We had an all around excellent experience with St Clair Windows and Doors. They installed a four panel 10 foot sliding door and three casements. I'm sitting here enjoying the breeze with them all open! So glad I had them do the work. They paid close attention to detail and did a great job protecting my new floor while doing the work. They went the extra mile on the brick work after cutting in for the new slider. Great crew working for St Clair. Everyone was polite, respectful and neat and tidy all through the installation and cleanup afterwards. Thanks for a great experience.
