We've had to replace all windows and doors in the rental unit we bought recently and had 5 companies quote on our job. The first guy missed a window on his list and came up with a funny number. Then we saw Dimitri and found him very upfront, knowledgeable and convincing. Then we saw another big company rep. trying to persuade us that 11800 was the greatest sale price ever and we'd miss it once he was gone, etc. The last 2 quotes seemed reasonable, but of all those people Dmitry impressed us the most. He heard every word we had to say and was very clear and convincing in his recommendations. His offer was at par with the best. And so, having read the reviews, we chose Aztech and never regretted our decision. The whole experience went exactly the way we were told in the beginning. The installation was scheduled 3 weeks in advance, the installers showed up on time and impressed the heck out of us with their work. We could believe our eyes when three guys were done replacing 9 windows and 2 doors by 4 pm! Everything looks beautiful, the electricity bill is down by $35 the very first month!! Couldn't be happier. Thank you Aztech.
