8 Essential Tips for Maintaining Your Custom Signs

Your signage is often the first thing people notice about your business. It’s your brand on display 24/7, sending a message about your professionalism, quality and attention to detail. But even the most beautifully designed sign will lose its appeal without regular care. Sun, rain, wind and everyday grime can quickly wear away colours and legibility, leaving you with a faded or damaged sign that turns customers away instead of inviting them in.

Below are practical, easy-to-follow tips for maintaining your signage so it stays bright, effective, and professional over the long term.

1. Regular Cleaning for Maximum Impact

Regular cleaning is one of the simplest and most effective ways to extend the life of your signage. Dirt, dust, and pollution build up over time, dulling colours and reducing readability. Making cleaning part of your maintenance routine will keep your signs looking fresh and appealing.

• Use a soft sponge or cloth with mild soapy water to remove grime without scratching surfaces.
• Avoid harsh chemicals or abrasive cleaners, which can damage protective coatings or printed graphics.
• Rinse thoroughly with clean water to remove any residue.
• Dry with a lint-free cloth to prevent streaks or water spots.
• Consider engaging a professional service to ensure safe, thorough cleaning for larger signs or difficult-to-reach areas.

2. Protecting Signs from Harsh Weather

Australia’s weather can be tough on outdoor signage. Strong sunlight, rain, wind, and even salt air in coastal areas can cause fading, cracking or corrosion over time. Planning for these conditions is essential when maintaining your signs.

• Apply UV-resistant coatings or films to reduce sun damage and slow fading.
• Use weather-rated materials such as aluminium composite panels or marine-grade stainless steel for durability.
• Install signage in sheltered areas where possible to limit direct exposure.
• Add protective frames, backing boards or covers to shield edges from water ingress.
• Regularly inspect fasteners and fittings to ensure they’re secure and corrosion-resistant.

3. Inspecting for Damage or Wear

Even well-built signs can suffer damage over time. Small issues left unchecked can develop into costly repairs or complete replacements. Routine inspections help you identify problems early, keeping maintenance simple and affordable.

• Look for signs of fading, cracking or peeling graphics that could reduce readability.
• Check for rust, corrosion or loose fittings on metal components.
• Inspect illuminated signs for flickering lights or electrical faults.
• Examine bases and posts for signs of movement or instability.
• Identify any vandalism, graffiti or other damage that needs prompt attention.

Setting a schedule—perhaps quarterly or biannually—for these checks helps you stay on top of maintenance and avoid surprises.

4. Updating Graphics & Branding Elements

Your signage reflects your business identity, so it’s important to keep it up-to-date. Old logos, outdated colours, or faded designs can make your business look outdated or even confuse customers.

• Refresh logos and colour schemes to match your current branding.
• Update contact information, opening hours or website details as your business evolves.
• Modernise typography or layouts to improve visibility and readability.
• Replace worn, faded or cracked vinyl graphics with fresh, high-quality prints.
• Consider updating illuminated signs with energy-efficient LED lighting for better performance and cost savings.

5. Choosing the Right Materials for Durability

The materials used in your signage significantly affect its lifespan and maintenance needs. Investing in high-quality, appropriate materials is a smart way to reduce long-term costs and avoid constant repairs.

• Choose weather-resistant materials such as aluminium composite panels or UV-stable vinyls for outdoor use.
• Select impact-resistant acrylics for high-traffic or vulnerable areas.
• Use corrosion-resistant hardware like stainless steel screws and brackets to avoid rust.
• Opt for laminates or coatings that protect against graffiti, UV damage and abrasion.
• Match material choice to location—different environments demand different solutions.

Consulting with a professional signage company ensures you select materials suited to your specific conditions and needs.

6. Maintaining Illuminated & Digital Signs

Illuminated and electronic signs need extra care to ensure they work reliably and look great. A flickering light or blank screen doesn’t just look bad—it can actively harm your business’s reputation.

• Clean lightboxes and digital screens gently to avoid scratching or damaging sensitive surfaces.
• Check wiring, connections and power supplies regularly for wear or damage.
• Replace faulty bulbs or LED modules promptly to maintain consistent illumination.
• Inspect housing for signs of water ingress, corrosion or physical damage.
• Schedule professional servicing to test electrical components and ensure safety.

Investing in proper maintenance for illuminated signs means they’ll keep attracting customers after dark, maintaining your visibility and reinforcing your brand around the clock.

7. Scheduling Professional Sign Maintenance

While there’s plenty you can do yourself, professional maintenance services offer specialised expertise and tools that take your sign care to the next level. They can help you address issues you might miss and perform work you’re not equipped to handle.

• Conduct thorough, safe cleaning using specialist products.
• Inspect signs for hidden damage or early signs of wear you might overlook.
• Perform structural repairs to mounts, posts or brackets to ensure stability.
• Replace or update graphics with professionally printed, high-resolution materials.
• Offer tailored maintenance plans to keep your signage in prime condition year-round.

8. Planning for Long-Term Signage Investment

Good signage isn’t just a cost—it’s an investment in your business’s image and success. Planning for ongoing maintenance ensures you get the most value from that investment over its entire life.



• Budget for regular cleaning and inspections as part of your operating costs.
• Consider the total cost of ownership, including maintenance, when choosing materials and designs.
• Plan for periodic updates to branding and graphics to keep your image fresh.
• Work with a professional signage provider to create a maintenance schedule tailored to your business.
• Factor in local conditions such as climate, pollution or vandalism risks when designing and installing signs.
