GK Windows and Doors LLC

Guy was very helpful in me making a decision on my windows. He is very knowledgeable and gave me options to save money. I would recommend him if you need windows.

Our doors look amazing and the install team did an awesome job. I would recommend Guy and his business to anybody!

I met with Guy, who came to my home. I told him these windows were about 30 years old and what I was thinking and asked his opinion. He brought up some options I had not considered, which I selected and am so happy i did! I know have 4 new large windows with screens and a beautiful new easy-to-slide patio door with a screen that locks. These folks know what they are doing!
Guy also explained the difference between GK W&D products and others. A professional came and measured and a scheduled was set. I was alerted a week ahead of time when the windows could be installed. On that day four experienced workers (two have been with the company over eight years) showed up on time and by the end of the day I had new windows.
I must add the next morning when I looked out, the windows were so clear I had to touch one just to make sure it was there!
Do yourself a favor and consider GK Windows and Doors before you decide who to go with.

This was the most seamless home improvement project. From my initial meeting with Guy through the measurements and the install everything was flawless. Guy kept me informed and the work was completed earlier than expected. His install team was prompt, polite, clean and went above and beyond. They even helped me with tricky set of blinds that I wasn’t able to remove. I highly recommend GK Windows and Doors to anyone looking for a beautiful upgrade to their home.

Doors and windows can be a big purchase so go with someone who will work to earn your trust. After meeting with a number of providers we selected GK and have been impressed by the transparency and eagerness to make it a great experience. Our doors are great and perhaps more importantly the install was done right even when it required a little extra work.

This was an amazing experience. Sales rep Guy Berlt explained things clearly and answered every question. Our custom windows arrived ahead of schedule and the installation crew was TERRIFIC. They worked fast, arrived promptly, acted professionally, were very courteous, and even helped us put things back when a room was finished. (They were so great I offered to grill burgers for them when the job was done!) I'm not sure what more I might say ... I guess just that my wife and I are thrilled with the entire process and highly recommend Guy and GK Windows and Doors, LLC!

Wow my new double pane windows make a huge difference in my South facing all windows Arizona room. They look very nice.

The installer team was polite, very helpful, extremely efficient and professional. They only had one window out at a time and only for a short time until they replaced with the new window. For me it was a painless experience--I hardly knew they were there.

I had all my windows replaced by Guy Berlt, who is a joy to work with. It was very easy, smoth, efficient from initial contact thru a perfect installation.

I had 3 bids done before I chose Guy Berlt GK Windows. They are competively priced. They were totally professional, reliable and kept me informed every step of the way. Thank you Guy and your team for quality product and work. Suzanne James.
