Amazing work on our old style pool. Never looked so good and they gave a warranty. full crew had it done very fast. read more

Zero and negative stars. Jan left a very unsafe work site. He took zero responsibility for causing me to trip on a sting line they left up for months while weather delayed the work. This negligence caused me to trip over a string line that was left up for no reason for months. This negligence caused me to trip and FRACTURE MY ARM, DAMAGE MY KNEE, and I have zero feeling in my thumb now. Ive lost work, sleep, certifications that I rely on for my livelihood. ​MAJOR MAJOR ISSUES. Jan ​ took zero responsibility for this negligence. He wanted to quiet me down by offering me 2k after he charged me 30k for concrete work that he never did. I could go on and on..and I have not written this review till now on purpose as its been a real struggle to deal with the damage done to my body, mind and spirit. Jan....when u read this. I hope your slimy business practices keep you awake at night. You owe me 30k!! About 15k for physical therapy. 25k for the work I lost due to your negligence. And ur bullsh!t offer to pay me 2k to shut me up...I denied that as my word of mouth is worth more than that. You are not to be trusted. DO NOT HIRE THIS COMPANY.. they have no standards and will serve u a big plate of BS and call it a snack. Zero stars! read more

Update to my previous review it won't let me remove or edit: Jan's wife called me after seeing my review and they finally came out to see what my complaints were. Travertine that had big holes were replaced. The cement deck apparently cracked so much because the cement company had inadequate mix. Jan replaced the cement deck using a different supplier and so far no cracks. He replaced the entire pool surface with new fiberglass from a machine this time. So he made good on our complaints. The only complaint I still have is the time it took to complete. From May 21 2025 to August 4th they were here only 13 days total. I realize they were squeezing us in their schedule, but took them 2 months the first time too. If you're very patient and have good cement suppliers Jan will get the job done. read more

We had our cement pool's surface re-fiberglassed by Shamrock. About a year later, we noticed a powdery substance accumulating on the bottom, which we suspected might be the gelcoat disintegrating. Jan and his team returned to the pool under the full warranty. They sanded down the entire pool and applied a new coating using a different, new process. read more

I want to thank Jan and his crew for an outstanding job on the repair of my fiberglass pool. Jan was very thorough in explaining what needed to be done to repair the crack in the bottom of the pool. Jan and his crew were on the jobsite as promised and on time each day for the repairs. I could not be happier about how well the job went and how the completed repairs looked, and the professionalism of Jan and his crew members. I will be recommending them in the future. read more

DO NOT HIRE THIS COMPANY! We had our 35 year old fiberglass pool resurfaced 2023. New coping, cement deck redone. VERY expensive, but Jan assured us it would all turn out fabulous. We paid top dollar, we assume they used very sub par materials for the look of everything now. Travertine coping has large holes that were filled with something that is now coming out. We paid for stamped concrete and agreed to just brushed, there are MANY big cracks, not hairline and the color faded, the cement is chalky. It hasn't even been two years yet. Jan suggested an overlay, at first he said at no more cost to us now he wants to charge another $6000! They also blew out the solar heating lines when doing a pressure test, he did end up paying for that after many requests. The main drain has zero suction the pool light doesn't work at all since they replaced it and they cut the cord so short it can't come to the surface. The pool itself looked great at first, but now that we are swimming the feel is not that of smooth fiberglass, it feels like a cement type surface. The non slip for the steps and seat are extremely rough on skin and suits, it feels very course as apparently they used sand which continues to flake off. There are marks and scratches and discoloration on the bottom and sides of the pool. Each time I take in my water to be tested it comes out perfectly balanced so the water isn't the problem. Jan just said to buy a stain fighting product instead of figure out what is going on with it. No answers as to why it feels so rough. Now it has tiny bubbles in the surface. Sent him a text Oct. 2024 asking about what kind of coating was used and nothing, no responses at all. Very disappointed for the amount $$$$$ of money spent. Not even two years later he's defending and embellishing everything after seeing this review, instead of just saying sorry we aren't satisfied and how can we help. I have saved every text and picture throughout this disappointing project. read more

