We manufacture Advanced Energy Panels (AEPs). AEPs are a retrofit for historic windows or any window people can't afford or don’t wish to replace. AEPs are interior window insulating panels and can be installed in any building –office, home or industrial. AEPs have a higher insulation and air sealing rating and provide greater comfort than most replacement windows, yet they are a fraction of the cost. AEPs are custom made to fit over existing openings, protecting, preserving and improving your existing windows.

Egress Windows questions, answered by experts

The proper way to install a window well is to measure the window, dig a hole deeper and wider than the window, place a drainage tube and cap, anchor the well to the foundation, caulk the seam, and backfill the hole. The job requires tools such as a hammer drill and auger and some heavy digging. Proper placement and window well installation are critical to preventing water from leaking into the window.

Finding a reputable contractor for any type of work on your home is best done by conducting research into local professionals. Here are some tips for finding a good contractor:

  • Search for local egress window installation contractors near you

  • Read customer reviews

  • Check out the contractor’s website

  • Look at the portfolio of work completed

  • Call and ask about the contractor’s experience installing egress windows

  • Check to see if the contractor is licensed

Options include double-hung, casement, and sliding windows. Materials include wood, vinyl, and aluminum.

New window installation costs range from $300 to $1,500 per window, depending on size, material, and energy efficiency features.

Adding windows to a house is expensive. Budget roughly $5,800 to add a single window, and double or triple that to add two or three. In some cases, adding a single window can exceed $20,000, depending on the type of exterior wall, the size of the window, the type of window, local permit costs, and other factors.
