Services
The last public Sign King site was built around three sign products — channel letters, lighted boxes, and interior work. The shop also contracts electrical, HVAC, sheet metal, welding, and painting for commercial, federal, and GovGuam work.
Signage
LED-lit channel letter signs that make a storefront stand out from the crowd — fabricated in Guam.
Dimensional letter faces, returns, and raceways built in our Harmon shop. The 2020 Sign King site put this first for a reason: nothing reads a business name at night like a properly lit channel letter.
Signage
All-aluminum cabinets with even lighting — a durable, cost-effective face for the street.
If the budget is tight, a lighted box is the workhorse. Aluminum construction for island weather, bright even lighting so the copy carries from the road.
Signage
A complete interior sign solution — wall wraps, display panels, and custom identity work.
From wall wrap to a custom display panel, we fabricate interior decoration and promotion pieces to match the job. Lobby letters, directories, and tenant ID.
Electrical
Trade
Sign circuits, lighting, and licensed electrical work that keeps a project powered and inspectable.
Channel letters and cabinets are only half the job. We handle the electrical that feeds them, plus broader licensed electrical contracting on Guam commercial and federal work.
HVAC
Trade
Heating, ventilation, and air-conditioning work for shops, offices, and government facilities.
Island buildings live and die by cooling. Sign King provides HVAC contracting alongside the metal and electrical trades already in the shop.
Sheet metal & welding
Trade
Shop-fabricated sheet metal, weldments, and custom steel or aluminum for signs and building work.
The sign shop is a metal shop. Cabinets, raceways, brackets, frames, and field weldments come out of the same Harmon floor that builds the letters.
Painting
Trade
Industrial and architectural painting for signs, metal, and building surfaces.
Faces, returns, poles, and building fascia — painted in the shop or on site so the finished sign and the wall behind it read as one job.
