Custom Signs in Southwest Washington — Fabricated in Tacoma Since 1986

Yes. Plumb Signs is headquartered at 909 S 28th Street, Tacoma, WA 98409, and our daily service area runs south through Lacey, Tumwater, Shelton, Centralia, Chehalis, and Vancouver. Mason Health Shelton, Public Storage Lacey, and the Vancouver SE 6th Street illuminated cabinet program were all designed, fabricated, and installed by our Tacoma shop.

A push-through letter monument is a routed aluminum-faced cabinet with translucent acrylic letters pushed through from behind and back-illuminated by LEDs. It produces crisp, evenly-lit letterforms during the day and at night, and it is the technique used at the Mason Health Shelton main entrance monument — the recommended approach for healthcare and corporate monument programs that need readability from a parking-lot approach.

Recent SW Washington work includes the Mason Health Shelton campus monument and wayfinding program, the Public Storage building identification in Lacey, an illuminated wall cabinet program on SE 6th Street in Vancouver, and the Timberland Bank multi-location brand rollout that includes the Olympia headquarters and branches in Lacey and Tumwater. Each project has a live case study on the site.

Day/night vinyl is a translucent two-layer film engineered to read as the brand color in daylight and as bright white at night when the cabinet or channel letter is back-illuminated. Standard translucent vinyl reads roughly the same color day and night, which limits nighttime contrast. Day/night vinyl is the standard on the Mason Health Shelton cabinets and on healthcare and corporate programs where nighttime legibility matters.

Commercial signs in Vancouver, Lacey, and Shelton typically require a sign permit through the local planning or building department, engineered structural drawings for monument and pylon signs, and electrical permitting for any illuminated cabinet or channel letter. Plumb Signs prepares the permit package, submits it, and follows it through to approval — we pull commercial sign permits across all three jurisdictions, plus Tumwater, Centralia, and Chehalis.

Marine-grade aluminum is a corrosion-resistant alloy specification — typically 5052 or 5086 — chosen for its ability to hold up in wet, salt-influenced Pacific Northwest exposure. Sign cabinets fabricated in marine-grade aluminum resist pitting, oxidation, and edge corrosion long-term, which is why we spec it on coastal and high-exposure projects like the Mason Health Shelton cabinets.

UL-listed means the illuminated sign has been built to Underwriters Laboratories safety standards for electrical signage — wiring, LED drivers, grounding, and enclosure construction all meet the listed specification. UL-listed signs pass electrical inspection more reliably and carry lower long-term liability for the building owner. Every illuminated sign Plumb Signs builds is UL-listed, including the Vancouver SE 6th Street cabinet program.

Our installation and service crews dispatch from Tacoma across the full SW Washington corridor — Mason, Thurston, Lewis, Cowlitz, Grays Harbor, and Clark counties — and we have installed and serviced signage from Shelton to Vancouver on the same week. For multi-site rollouts like the Timberland Bank program, we coordinate phased installation across all sites from a single Tacoma-based project manager.
