Lee, the owner Security Glass Block, arrived on time for the estimate appointment. He explained what would be done to replace existing windows with glass block, and showed examples. Installer then arrived on time, and removed old windows and frames in basement and garage, installed new glass block windows with air vents and put masonry around windows and cleaned up. I couldn't be happier with the entire experience, and the price!
I know it will have to save me on energy costs, and keep us safe from intruders, because my basement windows were in such bad shape.
