's all done, will completely refinish our stairs. I couldn't be happier. Well worth the price for speed, efficiency and finished product. Sal, you're a jewel. And such a nice, honest man, to boot. UPDATE: Sal and his team came back to patch the stucco on our house. Completely unasked for, but he said that it was the result of our failing stair structure and would improve the facade against rain etc. What a great guy. An artist and he really, really cares about his work. Thank you, Sal. We couldn't be more pleased with the finished product. Very respectful and cleaned up the work space each day. read more

Sal was one of the best sub-contractors I have ever hired. I have been a general contractor for thirty plus years as well as a commercial property developer and Sal has the characteristics that make for a successful tradesman.