I realy dont think this place can get any better to be honest but my parents had their pool redone it was quite some time ago but i must say the concrete work that was done around the Pool was great but the Tile work in the Pool was absolute garbadge not long after the Tile was put on they started slowley but surely falling off so my Dad who has since passed away called them and told them the Tiles are falling off so they came out and said we dont make that style anymore so instead of trying to match the Tiles they threw on Tiles that wher smaller and didnt match at all and to this day they are still falling off if i worked for Shamrock pools i would be absolutley embarrassed that this is the finished product absolute Garbadge our Backyard is Beautiful but the Pool makes it look Like crap with mismatched Tiles and tiles that have fallen off this Company should be called SCAM ROCK Pools read more

I guess there is a reason I withheld 5 stars from my previous review. The fiberglass began cracking where the new swim shelf met with the old pool and I began losing water. I called Jan as the pool was still under warranty and he had his crew out quickly. To patch the crack, water had to be drained and refilled (at my cost of course). They patched the crack and repainted. The paint did not match exactly but close enough (new paint vs. paint exposed to salt water and sun perhaps?) A few months later, the crack began to show again, in the same spot. I contacted Jan who said he would schedule a time to fix it but that never happened. I have since sold the house (disclosed crack to new owner). Unfortunately, I don't think the warranty has to be honored after I sold the house. I'm not a pool builder, or concrete worker, but I watched them build out the swim deck shelf. It was framed with old wood and then filled up with debris from the old tile/pool surround before being filled with concrete. When the wooden forms were removed, I remember them grabbing concrete and using their hands to cover up the debris that was still visible on the side of the shelf were the wood forms had been. And while they did rebar the top (only the top few feet at best), I don't remember them attaching them to the old pool surface in anyway to prevent movement. But again, I'm not a pool builder and their way may be standard. All I do know is that it's shifting, causing cracking, which they repaired once. It shifted and cracked again and I was ghosted presumably because he knew I was selling. It's a bummer too, being as I really liked him and his family during the job. read more

For Shamrock Pool Fiberglass, professionalism is a given for Jan and his crew. I want to talk about an aspect of the project, perhaps not as glamorous but just as vital. Permit and Inspection. Jan had my permit application submitted and approved in Feb. Work started in May. He planned ahead. Inspection is stressful for the homeowners. The inspector gave a time frame for his appointment. Jan was always here before the designated time. We waited patiently together. He talked to the inspector. Quite reassuring. Finally, I usually have the restroom available to the crew working on my property. Jan, was the only contractor to bring on-site porta-john. Very beneficial for everyone. Meet him and talk with him. You will be pleased like me. read more

I noticed that our pool was leaking water and contacted Shamrock. The fiberglass was covered under a three year warranty. Within a couple of days they had determined the cause of the leak and also made the repair. It was all very simple and cost nothing since it was under warrantee. We couldn't ask for better service. read more

We had a positive experience overall. The workers were prompt and professional. ( I made sure to tip them because they worked hard in blazing heat) I thought Jan's price was fair and the work was great. They were a tad slow in doing warranty work. But Jan did keep his words and did the warranty work at free of charge. Overall, I would definitely hire them again. read more

Jan came to my rental and assessed my issues. I had limited options due to having a fiberglass inground pool. He offered multiple options for repairs. Work was done within a week and my tenants were satisfied with employees and service. Would definetely recommend! read more

We had a old pool that was fiber glassed 30 years ago, need to be redone. Was given Shamrock to consider by a pool technician. Estimate was done immediately, they also have financing available (which I didn't use) and the work was started as soon as I asked to be put on the schedule. The crew were quick and did a great job, the attention to detail was great and left no clean-up for us, very satisfied read more

