Services
Commercial window installation
Our commercial window installation service delivers precision-fitted systems for new construction and replacement projects. Utilizing CAD technology and field-tested methodologies, we ensure seamless integration with building envelopes while maintaining structural integrity. The process includes detailed shop drawings, on-site dimensioning, and performance testing to meet energy efficiency standards for office buildings, educational facilities, and high-rise developments.
Historic window replacement
Specialized historic window replacement preserves architectural authenticity while modernizing performance characteristics. Our team replicates original designs using traditional craftsmanship techniques combined with contemporary materials to meet current building codes. This service includes leaded glass restoration, tax credit compliance documentation, and asbestos/lead abatement procedures for protected structures and heritage-listed buildings.
Curtain wall systems
We design and install unitized and stick-built curtain wall systems for commercial buildings requiring high-performance faades. Our solutions incorporate thermal breaks, water-resistant barriers, and seismic movement accommodations. The service includes engineering coordination, mock-up testing, and phased installation to minimize disruption during construction of office towers, medical centers, and institutional facilities.
Solar facade integration
Our building-integrated solar facade (BISF) systems combine photovoltaic technology with architectural glazing requirements. Partnering with Mitrex and ClearVue Technologies, we implement energy-generating faades that maintain aesthetic design intent while achieving LEED certification goals. This service includes energy modeling, structural load calculations, and grid connectivity planning for commercial and institutional buildings.
Window maintenance programs
We offer comprehensive window maintenance and retrocommissioning programs to extend system lifespan and maintain performance warranties. Services include seasonal inspections, sealant replacement, hardware recalibration, and emergency repair response. Our preventative maintenance contracts help property managers preserve asset value through documented service history and performance benchmarking for multi-tenant commercial properties.
