Recent Tacoma Projects

Four projects we designed, fabricated, and installed in Tacoma — each with its own live case study.

One Tacoma Shop. Every Stage of the Sign.

Most signage projects in the South Sound get handed off between three or four vendors — a designer, a fabricator, a permit runner, an installer. Plumb Signs handles all of it from one shop on S. 28th Street. That means one accountable team for the schedule, one set of drawings that match what gets built, and one phone number when something needs service ten years later.

We are a UL-listed fabricator and a licensed Washington contractor. Every illuminated sign we build uses Class 2 low-voltage LED drivers with rear service access, marine-grade aluminum cabinets engineered for Pacific Northwest exposure, and the named construction techniques a facilities director or general contractor needs to spec a sign correctly: push-through letter monuments, raceway-mounted channel letters, halo-lit reception signs, and single-face aluminum monuments.

What We Build for Tacoma Businesses

Monument Signs

Single-face aluminum monuments anchored on concrete footings, plus push-through letter monument cabinets with translucent acrylic letters and rear LED illumination. Permitted, engineered, and installed to Tacoma Planning Department requirements.

Channel Letters & Cabinets

Raceway-mounted and flush-mount channel letters in aluminum with translucent vinyl faces — including day/night vinyl that reads color in daylight and white at night. UL-listed cabinets with Class 2 LED drivers and rear service access.

Pylon & Pole Signs

Engineered pylon signs for high-visibility corridors, including the kind of structural pylons installed at Cheney Stadium. Steel pole design, foundation engineering, and electrical hookup all coordinated in-house.

Wayfinding & ADA Interior

Campus and facility wayfinding systems — the same work we did for UW Tacoma and MultiCare Allenmore. ADA-tactile suite identification with raised characters and Grade 2 Braille on non-glare finishes.

LED Displays & Scoreboards

Electronic message centers, ribbon displays, and full LED scoreboard programs — including the stadium-wide upgrade at Cheney Stadium for the Tacoma Rainiers in 2025.

Service, Repair & Maintenance

Same-day dispatch from Tacoma for LED driver replacement, face repair, electrical troubleshooting, and storm damage. We service signs across Pierce, Kitsap, King, Thurston, and Mason counties.

Why Tacoma Buyers Choose Plumb Signs

  • 40 years in Tacoma, since 1986. Same shop, same address — 909 S 28th Street — through four decades of South Sound commercial growth.
  • UL-listed fabricator. Every illuminated sign we build is UL-listed. Class 2 low-voltage LED drivers, rear service access, and electrical work that passes inspection the first time.
  • Licensed & insured Washington contractor. Bonded for commercial work statewide. Our installation crews are certified for the structural anchoring and electrical hookup that large monument and channel-letter programs require.
  • Deep Tacoma Planning relationships. We pull commercial sign permits in Tacoma weekly. We know the submittal requirements, the typical comments, and the path to approval — fewer surprises, faster sign-off.
  • One shop, every stage. Design, fabrication, permitting, installation, and service all under one roof. No vendor handoffs, no missing context between stages, no finger-pointing when something needs follow-up.

Tacoma Signage — Frequently Asked Questions

Where is Plumb Signs located?

Plumb Signs is headquartered at 909 S 28th Street, Tacoma, WA 98409. The design studio, fabrication shop, and installation dispatch all operate from the same location.

How long has Plumb Signs been making signs in Tacoma?

Since 1986 — 40 years of continuous operation at the same Tacoma address. We have been a UL-listed fabricator and licensed Washington contractor through that entire history.

What permits does a commercial sign need in Tacoma?

Commercial signs in Tacoma typically require a sign permit submitted to the Tacoma Planning Department, with 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.

What is a push-through letter monument?

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 we recommend for healthcare and corporate monument programs that need readability from a parking-lot approach.

What is a raceway-mounted channel letter?

A raceway-mounted channel letter is a building-mounted aluminum letter housed on a single horizontal raceway that carries the LEDs, the Class 2 low-voltage driver, and a single electrical penetration through the building wall. The raceway simplifies installation, concentrates the electrical work into one rated entry point, and makes long-term service straightforward.

Does Plumb Signs serve Lakewood, University Place, and Fife?

Yes. Lakewood, University Place, and Fife are part of our daily service area from the Tacoma shop, along with Federal Way, Puyallup, Gig Harbor, Bonney Lake, Sumner, DuPont, and Steilacoom. Pierce County is our home market.

What does UL-listed mean for a sign?

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.

Who installs and services signs after fabrication?

Plumb Signs installs and services everything we build. Our installation crews handle structural anchoring, electrical hookup, and final commissioning on site, and our service team dispatches same-day from Tacoma for LED driver replacement, face repair, electrical troubleshooting, and storm damage across the South Sound.