Absolutely number one for any major construction job in our eyes. Long story short, go with Shamrock and you'll be happy you did so. Get it done right the first time with a smile. We had contracted another company to renovate our fiberglass coated pool a couple months ago. There are very few contractors here in the SF Bay Area that will even touch fiberglass, and we went with one we'd had good experiences with in the past. They started in mid April and from the start it was a disaster. After weeks of delays, lack of communication, and shoddy work, the contractor simply stopped all work and communication completely in late May. We tried calling, emailing, texting, and nothing. There was some dodgy things going on with the company and they are no longer in business. We stared at a completely empty pool with holes all over the place, tiling unfinished, walls lightly sanded but still disgusting, and a main drain that was completely clogged by the prior contractors shoddy work, wonderign what in the world we were going to do. I sent an email to one of the other two companies we could find that did fiberglass. After hearing our plight, they completely cut off communication with us - unwilling to pick up the pieces for us. Totally frustrated and beyond belief, we contacted Shamrock Pools on a Thursday night and Jan was out Monday morning. He gave us a fair bid and got the work (re)started in just another few days. This company moved some things around to get us in fast and saved us in our time of need. Our pool is now more beautiful than it has ever been and we are beyond thrilled. The work was done fast, efficiency, and expertly. Shamrock could have taken advantage of us and quoted us an outrageous bid, knowing we really had no other option at that point, but they were responsible, respectable, honest, and more than fair. I heartily recommend Shamrock pools for any major repairs, construction, or renovation read more

Jan and his company are extremely responsive and knowledgeable and accommodating. He took the time to come and look at my pool situation on a Saturday, made recommendations that didn't even include work that his company would do and then invited me over to pick up some excess tile grout that he had. He just gave it to me with instructions on how to use it, but without charge. He's truly a man of integrity. To top it off, his wife sent me away with some of the freshest and best salsa that I've ever had. I recommend this company if you want an honest and knowledgeable team that will provide you with the exact solution needed for your pool. read more

I would highly recommend shamrock pool fiberglass. Jan, the owner, was very responsive and very knowledgeable on resurfacing pools. My husband and I had been putting off contacting anyone since we didn't know much about pools. Jan came by and walked us through our options even giving us great ideas to upgrade the function of our pool. After checking out other companies Jan was the most responsive and was able to start the work quickly. Jan's team was great, always on time and kept the yard clean throughout the process. They worked quickly start to finish was a 3-4 weeks and most of that time was waiting on materials that Shamrock Pool Fiberglass has very little control over. Overall, I am very happy with the results and encourage you to make the call! read more

Had a major leak in our fiberglass pool structure. The repair was done very professionally and timely. Each step was throughly explained and supervised by the owner. They also found other small leaks and repaired those also! It was a pleasure working with Jan and his crew! read more

These people are terrible! They promised to fix my elderly mothers pool as she needs it for physical therapy. They committed to doing the job. Then they called and said were not doing it because they found a BIGGER JOB!! Who does that?!? I never dump one of my clients I've committed to for a big job. That's horrible!! In addition when I called back they then tried to come up with some BS about being sued if my mom falls in her pool!! So basically she has no faith that they can do the job proper?! Also your company has insurance so if by a long stretch that did happen the insurance takes care of it! In summation don't hire them unless your spending $20k to keep their interest! As all my followers know 90% of my reviews are positive so for me to come in here with a 1 STAR SAYS A LOT! Shamrock you should be ashamed of yourself! read more

Horrible business to work with. I would give zero stars if possible. We had a leak in our pool that they failed to diagnosis correctly... thousands of dollars later our pool is still leaking. Their response is they fixed what they said they would. Of course because they knowingly fixed what did not need to be fixed and charged an arm and a leg. DO NOT USE THIS COMPANY! Trust all the bad reviews they have because they are accurate. **Update: I misunderstood that Shamrock misdiagnosed the leak, but they did not. My mistake, and I will recognize that here. Regardless, the owner Jan responded to this review by calling me a "bold faced liar" rather than try to explain the misunderstanding politely. A sign of unprofessionalism and immaturity that is absolutely not a lie because it is writing to me. read more

