Project Story
Therma-Tru French Door Conversion in Castro Valley, CA
AMG Doors & Windows converted this Castro Valley home's existing window opening into a new Therma-Tru French patio door system. The completed white double doors feature a 12-lite grid pattern, full-height glass, and direct access to the outdoor patio area.
1. Project Overview
The service, brand, and reason for replacement
AMG Doors & Windows converted this Castro Valley home's existing window opening into a new Therma-Tru French patio door system. The completed white double doors feature a 12-lite grid pattern, full-height glass, and direct access to the outdoor patio area.
2. Homeowner Pain Points
What the homeowner was dealing with
The original wall had a stationary window that offered a view of the backyard but no direct access to the patio. The homeowner wanted to open up the room, bring in more daylight, and add a functional door to the outdoor space without changing the overall footprint of the home.
3. AMG Solution

AMG Doors & Windows converted the existing window opening into a Therma-Tru French patio door system. The completed double doors are finished in white with a traditional 12-lite grid pattern and full-height glass on both slabs.

What AMG Doors & Windows installed
For this Castro Valley project, AMG converted the existing window opening into a Therma-Tru French patio door system with a 12-lite grid pattern, full-height glass, and a white exterior and interior finish.
4. Installation Details
How AMG installed this patio door
The installation involved removing the existing window, preparing the opening for a full-height double door, setting the Therma-Tru French patio doors, sealing the perimeter and threshold, and completing final swing, alignment, and hardware adjustment. Final exterior finish work such as stucco patching is scoped separately based on site conditions.
5. Final Result
The improvement for the homeowner
The completed Therma-Tru French patio doors give this Castro Valley home direct access to the patio, a brighter interior room, and a clean traditional 12-lite grid design on the exterior. The conversion preserves the original wall footprint while transforming the opening from a stationary window into a functional double-door entry.
Why we recommended this product:
Therma-Tru exterior doors are a strong fit for window-to-door conversions in Castro Valley. The French patio door configuration keeps the natural-light benefit of the original window while adding true door function, and the 12-lite grid pattern gives the opening a traditional look that coordinates with the home's exterior trim.

Frequently Asked
Questions about this project
Can an existing window be converted into a French patio door?+
Yes. In many homes an existing window opening can be reframed and expanded to receive a double French patio door system. AMG reviews the wall, header, exterior finish, and patio landing during the in-home consultation before recommending the right conversion approach.
What is a 12-lite grid pattern?+
A 12-lite grid pattern divides each door's glass panel into twelve rectangular sections using window grids. It gives French patio doors a traditional look while still allowing full-height glass and daylight into the room.
Why choose Therma-Tru for a French patio door conversion?+
Therma-Tru offers exterior door systems designed for durability, weather performance, and clean painted finishes. For this Castro Valley conversion, the Therma-Tru French patio doors provided the full-height glass, grid pattern, and white finish the homeowner wanted for the completed opening.
