I spent $12,000 for a permanent draft I got 11 replacement windows in the whole downstairs in my home I was assured that this would cut my energy cost however I'm cranking my heat up and feeling colde

Awful experience. Waited months and day of install 3 of the 16 windows arrived cracked /broken glass . I made it clear I wouldn't pay for broken windows. Installers agreed and had me sign with my cred
