Chicago Sign Company FAQs
- How much does a custom business sign cost in Chicago?
- Most storefront signs run from about $1,500 for simple dimensional lettering to $8,000+ for large illuminated channel letter sets. Interior signs and window graphics usually start a few hundred dollars. We give a firm written price after we see dimensions and photos of the space.
- Do you handle sign permits?
- Yes. We check local sign codes, prepare the drawings and file the permit application with the city or village, and follow it through to approval. Permit fees are billed separately at cost.
- How long does a sign take from order to installation?
- Typical projects run 2–4 weeks in fabrication. Permitting can add 2–6 weeks depending on the municipality. Window graphics and vehicle lettering are often finished in under a week.
- Do you make the signs yourself?
- Yes. Everything is fabricated in our own Chicago warehouse — no outsourcing to a third-party manufacturer — and installed by our own crew.
- What areas do you serve?
- Chicago and every surrounding suburb, including Norridge, Arlington Heights, Schaumburg, Naperville, Elmhurst, Oak Park, Skokie, Evanston, Des Plaines and Glenview.
- Can you match my existing branding?
- Yes. Send your logo files, brand colors or a photo of your current signage and we'll match fonts, colors and proportions so everything looks consistent.
- Do you repair or replace existing signs?
- We do. Common jobs include LED and power supply replacement, face repairs, repainting, re-facing a lightbox for a new tenant and removing old signage before a new install.
- Will a vehicle wrap damage my paint?
- No. We use cast vinyl that removes cleanly from factory paint in good condition, and we install in a controlled indoor bay.
- Are you licensed and insured?
- Yes — we're licensed and insured for sign installation, including lift work, and can provide a certificate of insurance for your landlord or property manager.
- How do I get a quote?
- Fill out the quote form on this page or call (224) 355-8717. Include the address, rough dimensions and a photo of the space, and we'll usually come back with pricing within one business day.
