The Alpha Glass team is exactly what you want from a vendor. Good price, good communication, good workmanship. I heartily recommend, and if I ever need glass again, they'll be my first call.

Fantastic 4 person team replaced glass in some of my existing windows and replaced entire windows in two upstairs rooms. Fair quotes, knowledgable, great ideas to make the project better. Gave exact timetable, showed up on time, worked quickly, and reviewed the work to full customer satisfaction. There was no big sales production with Alpha Glass. No sign today and today only for the discount. Alpha Glass is an exceptional company from start to finish. The feeling of honesty and Professionalism began when I met Evan through the team leadership with John on the project. They took the time to review the project and provided a fair estimate allowing me to review what they are proposing and agree. They worked together well, were sociable and friendly, and respectful of my home. Below is one of the fantastic widows they installed.

Fixed our window in a couple of days after I called for the quote for 1/2 the price of my other quote.

Skyler and Marcos came to install three windows in my condo that had broken seals. It was not an easy task because I’m on the fourth floor. Not only did they install the windows in under two hours, but they put the furniture back, cleaned the windows and vacuumed.They left my condo looking perfect.Both were very professional and personable.I would highly recommend Alpha Glass and Window.

Mike and John stopped by the Salvation Army Denver Red Shield to repair a slightly broken glass in a youth classroom. Not only were they very efficient, but also respectful, personable with genuine vibrations. HIGHLY RECOMMENDED! Our team values your service and look forward to working with you again. Blessings!

Mike and John arrived to provide us with an estimate for the glass, which was more affordable than a competitor’s bid. Once the glass was ready, they communicated the installation date. They arrived early for the installation and cleaned up after themselves before leaving.I have used Alpha Glass at two buildings that I have overseen and they have done excellent work at both locations.

22:39 10 Mar 25

The whole process deserves 5 stars. Phone interaction with Evan, the bid process, the installation with Mike and John, all done timely, and neatly. Thank you Alpha Glass for a 1st rate job!

00:25 01 Mar 25

Absolutely a five star job and company. I wish there were 10 stars. John and Mike are a great team. They showed up on time, they are courteous and polite gentlemen. Professional in every respect. They got straight to work and did a superior cleanup after the instillation. They represented Alpha Glass in the best possible way. I will recommend Alpha Glass to everyone I know who may need a superior glass company to deal with. 👍👍👍👍👍👍👍👍👍👍👍👍👍⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️Bryan schultz

18:39 24 Jan 25

Would highly recommend Alpha Glass and Window! Got my job done sooner than expected! Pricing was fair and very reasonable. Marcos did an outstanding job and was very pleasant to work with.

00:23 19 Jan 25

Courteous, friendly, on time, did a great job. What else can you ask for?

17:24 15 Jan 25

This company is great! They did an excellent job installing my custom windows and sliding glass door. Evan and Mike we very professional and proficient.

20:45 10 Jan 25

Alpha glass was super responsive, prompt, gave a fair quote To fix a broken garage window, and did a beautiful job. These guys are super nice… on top of it all!

16:52 12 Dec 24

Just had a window replaced by Evan and John. They were both quick and professional. I would definitely use Alpha Glass in the future and would highly recommend them and their team.

18:49 06 Dec 24

Marcos and Michael did a great job installing our window and used so much precision to ensure that there was no issues with it in the future. Great people too!

14:40 06 Dec 24

I recently had two picture windows installed by John and Marcos from Alpha, and I couldn’t be more pleased with the experience. From start to finish, they were pleasant, polite, and thoroughly professional. They kept me informed throughout the process, providing updates on progress. Also worth nothing, I work from home, and namely in the same room as one of the replacements. At no point was there any recognizable annoyance or discomfort with me being in the same room where I could observe the work.During the planning phase, I had l discussed with the project consultant and front office about replacing a piece of wood around the base/sill. Although this detail didn’t make it onto their instructions for the install, John and Marcos handled it with class and imposed no guilt on us for the clarification, despite an obligatory, unplanned trip to Home Depot and some extra time required.The work was done at a much more reasonable price and with much more professionalism (but with the same level of quality control) as some of the higher profile names touted as best in class (e.g., Renewal).I will definitely be working with Alpha for my next window project and would highly recommend John and Marc to anyone looking for a smooth and high-quality installation experience.

