Promar Exteriors recently installed windows in my older home in Downers Grove. I am extremely pleased with the windows and with the excellent service from this company. This was the first time that I contracted for exterior work on my home. Selecting Promar Exteriors was the best choice. Sales showed me several types of windows, not just the most expensive ones. We discussed the benefits of each and I selected the windows that met my needs. The installers came on time and did a excellent job installing. The work was completed in the most professional manner – they took any waste from the job and even vacuumed the work area.
