Got all new windows for my 30 year old home. HD personnel were excellent throughout the sales and installation phases of the project. They demonstrated the windows, how they were constructed and how they wuld be installed, who would be doing the installation and how they were vetted. The windows arrived earlier than promised, were installed in one day and have performed well since the install. I had quotes from other top line window companies and HD products were much more economical than the others. The installation and window wrapping process appeared commensurate with what was promised by the other companies. My only concern was the use of strips of fiberglass insulation to fill the voids between the new windows and the old frames. I would much rather seen them use minimally expanding foam. The difference in inside temperature next to the window pane during the winter months was amazing. The inside surface of the old windows was always cold to the touch, whereas the new windows seem to cloes to room temperatur on the inside. I am thoroughly happy with the product, the installation and support from HD.
