Window Restoration
Specialized restoration of pre-1910 double-hung windows preserves original materials while enhancing functionality. Our marine-grade repair techniques create durable joints that last decades, using traditional mortise-and-tenon joinery and waterproof wood treatments. Clients benefit from same-day window reinstallations that maintain home security throughout the process.
Door Replacement
Custom reproduction of Victorian and Edwardian front doors using solid heartwood ensures historical accuracy. Each door features traditional joinery techniques with slight handcrafted variations that maintain authenticity. Available in 20+ historic designs, these doors meet modern energy standards while matching original architectural details.
Weatherproofing
Targeted weatherstripping solutions prevent air infiltration while maintaining window operation. Our method seals gaps without compromising historic materials, using bronze weatherstrip and marine adhesives that expand window lifespan while reducing energy costs through improved climate control.
Noise Reduction
Historic window modifications improve sound insulation while preserving original aesthetics. By restoring proper window function and sealing gaps, we significantly reduce exterior noise transmission while maintaining period-accurate visual elements that complement historic architecture.
Custom Fabrication
On-site production of replacement wood parts ensures exact matches for historic windows. Our fabrication studio creates components that integrate seamlessly with original materials, using reclaimed heartwood and traditional joinery techniques to maintain structural integrity and historic authenticity.
