We Solve Problems
When Things Stop Working
Most service calls start the same way: something stopped working and nobody knows why. We are most useful when the work order is poorly defined and the actual cause has to be identified on site — often across system boundaries — before the correct repair, part or trade can be determined.
LED & Accent Lighting Failure
LED strips, tape, modules, drivers, power supplies and dimming controls.
AV, TV & Signage Problems
Displays, digital signage, audio distribution and signal routing.
Network, Wi-Fi & Internet Issues
Access points, switches, connectivity and devices dropping offline.
IP Camera & CCTV Problems
Cameras offline, NVR recording faults and video system connectivity.
Automation & Smart System Faults
Controllers, gateways, sensors and devices that stopped communicating.
Motorized Shades Not Responding
Shade controllers, power supplies, motors and communication faults.

What We Do
Technical Support Services
Troubleshooting first. We are called when something has already stopped working — a technical system, a fixture or a piece of equipment — and we take the commercial facility service call from diagnosis through to the report.
On-Site Diagnostics
We test the actual system on site and identify what failed — not a guess over the phone.
Root Cause Analysis
Failures cross system boundaries. A display problem is often a network problem.
System Recovery
We restore operation within scope and verify it before leaving the site.
Service Documentation
Photo documentation, technical findings and a clear service report for every call.
