Outdoor signs are a constant, visible representation of a business; they communicate messages day and night. To keep them looking impeccable, it’s important to know how weather conditions affect them to prolong their lifespans.

Every material reacts differently to the elements. What keeps a vinyl banner looking bright in the summer might not protect a plastic yard sign during winter frost. Let’s explore some practical, seasonal tips for maintaining multiple types of outdoor signs, from A-frame signs on the sidewalk to pole signs towering over a parking lot.

Spring Cleaning for Your Signage

As winter recedes, it’s time to refresh your signs and prepare them for the warmer months ahead. Spring is a period of growth and renewal, and your outdoor signs should reflect that freshness.

Inspect for Winter Damage

The first step is a thorough inspection. Winter can be harsh, with cold temperatures, ice, and strong winds potentially causing wear. Check all your signs, including real estate and office signs, for any cracks, fading, or peeling. Look closely at mounting hardware and supports to see if they have loosened or rusted over the winter months.

Gentle Cleaning Techniques

After a long winter, your signs will likely have a layer of dirt and grime. Gentle cleaning can restore their appearance.

Vinyl

For vinyl signs, use a soft cloth or sponge with a solution of mild soap and water. Avoid abrasive cleaners or stiff brushes that could scratch the surface or damage the printed graphics. Rinse thoroughly with clean water to remove any soap residue.

Aluminum

Aluminum signs are durable, but they still benefit from a good cleaning. A simple mixture of water and a mild detergent is usually sufficient. For tougher spots, you can use a nonabrasive cleaner. Dry the sign with a soft cloth to prevent water spots.

Corrugated Plastic

Signs made from corrugated plastic, like many yard signs, are lightweight and easy to clean. Wipe them down with a damp cloth and a gentle cleaning solution. Because they are less rigid than aluminum or vinyl, handle them carefully to avoid bending or creasing the material.

Summer Care: Beating the Heat and Sun

Summer brings sunshine and increased foot traffic, making it a key time for your signs to look vibrant. However, intense sunlight and summer storms take a toll.

Shield From Sun Damage

The sun’s ultraviolet (UV) rays are a primary cause of fading for many sign materials. If possible, position your signs to get some shade during the hottest parts of the day. This is particularly important for brightly colored vinyl signs, which can lose their vibrancy with prolonged sun exposure.

Combat Summer Storms

Summer can also bring sudden, intense storms with heavy rain and high winds. For temporary signs like A-frames or yard signs, it’s a good idea to bring them indoors if a severe storm is in the forecast. For more permanent installations, like traffic or pole signs, regularly check that all fittings are secure to withstand strong winds.

Autumn Maintenance: Prepping for Colder Weather

Autumn is a transitional season, and it’s the perfect time to prepare your outdoor signs for the approaching winter.

Clear Away Debris

Falling leaves, twigs, and other organic matter can accumulate on and around your signs. This debris can hold moisture, which may lead to discoloration or mildew, especially on vinyl surfaces.

Regularly clear away any leaves or dirt that collect on the signs. A gentle sweep with a soft brush is all that’s necessary to keep your outdoor signs clean.

Check for Moisture Issues

Moisture becomes a problem as temperatures drop. Inspect signs for any areas where water might pool or seep in. For illuminated signs, check that all seals around electrical components are intact to prevent water damage. Addressing these issues in the fall can prevent more serious problems, like cracking from frozen water, during the winter.

Winter Protection: Guarding Against the Cold

Winter is the most challenging season for outdoor signage. Cold, ice, and snow force business owners to give their signs extra attention.

Protect From Ice and Snow

Heavy snow and ice can put physical stress on signs and their supports. After a heavy snowfall, gently clear accumulated snow from your signs, especially larger ones, to relieve the weight. Use a soft broom or brush, as hard scrapers can easily damage the sign’s surface. Be cautious with aluminum signs, as they can dent under heavy impact.

Material-Specific Winter Care

Different materials require specific approaches during the cold months.

Vinyl

Vinyl can become brittle in extreme cold, making it more susceptible to cracking or tearing. Avoid moving or rolling vinyl banners in freezing temperatures. If you need to store them, do so in a climate-controlled area.

Aluminum

Aluminum holds up well in the cold, but road salt used for deicing affect the material. If your signs are near a road, wipe them down periodically to remove salt residue, which can be corrosive over time.

Corrugated Plastic

Corrugated plastic could become fragile when temperatures drop. Handle them with care to avoid snapping or cracking.

For temporary signs, like party or event announcements, it is best to remove them after the event rather than leaving them out in harsh winter conditions.
