Testimonials

“I am very very pleased with my window installation 3 days ago. Installers were nice & polite. Seems like they were working in harmony. David made sure everything was neat & clean and back in order. Awesome job, I would recommend Guardian Windows to family & friends anytime.”


“Marti’s team were great when they installed our new replacement windows. They completed the tedious job of tearing out the old ones, prepping each opening, installing the new windows, and even caulking, to insure a good fit. They were efficient, neat, clean, and very careful around our home. The windows are beautiful and it is such a pleasure to look outside now, knowing that I can open them with no trouble and I also feel good about their energy efficiency. What I good choice, to use Guardian Windows. They have been is business since the 1980s, so I felt comfortable that they knew what they were doing. Great customer service!”


“For the last two days, over the noise of breaking glass, I heard the team from Guardian Windows talking, solving problems, laughing and working together so seamlessly, it was impressive! “Extremely conscientious” are two words that come to mind. They did a beautiful job and I’ve never found one sliver of glass left behind. Outstanding!”


Guardian Windows installed our windows in May 2010. We have a two story house and they completed the job in a day and a half. They were very neat and did not leave any debris behind. We are very happy with the windows and believe they helped reduce our electricity usage even though this was one of the hottest summers in Houston’s history.”


“Researched Guardian Windows after listening to several “loud” window companies with their not so perfect products (read reviews and BBB). Marty carries what really perfectly fits an older house; the right brands + quality + looks. Great workmanship by installer. I am picky, and it paid to research.”


Windows were ready quickly, installed when we needed them, and look great. Everyone we met in the process was helpful, polite, and friendly. Great job!


Crew was on time, got the work done expeditiously and cleaned up after themselves. Windows look great.

I have ordered windows from Guardian Windows for two of my rent houses. They were a great price, good quality, and the installer was neat, clean, and very careful not to damage existing walls. The windows were installed in the time frame I was given. I have been able to charge more in rent because the windows upgraded both houses. The windows are energy efficient. Sturdy construction makes it hard for anyone to open the window when they are properly locked. This has helped with safety. The next house I renovate I will call again to purchase windows from Marty at Guardian Windows.


The owner, Marty, was so helpful!He was very knowledgeable. The window quality is amazing! Worth it!


Thamks for all the help on my windows. You guys did a great job. I am glad I choose you over the low ball companies your quailty is far better. You were not the highest bid and not the lowest,but you were one of the best.


I am so excited about my new windows and sliding door that were installed today by Guardian! I hesitated for months to commit to a company for this job. I just did not feel confident in the several other companies who I interviewed to do the work. I definitely made the right decision to hire Guardian. The crew arrived on time this morning and were very hard-working, professional and obviously knew what they were doing! I have complete confidence in this company and will definitely recommend them to my friends, family and neighbors!


My windows are beautiful and compliment our home perfectly. They reduce heat,cold and moisture that entered our home before. I am completely satisfied with the job.


I kept putting off the task of replacing my windows. Just didn’t want to deal with a bunch of salesmen. After getting several estimates and doing my homework, I signed a contract with Marty who is really the “owner” of his company. I am now enjoying my beautiful windows and it was painfree.


You said you were in buisness since 1986 and had amazing crews. I have to agree you a have great windows, at a very fair price I belived you when you said you offer the highest value for the money. Ron and his crew are outstanding. I have never had such an enjoyable and quick remodel done on my home. They showed up at 7am and were done by 2pm.just like you said. Thanks for you help in solving my window concerns.
