Historic Window Replacement
We replicate historic windows with exacting detail using traditional joinery and modern materials. Our craftsmen match original lite patterns through true divided lites or simulated divided lites. All replacements meet St. Louis Cultural Resources standards while incorporating energy-efficient glass options for improved thermal performance.
Custom Wood Windows
Handcrafted from premium Ponderosa and Sugar Pine, our wood windows feature preservative treatments for extended durability. We also offer Sapele Mahogany options for enhanced resistance to weathering. Each unit is custom-built to match architectural specifications while maintaining historical accuracy in paint-grade or stain-grade finishes.
Curved Glass Windows
Our custom curved glass windows combine structural integrity with aesthetic precision. Using specialized bending techniques, we create radius and elliptical windows that maintain energy efficiency through insulated glass construction. These units integrate seamlessly with both historic and contemporary architectural styles.
Energy-Efficient Windows
We incorporate Low-E glass, tempered glass, and insulated panels into historic designs to meet modern energy standards. Our solutions maintain visual authenticity while reducing thermal transfer through advanced glazing technologies and weatherization techniques approved for historic properties.
True Divided Lites
Each true divided lite window features individual muntins crafted from solid wood for genuine historical accuracy. We replicate original patterns while ensuring structural integrity through reinforced joinery. This premium option preserves architectural integrity better than simulated alternatives while allowing customization for modern performance needs.
