I interviewed many vinyly windows installers. Upon comapring the prices, presentations, professionalism and references for all, I am glad I made the decision to award the contract of changing all the windows of my house to Promar.
The installation crew was hardworking and professional. Their leader (foreman) lead the crew to be through in their job.
This installation occured in early summer of 2012, so I still need to experience the new window experience through wonderful Chicago winter. But, I am not too worried about it, since Promar has given 5 years warranty on their service.