Evan and John did a great job! They were fast but did quality work. We only had one window pane to replace and it only took half an hour from beginning to end. Thanks guys! Hope we don’t need to call again, but if we do, it’ll be you. 😁

20:26 15 Nov 24

Mike and John did a great job repairing my glasses shower door. They came on time, quickly completed the job and made appropriate changes to help ensure the glass door was secure

21:16 29 Oct 24

have had them over to replace multiple windows on our building and have been great and speedy every time.

20:22 28 Oct 24

Happy with my experience. Had a Pella window break. The quote from Pella was insane and I had 2 other glass companies tell me they couldn't fix it due to the design of the window. Alpha got it done at a reasonable price.

17:05 23 Oct 24

Evan and Noah did a great job with our window replacement. On time, courteous, and professional. 5 Star!

19:04 22 Oct 24

They did a great job. Took measurements of the window, ordered it and had it installed in less than 2 weeks. Super seamless process and great customer service.

21:19 02 Oct 24

We had hale damage about a year ago and finally got our windows fixed. We were so pleased with Alpha Glass and windows. They came on time , did the work and were professional Mike was great as were the other team members. My son also used them. I would highly recommend them for your window and glass needs.

18:51 30 Sep 24

Mike and Zach did a great job installing a large window on the second level of our house. Alpha Glass provided the glass I needed at a competitive price and good quality installation.

15:48 30 Sep 24

These guys did a good job. They were fast and cleaned up making the window nice and clean. I will call them again.

Mike and Zach were great! They were helpful, kind and personable. Thank you for fixing my windows!

14:49 08 Sep 24

Evan, Zach, and Mike did a great job with replacing several windows on our cabin. We had really struggled trying to find someone to do the job. Not only were they willing to do the job - but they did it really well too. Thank you!

21:09 04 Sep 24

Mike and Zach were punctual, efficient, and effective. We figured the job would take a couple of hours but they removed our old damaged window quickly and installed the new window in a flash. I think that they were in and out in less than an hour. They thoroughly cleaned up after they were done with the install as well. It's like they were never here. Great work.

19:18 20 Aug 24

Alpha Glass was great! Great communication, very professional and excellent service. Mike and Zach were great too. They went above and beyond to make sure the window was clean and furniture moved back into place.

19:50 14 Aug 24

Mike and Zach fixed our window yesterday. It was a small bay window in our kitchen that was damaged 1 1/2 years ago from a hail storm. They were both very nice, professional, and efficient. I would definitely recommend them!

18:39 08 Aug 24

Zak and Mike great team, very professional in and out in about 1 hour; another pleased customer. Thank you Guys.

00:09 08 Aug 24

What a great crew!Michael and Zach set our shower glass, super clean and super fast. Very polite young guys, knew what they were doing, definitely calling Alpha for our next glass project!

17:07 07 Aug 24

We had a shower glass door which shattered and needed to be replaced. Mike and Zach came out and got everything fixed up for a reasonable price and we were very happy with the service. I would use alpha glass again.

20:31 02 Aug 24

Zack and Mike did great work on our front office window. Even though the frame of the building itself had shifted and the window opening slightly off square, they were able to order a custom glass piece and fit it to perfection.

17:58 31 Jul 24

Absolutely amazing work!!Zach M was professional and very kind!!I highly recommend this company and Zach M!!!👍🏻

I 100% recommend Alpha Glass and Window! Their prices are reasonable and the customer service is top notch.The installation team, Zack and Mike, were kind, on time, very professional and did a great job with the installation of our shower glass as well as the restoration of our large living room windows. They walked us through every step of the process and made sure we were satisfied before leaving the job.I will be recommending Alpha Glass and Window to all our friends and neighbors!

21:59 01 Jul 24

17:24 01 Jul 24

Good customer service and competitive pricing. Re-glazed two windows faster than I expected and that was appreciated.

22:38 07 Jun 24

Alpha Glass took my order on Tuesday to replace two foggy windows, three days later on Friday they called and said they were on their way to install. I was shocked, because I thought it would take at least two weeks.Zach is the tech that gave me the quote, and he installed the windows, and answered all my questions about tinting windows.Alpha Glass and Window Company is very professional, and I will use them again.Lauretta

I am the Building Engineer for a luxury condo association in Cherry Creek. Some time ago, we had "clamshell" damage to our very large glass entry door to the lobby. We sought to get quotes and Alpha Glass was the ONLY company among many that would agree to do the work. Their price was competitive and there service was amazing. We later opted to change the pivots on these same doors and Alpha Glass took care of everything including tracking down this very particular hardware. Michael and Zack were professional, friendly, and very efficient. Can't speak highly enough about this company.

