Intercoms for walk-ups, brownstones, co-ops and apartment buildings — tenants answer on their phone or an in-unit screen and buzz visitors in. New installs, retrofits on existing wiring, and repairs. NYS licensed (#12000287431).
If you own or manage a walk-up, brownstone, co-op or apartment building, the intercom is the one system every tenant uses every day — and the first thing they complain about when it stops working. We install, upgrade and repair apartment intercoms from 2-family homes to large multi-unit buildings.

Add fobs, PIN codes or phone unlock so tenants and deliveries get in without keys.
Electric strikes and maglocks so the intercom actually releases the door.

Most apartment intercom installations run $1,200 to $5,000+, depending mainly on the number of units, whether you keep the existing wiring, and whether tenants get in-unit monitors or answer on their phones. You get a written quote after a free site visit.
Often, yes. Many buildings can replace the front-door panel and reuse the wiring to each apartment, which keeps the cost down and avoids opening walls in occupied units.
Yes. App and cell-dialing intercoms ring tenants' phones, so they can see and talk to visitors and buzz them in from anywhere. Some buildings mix the two: phones for some tenants and in-unit monitors for others.
It depends on the system. Some cloud intercoms charge a yearly per-building or per-unit subscription; others have no recurring fee at all. We'll show you both side by side before you choose.