If you're looking to resurface or refinish your pool, you've come to the right place! I have not had any pool work done in 20+ years, so it took a bit of investigating to find the right place. When I called Shamrock Pool Fiberglass, the owner Jan Moreno set up an appointment. He went into great detail regarding what it would take to make my pool look new again and better than before. My wife wanted the pool to look blue. He explained the fiberglass and the gel will be a bright white, but the color of the sky will make the pool look baby blue. We worked out a deal and I signed the contract. This was back in December 2020. He said all his people follow COVID-19 rules such as wearing masks and using a bathroom at another location (not at my house). The men were very nice about everything. If I had a question about something, they explained it, and we all kept our distance. The work that was being performed was something special to see. All of the work was done to my liking and very professional just as Jan Moreno said it would be. Jan even came on the last two days to spray the fiberglass in the pool. The pool resurfacing came out great and now the water looks baby blue! Our friends that come over just love the look of the pool and at night with the pool light on it's great. Many thanks again to Jan Moreno and his company Shamrock Pool Fiberglass. read more

Jan and his crew did an amazing job on my pool. We got our tiles removed and beautiful new tiles put on. They re did the entire surface of inside the pool and used this beautiful light blue color.

We bought our home and the pool needed a lot of work. After calling several places and having them all come look and get quotes. Pricing varied from each one with the cheap route to just coat what was there to a complete re-glass and gel coat. We had algae constantly coming back even after professional maintenance . We went the full package new tile and jets as well as skimmer tile and filter housing. Jan had his guys come in and strip all the tile and completely sand down the existing coating to get down to the original fiberglass after the re-glass and gel coat we have not seen anything but clear water. They do spectacular work and fast as well. If you have a fiberglass pool, going anywhere else would be a very bad mistak. read more

Jan and his crew did a fantastic job on my new Fiberglass pool. The communication, professionalism, expertise, reliability and suggestions went above and beyond!! I could not believe how quick and efficient the project flowed and would recommend Jan and his team for any pool and backyard project. Big thumbs up!! read more

The owner and workers were very nice and knowledgeable. The job took a little longer than expected but with COVID and my particular materials having to come in from Florida (which was the supply store not their fault) it was understandable. I am very happy with the final fiberglass product. It looks like they caked it on very thick. I had a couple long cracks with leakage and they put steel bars to reinforce the area. There is not a trace of any former problems. They even coated all the way into my skimmer and put tile leading in as well. Nice touch! No one did that before. I am a 26 year pool owner. Love my dolphins! read more

This is the most unprofessional business you could ever use we hired them to resuface our pool what a big mistake they did such a terrible job they rolled the fiber glass we contracted for it to be sprayed it looks like an asphalt patch job our wall between our pool and spa slopes it uneven they let the fiberglass drip down on all of our stairs and benches too where it puddle at the bottom of the stairs and benches they threaten to walk off the job when we complained and told them we would not give them anymore money they had no one here to over see the job they got 16,800 from my 86 year old mom on the second day tge owner would never come in and sit down with my mother to go over anything with her he took advance of her knowing she was disabled and could not go up and look at the bad job they did they never cleaned anything up our deck was left with fiberglass all over it the owner has a really bad mouth doesn't want to hear anything you have to say the people that work for them only one if them spoke emglish none if them had drivers license the daughter sat in the truck all day didn't check on anything they where doing when we complained the owner wouldn't come and look at what we where upset about they plugged 3 of our het holes in our spa we our now hiring an attorney so we can get our pool fixed the right way I would NEVER HIRER THIS COMPANY JAN MORENO the owner is so unprofessional he should not be in business he doesn't know how to treat people he just took advantage if my 86 old Mother who trusted him to do the right thing and he left her with a bigger mess read more

I was very very happy with the final result. Just used my jacuzzi for the first time in 7 yrs! Jan's team was clean and efficient. He followed through on his promises and at a very reasonable price due to the off season. I had a 30 yr dated and ugly pool and now I love the coping and fiberglass. My pool sparkles and has added value to my house. I wish I had done this years ago! Cindy in Danville read more

