Our experience overall with Energy One Windows was good. The crew that came to do the installation were very knowledgeable. They finished the job in one day that really pleased us. We didn’t have any issues with the installation and we are very pleased with the look of the windows and how our house looks much nicer with the new windows. We are pleased with this project and everyone from Energy One. These new windows seem to keep the rooms a little cooler as they don’t get as hot as our original ones did, noise levels from outside reduced by more than 25%. Not sure yet about our power usage yet but l look forward to seeing if our usage is lower. We would highly recommend Energy One Windows they did a great job.
