About Plumb Signs

At the heart of our work is a simple promise: to build signs that people are proud to stand beside — today, tomorrow, and a hundred years from now.

We specialize in custom aluminum monument signage designed for apartment complexes, housing authorities, and general contactors across California. Each sign is crafted with care, engineered for durability, and built to withstand the elements for decades.

Driven by craftsmanship, integrity, and value, we take pride not just in what we make — but in how we make it. From initial concept to final installation, we collaborate closely with our clients to ensure each sign reflects the character of the property and meets every practical need.

We don’t believe in shortcuts. We believe in doing it right — the first time — so your sign becomes a lasting part of the landscape.