22:41 15 May 24

The team at Alpha Glass was really easy to work with and did a great job. The installers Zach and Mike completed the install on our shower glass quickly and did a great job. I appreciated their positive attitudes as we asked them a ton of questions. Thanks again!

05:33 15 May 24

I'm sorry it took so long to write this review! I have a huge heavy glass sliding patio door (97" X 98" ) that needed repair. Most companies didn't want to touch it and be responsible if something happened. Marcos and his team were able to do it professionally and safely with ease. I'm reaching out again to do some more business with them.

16:12 01 May 24

So impressed with Evan and Mike. They replaced a glass window in my home. They showed up on time, worked efficiently and the results were beautiful! Thank you Alpha Glass and Window!

20:21 26 Apr 24

We have big retail windows at our sports bar and needed 2 replacements after a wild weekend. Alpha was punctual in all facets from finish to start. Quality work and wonderful to work with. Zero funny business, solid all the way. We are happy to be back to normal and looking good! Thank you, Alpha Team!

14:30 24 Apr 24

Alpha is a great glass business. Great profits, fast, and great workmanship !

14:18 16 Apr 24

Timely service and followed through with exactly as promised.

19:47 05 Apr 24

I had a (finished) basement bedroom window broken by a huge slab of 2 feet of wet roof snow blowing out a window well. Alpha gave me a free estimate, showed up on time to the minute, completed the job in 90minutes, and removed the broken glass from the bedroom carpet.I would not only give them the highest available rating, but also plan to immediately give them a call if/as/when I have any window issues in future.

16:53 04 Apr 24

Exceeded expectations!!! The other glass place I called said no need to make a house call to assess a settling shower door. Advised the only option was to fabricate a new one, which would be a minimum of $1000. I called Alpha Glass & Window, resigned to the fact that I would need a new door. Tech fixed it for the price of a house call, took measurements, and promised to keep them on file on the outside chance it settles again, so we can fabricate a new one if needed, without another house call!

I’m doing a remodel for a customer and during construction one of the windows was broken. The tech that came to measure my window was punctual and polite to the homeowner. He was professional and prompt. Thank you Marcos, much appreciated.

16:17 20 Mar 24

They replaced a window in our sunroom- they did great work, quick and friendly! Highly recommend!

18:43 23 Feb 24

Alpha glass was amazing to work with. Everything that was promised they delivered on. Marcos the installer did a fantastic job and went over all do’s and don’t’s, also what the warranties were on everything. Shower door looks great.

18:04 08 Feb 24

They did an amazing job replacing a specific window that my HOA required. The price was fair and the window looks really good. But what I really appreciate is how quickly they finished replacing my window. Would go with them again for my future window replacements.

We've been referring Alpha Glass and Window for years to our clients. They consistently have great pricing and the communication is just as good. And when things don't go 100% as planned, it's about how it's handled. In our case, when we had an issue with our window that needed to be resolved on our personal residence, BOOM, Alpha handled it beautifully which we greatly appreciated! Definitely give them a shot at your next window or glass job!

17:55 23 Jan 24

When I think of Alpha Glass, I think about hustle. Professionals that work hard and get the job done. I’ve known Skyler in a professional capacity for a few months, and he’s 100% keyed into the needs of his business and his customers. I can’t speak to the actual glasswork of this company, but if their internal dynamic is any reflection to their work, this is where my money would go.

22:36 18 Jan 24

A beautiful new window at a reasonable price. Alpha Glass and Window has staff that are easy to work with and! they respond. I was referred to them and am so happy! 🤩

Alpha Glass replaced a large picture window in our nook. The installers arrived slightly ahead of schedule and were very courteous and professional. They took care to clean up after the install, leaving the area in great shape. I highly recommend them and will use them again.

16:10 19 Oct 23

We recently had the glass in a large picture window replaced. Other businesses told us we would need to replace the entire window. Our crew of Marcos and Evan did a great job, working quickly and addressing a previously unknown underlying issue. I will use Alpha for all future glass and window needs.

22:06 14 Sep 23

These guys are great. Replaced a broken glass shower door and 3 windows. Very professional and highly qualified to do window services. Would highly recommend. 5 ☆

Skyler, Marcos and Ryan were very thorough, knowledgeable and efficient. Will definitely be reaching out to Alpha Glass again in the future for any work I need done!

