Common Signage Issues and How to Fix Them

Why Signage Maintenance Matters for Your Business

Your signage isn’t just a display—it’s a powerful branding tool that shapes how customers perceive your business. Whether it’s an illuminated storefront sign, wayfinding sign, or digital display, your signs work around the clock to attract customers, communicate information, and create a professional image. However, weather conditions, electrical failures, and material wear over time can compromise your signage’s visibility and effectiveness.

A faded, peeling, or flickering sign can make your business look neglected or outdated, potentially driving customers away. Worse, improperly maintained signage can lead to compliance issues, safety hazards, or complete sign failure. Regular maintenance ensures your signs stay vibrant, functional, and aligned with your brand identity.

At BlinkSigns, we help businesses maintain their signage with expert repairs, routine upkeep, and durable signage solutions. Whether fixing minor wear-and-tear, replacing outdated components, or full sign restoration, we ensure that your signage always delivers the right impression.

This guide breaks down the most common signage issues, how to fix them, and when to call the professionals to protect your investment.

Identifying Common Signage Issues Based on Type

Different types of signage face specific challenges depending on their materials, location, and exposure to elements. Recognizing early warning signs can help prevent minor problems from escalating into costly replacements.

1. Structural & Surface Issues

Outdoor and indoor signs face unique structural risks that affect their readability and durability.

• Fading Colors & Sun Damage – Long-term UV exposure breaks down pigments, causing vinyl graphics, printed banners, and painted surfaces to fade or discolor.
• Peeling Vinyl Graphics & Lettering – Poor adhesive quality, heat exposure, and moisture can cause vinyl lettering and window graphics to bubble, lift, or crack.
• Scratches & Surface Damage – High-traffic areas often lead to scuff marks, scratches, and abrasions on metal, acrylic, and plastic signage.
• Rust and corrosion on Metal Signs—Humidity, rain, and pollution accelerate rust formation, leading to structural weakening and reduced visibility.
• Cracked or Broken Acrylic & Glass Panels – Impact damage, vandalism, or rapid temperature shifts can cause glass or acrylic signage to crack or shatter.
• Warping & Expansion Due to Temperature Changes – Wooden and plastic signs may expand, warp, or bend when exposed to extreme heat or cold.
• Graffiti and Vandalism Damage—Businesses in high-traffic urban areas often face defaced signage, which must be cleaned quickly to maintain a professional image.

2. Electrical & Illumination Issues

Lightning signs require consistent power, working components, and visibility to function correctly.

• Flickering LED or Neon Lights – Loose wiring, power fluctuations, or damaged LED modules can cause intermittent lighting issues.
• Dim or Uneven Lighting – Dirt buildup, faulty bulbs, or power supply problems can reduce the brightness of backlit signs, making them hard to read at night.
• Power Failures in Digital & Backlit Signs – Burned-out transformers, circuit failures, or weather exposure can cause full sign outages.
• Overheating of LED Components – Poor ventilation and prolonged usage can lead to overheating, reducing LED lifespan.
• Battery Backup Failures in Exit Signs—Emergency exit and wayfinding signage must remain operational during power outages. Dead backup batteries violate safety regulations.

3. Environmental Factors Affecting Signage Longevity

Outdoor signs are constantly exposed to harsh environmental elements that accelerate wear and tear.

• Extreme Weather Conditions (Rain, Wind, Snow, Heat) – High winds can loosen mounting brackets, and heavy rain can cause water damage to digital displays.
• Coastal Humidity & Salt Exposure—Businesses near coastal areas experience faster corrosion of metal signage, leading to early deterioration.
• Bird and insect Damage—Birds often nest in large pylons or illuminated signage, while insects can damage electrical components or block visibility.

DIY Fixes for Common Signage Issues

1. Restoring Faded Colors & Preventing UV Damage

Over time, UV exposure causes fading, making your sign less visible and harder to read.

