On time and efficient

Marty came to the house to give me an estimate and answer questions about the product. Within a couple of days, the windows were measured and in production. On the day of installation, Ron Hopper and his crew were at my house exactly at the time they said they would be here. They explained the process to me and started in. They were respectful of my home and property. They cleaned up everything and made sure that all was back in place and done to my satisfaction before leaving. They had my new windows sparkling and ready for me to enjoy in just a few hours. I am very pleased that I chose Guardian Windows and recommend them highly. They even gave a follow-up call to make sure I was happy with the windows and the work they did.

Excellent installation

Ron's team did a fantastic job. They were on time or early each day, and they did excellent quality installations. They were efficient and worked great as a unit. They cleaned up after themselves and left little trace of having been in the home at all. Would absolutely recommend them again.

The Best Ever

The installers were on time and such a great job that I was amazed. They were so professional and you could tell they knew what they were doing. The treated my home as if it were theirs. They even windexed my new windows and cleaned up after the installation. They covered everything before starting too. Their personalities were great and I felt very comfortable around them. They went above and beyond any expectations I might have had. Great job and I cannot wait to use them again for my next set of new windows.

Great Company, Great Windows

After looking through dark solar screens, listening to outside noises and feeling cold wind through my windows, I decided to invest in energy efficient windows. In June, 2011 I had 3 estimates for windows and decided to go with Guardian Windows after researching the companies. I love my windows as they look great, I can see outside clearly, plus even the noise of storms is muffled and my energy costs are very reasonable even with the very hot summers we have had. Also, my furniture and fabric is not faded anymore. Ron's crew installed my windows. They were very professional, friendly and installed each window and cleaned up after each installation. I had 19 windows installed in 2 days. The crew showed up early and finished around 1:00 each day. All the debris was cleaned up afterwards. I have recommended this company to my neighbor and my family. Both are very pleased. I have had several questions after installation and my call was returned the same day. Thanks for great customer service. Kudos to Ron and Carol. Thanks for a job well done and still enjoying my awesome windows.

None can compare!

Three years ago I selected 6 companies to give me quotes. Thank goodness I had called Guardian for a quote. They were the 4th company and I cancelled the last two companies for quotes. I got no fancy sales pitch and empty promises. I received facts and proof of quality. All of my questions were answered. He proved to me what other companies were offering couldn't match the quality of Guardian's windows. I also liked that fact that the owner of the company gave me the quote! Crew showed up in 27 degree weather and installed these wonderful, heavy duty, high quality windows. The crew was polite, friendly and experienced. I am still amazed how quiet the house is. I had to reprogram my thermostat 5 or 6 times before I got the temperature right! Prices aren't the cheapest but you can buy cheap poor quality windows at higher prices if you're not careful! Trust this company. They really are you guardian! I'm glad I waited 3 years before writing a review. One bedroom used to be so cold in the winter. You could feel the draft before you were near the window. Now my 85 year old mother has moved into that room. I like receiving referral $ when I send a new customer!

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!

Couldn't Be More Pleased

I just had 26 new windows installed in my home and I must say that if all companies performed as Guardian Windows the BBB would go out of business. The price was very fair, the product is outstanding and the work crew was very competent and professional. They were on time each day, immediately went to work and when they left at the end of the each day everything was clean. They took care with all of my belongings even moving some that they thought might be at risk. They were cheerful and professional despite several challenges. I had some unexpected areas of rotted wood which they replaced and made suggestion on what needed to be done to prevent future damage. The also cheerfully dealt with the presence of several wasp nests in a window casement. Once the work was completed and they left for the day there was no evidence that they had been there other than my lovely new windows.

Guardian Windows - Promise made, promise delivered

Marty runs a top notch business. He answered all of our questions and provided welcomed alternatives to selecting the right windows for our home. Ron and Carol were at the house the following day to measure all the windows and ensured everything was in order. The windows came in earlier than expected and the crew did a great job installing the windows and cleaning up when the job was complete. We are really happy with the windows and glad we decided on Guardian Windows.

Much Appreciated Guardian!

My new windows were installed today and I am very pleased with them. Marty gave me a great deal for the 10 windows I purchased from Guardian, and Ron and his team did a great job installing them. The installation team covered everything in each of the rooms they worked in, cleaned up and hauled away all of the old window debris, and shined each of the new windows upon installation. Thanks, Guardian!

Exceeded my expectations

We had Guardian replace the windows in our entire house (19 windows) Everything about this company is Five Star! Marty answered all of our questions. The order was filled earlier than quoted, and installers were very professional and courteous. When they left, you could not even tell they had been there ,except for my great new windows. I was amazed at how quiet my home in now, no street noise at all. I highly recommend this company.

Windows

We had Guardian Windows install 6 windows in our home. This company is one of the best home improvement companies I have ever done business with. The owner, Marty is the salesperson. He comes and measures your windows and shows you his products. He then explains the benefits of each style. After that he gives you an estimate on price and time. We purchased the Showcase single hung windows. The installation crew was top notch. I had a call from them several days ahead of time to set up the day and time. The crew was on time, fast, and very professional. I still have a few more windows that need replacing in my home. I know I will be calling Guardian Windows when we are ready to have them installed

Great service and very happy with windows!

The whole team at Guardian Windows was very professional and delivered on the promised window quality and installation. David and Alex installed my windows and did a great job replacing the old windows with new and they cleaned up all the debris. David every fixed a loose board on my hardwood floor and repaired my back door. I couldn't have asked for a better experience!

Should be 6 stars!

Everything about this company is wonderful! The owner himself, Marty, came out to measure our 40 windows. We selected Showcase windows. The installation crew was the best that we've ever experienced. They showed up on time, were so friendly and professional, and took great care of our home. They used tarps to cover all the furniture and floors. When they finished in the afternoon, you couldn't even tell they had been there - except for the fact that we had gorgeous new windows! I dreaded replacing our windows because I feared the mess and possible damage, but Guardian Windows made it a very pleasant experience. We'd give them 6 stars if we could!

Very Satisfied

Guardian Windows, Inc. installed 10 new windows in my house on June 13, 2013. This company is awesome, the owner came out and told us what the charge would be and did not try to sell us something we did not need, thanks, Marty! The installers, David and Simon absolutely professional! I don't usually write reviews but this time I had to. Beautiful windows and beautifully installed. Thanks.
