Replacement Window Insert Units

There are several strategies and products to replace older windows without having to remove any trim, siding or drywall.

Several window manufacturers make complete double-hung replacement window units that come without exterior trim and that are engineered to fit INSIDE the jambs of an old double-hung window. They are custom built to fit exactly into the existing opening. The result is more energy efficient, more functional, and, usually, more attractive.

Then you insert the unit and secure it to the existing jambs. They generally have trim pieces that will cover the gap between the new unit and the trim.


Replacement Sash Kits

Once the old window and stops are removed you fasten metal brackets evenly down the window frame and snap the vinyl jamb liners in place.
