Best window installers in houston, 5/19/2015

Ron's Crew the best, arrived on time and the work was clean. The clean up was fantastic. Had 21 windows and 2 doors got them done in 2 days.


Great Experience, 4/21/2015

Before selecting Guardian, I received bids from 4 window replacement companies and did quite a bit of research. Guardian wasn’t the cheapest or the most expensive, but I feel they gave me the best... value for my money. From the start of this process and all the way through, I felt that each person I dealt with at Guardian really cared and wanted to do the best job possible for me. Ron and his team replaced 3 sliding glass doors and 22 windows in two days. They did a fabulous job and the windows and doors look absolutely beautiful!! The team was on time both days and these guys worked hard and efficiently. These guys are definitely professionals and know what they are doing - working together like a well-oiled machine. I wish they installed kitchens so I could use them again.

Total home improvement

The windows look great and add a lot of curb appeal. I had 14 windows replaced on my one story by Rons group. These guys had a perfect system to replace the windows. I have had the new windows now for about 3 weeks and they look great. The new windows also reduced the amount of noise coming from outside. I trusted the crew enough that i could leave the house and come back 2 or 3 hours later with no worry of them stealing. They started at 7am and finished all 14 by 2pm. The only issue i had was that i found shards of glass all over the house and yard. I dont think its unrealistic to find broken. The problem i found was there was broken glass found in the shower, front room carpet, and a large pile in the backyard. I evetually picked it all up so now i dont have to worry about kids or my dog running around in back yard. Overall windows look great!

Satisfaction

I cant say anything that hasnt already been said about Guardian Windows. I was directed to them by someone in the windows business. The owner provides what he says he will and his crew does work to an excellent level. Totally satisfied.

The Best Replacement

We are enjoying our new windows installed by Guardian Windows. Replacing our windows was a great experience. Marty Scarpati came promptly and gave us detailed description about the windows and their installation. We are very satisfied with the high quality and a reasonable price of their windows.Installers (Ron and his crew) worked very professionally. It was a pleasure to watch how well organized is their installation. I would definitely use Guardian again and highly recommend them to anyone. Maria Pavlik

great replacement windows

After interviewing several replacement window companies we decided to go with Guardian. The windows are good quality and reasonably priced. The crew who installed the windows was fabulous. The arrived at 7:30 am ready to work. We had 17 windows installed and they were done by 2 pm. The crew made sure the house stayed as clean as it was when they arrived. The glass was contained if there was any breakage when busting out the old windows. The floor around the installation areas was vacuumed once the installation was complete. I would recommend these folks to anyone.

Great Guardian Windows

Guardian Windows installed 16 windows for me and did an exceptional job. When I called to get an estimate, Marty Scarpati came out promtly and gave me an detailed overview of the available windows and an estimate for the windows that I selected. His explanation was clear and precise and seeing the high quality of the sample windows he brought and their energy saving capability was very helpful. In my opinion the price quoted for these windows was remarkable, and I decided to go with Guardian. The final cost was exactly what was quoted to me at the outset and they were installed in the timeframe and parameters presented to me. The installers were professional in every way and courteous and polite at all times...really nice hard-working guys! They worked from a little before 7:00 am until 3:00 pm with only very short breaks and completed the job in one day. They have the installation down to a science...preparation of the area, removing the old windows and installing the new ones. Everything was thoroughly cleaned up before they left. They went that extra mile to be sure that everything was done correctly and did a couple of extra things along the way to be sure the job was top notch. My new windows are just wonderful, and I love the way they look. They make such a difference in the inside and outside appearance of my house. I would definitely use Guardian again and highly recommend them to anyone. Amazing job by both Marty and his crew!

Replacement Window

I needed a replacement window on my storm door. Marty Scarpati handled this so quickly and in no time at all, the installers came to replace the window. I am extremely pleased with Guardian Windows and would recommend them to anyone. I have been a customer since 2008 when the windows in my home were all replaced. Rose Mary Hettler

Great job

I was very impressed with the work they did. The windows arrived on time and David and Anthony worked quickly and professionally. They also did an extraordinary clean up job. I am recommending them to all of my neighbors. David and Anthony are both real assets to Guardian Windows. I will use them again if I ever have a need.

Love our new windows for our 30 yr old townhome

When I was considering quotes for new windows, no one else compared to Guardian in terms of service, quality, price, and ease of mind. Marty was very informative and did not pressure me with rush decisions like the other companies. The value was awesome, affordable, and the windows came very quick. The crew was very nice and experienced. The windows improved the look of the home as well as energy efficient. If I had another job, I would definitely call Guardian again for the job!

Great Windows and Customer Service

I am very happy with my new windows and the service I received from Guardian Windows. I live on a busy street and the street noise that I hear has decreased dramatically with the new windows.

Great Windows/Excellent Service

From the initial meetng with Marty to the eventual install by David and Art, I was more than pleased. I ordered 9 white windows but then changed my mind and decided to go with almond and Marty was very accomodating and was able to change the color. David and Art came out as scheduled and installed them in one day. They look great and the almond matches my exterior. I highly recommend them.

Guardian Windows--Simply the Best!

Well, it was a no brainer. Guardian had installed the windows on our previous home so when we moved into a home with single pane windows, we called Marty again. I must say with the move, I had a list of things to do but 3 weeks with single pane windows was enough for me. The sound, dirt, and heat coming in through the junk windows made my call to Marty a priority. It was nice seeing Marty again after all these years and I even had the same crew from 8 years ago. How about that for stability! Marty gives you the facts and knows his business!

Never Even Made An Estimate

I see that many people are very happy with Guardian, and it makes me wonder if my awful experience was due to Marty having a bad day. Regardless, Marty was apathetic and largely uninterested in talking to me from the moment he walked in. While looking at a sample, I asked a few questions about Guardian's warranty and what they offer that their competitors do or don't. Marty gave me patronizing answers; I listened and tried to discuss argon gas leakage and window replacements patiently. He cut me off in mid-sentence and told me that he had no interest in doing business with me because I "clearly knew more about windows than he did". He then got in his car and left. Marty called me back on the phone an hour later, and unapologetically began to lecture me about what Guardian's warranty was all about. I hung up in disgust. I have not been overly impressed with Guardian's competitors so far, and if we had just gone through with discussions and an estimate, Guardian easily could have had what my wife and I were looking for. Unfortunately, I am extremely disappointed, and I could never recommend Guardian's services to anyone after the manner in which I was treated.

Apology from Guardian Windows

I am so sorry my visit did not meet expectations. My presentation was not up to my usual standards and I am deeply sorry. I was having a very bad day and this client bore the brunt. As the reviews on this site attest, this is not my usual way of conducting business. Warranties are complicated and misleading. In my effort to explain this, the discussion went awry. Guardian Windows holds high standards of customer service and will to strive to do better. Martin Scarpati
