Windowtech installed a window for me about two months ago and has certainly exceeded my expectations in customer service quality. Specifically Windowtech well exceeded my expectations in terms of Responsiveness, Assurance, Tangibility, Empathy and Reliability which are five components that make up SERVQUAL model, a model used in customer service/marketing industry to measure customer service quality. Based on my experience, Windowtech is the best company in terms of customer service and quality of workmanship not just in Doors and Window market, but in the entire Construction industry and one of the best companies in all industries that I have dealt with. Their customer rep guided me and communicated with me from start to finish and even followed up with me after window was installed. They genuinely cared to do a great job and made sure all my concerns are addressed. The fact that Windowtech not only provides lifetime manufacturing warranty of their products but also provides lifetime warranty of their installation service is a great testament of their service quality. Finally, they provided all their services at a very competitive price. I have already recommended Windowtech to my friends and family and would definitely recommend them to anyone reading this post. My special thanks to Slade, Tony, Ken, and the rest of Windowtech team for all your efforts and dedication to create excellent customer service experiences for your clients.
