The thin black lines that define the look of a house.
Iron windows give a home the crisp black grid that people notice from the street: slim frames, narrow muntins and more glass than a typical vinyl or wood window of the same size. They are the finishing detail on modern farmhouses, European-style homes and contemporary builds across Texas.
Because each window is fabricated to its opening, iron windows can follow the design of the house instead of the other way around. Tall stair windows, wide picture windows, dormers and transoms above doors can all be built to match the same frame profile and grid, so the whole elevation reads as one design.
Pairing iron windows with iron entry and French doors from the same team keeps the finish, the proportions and the grid lines consistent across the house, which is hard to achieve when windows and doors come from different suppliers.

Fixed, operable and specialty shapes.
We build iron windows for every opening on the elevation, so the grid and finish stay consistent.
Fixed picture windows
Large fixed panes with a divided-lite grid for living rooms, stairwells and views.
Operable windows
Casement and other operable styles for ventilation, matched to the fixed windows around them.
Transoms & dormers
Windows above doors and in dormers built to the same profile as the rest of the house.
Tall & specialty shapes
Tall stair windows, arched tops and custom shapes fabricated to the exact opening.

Questions about iron windows.
What is the difference between iron windows and aluminum windows?
Iron windows have the classic divided-lite look with narrow black muntins, ideal for farmhouse, European and traditional styles. Aluminum windows use slim, thermally broken frames for large modern openings. Many of our projects use both.
Do you install iron windows in new construction?
Yes. We work with builders from the rough-opening stage and coordinate delivery and installation with the build schedule.
Can iron windows open?
Yes. We build fixed windows and operable styles such as casements, matched so the grid and frame look the same across the elevation.
Can you match my iron windows to my front door?
Yes. Because we build both, we match the finish, the frame profile and the grid pattern between windows and doors.
How much do iron windows cost?
Price depends on the size and number of windows, the grid, the glass and the installation. Send your plans or rough sizes for a free estimate.
