Our restoration service meticulously repairs and revives damaged stained glass windows using hand-painted replication and vintage glass inventory. We replace lead came with custom-manufactured materials to preserve structural integrity.

Custom Window Design
We create custom stained glass windows tailored to architectural styles and client visions. From initial design consultations to final installation, our artisans ensure seamless integration with existing decor. Clients receive scale renderings and collaborate on color and texture choices for personalized, lasting art pieces.
Storm Glazing Installation
Our storm glazing service installs tempered or non-tempered glass to protect stained windows from weather and vandalism. We use low-profile aluminum frames matched to exterior colors, ensuring thermal efficiency and light transmission without compromising aesthetics or durability.

We design light boxes for repurposed stained glass windows using hardwood frames and diffused fluorescent lighting. This service allows churches and institutions to showcase gifted windows in non-traditional spaces while maintaining visibility and artistic integrity.
