Very impressed with Ecoline Windows from booking to ordering to install to enjoying the finished product! I requested quotes from 6 different companies in Calgary to provide me windows to meet the Canada Greener Home Energy Program specifications, and this was 1 of 2 companies who could deliver, so that I received the maximum rebate eligible per window. The Ecoline total price was the middle of the quotes, yet I get my rebates, and this brings me below the quote of a competitor. Professionalism all around--Alexander H. was courteous, honest and very professional in the assessment. The booking of appointments was quickly done by office staff. Addressing questions as to when the install may occur was thorough and they were patient with my questions. The installers, Alexei and Slava were very courteous and polite, worked hard to install and get the job done on time, tidying and cleaning debris into piles, sweeping and vacuuming as they left a room. Time of booking to installation was about 4 months. Competition in the marketplace is good, but why waste your time when Ecoline delivered on all aspects?
