We ordered 3 basement windows and 3 main floor windows from Ecoline. The main reason we went with this company was the customer service, I had ask for quotes from 4 other companies, of that 2 did not even respond to my request, 1 took 2 months to get us a quote back (by that time I had already ordered from Ecoline) and the other 1 that actually got us a quote back on time was not responsive to follow up questions. Ecoline was the only company that responded to us in a reasonable amount of time, mostly the same day. The guys installing we on time within the time frame provided, cleaned up after themselves, got it all done in one day and did a very nice job saving the old trim and putting it back on after. Overall very good company to work with. We have also purchased an entrance way door for our rental and just purchased another large window for our place. Highly likely will purchased more windows from them again for the in-laws house. The responsive customer communication and service is what really sold us on Ecoline. Also high quality products, their windows are performing much better than the Lux windows that were installed last year (2017) by the person we bough the home from, which are also double pane glass with argon gas.
