I am the president of an 8-unit coop building in Brooklyn. Adler replaced every window in our building (60+ windows) for us in Oct. 2017 and we were entirely satisfied with the entire experience. The installation crew was careful around personal belongings in each apartment and the cleaned up thoroughly each day. As soon as our contract was signed, I had access to a project managed to coordinate the project and I was in direct communication with the field supervisor who was on site every day during the 2-week installation phase. The entire project was completed on time with minimal disruption to our daily lives and with no additional or unexpected costs. Everyone in the building is extremely pleased with their new windows and the entire experience with Adler. I would highly recommend Adler to anyone who is considering a building-wide window replacement project of this size.
