Many of Cresskill’s large houses went up between the mid-1990s and the mid-2010s, and still run the systems they were built with.
In short
Cave Group upgrades, takes over, and services Crestron and Lutron systems in Cresskill, New Jersey, and designs new lighting control, audio-video, networking, and security for houses being built or renovated. Crestron Elite Gold Partner and Lutron Gold Dealer with an office in Fairview, Bergen County.
Cresskill, Specifically
Twenty-Year-Old Systems, Due for Renewal.
State records show that the Cresskill homes sold at the top of the market between 2022 and 2024 sit on lots of roughly one to two acres and were built between 1996 and 2014. A control system installed in those years was designed before the smartphone was common, and its manufacturer has often stopped making parts for it.
That makes Cresskill a town of upgrades: houses with good wiring, good speakers, and a processor that is living on borrowed time.
01 · Survey
Find Out What You Have
We start by identifying every processor, panel, and amplifier and checking which are still supported. You get a list in three columns: keep, upgrade, replace.
02 · Upgrade
New Processor, Same Wiring
In most houses the keypads, the speakers, and the cabling stay. The processors and interfaces are replaced and the programming is rewritten, with the walls closed.
03 · Support
Someone Watching It
Once the system is current, we monitor it remotely and fix most faults before anyone is home to notice them.

Cresskill, Answered
Who upgrades older Crestron and Lutron systems in Cresskill, NJ?+–
Cave Group does. We are a Crestron Elite Gold Partner and Lutron Gold Dealer with an office in Fairview, in the same county. We take over systems other companies installed, bring them up to current hardware on the existing wiring, and support them afterwards.
How do we know whether our system is at the end of its life?+–
The usual signs are touchscreens that freeze, an app that no longer updates, keypads that respond late, or an installer who cannot get parts. We can identify the processor generation from the equipment rack and tell you where it stands with the manufacturer.
Does an upgrade mean living in a construction site?+–
No. Most of the work happens at the equipment rack. We plan it so that the house is never without lights, and most rooms are back in service the same day. The walls stay closed.
The original installer is out of business. Can you get into the system?+–
Usually. If the programming files were left with the house, we start from those. If not, we document what the system does and rebuild the programming, which is often an improvement on what was there.
Do you also handle new construction in Cresskill?+–
Yes. For a new house we join the architect and builder at the drawing stage and carry the project through commissioning and support.
