10/10

My house windows were 20 yo and drafty. EchoTech windows were not the cheapest but the best in my opinion. They offered lifetime warranty on labour/ installation , parts and hardware. Forgot to mention that they look nice too!!! The installation crew led by Andrei worked like Swiss clock. No mess, no fuss. Very satisfied.

Derek and John were on time on he job. They were quiet and efficient. They cleaned up after themselves - vacuumed the area where they were working and did such a good job, I wanted to ask them to do the whole house :) They answered all of my questions - honest and professional. I recommended GNI to my friends. Thank you
