This is a very efficiently run company. We replaced 2 shower doors, and the job was extremely well done. Maria was very well organized. She knew about one of my favorite songs. "They call the wind Maria." Ahmed and Carlos did a find job. read more

I could not be more pleased with my new shower door. It is gorgeous. They are the ultimate professionals. Friendly and considerate. There was a configuration glitch with the handles and that was resolved beautifully. The cost of the door was competitive, especially since other companies did not include everything Alcosta included. I highly recommend Alcosta Shower Door read more

I'm a designer and have worked with multiple glass companies. Alcosta has become my go to. While the approach is somewhat different and scheduling can be a challenge (as far as identifying an exact day and time in advance), so far my experiences have all been very good with their team. The field technicians in particular are so kind and warm, and do a great job on installation. Lead time has so far been very good, even as busy as they are. They have never turned their nose up at smaller jobs, never tried to upsell me. Price is competitive, quality work, definitely recommend. read more

Huge satisfied customer ! From measuring to install today I wish I had more bathrooms . This job felt like family . 10 stars

"Man Forced to Pay Half Price for Shower Door." Yes, it's true. A neighbor on Nextdoor recommended this company and I decided to give them a try. The estimator came out promptly, and to my astonishment, the estimate was $1,000 less than a competitor. Don't you hate that when the estimate comes in half the expected price? I especially appreciate the fact the estimator explained to me some safety precautions. No one else had explained that to me. He explained the safety code regulations regarding inside handles, and the danger of injuring yourself. The installer came out very soon and I now have a beautiful shower door enclosure. Everything was A+, start to finish. I did not mind being forced to pay $1,000 less for my shower door. read more

Excellent!!! From estimate to install everyone was so help and efficient. The semi frameless looks modern and clean. We really appreciated their recommendation regarding the height read more

I've always said that to really understand the character of a business, it's not about whether there are any problems or not, it's how a company responds to a problem. Alcosta Shower Door installed a shower enclosure and 3 mirrors in my master bathroom 6 years ago. We woke up last weekend to one of the mirrors falling off the wall and crashing into pieces on the floor. For whatever reason, the mastic didn't hold. In talking with one of the owners of the company, he said that in over 40 years in the business, he'd never seen that happen, and I believe it. What made matters worse is that the warranty is only good for 1 year. That makes sense, because if anything is going to go wrong, it's probably going to happen in the first few months, so 1 year is typically fine. Alcosta could have "hid" behind the expired warranty, but that's not what happened. They decided they would stand behind their work and cover it under a warranty that doesn't exist anymore. That's what I call stepping up! Alcosta has done work in 2 of our bathrooms, and we're going to have them work on the 3rd in a couple of months. They have always done excellent work and have added the finishing touches to our projects. But most importantly, they stand behind their work! I can't recommend them enough!!! read more

I needed some parts for existing shower door. Called and spoke to Ted. He was really great - knowledgeable and the advice he gave me inspired confidence. Went to see them got everything I needed. Ted took the time to explain various options and show me his models which I really appreciated. When asked he offered his advice. A really great experience. I highly recommend these kind professional folks read more

I called and inquired about replacing our Steam Shower Glass Door. I had done a touch of research, and requested a quote for "panel/Door/panel" with an operable transom, clear glass and diamond seal. I forgot her name but she seemed to be head of the call center and receiving desk; she correctly advised me the options I was asking for were a bit pricey, and there were some alternatives an options with upsides that could bring the overall price down. I had asked for an operable transom and clear glass. The clear glass would have been almost unnoticeable without white tile, and the door can be left slightly ajar to accomplish the steam release that the transom had been intended for. She sent Phil to come measure, after I had agreed she knows more than me in the subject, and was willing to take advise on how I could reduce the cost of my glass. Phil came, he very carefully measured the finished opening for glass, and made a few recommendations based on his immense expertise. I could tell he was an expert because he had prompt responses that told me he knew what he was doing, and that I was in good hands. I always get nervous at these points in the project, and asked Phil flat out if I was doing the right thing in my selection, he said yes without a second thought, and I completely agree now that I see the finish product. We ended up doing panel/door/panel, with top and bottom hinges to minimize the visual component of hardware, and the cost! The price was about 1,000$ cheaper than the also recommended competition, so I would not hesitate in choosing Alcosta, just make sure you have a rough idea of what you want, and they will take care of you. It really is nice having "nice things" as practical as a shower door, that you get to enjoy every day. This was one of those purchases that makes me enjoy being an adult. Thanks Phil for the measure, the very knowledge desk staff, and the tremendously polite and talented installation crew. Together this company is an excellent choice for a high quality shower door installation. 5 stars. -Andrew read more

