Contacted Anthony of Glendora Windows to get a quote to repair two vertical sliding windows that were no longer staying open anymore. He was able to quickly get Garrett (technician) to set up an appointment with me to take a look at my windows and provide a quote. Fortunately they had the parts in stock and were able to repair both windows quickly. I think it was only 3 hours from the moment I first called to the windows being fixed! They did great work and everything went straightforward. I highly recommend their services. Besides the window repair, they work on glass/mirror, new windows, window screens, wardrobe doors, and shower doors. read more

Asked the right questions for our job. They are local and have good ratings. We are just in conversation at this point

I moved into an older house with a slider door that was extremely difficult to open/close and a window screen that was horribly patched up and also didn't work. I received an estimate that at first I thought was pretty high but I agreed. He took the screen door and also a window screen back to his shop for repair. They sent two gentlemen out to install the screens and to repair the slider door. They were both so meticulous in removing the slider door and installing new wheels, cleaning out the rails and reinstalling and making sure everything lined up. They were just as meticulous when reinstalling the screen slider and making sure both slider and screen locked. I can now open and close both slider and screen with one hand. I love and appreciate the work they did. It was worth what I paid. Thank you all very much. They also were nice enough to provide me with preventive maintenance so the repairs would last a long time. Thank you Glendora Window for your AWESOME service! read more

We had the stationary part of a dual pane, low-e window get broken. Friendly installer. Super fast estimate, measurements, delivery and installation. Measured twice to assure perfect fit. Fair price, quality product, expert installation, insurance approved. Hope we are done with broken glass, but if not, we will call Glendora Window again. Our only hassle is the new glass is so clean! We will have to get the rest of the windows cleaned once the weather improves. read more

The screen on our patio door needed to be replaced and we were so fortunate to have found Glendora Window. The entire experience was unbelievably smooth, mostly due to how Anthony and Garrett listened and responded to our needs. They communicated every step and process with us, including a follow up visit in order to replace the interior handle (per our request). Both Anthony and Garrett were amazingly helpful, courteous and friendly. They found a solution to fully satisfy our request. The company, as a whole, truly cares about their customers and the services they provide. The quality of their services and products are exceptional. We wouldn't hesitate to recommend Glendora Window to anyone. Just give Anthony a call and see for yourself. You won't be disappointed. Thank you, Glendora Window!!! read more

Glendora Window - We won't be removing the fixing tape until a week later, but I can't resist giving it a good review. - Windows Installation Near Me - La Verne, California

Anthony and his crew Garrett and David did a fantastic job installing windows in my house. I had 9 windows replaced and two new screen doors installed. Anthony had a great price and the so far the Windows are great. Anthony was quick to communicate on delivery and install dates. It took less than a month to get the windows. His crew Garrett and David were very professional during both the install of the windows and doors. (They were done on different days because I ordered the doors after the windows were completed.) They knocked out all 9 windows in about half a day and took care of all the debris and old windows. My home was clean when they left. I can't recommend Glendora Window enough. I have already given their info to two neighbors. read more

Fantastic service! The shop is nice and clean with very welcoming staff to help. Messaging through yelp was seamless upon arrival to the shop.

Anthony and his crew Garrett and David provide great timely service and pricing. They are honest.

Garrett and David did an amazing job. They showed up on time and did the job in a timely manner. I would definitely recommend them.

I needed to replace the glass on our coffee table. I had communicated with Anthony multiple times via Yelp and he was extremely responsive and communicative. I shared the measurements, we agreed on a price and I drove 30+ minutes, bringing my coffee table with me (as requested) to have it measured. After another man looked at the table mentioning they needed to make a template, Anthony shares that it will now be 25% more than we had agreed ('it's a different process, etc'). I felt taken advantage of and it was dishonest - of COURSE they had to make a template, why else would I bring the table in. As I reflect, whether intentional or not, he had ample opportunities to advise me that there might be an additional charge, and he never did. It was just not professional. He also offered me $20 for my gas (which he didn't follow through on) and wouldn't give me the template (a traced copy, using a marker on a piece of butcher paper) until I reminded him of the $20. He did apologize to me afterwards and agree that he did not disclose that there would any additional costs. It's unfortunate - I really hope a lesson is learned here. He seems like a nice guy, but just didn't handle the situation well. read more

Just had one of my widows repaired (Amazon delivery person accidentally swung my gate into the window and shattered it)by Glendora Windows. Garret and David were on time, courteous, and got the job done in a timely fashion, in the time frame they told me. I called Anthony yesterday, he put me on the schedule the next day and it's all done. Anthony was easy to work with and would highly recommend their services. read more

Excellent service and quality materials. Grateful for the veteran's discount. I highly recommend this organization.

Glendora Windows replaced all the windows in my home in April '25 and since then my electric bill has declined by 25%. I have not had to cut on my air conditioner unless the temperature is in the upper 80s. I am very satisfied with the windows. They look great, the installers were very efficient and it was great working with Anthony. The only drawback was working with the window manufacturer. One of my windows was cracked and it took a few months to get the glass replaced. read more

They did a great job on my custom. Shower Door had a very good price., at a very good price.

Great service and quality work. We ordered screens doors with doggie dogs for both our patios. The installer did great clean work.

Their quick professional service was appreciated. My glass window was broken on Saturday. Estimate on Monday fixed by Wednesday. Anthony had great customer service and communication. The installers explained the process and were extremely professional. Made sure to clean up like they were never there. The price was also a few bucks less than another quote. read more

Double paned glass in a sliding glass door that was installed by another company in the 90s got stains in between the glass, so the glass always looked dirty. The doors were a wide oak trim. Glendora windows did an excellent job replacing the glass. They were careful and very neat and personable. I was extremely happy with the outcome. read more

If there were 10 stars I would have given it! World Class Customer Service from beginning speaking with "Jack" (Jackie) to both installers Earl (owner partner) and Ben who installed my replacement windows. I just cant say enough when the thought of good customer service was dead. read more

My very exuberant large puppy accidentally busted my window in my bedroom. Going after something I'm sure he thought was very important. I contacted Glendora window and glass here on yelp. Anthony got back to me right away. I was able to remove the glass frame and bring it to him. I have old aluminum windows. So that saved me a home service charge. He was able to get it done in no time. Now I don't have a ghetto window anymore, thank goodness. read more

Service was fine. Work was fine. Workers were courteous. They take venmo which is nice as initially they wanted me to go to their office to drop off payment as the installer won't collect payment. They didn't clean up their mess and left a wall looking worse than when they arrived. read more
