What Our Customers Are Saying

  • "Guaranteed Aluminum installed 24 thermal windows at our home in Lowell in two days. We were impressed by their professionalism and quality of their work. They went to great lengths to make sure everything matched and that we were happy with our choice of outside color for the trim. We recommend Guaranteed Aluminum for anyone in the market for windows and siding."

    Dan & Marie T.

  • "They did a great job fixing an old screen for me and making a new screen for one window that was missing a screen. The new screen fit perfectly and worked beautifully. The work was done quickly too (within 3 days) and at a reasonable price. I will definitely use Guaranteed Aluminum again when I need screens repaired or replacement windows."

    Dawn M.
