Not every window problem calls for a full replacement. Kenemax operates a dedicated service department that handles repairs across residential and commercial buildings throughout New York City — from a single malfunctioning sash to a building-wide caulking program.
We survey, scope, and repair. Our crews service existing windows rather than replace them wherever the window can be brought back to proper function. When replacement is the right answer, we'll tell you that too — and handle it the same way.
We assess each window, document conditions, and scope the work — giving you a clear picture of what needs attention and why.
A detailed scope with itemized pricing — organized by repair type and unit so you can plan and budget accordingly.
Our crews work efficiently within occupied buildings — coordinating with building management to minimize disruption to residents.
Repair labor is covered for 6 months. Parts and materials are covered for 1 year. If something isn't right within that period, we come back and make it right.
A full operational check on each window — lubricating balances, locks, and hardware to restore smooth function. Often the most overlooked and most effective service a building can schedule.
Replacement of bottom sash balances, shoes, and pivot pins. When windows won't stay up or feel heavy to operate, worn balances are typically the cause. Replaced in sets of two per window.
Installation of sash channel bump-stop limiters restricting window opening to 4 inches. Required by NYC law in apartments where children 10 and under reside. Installed in sets of two per window.
Replacement of window locks and latches that are broken, stripped, or no longer securing properly. Replaced in matching sets to maintain consistent hardware across the unit.
Reglazing with a new IGU (insulated glass unit) within the existing sash. Addresses fogging, seal failures, and broken glass — without replacing the entire window or frame.
Replacement of a full sash — including new balances, shoes, and pins — within the existing frame. When the sash itself is damaged beyond repair but the frame is still sound.
When the full unit needs to go — frame, sash, and all — we handle the complete removal and replacement including new anchor clips. The right call when repairs are no longer cost-effective.
Application of exterior perimeter caulking on existing windows. Seals air and water infiltration at the window-to-wall interface — one of the most effective weatherproofing measures for aging building envelopes.
Replacement of interior perimeter aluminum trim that is bent, damaged, or missing — restoring a clean finish around the window opening without a full unit replacement.
Re-meshing of existing window screens with torn or deteriorated mesh. The existing frame is retained and re-screened — a straightforward repair that restores function without full screen replacement.
Supply and installation of complete new window screens with frames, custom-fitted to each opening. Supplied and installed when the existing frame is damaged or no longer usable.
We'll come out, survey the conditions, and tell you exactly what's going on — no commitment required. Many buildings schedule an annual service visit as standard practice.
Schedule a SurveyOur service department works closely with property management companies, co-op and condo boards, and building owners who need a reliable contractor they can call year after year. We understand building operations — we work around residents, coordinate with supers, and document everything.
Repair labor is covered for 6 months from the service date. Parts and materials carry a 1-year warranty. If a repair fails within those terms, we return at no cost.
When the scope of work requires permits or filings, we handle the paperwork. We coordinate with building management so nothing falls through the cracks.
Our proposals are broken down by repair type and unit — giving building managers the documentation they need for board approvals, reserve studies, and capital planning.
We schedule unit access with residents, work efficiently, and leave each space clean. Most individual window repairs are completed within a single visit.
Contact us to schedule a survey or discuss your building's service needs. We'll assess the conditions, scope the work, and provide a clear proposal — no obligation, no guesswork.
