Most vendors treat windows and doors as a line item. We treat them as a discipline.
Fenhaus works exclusively with architects and custom builders in Western Pennsylvania who expect precision, accountability, and technical depth from the people responsible for their most visible building systems.

As Featured in
A window is not simply an opening in a wall. It is a decision about how light enters a room, how a landscape is revealed, where the interior life of a home meets the world outside. Fenhaus exists to protect that decision, from the architect's first sketch through the final installation. Beauty has a specification. Fenhaus knows it.
We engage during design, not after drawings are finalized and pricing is fixed.
We specify the right system and deliver clear, timely quotes.
Direct answers on glazing, thermal performance, rough openings, and lead times.
Visit our Pittsburgh showroom to see full scale systems in person before you specify them.
Documentation, site support, and direct manufacturer access when needed.