These people sure put the SHAM in Shamrock! We hired Shamrock Pool to fix a large crack in our swimming pool and it turned out to be an absolute disaster! The owner assured me that his company could fix the crack and stop the heavy leaking of our pool, however after one week of work and $17,000 later, a large bulge soon opened up right in the same place where the original crack was. Jan, the owner, came over to look at this new problem and said that it was due to rainwater seeping in. I have lived in this house for almost 40 years and seen many rainy winters with no pool problems, but he promised to only charge us for materials used. We agreed, as we just wanted the pool fixed. Jan ended up charging us another $5,000 for this latest work, which was just to shore up a small area behind our skimmer! My family and I didn't feel that it was worth fighting over, especially if it really was fixed this time. Not even four months went by, when the same large crack opened up again in our pool. That was when I finally got it through my head that the $22,000 work Shamrock had done was for nothing. We found a wonderful fiberglass repair company in Martinez who finally fixed our pool for $6,700, a fraction of what Shamrock charged us. This new company said that the only way to truly fix our cracked pool was to use multiple rebars, one for every foot of crack, otherwise it was like trying to close a gaping head wound with a bandaid! Our pool has been crack free for over one year now, no thanks to Shamrock. Please, let our $22,000 mistake serve as enough of a warning to stay away from Shamrock Pool Fiberglass and find a different company who actually knows what they are doing and doesn't just care about the money. read more

We have an indoor pool that had to be redone in fiberglass. It's an interesting kind of situation that required a special touch. I met with Jan. We went over all the parts of the project. He came out and did my pool with his crew quickly and efficiently. There was a little miscommunication about the amount of cleanup that would be required for an indoor pool. But that was resolved quickly and fairly and I am very happy with the work they did and I recommend them. read more

We have to have our pool redone after 25 years. The staff was very friendly and did their work efficiently. We are very happy with the results. read more

All I did was call to see if the company serviced my area. The lady who answered sounded irritated right off the bat. She continued to tell me that they don't do any new installs only pool remodels. She gave me a high price as the start point at 70k and said it only goes up from there. Then she gave me the name of another company to call. She was pretty rude and didn't seem to want any new business at all. read more

Don't use this company. We paid 18K for a leaking pool that they have decided, despite their guarantee, not to fix. There complaint was too much ground water but in 21 years of owning this property (and multiple fiberglass work done over the years) have we ever had so much ground water that the fiberglass literally split the way it did with this company. I now know that Advanced Pool coatings is the company to use. So much for shredding 18K for nothing. It is now mid August and there is absolutely no ground water and the pool fiberglass continues to crack. read more

When Jan heard my family was coming for my moms funeral and my pool was unusable he moved his schedule around to get my pool ready. In my book that says a lot about a company. Although Shamrock wasn't the lowest bid, I could tell they knew how to get the job done. I was very impressed with the office manager and how she always got back to me with any questions I had. They gave me a very fair price. I highly recommend them! read more

The crews were knowledgeble and friendly. Always on time and curteous. The project was completed on schedule in about a month.

They did a great job for me on the date that I asked for. read more

Shamrock Pool re-fiberglass lined my pool almost 11 years ago. Recently, I started getting some rough spots and fibers coming through on my pool steps. I called and asked Jan what I could use to reseal the problem areas. He told me not to do it myself, that he would have his guys come out and do it. Remember, it's been11 years. His guys came out, sanded and resurfaced, and I'm a happy customer. It's nice to see that Jan stands behind his work! read more

Shamrock Pool company was the best!! Professional & did a great job. I highly recommend. Our pool looks beautiful guys! Thank you

Jan Moreno with Shamrock Pools is great. He did my pool a couple years ago and I highly recommend them! Customer service is so important these days and they are all about making sure you are happy with their work. So refreshing to find a company that stands behind there work! Thanks again!

I called this business for a quote on my backyard. The date a time was set up so I took time off work to meet with the representative, who happened to be the owner, at my house. After about two weeks passed I called and inquired about the quote. I was told they would have me a quote within a couple days. To date I have not received a quote, a phone call or an email. This wasted my time and money since I took time off from work to meet with him. This business is completely unprofessional. I would use extreme caution if your thinking about hiring this company. read more

Shamrock has fiber glassed our 60-year old pool several times, replaced equipment and fixed several leaks over the 40 plus years we have been in our home.

We recommend them highly and without reservations. read more
