After years bearing my broken back yard sliding door and old front door, I decided to replace both of them. I quoted few contractors. I chose Aztech because of a good kick-off conversation with Dmitry and his competitive price. I have to say I made right choice. At the beginning, I knew the job in my house wouldn't be as easy as others' because I can see what an amateur job had been done by the ex-house owner. Leon's team turned out being professional, worked on my doors from morning to almost completely dark. They are typical craftsmen. After installation, thy cleaned the scene, even wrapped my long power cord. When they finished the installation, I saw a little damage on my sliding door's frame. As Leon said, he can fix everything. It turned out being true. He fixed it on scene. One week later, there is another issue coming out from my front door, Somehow the door's lock was hitting the frame. Leon showed up few days later, again proved me "he can fix everything" and explained to me it was caused by too much insulation he put. I am giving 9/10 because of this. So far my family are enjoying these two doors.
