Window Replacement & Interior Trim

What changed

The original window and the exposed opening are the starting point for this project. The replacement was coordinated with work at the sill, interior returns and surrounding wall, so the visible improvement extends beyond the new unit alone.

The photographs show the opening during preparation, the replacement window with its installation labels and the interior after finishing. White trim frames the new unit against the retained wall color, bringing the installation back into the room.

• Removal of the original window assembly.
• Preparation of the exposed interior opening.
• Work around the sill and interior perimeter.
• A new white-framed replacement window.
• Renewed interior trim and surrounding wall finish.
• A final interior view connecting the window to the existing room.

The work, step by step

Stage 01

The original window

The starting photograph shows the existing window set within a deep interior opening. The unit, sill and surrounding trim establish the original appearance of this part of the room before the replacement work began.

This view provides the comparison with the finished installation: the window remains in the same wall opening, with the new unit and renewed interior edges brought back into the room.

Stage 02

Opening the window area

The original window assembly was opened up for the replacement. The photograph shows the exposed perimeter, existing timber and the wall edges around the opening after the visible unit was removed.

With these areas accessible, the work could address the interior opening as well as the replacement window. The lower wall edge and the side returns are visible at this stage, before the finished trim is reinstated.

Stage 03

Preparing the sill & surrounding wall edges

The next views show preparation around the inside of the window opening. The sill area and perimeter edges are brought together with new wall-board sections around the exposed work, creating the transition between the retained wall and the installation.

These details matter to the appearance of the finished opening: the window, sill, side returns and wall surface need to meet cleanly. The photographs record this part of the work before the finished replacement unit and its interior trim are fully in view.

Stage 04

Installing the replacement window

The replacement window is shown fitted into the opening, with product labels still on the glass. Its white frame and horizontal meeting rail establish the new appearance, while the surrounding interior surfaces continue through the finishing stage.

This view connects the exposed opening with the final result. It shows the new unit in place before the labels are removed and the room is presented as a completed installation.

Stage 05

Interior trim & the finished room

The final views show the replacement window with its labels removed and the surrounding interior finish reinstated. White casing and sill details frame the unit against the painted wall, bringing the opening back into the room.

The closer photograph shows the window itself; the wider view shows how the trim and repaired wall area connect with the existing baseboard and floor. Together they complete the visible sequence from the original unit to the finished interior.
