Our Window Replacement Process

  1. We offer a free, in-home consultation and a no obligation estimate. This estimate includes inspecting the area for rot or damaged concrete prior to installation, along with the removal and disposal of existing material.
  2. Our consultants help you select from a variety of windows styles and paint choices.
  3. After taking measurements and finalizing the order, it takes about 4-6 weeks for your windows to arrive. We will contact you to confirm the installation date.
  4. As well as installing your new windows, we properly insulate and trim the outside perimeter of the windows, and ensure that all interior trim is done to your specifications.
  5. We clean up the area when we are done.
