Insert Replacement Windows

Insert Replacement Windows in Grand Rapids

When your existing frame is still sound and square, an insert replacement is the faster, less invasive path to new windows. Fishtommy fits a new unit into the existing frame, keeping your interior and exterior trim intact while upgrading the glass and sash. It is a popular choice for the mid-century and newer homes out toward Kentwood and Cutlerville, where original frames often have plenty of life left in them.

Why Choose Insert Replacement

• Keep your trim. The existing casing stays put, so there is no plaster or siding repair on a 49508 home.
• Faster install. Less demolition means many openings are finished the same day.
• Real efficiency gains. New double-pane low-E glass with argon fill cuts drafts and lowers heating bills.

Our Process

We confirm the existing frame is square, sound, and free of rot, then measure for a precise fit. We set the insert unit into the frame, seal it against air leakage, and adjust the sash so it opens and locks smoothly. Because the trim stays intact, cleanup is quick and your rooms are back to normal fast. We match the low-E glass and U-factor to your comfort goals.
