Signs of Long Island — Your Local Commercial Sign Experts
Serving Nassau and Suffolk County businesses with professionally designed, fabricated, and installed commercial signage for over 15 years.
The Long Island Sign Guy
Signs of Long Island is a full-service commercial sign company based in Deer Park, NY, with a second location in Riverhead serving the East End. We specialize in helping local businesses, franchise operators, property managers, and contractors get the right signage — on time, on budget, and fully permitted.
Our shop handles everything in-house: custom design, municipal permit applications, fabrication, and professional installation. Whether you need illuminated channel letters for a retail storefront, a full vehicle wrap fleet for your service company, a monument sign for your office park, or window graphics for your boutique — we've done it thousands of times across every town from Lynbrook to Montauk.
We're built for Long Island businesses. We know the permit offices, the zoning boards, and the unique visibility challenges of the Island's commercial corridors. When you work with us, you get a team that acts as your partner from first sketch to final install — not just a vendor who ships you a sign.
