I ordered five windows, four came out fine. The fifth was supposed to allow fire escape access from the kitchen. After long discussion about various options they proposed one opening inward, and in the rendering it opens around 60 degrees, which the managing agency and I approved. However when installed it opens around 10 degrees, hitting the stove, not allowing adequate access, which they should have realized. I paid for four windows, but not the fifth. Now they are threatening to sue me, though I don't see that they have a good case.

The team that day were cold unfriendly and bizarre, except the woman, thank God. I gave her a small present. They talked to each other rather than me and were cold towards me. They removed my shades did not reinstall them - and a giant AC and did not show me how to operate the windows. One of them told the head of the crew to show me how to adjust the windows and he replied, "she en go tilt no window" as well as " I ain't commin back here" without looking at me.
I made one small request to cover the heater, and the vibes- I felt like I would be yelled at - so this phenomenon they were exhibiting is called assuming the worst about someone based on prejudice. I was very polite to them. I would never recommend any unkind unprofessional lack of emotional control groups of people to go to anyone's home.

I am an Interior Designer and had done two corporate projects for my clients who owned their condominiums where Adler Windows provided and install their windows. My projects went seamless and because of this, I later recommended them to my friends who were in need of new windows for their homes. I would highly recommend them. Kathleen Peragine

Adler Windows was great from the start. They responded to my initial inquiry quickly, easily scheduled a visit for an estimate, allowed me to arrange to come view the window options in person in their show room, worked with my building (co-op) to get the project approved, and scheuled/installed quickly, on time, on budget and with minimal disruption. They worked very neatly and were very considerate of my space and my personal belongings. I highly recommend.

We used Adler to install windows. They did a good job on the install and the price was competitive. Sadly, we have had several problems with the windows and it's like pulling teeth to get them to respond and fix the problems. It takes several phone calls and emails to get them to reply. They do not follow up and as a result we would say this is a company you should avoid. They are not professional or caring.