21:00 02 Jun 23

We recently had Alpha come out and replace 4 huge windows in our a-frame. This was after one of them cracked from top to bottom, and they very quickly put us at ease that it wouldn't get worse before the replacement.They did a really thorough job coming out for the estimate and measuring everything, and also answering all the questions we had. They got back to us in a timely manner with the full quote, and came in much more reasonably price wise than other vendors we talked to.They had to custom order the windows and it took a few months before they did the job, but remained communicative. When it came time for scheduling, they explained the process and what the time commitment would be. The work actually took 2 days instead of 1 due to rain, but they were very thorough and quick to schedule the follow up day.The crew was super friendly and accommodating. They answered questions throughout the work sessions, and were very efficient and clean.100% I recommend working with Alpha Glass. We did another window and sliding glass door replacement a few years ago with a national chain and the experience was nowhere near as good as this one. Support this local company, they will really impress you.

21:20 29 Mar 23

Very fast response to replacing the shattered glass on one of my sliding patio doors. The doors are old, so it was a challenging repair. The techs, Marcos and Evan, did an excellent job installing the new glass panel and made sure the door worked properly before they left. I highly recommend them. Thanks to the entire team at Alpha Glass & Window!

20:16 08 Mar 23

Alpha Glass replaced a beveled mirror in a wooden frame for us. The mirror was cloudy and always looked dirty. They did a beautiful job and their customer service is outstanding.

21:08 22 Feb 23

They ( Evan & Marcos) from Alpha Glass came to my home at the designated time and were very friendly! They worked diligently until every window was sealed! What a difference this made to our home and we were not so cold during this new storm! Evan also gave me a tour of the work completed to make sure we were satisfied! Excellent work, super nice guys to work with, would absolutely recommend them to work at your home! Thank you Alpha Glass & Window! Laurine Piper

Very pleasant to work with. Smart and efficient.

00:37 13 Jan 23

i recently had several glass companies bid on a custom glass shower door and panel. Alpha was the only one that laser checked the shower to make sure everything was plumb and level. Heather worked her magic to get me a great price. Installation went smoothly, Marcos and Evan were polite and professional. I recommend and would hire again without hesitation.

Alpha Glass was amazing to work with and made the process so easy! May daughters window broke in her room Thanksgiving weekend and they came out and measured and ordered the window right away! The customer service was impeccable from the scheduling to the techs measuring to them coming back for install! Highly recommend Alpha Glass for any glass needs! They will be my first phone call next time!

19:24 28 Dec 22

The team at Alpha Glass did a great job repairing some windows in our basement. They were quick, efficient and left our place nice and clean after they were done.

19:18 15 Dec 22

Words to describe my experience with representatives from this company include; responsive, knowledgeable, professional, flexible and trustworthy. I have not had the necessary work done as of yet, but I will 100% use them when I am ready!

04:47 01 Dec 22

It’s always tough searching for a good company to help fix these random issues that come up. I got very lucky I stumbled across this company. Customer service/communication is top notch. Awesome people to work with. Tough to find these days. I hope you all can continue to help give this company some work. They deserved it.

21:21 29 Nov 22

Great company to work with. We had them install our gym mirrors for our house and they are amazing. So professional and Informative from start to finish!

Heather helped me with some difficult to find windows for my spa and was friendly, knowledgeable. She continued follow ups until everything was as promised - she is on her game!!

Great service! I am very impressed by Alpha Glass from their friendly and responsive staff to their haste in completing the job. Our glass was on order for a few weeks and the day it arrived they were out to complete the installation. Would highly recommend!

Alpha Glass did a great job with their customer service, install and repair. They were quick, easy, and fix the problem at our church right away. Highly recommend.

Installed a custom frameless shower door today. This homeowner upgraded from a metal-framed enclosure to a sleek, modern glass design. Frameless shower glass creates a more open feel and is easier to clean than framed options. Proper installation is key for a secure, long-lasting fit!

Skyler V. Checked in 30 days ago

A customer had a cracked window pane from storm damage. We measured, sourced a matching glass type, and installed a perfect replacement. No need to replace the whole window—just the glass! If you have a broken or shattered pane, replacing the glass restores safety and insulation.

Marcos C. Checked in 30 days ago

Just finished replacing a foggy double-pane window for a homeowner. Over time, broken seals let moisture in, causing condensation between the glass. Now, with a new energy-efficient unit installed, their view is crystal clear again! If you’re dealing with foggy window glass, a replacement is the best long-term fix.
