Based in Lynnwood, working across western Washington: a free site walk, a firm written price, a 30-day free trial, then month to month.
Building in Bellevue
Bellevue's job sites are mostly vertical: tower cranes downtown, mixed-use blocks in the Spring District and along the Bel-Red corridor, and build-outs near the light rail stations. Tower sites keep their gear on a tight footprint, so the cameras watch the gate, the laydown area, the ground floor, and the hoist.
On the wider Eastside sites, where a fence line wraps a whole block, a camera vehicle stationed on the property adds a deterrent anyone can see from the street, watched live by our team through the night.

Do you cover high-rise builds in downtown Bellevue?
Yes. On a tower build we watch the gate, the laydown area, the ground floor, and the hoist after hours, and the written site plan is updated as the building goes up.
Will my crews or deliveries set off alerts?
No. At setup we record your working hours, who's allowed on site after hours, and expected deliveries, so a crew member or a delivery is never treated like a break-in.
