Our Services

Our building envelope restoration services address every component of your building's exterior shell. From historic terra cotta façades to modern curtainwall systems, we diagnose issues at their source and implement lasting solutions. Our work includes brick repointing, stone replacement, through-wall flashing, sealant replacement, and comprehensive waterproofing — all performed to exceed industry standards and NYC building code requirements.

Citiline delivers comprehensive roofing and waterproofing solutions for commercial and residential properties. We specialize in all major roofing systems including modified bitumen, EPDM, TPO, and built-up roofing. Our waterproofing expertise extends below grade, protecting foundations, parking structures, and plaza decks from water infiltration. Every system we install is backed by manufacturer warranties and our own workmanship guarantee.

Structural integrity is the foundation of every safe building. Our structural repair division handles everything from concrete spalling and steel corrosion to full balcony reconstruction and parking garage rehabilitation. We work with licensed engineers to assess, design, and execute structural repairs that restore and often exceed original load-bearing specifications. All work complies with NYC DOB requirements and ACI standards.

New York's landmark buildings require a specialized touch. Our landmark preservation team has extensive experience working with the Landmarks Preservation Commission (LPC) to restore protected buildings to their original grandeur. From historic terra cotta and limestone restoration to ornamental ironwork and cast stone fabrication, we use period-accurate materials and techniques to honor each building's architectural heritage.

Navigating New York City's complex building codes requires specialized expertise. Citiline manages the full lifecycle of Local Law compliance — from initial inspection and engineering assessment through DOB filing, repair execution, and sign-off. We handle FISP (Local Law 11) inspections, Local Law 126 requirements, and work closely with QEWIs and building engineers to ensure timely compliance and violation removal.
