It took us several years researching the window suppliers before we chose GreenFox. Once we had seen the windows in the showroom we already knew the high quality of the products. Working with the Project Manager, Harrison, in the home inspection and planning, we were very much at peace with what we ordered. He gave us such clear and knowledgeable advice on the different options and the assistance with understanding the energy grants we could apply for. We were already sold by then. The staff were always ready to assist no matter how many times we called with questions and they kept in touch along the way. Our window installation was completed during one of the coldest weeks we had in the winter of 2022. We were worried about the heat loss during the installation but we didnt need to think of that. Those very old 11 windows each went out and the new ones were placed within minutes, with no discomfort in the house. The two very professional installers were not only the finest of craftsmen in the meticulous installation and finishing of the windows but they were perfect gentlemen. They worked that day and the next cold day with such superior efficiency, it totally sealed our satisfaction with Greenfox. Once everything was complete, there was no sign, other than the beautiful new windows that you could actually see through without heavy ice on them, that anything had happened. The job site was so perfectly clean inside and outside the house. Follow-up with our project manager sealed in our complete satisfaction. We highly recommend GreenFox Windows!
