The Problem

  • The opening was tall and narrow, making the internal grille proportions a visible part of the exterior design.
  • The window frame was still usable, so removing the complete assembly would have added work without addressing a frame failure.

How We Fixed It

  • We removed the old sealed unit, prepared the existing sash pocket and installed a new insulated glass unit with an internal decorative grille.
  • The panel was set and sealed within the original frame.

The opening regained a clear insulated panel and a grille pattern that fits the existing residential design.

Frequently Asked Questions

Can the glass be replaced without replacing the full window?

Often yes. If the frame and sash remain serviceable, the insulated glass unit can be measured and replaced separately.

Can an internal decorative grille be included in new window glass?

Yes. The grille pattern can be built inside the new sealed glass unit when its layout and proportions are specified.

Is Bolton part of the Caledon service area?

Yes. This project was completed in Bolton and is linked to our Caledon service area.