The whole experience from estimate to install went smoothly. The install ended up happening earlier than the initial quote which was a nice surprise. I highly recommend. read more

They arrived on time, took all their measurements with great professionalism which means no mistakes and when it comes to glass you can't make a mistake. Ive used them for years and when I have tried to call other glass contractors no one compares to Alcosta. read more

Every bit of the shower door process was super---from setting the initial appointment to measuring to install---Alcosta was recommended by my tile contractor. I was told my new shower door would be a 2-3 week wait but received a call in 9 days to set up final install appointment 2 days later and I couldn't be happier with the completed project. Alcosta Shower Door is the icing on the cake when doing a shower re-model! Prices are fair and work is meticulous. Thanks so much and now we've embarked on #2 shower for re-model! read more

Alcosta Shower Doors did a fantastic job installing my new shower doors. The installers were on time, very friendly and knew exactly what they were doing . They checked with me regarding the precise spot to place them. They were very price and explained how to clean them. Last but not least, they had the most competitively priced bid. My shower doors are beautiful and so pleased, I selected Alcosta Shower Doors. read more

Called around to other local glass shops which were all busy and seemed bothered you called them. Not with Alcosta glass. They answered the phone, gave me a fairly priced quote over the phone, and sent someone out who knew exactly what they were doing right away. Price stayed the same as the phone quote for a 7'X4' mirror and it was installed the next day in only 15 min. These guys are total pros so don't bother calling anyone else and you will save yourself the frustration and added expense of dealing with people who don't seem to care if you patronize them or not. read more

I highly recommend. This is a family business that takes pride in their work. As they should! Their prices were the most reasonable around and the quality was better than the door my contractor had installed for me when he remodeled my bathroom (and that one cost $400 more). The other company installed doors that had several areas with nothing guarding for leaks between panes or against wall. Alcosta Shower Doors are well sealed with a special strip of something that is hard to notice. I didn't notice it for a few days! My shower walls are not straight and one side was at a slant of about 1.75". I was sure I would have gaps - but I didn't! I couldn't be happier with these doors. I purchased one custom swing-door and one sliding door style. Both were installed perfectly. I added the diamond seal to my orders and have been very happy with it. Very nice people to work with. . read more

Phil came out measured sent me a quote and installed within 2 weeks. Great service and workers are considerate and professional. I would highly recommend Alcosta Shower Door. read more

In order to help other people in my position, go to Home Depot. A gentleman there was able to help me order the right size online, they dont normally have it in stock. For the business, my review stands. The behaviours I encountered on my 2nd visit are the worst I've experienced in recent memory. Thank you for the comment but the response you are looking for is just "I'm sorry for my behavior". Not I'm sorry that you thought I was rude. There is a difference. read more

If you're in the market for custom shower doors, the guys at Alcosta do a nice job, are friendly and it's a family business. They did the glass in both our bathrooms -- one an extra tall glass enclosure with a door and the other a European style shower "screen" on hinges. They came out and measured, then it took about a week to custom make the glass to our height preferences, then they returned for the install. They have a coating you can get for the inside of the glass that makes it resistant to water staining buildup so you don't have to go wiping down the glass after every shower. They give you a bottle of special cleaner to occasionally use on the inside of your glass only, and when used with a microfiber cloth it has been very effective. It has a lifetime guarantee. Yes custom doors are a little pricey....but they are nice thick glass, made exactly how we wanted them, and look fantastic. read more

