Choosing between a retrofit (insert) and full-frame window installation depends on your building’s condition, energy goals, and budget.
Retrofit Window Installation
Inserts are installed into the existing frame without removing trim or flashing.
Best For:
Homes with solid, undamaged frames
Faster, more cost-effective upgrades
Minimal disruption to siding and interiors
Limitations:
May not fully resolve insulation or leakage issues
Won’t allow for new flashing or moisture barrier updates
Full-Frame Window Installation
Removes the entire existing window, including frame, and replaces it with a new unit.
Best For:
Older homes with signs of rot, mold, or air leakage
Major renovations or energy retrofits
Net-zero or Step Code–compliant construction
Benefits:
Better air and water sealing
Opportunity to insulate around the frame
New flashing and integration with WRBs
