Unfortunately, we hired this company to replace windows for my home in 2015/16. Within one year of replacement, many of the windows' locking mechanisms got lost and didn’t work. At the same time, a couple of window steel channels got rusted. I contracted this company's customer service. They weren’t ready to hear my complaint. Instead, they asked me to wipe all windows and their channel after rain every time. Customer service also told me they don’t give any warranty on locks. I constantly try to talk to senior members of the company, but unfortunately, senior members are very rude and arrogant. I don’t have anymore words to express my pain. I suffered with this company. I suggest you please make sure you do your research and investigate before hiring any company. Thanks