We went in there to get vinyl for our shower door and they charged us $20 for 6 feet. Which is only &10 and they were laughing at me like I stupid!! Horrible Customer service! read more

We had a shower door installed by Alcosta Shower door (Hmm, that sentence sounds kind of redundant :) ) and the work, workmanship, and the treatment on the phone, in person (the wife and I visited the small showroom/office) was excellent! Bill talked us thru the options at length (thickness, clarity of glass, coatings, hardware, seals, mounting choices) and was very clear and upfront about things to get, and things that were pricey and not truly necessary (He was happy to sell them to us if we wanted though) I got a good feeling about the business right away. Ted came out to the house and did the measurements and he was very professional and pleasant as well. When it came time for the install Eric and James showed up right on time and had the door in in about an hour, and as before, both of them were very professional and pleasant and worked like lightning! They definitely knew what they were doing! After the installation, care and feeding of the glass was completely explained (even though Bill explained it all to us when we visited the office) and they left a bottle of the special cleaner and instructions. Who knew that a squeegee was bad for shower glass? I didn't before they explained it too me :) They cleaned everything up and the only thing they left to mark their passing was a beautiful shower door! :) I would definitely recommend Alcosta Shower Door to anyone who needs their services. I love using local businesses and even more I LOVE finding contractors that give me peace of mind and do stellar work! Their prices were fully in line with other bids I received for the same products and they even gave me $100 off for paying in cash (I like doing that, and it made the deal even sweeter!) and appreciate businesses who do as well :) I use Many contractors for a great variety of work since we own rental property, and I love the fact that I can add these guys to my list of "no headache, do the job right the first time, and quickly" contractors! Need shower glass, use these guys! read more

I have used Alcosta Shower Door for all 4 of my homes. Several of the bathrooms had to have custom enclosures and they helped me find the right one for each of the bathrooms. Beautiful shower doors really added value to the home. Recently the shower door in my master bathroom would not close. Ted came out the very next day and determined problem. He fixed it and the shower door is like new. Alcosta Shower Door stands behind their work and product. I would highly recommend Ted and Alcosta Shower Door!! read more

I submitted a request, they contacted me, we set up an appointment and a should be enjoying a new shower enclosure within 2 weeks

Friendly staff, super quick service, could not be happier with our custom made shower door. Very happy I decided to go with Alcosta as opposed to the other shower door companies. Most reasonable price, and the product looks incredible. read more

They have the worst person to talk to on the phone...dont know who gets such idiots to sit on the phone.....please hire good ppl.....

Small business.....I beleive in taking care of the hard working people. Came and measured on Friday....told me 3-5 days. They will call 2 days before. 7 days goes by. I have to call....they tell me the installer had a baby....Great news for him....so when are you going to call me and say you can't install it? I asked for a few dollars off and she said no....spent 10 minutes justifying what happened....do you only have one installer? Can't call a client? Sorry to say I will never use them again. If I don't show for work I have to call.... read more

I was surprised by the recent negative reviews, but Alcosta Shower Door was one of the few glass companies to actually call me back when I asked for a quote. Since we had a construction crew at the house everyday, I had them let Phil, the estimator, into the home without me. After taking measurements Phil called me to discuss his ideas for the enclosures. He even left a sketch of his plans on-site because I couldn't meet with him at the time. I appreciate that he didn't try to up-sell me on the colorless glass and he explained clearly when and why we'd need a headrail for one of the doors. His quote was a third less than other companies I'd gotten quotes from. I couldn't be there for the installation, but the construction crew didn't report there being any problems. We've been using the doors for about 6 weeks now and they remain sturdy, clean, and functional. read more

Nothing bad to say here about Alcosta Shower door. My only issue at first was getting them to respond. Took them about a week. Once I got them out everything went perfect. They showed up when they said they would. They had a fair quote (and actually came in quite a bit cheaper than a few other places). I liked the master shower so much that I had them come back out the handle the other bathroom shower. Everything turned out great. Can't ask for anything more. Thanks Alcosta. I am much cleaner now! :) read more

