At Whole Window, we specialize in professional repair of wooden window sashes across the Greater Boston area. Our mission is to restore historic wood windows with precision, preserving the charm and energy efficiency of your home.

What Is a Window Sash?

A sash is the movable part of your window that holds the glass and fits into the frame. Over time, wooden sashes can suffer from rot, warping, cracked glazing, and stuck movement — but that doesn't mean you need full window replacement.

Our Wooden Window Repair Process

1. Detailed Inspection
   We start with an on-site assessment to evaluate the sash, rails, joints, and glass.

2. Safe Removal
   If needed, the sash is carefully removed to allow for comprehensive wooden window repair.

3. Rot Repair & Restoration
   Damaged wood is removed and replaced using high-quality materials. For minor decay, we apply professional wood sash epoxy restoration techniques.

4. Glass Reglazing
   We reglaze or replace glass with care, using period-appropriate materials. This is key in restoring old wooden windows to their former glory.

5. Priming & Weatherproofing
   All surfaces are sealed and painted with weather-resistant coatings to extend the life of your windows.

6. Reinstallation
   We reinstall the sash and ensure proper fit, smooth operation, and full energy-efficient sealing.
