Custom Design & Installation from Berry Door & Window
Every home features unique architectural details, and a generic, mass-produced door package rarely does a space justice. That is why we handcraft every door with a transom to match your exact taste and performance requirements.
Completely Tailored to Your Style
We offer complete customization for your new transom assembly. You can select from clear glass to flood your foyer with maximum sunshine, decorative textured glass for extra privacy, or intricate leaded designs that match historic detailing. From frame finishes and stain colors to custom grille patterns and hardware, every element is chosen by you to complement your home’s exterior.
Rectangular, Arched, & Radius Shapes
Whether your home calls for a clean, modern rectangular transom or a classic, sweeping arched radius shape, we engineer the glass and frame to fit the exact contours of your entry. Our craftsmen build complex geometric designs in-house, ensuring smooth lines, tight seals, and flawless proportions.
Expert In-House Installation
A beautiful transom requires specialized installation to prevent air leaks, water intrusion, or structural sagging over time. We never hand off your installation to third-party subcontractors. Trained Berry employees manage your installation from start to finish, treating your property with respect and ensuring a snug, weatherproof fit.
Key Benefits of Custom Transom Doors
Upgrading your entrance with a custom transom door offers several practical and aesthetic advantages:
1
Abundant Natural Sunlight
Bring bright daylight into dark hallways and foyers without giving up privacy or sacrificing valuable interior wall space.
2
Added Height & Visual Grandeur
Drawing the eye upward, a transom makes standard-height ceilings look higher and gives standard entryways an impressive, estate-like feel.
3
Architectural Character
Transoms add timeless charm that suits traditional brick homes, historic townhouses, and sleek modern designs alike.
4
Versatile Entry Combinations
A transom pairs seamlessly with a single entry door, expansive double entry doors, or a full system featuring our signature hinged sidelite doors.
5
Midwest Weather Protection
Built with high-performance, energy-efficient glass packages, our transoms are engineered to seal tight against humid St. Louis summers and freezing winter winds.

Frequently Asked Questions
A transom door features a glass window panel installed directly above the main door frame. Our transoms are built as fixed units (which do not open and focus purely on letting in light).
Yes. Because a transom is installed vertically above the door rather than horizontally along the sides, it adds light and height without requiring you to widen your entryway. Our design team measures your space to determine how much vertical room is available for a custom transom frame.
