Door & Window Installation & Repair in New York

Leon and Son LLC provides door and window installation and repair in New York. Sticking doors, failed hinges, broken locks, drafty sashes, and weather sealing in Manhattan and Brooklyn buildings.

The Service

Most Door Problems Are Alignment Problems

A sticking door in a New York building is rarely about the door. The frame moved, a hinge loosened, or the floor settled. Planing the edge hides that for a season and then it sticks again.

The same logic applies to windows. Sashes that will not close, locks that will not catch, and January drafts usually trace back to alignment and sealing. Rarely to the glass itself.

What's Included

What Doors & Windows Includes in New York

Interior Door Installation in New York

Unit doors, closet doors, and bathroom doors hung square in buildings that are rarely square themselves. Interior door installation in New York means shimming the frame properly instead of forcing the slab to fit. Square doors close and stay closed.

Exterior Door Installation in New York

Entry doors, service doors, and building access doors installed with proper alignment, secure hardware, and full weather sealing. Building entries in Manhattan and Brooklyn take constant use, so the hardware matters more. Entry hardware always fails first in busy buildings.

Door Repair and Alignment in New York

Sticking doors, dropped hinges, doors that will not latch, and frames that shifted with the building. Each one gets adjusted, rehung, or replaced, depending on what the actual problem turns out to be. Planing the slab alone only hides it.

Window Repair in New York

Sashes that stick or will not stay up, failed balances, broken locks, and drafty frames in older New York units. Repair comes first, and full replacement only when repair genuinely stops making sense. Co-op buildings usually require board approval first.

Lock and Hardware Replacement in New York

Locks, deadbolts, closers, handles, hinges, and strike plates replaced and aligned correctly. Building security in New York fails at the hardware long before the door itself. That gets checked first on every single visit. Alignment fails before the lock does.

Weather Sealing in New York

Weatherstripping, sweeps, caulking, and gaps sealed before the heating season starts. A drafty door in a New York winter costs money every day and generates tenant complaints that nobody enjoys fielding. Drafts cost money every single day all winter long.

FAQs

Doors & Windows Questions

Usually humidity, heat, and a frame that moved. Steam heat swells wood, and older New York buildings settle. Planing the door alone hides it for a season, so the frame gets checked first.

Both, but repair comes first when it makes sense. Balances, locks, and sealing fix most complaints. Full window replacement in landmark or co-op buildings usually needs board or agency approval first. Every time.

Yes. Entry doors, service doors, and building access doors, with proper alignment, secure hardware, and full weather sealing. Building entries take constant use, so the hardware gets specified accordingly. Specified for real use.

Yes. Locks, deadbolts, closers, handles, and strike plates. Most security problems in New York buildings are alignment and hardware, not the door. That gets checked first. Hardware is where building security usually fails.

Most adjustments are the same visit. Rehanging a door or replacing a frame takes longer. Replacement doors need ordering time, which the estimate accounts for. Nothing in the schedule gets promised without ordering.
