“The windows were manufactured in Houston, and were of high quality. They look great and were made to fit our specific measurements for each window. The installation was completed in one day, and the two installers cleaned up nicely at the end of the job. They were very professional.” On Angie's List

“Contacted Marty with Guardian Windows primarily to reduce heat that was penetrating 40 year old windows. When the project was completed, we were blown away by how much better the views were - almost better than the heat reduction. Very pleased with price, quality and service - would definitely recommend Guardian and Marty” On Google

“I waited about 1 year to write this review to see how the windows performed. I must say that I am completely satisfied. The work performed was EXCELLENT! I would strongly recommend them. The windows performed great, specially during Hurricane Harvey!” On Angie's List

“David and James were experts! They took out the old windows quickly and The new windows went up without delay. Very happy with the finished look and product. Can already tell the house is more energy efficient. Already had 2 neighbors tell how much better these windows look!” On Angie's List

"My windows are 7 or 8 years old now and I am still thrilled with the quality of the windows. No leaks, no repairs of any kind necessary. The owner and the staff are awesome. When I met with the owner, after checking out 6 or 7 other companies I finally got a true explanation on the wide variety of windows, price, quality... everything all companies SHOULD be telling the consumer but don't. An eye opening very much appreciated education about windows. Thanks, Guardian! You're THE best!" From Google

“Appx 5 years ago we replaced our windows with Guardian windows. First, the price was very competitive with other brands, actually a bit lower. Second the crew that arrived at 7:30 a.m. replaced the windows of the entire house before noon. They left the place spotless. The windows have made a difference in heating and cooling. More recently, we had Guardian replace a patio door, a single glass door and one window (only window not replaced during earlier visit). Again the crew, (Fernando, Matt and Fernando's nephew) were prompt. First they protected everything within the vicinity of the work. Just like good painters mask off everything, Fernando and his guys enclosed the work area in plastic from floor to ceiling and covered the floor with mats and tarps. Demolition was performed safely and all debris placed in trash cans or on their trailer. They were methodical in checking the rough openings for any necessary adjustments and the installation was completed. New exterior trim was added where the old had rotted. Now I have to paint. Cleanup left the place spotless. They vacuumed and swept up behind them. My wife's selection of doors is very attractive. A composite material that will not rot like the old doors I had installed myself years prior. Thank you Marty and your crews for good work and quality material. We will recommend you to others.” On Facebook

“My home is 40 years old and still had the builder grade windows when I contacted Guardian to get an estimate to replace and upgrade 8 windows. I am blessed with a 1 story home and have no windows on the West side, but the noise levels have become unacceptable. I wanted lower utility bills, decreased traffic and drive-by "music" noises and the front part that faces the North to be warmer in the winter. I had done my Google homework and knew what I wanted in a window. The owner, Marty Scarpati, came out in person to demonstrate the windows and give me the estimate. His comparison of the quality and construction of lower cost windows to his moderately priced Simonton Vinyl windows blew me away. There was no contest in my mind as I wanted the best I could afford and I am well satisfied that is what was installed today. Due to circumstances beyond Guardian's control my start date changed drastically and that was no problem for Guardian. They worked with me without censor until I was able to green light my installation. The guys arrived at 6:30 A.M. and had all the work completed by 12:15 P.M. They covered everything with plastic and used drop cloths and cleaned up pretty well when they were done. I'm confident that these windows will improve my home in all the ways I wanted and pay for themselves over time. I highly recommend Guardian Windows.” On Google

“Well, where do I begin? I love my new windows! After a long process of vetting window companies, I discovered Guardian Windows and met Marty, the owner. What a relief! He spent considerable time educating me and helping me make an informed decision and purchase and set expectations. Being turned off by other companies and skeptical at best, I signed a contract with Marty at our first meeting. What a good decision! He delivered, really over-delivered, and did not disappoint. I was quickly called by Fernando to measure my job and discuss the specifics of the process and installation. My windows arrived a few days earlier than expected and here is where their professionalism really shined. My installation was not the easiest due to accessibility of one window. They worked diligently to ensure my job met and exceeded my expectations. My home was respected and left as clean as they found it. Here’s the best part. Companies always say we want you happy and we will stand by our work. They did! I had a spot that needed recalling and they came out almost immediately to take care of it. Thank you Marty, Fernando and the Guardian team!” On Angie's List
