Window Sash Repair and Replacement in Chicagoland

The sash is the movable frame that holds the glass. When it sticks, rots, or breaks, you do not always need a new window. We repair and replace sashes for homes in Des Plaines and the Chicagoland area. Estimates are free.

Free estimates. Project suitability is confirmed during your estimate.

Signs a sash needs attention

  • A sash that sticks or is hard to open and close
  • A loose or rattling sash
  • Rotted, cracked, or separated corners and joints
  • Broken glass or failing glazing in the sash
  • A sash that will not stay up on its own

What the work can include

  • Repair of damaged sash corners and joints
  • Replacement of rotted wood sections
  • Glass replacement in the sash
  • Balance and hardware repair so the sash moves and stays put
  • Sash replacement where a sash cannot be repaired
  • Full window replacement when repair is not the right fit

Repair or replace?

When is a sash repaired, and when is it replaced?

Small areas of damaged wood can often be repaired. A badly rotted or broken sash may need to be replaced. In some cases the whole window is the better choice.

We check the sash and the frame together, then explain what we recommend. Project suitability is confirmed during your estimate.
