Assess: Sash Replacement
If your window frames are in good shape, you can save money and boost efficiency by replacing only the sashes – the part of the window that holds the glass in place and opens and closes. Window frames do not need replacing as long as air leakage is minimal, the frames and the walls around them do not show significant wear and tear, and if there is no damage from water, mold or mildew. An energy auditor or contractor may help you determine if a sash replacement is a viable option. Many manufacturers offer replacement sash kits that ensure operability and fit.
