“When we bought our house, in the entryway there was an accent wall with cool 80s decorative mirror glass that matched the cool 80s chandelier by the front door.....and then a couple years later my husband accidentally broke the glass. The Glass Guru helped us with finding and installing an even better gold decorative mirror glass to replace it with. They were very easy to work with and very accommodating of our weird schedules. Jennifer helped me pick out the glass and Mark and Howard did the installation. It looks amazing and now we have a wow factor again when entering our house. I definitely recommend The Glass Guru for all of your mirror or glass needs.”

“Loved the service I received from the Glass Guru team. The mirrors were measured and beveled very happy with installation from Mark and team. Would highly recommend!”

“We had a shower door and a mirror replaced by The Glass Guru, and we are so pleased with how they look. The turnaround time from when we contacted them, to getting an estimate to install was incredible. Our installer, Howard Jeffers, was friendly and professional and he cleaned up after he completed the job. I highly recommend The Glass Guru and Howard Jeffers.”

“The entire experience was great. We had a new window within a few days at a good price. Mark Henderson and Howard Jeffers were our installers and they were in and out within 20 minutes. The new window looks great. Highly recommend Glass Guru!”

“These guys did a great job for us. We had seven windows that needed repair. They showed up when they said they would (a few minutes early) and gave fast, friendly and professional service. The windows look great. Would definitely recommend them to family or friends.”

“Great experience from this company from measurement to install. Mark Howard and Blake were very friendly knowledgeable and quick with getting window glass installed. Will definitely use again if need to.”

“We recently had a frameless shower glass door installed along with two tub/shower combo sliding glass door kits by The Glass Guru, and the entire experience was excellent from start to finish. The whole project only took about 2 weeks and required just two visits — one for measurements and one for installation — which made the process incredibly smooth and convenient. The quality of the work is top notch, and everything looks amazing. The installers were professional, efficient, and paid attention to detail. We are extremely happy with the final result and would highly recommend The Glass Guru to anyone looking for high-quality glass installation work.”

“The Glass Guru did an excellent job replacing the shattered glass in this door. The door manufacturer claimed we'd need to buy a whole new door but The Glass Guru replaced the glass insert with a perfect match. Highly recommended.”

“We built kitchen cabinets and needed glass in the top 7 cabinets and in our dining/bar cabinet. 2 of these paneled were tempered, decorative glass. Mark Henderson was our installer. Mark is a very sweet man who has obvious experience in his job. Everything was flawless. It is important to support small businesses, and this is a good one! Glass Guru was very timely, efficient, and fair on price! They did give us a free estimate.”

“Mark Henderson and Howard Jeffers took phenomenal care of measuring and installing glass for an outdoor table top for us. They were fast, professional, and on time. Very friendly gentlemen that we look forward to working with on our next Glass installation that they have already measured for. Highly recommend and not only would I use them again, I already am!”

“Howard Jeffers replaced the glass on our bedroom slider today, and we had a great experience! He was very nice, professional, and got everything done really quickly. The whole process was easy and stress-free from start to finish. We really appreciate the great service and would definitely recommend him!”

“I would use Glass Guru every time! They came out to do an estimate quickly and my window was replaced on time as they stated! They even worked around my busy schedule. The installer Howard Jeffers was courteous and worked quickly. I’d recommend them 10/10”

“Glass Guru was highly recommended by our neighbor and our Roofer! They provided an explanation of what they were going to do and gave us a competitive quote on-site. They said the replacements would match the other existing windows and would be ready in a couple weeks. A couple weeks later, they called, set up an appointment, came over (and wore booties on their shoes as my wife was refinishing our floors at the time) and efficiently installed the replacements and cleaned up after themselves. They are beautiful and match the other existing green-tinted windows perfectly! I highly recommend them!”

“I went off of the reviews and chose Glass Guru for my bathtub glass. Everything is true--they are responsive, professional, friendly, well-priced. You cannot go wrong in choosing them to take care of your home projects.”

“Great craftsmanship and design on our frameless glass shower. The first time the fixed glass was cut incorrectly. Mark without hesitation reordered the glass and had it reinstalled. This is that makes this company spectacular they stand behind their workmanship and reputation. Great Thanks”

“Mark Henderson and Howard Jeffers and their crew did a great job replacing multiple windows. They went above and beyond fixing our front door window and left the house spotless. Thank you! Highly recommend!”

“The Glass Guru Team are true professionals. They ordered the glass, scheduled it as soon as it arrived, professionally removed the broken glass without leaving a trace and installed the new glass. No issues! Everything went smoothly!”

“Reached out to the glass guru for a window repair and they were flexible with my schedule. They came out and with no hassle or excuses got the job done in 30 minutes. Blake and Mark were the techs. They were both great, knowledgeable and mostly importantly left the area clean like nothing had ever happened. I will recommend the glass guru to anyone!”

“I have a unique shaped window that I thought would be really difficult and expensive to replace the glass on so I put it off for a long time. I finally decided I had to do something about it so I called Glass Guru. They were very professional and responsive and their pricing was reasonable. Mark and Howard arrived early, replaced the window easily and cleaned up after themselves when they were done. I should have called them a long time ago. A+ company!”

“It was such a pleasure dealing with Jennifer, Mark, and Uriel at The Glass Guru in Montgomery, TX. Mark was such a professional when he came out to look at the project. I wanted a shower door with the rollers at the top. He designed it to my specifications. Uriel came out and measured it to get the exact dimensions for the door. I wanted a vertical handle and he made sure that it was placed as close to the edge of the door as possible. That way it gave me a bigger opening when sliding the door. How thoughtful was that! They were all very professional, from my initial contact with Jennifer through the installation by Uriel. If you're looking for a reputable company to install a shower door, look no further. The Glass Guru is it!!”
