Signs Unlimited is a full-service sign shop helping San Mateo businesses attract customers, reinforce their brand, and communicate clearly — from a single shop sign to a complete commercial signage system.
If you are a business owner in San Mateo searching for new commercial signage or looking to refresh an existing system, Signs Unlimited is your local sign company. We back that up with in-house design, fabrication, and installation — all handled by our own San Mateo sign makers.
As a dedicated sign shop serving the Bay Area, we produce San Mateo custom signs built around your brand identity, physical space, and marketing goals — not off-the-shelf templates. Every project starts with a conversation about what you need and what your customers respond to.
As a Signworld Partner, we combine the support of a national network with the responsiveness of a local team — serving single locations and multi-site businesses alike across the US and Canada.
Have a project in mind?
We offer free, no-obligation consultations — a focused conversation about your signage needs with no pressure to commit.
We have partnered with businesses across San Mateo in a wide range of industries. Whatever your sector, we design signage that speaks to your audience.
A local sign shop does more than print graphics — it provides strategy, compliance guidance, and installation expertise that online vendors cannot match. When you work with a San Mateo sign store that operates in your market, you get signage calibrated to local foot traffic, zoning regulations, and your specific building environment.
Unlike national chains, our sign store team visits your location, understands the context your signs will live in, and selects materials that hold up against the Bay Area’s coastal climate. That on-the-ground knowledge is what separates a sign that performs from one that merely looks good in a proof.
Whether you need shop signs that stop foot traffic on a busy street or interior wayfinding for a multi-floor office, we match the solution to the setting. Our team handles every stage in-house, so nothing gets lost between design, production, and installation.
As a full-service sign making company, we design and fabricate a complete range of indoor and outdoor signs — from illuminated channel letters on a building facade to subtle directory signs inside a lobby.
If you need a sale sign maker for seasonal promotions, retail window graphics, or a permanent monument sign at your entrance, our sign maker team builds each piece to your approved specifications using materials that match your timeline, budget, and durability requirements.
We source from established vendors, including 3M and Gemini, to ensure consistent quality across every sign. Substrates range from cast acrylic and brushed aluminum to precision-cut vinyl and PVC — selected based on your environment, exposure, and finish preferences.
Working with a profitable sign maker — one that understands your market, your customers, and your physical environment — turns signage from a line-item cost into a revenue-generating asset. As a locally rooted sign company San Mateo businesses have relied on across many industries, Signs Unlimited brings that knowledge to every project.
Our team designs, fabricates, and installs every sign we sell. We do not outsource production, which means consistent quality standards and a single point of accountability from your first brief to your final installation.
Every Americans with Disabilities Act (ADA) sign we produce meets current federal and California standards. Compliant signage protects your business from potential fines and demonstrates that your space is accessible to every visitor.
Exterior and illuminated signs in San Mateo require city approval. We manage permit applications and coordinate with local authorities on your behalf, keeping your project on schedule without adding that burden to your team.
We communicate your production schedule and installation window at project kickoff. You will know exactly when each milestone is due before any fabrication begins, so you can plan your own launch or reopening around it.
We incorporate greener materials and more responsible production practices wherever possible. It reflects our genuine commitment to the San Mateo community — not a marketing talking point.
As a San Mateo sign store, Signs Unlimited provides clear milestones from day one. Here is what to expect:
We learn your brand goals, location requirements, and budget to guide the project.
We visit your location to measure surfaces and identify specific zoning or permit needs.
Our in-house designers present concepts. We never start production until you approve the final design.
Your sign is crafted in our local shop, with clear lead times communicated upfront.
We manage all permit applications and city communications on your behalf.
Our crew handles the mounting, electrical connections, and site cleanup, finishing with a final walkthrough.
Whether you need a full exterior identity system or a single set of shop signs, our San Mateo sign makers are ready to help.