I manage a small apartment complex in Danville and have used Alcosta Shower Door for 15+ years and with over two dozen shower door installs we have never had a shower door leak which has saved us a lot of money in repairs to the sheet rock. The original general contractor that recommended them to me said he had never had a door leak either and they are the only ones he will recommend. Several other contractors I have worked with over the years have also highly recommended them. They show up on time, finish the job quickly and never leave a mess behind. Their customer service has always been very good. read more

Beautiful shower door! From day one it was a great experience. The sales rep showed up on time, bid was consistent with other bids. Ordered on a Friday and they called to schedule installation the following Wednesday. Installers are professional and friendly. The quality of the product is exceptional. Perfect final touch to my beautiful shower! read more

I have used Alcosta Shower Door many times - they are the best! At a previous address in Dublin Ranch they installed a couple of shower doors we loved! They looked beautiful and the pricing was very competitive. My friends parents loved the doors so much they then hired them to do their home in Glen Eagle in Pleasanton. We are moving into a new home soon and I can't wait to have them install new shower doors. Eric does a beautiful job installing and his family staff at the office is the absolute best. Thanks guys! read more

We have done a total house renovation and are our own general contractor, so we have come into contact with a lot of subcontractors and vendors these past few months. One day I was nearby Alcosta Shower Door and knew that getting a shower door for the master and guest baths was on the to-do list, so I figured I would just pop in to start the process to see what was involved. Next thing I know, Bill is following me back to my house to take measurements! 5 days later the door was installed for the guest bath! They made it SO incredibly easy for me. They clearly explained my options and voila! I had a shower door. Fast forward two weeks later when I am now ready for the master bath shower door. I go into the shop to see the various options, Mariah says that Phil will come out to measure the next day. Mariah is very knowledgeable and helpful to sort through the choices. Sure enough, Phil calls me that next morning to give me a time of arrival. Phil takes measurements, explains my options, and in 2 weeks I'll have that door too. There are always complications during a remodel, so when something goes smoothly, it's such a pleasant surprise. Alcosta Shower Door wins the prize for easiest vendor to work with! Highly recommend!! read more

I have used Alcosta Shower Door for over 20 years in several homes we have owned. It's nice to know I can always count on them. The service is fantastic. I attribute the service to being a family owned and operated. There expertise in helping me choose the right product for the project, is most helpful. I feel it's never a hard sell, just helping me arrive at the right choice. Thank you all for a G R E A T job! My shower enclosure looks beautiful!! I wish I could post a picture of it. Thanks again and until the next project... I'll keep recommending you to all friends . Susan C read more

We had both frameless and framed shower doors installed late last summer. This family owned company was both reasonable and efficient. We needed to call them back once as one sliding door opened slightly on its own. They came out quickly after we called and fixed it. Only problem I had with them was communication between the people who work there seems to break down sometimes. I would use them again. read more

I am extremely pleased with the great service I received from Alcosta Shower Door and I LOVE my new shower door! The people that I dealt with at Alcosta Shower door, from the lady in the office to the gentleman that came and installed my door were great! I almost felt like I was dealing with people I had known forever! I felt very comfortable and safe having them in my house (and these days you need to feel confident in that) They have been in business for years and I think that is a true testament to the quality service that they provide! They were also very accomodating to my schedule since I had animals that I had to schedule around! I would recommend them highly and in fact, I already have! They wil be at the top of my list to call on again when I am in the market for another bathroom remodel!! Thanks Alcosta Shower Doors!! read more

We needed just a handle for an old shower door, and they stopped what they were doing, without the least hint of annoyance at being interrupted, and went in search of the part. Then, they looked for and found a rubber insert which we hadn't asked for but would have been up a creek without. When I asked what we owed them, they told us it was FREE. Service just doesn't get any better than that! read more
