After meeting Mohammed, a sales person for Quality First Home Improvement, living with drafty windows shouldn't be an option! The benefits definitely out weighed any concerns I had.... "and he is quite the educator!" Mike Ross, their PC, sent two very skilled workers, and in less than an hour and a half they installed a very large, six foot triple pane window in my front room! "I was impressed with how fast they worked, and did a very professional job!"