How to Fix:

• Clean signage regularly using a mild detergent and a soft cloth to remove dirt buildup.
• Apply UV-resistant protective coatings or anti-fade sprays to prevent further deterioration.
• Consider replacing vinyl graphics or repainting surfaces with UV-resistant ink for signs with severe fading.

2. Fixing Peeling Vinyl Graphics & Lettering

Vinyl graphics can peel or bubble due to moisture, poor installation, or age.

How to Fix:

• Use a heat gun or hairdryer to reattach peeling vinyl, softening the adhesive for better adhesion.
• Apply vinyl adhesive for minor fixes, but consider a full replacement if large sections are damaged.
• Ensure the surface is clean and dry before applying new vinyl graphics.

3. Repairing Scratches & Surface Damage

Scratches on acrylic, metal, or glass signage reduce legibility and aesthetic appeal.

How to Fix:

• Use a polishing compound to buff out minor scratches for acrylic or plastic signs.
• For metal signs, sand and repaint scratched areas with weather-resistant paint.
• Apply protective coatings to reduce the risk of future damage.

4. Treating Rust & Corrosion on Metal Signs

Rust forms quickly in high-humidity areas, damaging structural integrity and aesthetics.

How to Fix:

• Use a rust remover spray and wire brush to eliminate surface corrosion.
• Apply a corrosion-resistant coating or repaint the sign with weatherproof sealant.
• For severely rusted metal signs, consider replacement with aluminum or stainless steel signage for long-term durability.

5. Fixing Water Damage & Sealing Signage

Water damage affects wooden signs, digital screens, and neon signage.

How to Fix:

• Re-seal wooden signs with weatherproofing coatings to prevent moisture absorption.
• Inspect LED signs for water damage, ensuring all electrical connections remain dry.
• Install drainage holes in large outdoor signs to prevent water buildup.

6. Electrical Signage Fixes: Replacing LED Modules & Repairing Wiring

A failing LED module or loose wiring can result in dim, flickering, or non-functional lighting.

How to Fix:

• Replace burned-out LED modules or neon tubes for consistent illumination.
• Check power sources and circuit connections for loose wires or damage.
• Ensure electrical enclosures are sealed properly to prevent moisture infiltration.

Safety & Legal Considerations for Signage Repairs

While DIY signage maintenance can address minor issues, some repairs require strict safety measures and legal compliance. Mishandling electrical components, improper cleaning solutions, or failing to follow local regulations can lead to further damage, safety hazards, or code violations.

1. Safety Precautions for DIY Signage Repairs

When attempting DIY fixes, follow these best practices to prevent injuries and further damage:

• Turn off the Power Before Working on Electrical Signs. Always disconnect LED or neon signage from power sources before cleaning or repairing components.
• Use Ladders & Scaffolding Safely – For high-mounted signs, ensure ladders are secure and stable, or use professional scaffolding when necessary.
• Wear Protective Gear—Wear gloves, safety glasses, and protective clothing when handling glass, chemicals, or electrical wiring.
• Avoid Harsh Cleaning Chemicals – Strong solvents can damage vinyl graphics, acrylic surfaces, and painted finishes. Stick to mild detergents and non-abrasive solutions.
• Follow Manufacturer Guidelines – Consult the signage manufacturer’s maintenance manual before using any cleaning or repair tools.

2. Legal & Compliance Factors for Signage Maintenance

Signage regulations vary by location, industry, and sign type. Ensure all repairs and updates comply with local signage laws and building codes.

• ADA Compliance – Businesses must ensure that directional, safety, and wayfinding signage remains visible, readable, and accessible to all users, including those with disabilities.
• Electrical Safety Regulations – Faulty electrical signage must be professionally repaired to comply with the guidelines of OSHA and NEC (National Electrical Code).
• Permits for Large Signage Repairs – Some monument, pylon, or building-mounted signs require permits for modifications or replacements.
• Fire Safety Codes – Exit signs and emergency lighting must always be functional to meet fire department and building code regulations.

Failure to meet these regulations can result in fines, legal issues, or forced signage removal. If you’re unsure about compliance, BlinkSigns can assess your signage and ensure all repairs meet legal standards.
