I would highly recommend Econoshield. The sales rep, Alex, quoted a good price, and ordered perfect windows--they look great, I notice significant outdoor noise reduction in all rooms and I'm no longer freezing in my bedroom (old window there, especially, was terrible for heat loss in winter). Dimitry was patient and addressed all my questions (I was a nervous customer). Pavel and Ernesto did the install and did a terrific job--impressed me greatly. If you have a bit of a hard time getting hold of a person at the company (and I experienced some of that) I would suggest you talk to Kelly, the receptionist (who is a gem) and have her coordinate the phone call with the applicable person. Really nice people who care about their work, supply a terrific product, at a good price, and do a great install. Thank you!
