6,000 windows. Four 37-story towers. Under seven months.
Owner-operated high-rise & multifamily window work across NY, NJ & CT — new construction and full replacement, engineered and delivered on time.
Trusted on landmark buildings across the tri-state area
In October 2025, Con Edison named AirGuard Windows its Multifamily Top Contractor of the Year for Window Replacement, and a Top Participating Contractor in its Multifamily Energy Efficiency Program — recognition from New York's largest utility for the energy-efficiency impact of our work on co-op, condo, and multifamily buildings.
AirGuard Windows is an owner-operated commercial window company handling both new construction and full replacement. We're not a manufacturer — we're the fenestration experts who engineer the right system, source it from the leading manufacturers, then supply, install, and manage the whole project. The same family that founded the company in 1984 still stands on site for every job, which is why co-op boards, condo associations, property managers, developers, and general contractors trust us with their most complex façades.
We do the work most contractors won't touch: ground-up new construction, occupied towers, oversized openings, historic conversions, and tight downtown logistics — delivered as a single accountable team from survey to closeout.
Real buildings. Real numbers. A portfolio few contractors in the country can match.

Before
After
Custom solutions for non-standard openings, oversized glass, enlarged heights, and historic conditions — engineered to perform and to pass inspection.
We're manufacturer-agnostic. We source and supply the right window and door systems for your building, budget, and code from the industry's leading manufacturers — not whatever one factory happens to sell.
From ground-up new construction to window replacement in fully occupied high-rises, our meticulous crews install with precision and minimal disruption — often returning residents the same day.
Surveys, scheduling, façade-consultant coordination, and closeout — a single point of accountability from first contact to final sign-off.
Our crew · on site
No middlemen, no mystery subcontractors. Our own experienced installers set every window by hand — here, a floor-to-ceiling unit going in dozens of stories above the East River, with residents back in their homes the same day.
The reasons boards and property managers keep our number on file for the next building.
Every project is owner-run. The decision-maker is on site — not a subcontractor three layers removed.
From ground-up high-rises and condos to full window-replacement programs, we handle both — start to finish.
We replace windows around residents and tenants. At Bella Vista, occupants were out of their units for just 5–7 hours.
We're not tied to one factory. We source the best window and door systems for your building, budget, and code from leading manufacturers.
Drip caps, enlarged openings, interlocking install sequences — we spec the system the building actually needs.
6,000 windows across four 37-story towers in under seven months. We plan the logistics so the calendar holds.
Quality has been the focus since 1984: the best materials and the most experienced crews, every time.
Licensed and active across New York, New Jersey, and Connecticut — from Manhattan high-rises to suburban campuses.
We assess the building, the openings, and the constraints — and listen to the board's priorities.
We design the system and deliver a clear, itemized proposal with realistic scheduling.
Product is sourced, manufactured, and staged to match the installation sequence.
Crews install unit by unit with minimal disruption, keeping the building secure and clean.
Final walkthrough, documentation, and a relationship that lasts past the last window.
