A window broke at my father's house on a Saturday. I left a message for Celtic Glass knowing they would be closed. Maryanne called me first thing the following Monday morning with some suggestions while they replaced the glass. The entire staff was professional, friendly and especially happy to help. It was great doing business with an established family business who understood my situation and responded quickly. Nice to see there are still businesses around like this. Thank you Celtic Glass! read more

I reached out to Celtic Glass with a custom project I needed. I received prompt responses and a few clarifying questions to better understand my project needs. I requested a custom top for a small approximately 3 gallon betta fish aquarium I have. I am very happy with the result and paid a fair price. My item was ready quickly and I now have a go to business for my glass needs. Thank you! read more

See all

Very responsive and good prices. Happy with their work replacing a large broken window, too.

I had two opportunities to experience the service at Celtic glass and can honestly say they have a large assortment of different types of glass, they are knowledgeable about the products they sell, are patient enough to explain each and have reliable installation services, and great turn around time. Thanks Celtic Glass for the great service, I'll be coming by for all my glass needs. read more

Great Company and very professional!!! I highly recommend them. I received a fast response to my broken window mishap. The repairman came to my location, took all the measurements and glass was ordered the same day. Installation was done within the same week. read more

Celtic Glass - New Glass Installed - Windows Installation Near Me - San Francisco, California

I've used them a few times to replace screens and install glass on my deck railing. Always great service and high quality work.

Celtic Glass replaced the double glazing units in 4 wood frame double hung windows in my 1928 house. Christian and his team were easy to work with and efficient. He came out to my house to take measurements, and a week later the windows were replaced. Christian was knowledgeable and pointed out and repaired part of a frame that had some dry rot. Most importantly, they look great. read more

I recently ordered a custom glass topper for my dresser. I sent my measurements via email to Maryanne and my new piece of glass was ready for pick-up a few weeks later. I was very pleased with the service and the glass was a perfect fit. I would not hesitate to order from Celtic Glass again in the future. read more

Extremely easy to work with, friendly, very good prices and overall very pleasant experience!

We needed a window screen repaired, they did a great job. It was easy to install and close to our home.

Hired Celtic Glass to fix broken window pane. Fair pricing, excellent service, and reliable. Would hire again.

Great place brought in measurements for two pieces of glass in the am and got them back later that afternoon. Unfortunately for me I measured them wrong. Too big. Called Celtic they told me to bring them back they would fix them. Got them back the next day at n/c. Great Customer Service read more

Best glass company in SF. best pricing by far and quality work. I'm a general contractor in sf and I always use these guys.

I like to support local shops but Celtic Glass is tough to recommend. While they are friendly and professional in the shop their follow-up is poor. Twice I ordered glass from them. Twice the order was 2 days late. And my orders were simple and straight-forward. How would they handle a difficult order? They don't seem to care about the small purchases since they most likely survive on large, commercial orders. I would not go there if I really need something fast. In addition I tried to call them about 7 or 8 times during regular working hours and not once did they answer the phone. read more

Great service! Called Shaun at Celtic in the morning about a broken window and he came out and fixed it the same day. Friendly, helpful......no problem! read more

Great local Family owned, and operated company. Very friendly, and accommodating. Pricing is very reasonable too. Maddie knows her glass well, and is very attentive, plus sets proper expectations on scheduling for delivery. I have done business here more than once, but this is my first review, and realized it has been a pleasant experience every time. read more

Best place around. I had them come out they gave me a fair estimate and the final pricing was the same as the estimate. Service was great and the work they did was even better. I have even recommended to friends and family. read more

I have been getting glass from these guys for a few years since I have lived here. They either cut it on the spot or order it to pick up on the next day. Very nice guys and they let you know exactly what you need read more

Called them for a broken window in early December. Set appointment for the 8:30 the next day. Called them at 9:30 because no one showed up. Got "oh we forgot". Guy shows up 30 minutes later, says he will order the replacement and have it in later in the week. Didn't hear anything from them. Called back and got told "we're really busy" then "I suppose you want this done by Christmas". Responded "No, I wanted it done last week when you promised to have it in". Then got told they were really busy and would get it installed at the end of the week. So two weeks in I had enough. BTW, never heard back on my window they "ordered". Contacted Cole Hardware and used their referral service. Bottom line, don't waste your time with Celtic. read more

THE WORST SERVICE EVER!!!!! DO NOT GO HERE!. First of all i dropped off a small piece of glass from a coffee table to get replaced at 2 p.m. and was told to come back at 4:30 p.m. to pick it up. I get back at 4:30 p.m. to pick up my replacement glass and the store was wide open with no one inside to assist me. THERE WAS NO ONE IN THE STORE FOR A WHOLE HOUR! I waited outside for a whole hour and when the people that work there FINALLY get back they refused to talk to me because they said that they close at 5 p.m. were closed for the day already. I had to yell at the guy and tell him that i been waiting for an hour outside and was told to come back at 4:30 and i wont leave until i get the piece of glass back that i gave them. The guy finally goes to the back of the shop and told me that they didn't make the replacement glass that i ordered and the piece of glass that i dropped off to them was still in the back. I told him that they have horrible service and that they promised me my replacement glass and i get nothing after all that waiting. He didn't even apologize to me for the inconvenience. He said "oh we can do it for you tomorrow morning" i just asked for my original piece of glass back and left there store MAD. Once again DO NOT waist your time at CELTIC GLASS CO. because they do not care about customers and small jobs like mine was, they only care about bigger jobs that are gonna make them big money and don't care about regular/small jobs. Celtic Glass....YOU GUYS ARE THE WORST! read more
