Causes of Tennis Court Damage
A low spot on the court, also known as a birdbath, will leave mineral deposits and should be repaired.
Tennis courts are cherished spaces for recreation, competition, and community gatherings. Whether located at a public park, school, club, or private residence, these courts see a wide range of activity from players of all ages and skill levels. However, tennis courts are subject to wear and tear like any outdoor facility over time. Understanding the causes of tennis court damage is essential for anyone responsible for their care. As professionals in tennis court maintenance and repair, we see firsthand how various factors can impact the appearance and playability of these valuable surfaces.
The importance of routine maintenance
A well-maintained tennis court can provide years of enjoyment and safe play. Regular care preserves the court’s appearance, extends its life, and reduces the need for costly repairs. Unfortunately, many court owners and facility managers underestimate the importance of routine maintenance until visible damage appears. By then, the issues may have progressed beyond simple fixes.
Lack of cleaning and maintenance
One of the most preventable causes of tennis court damage is neglecting basic cleaning. Leaves, pine needles, twigs, and other debris can quickly accumulate, especially during the fall or after storms. When left on the surface, this organic matter breaks down, leading to stains, discoloration, and even surface deterioration.
Regularly sweeping or using a blower every week or two, particularly during heavy usage periods, helps keep the court from debris. Professional services can also provide periodic deep cleaning to remove stubborn stains and prevent buildup. When cleaning is overlooked, the result is unsightly staining and a surface that becomes slippery and hazardous for players.
Algae, mold, and mildew
Moisture is a constant threat to outdoor tennis courts. Food and drink spills, decaying leaves, and trash left on the court create the perfect environment for algae, mold, and mildew to thrive. These organisms not only discolor the surface but also make it dangerously slick.
Mold and mildew can develop quickly in shaded or poorly drained areas, especially after periods of rain or humidity. Besides being unsightly, these growths can cause respiratory issues and increase the risk of slips and falls. Professional cleaning services use specialized products and equipment to safely remove algae and mold without damaging the court’s surface.
Improper drainage system
Water is a tennis court’s worst enemy. Without a properly designed and maintained drainage system, rainwater and irrigation runoff can pool on the surface or seep beneath the court, leading to a host of problems, including surface bubbling, cracks, and even structural instability.
A well-installed drainage system diverts excess water from the court, protecting the surface and the underlying foundation. Regular inspections ensure drains remain clear of leaves, debris, and sediment. If you notice standing water after rain, it’s crucial to have a professional assess the drainage system and make necessary repairs. Ignoring drainage issues can result in expensive restoration or even reconstruction.
Birdbaths and puddling
Birdbaths are small depressions or low spots on the court where water collects after rain. These are often caused by improper paving, settling of the base, or repeated freeze-thaw cycles. Birdbaths make the court unsightly, create slippery hazards, and promote mold and algae growth.
Addressing birdbaths typically involves patching or resurfacing the affected area to restore proper slope and drainage. Professional assessment is important to determine whether the issue is surface-level or indicative of deeper structural problems.
Using improper cleaning equipment
The tools and products used to clean a tennis court matter as much as the frequency of cleaning. High-pressure washers can damage certain court surfaces, particularly synthetic or cushioned systems, by eroding the top layer or dislodging the fiber mat. Similarly, harsh chemicals may strip away protective coatings or cause discoloration.
Professional contractors use soft-bristled brushes, approved cleaning solutions, and equipment specifically designed for tennis courts. This ensures thorough cleaning without unintentional damage. When in doubt, consult a professional before cleaning the court yourself.
Surface damage from improper use
Tennis courts are designed for foot traffic in appropriate footwear—specifically, clean, non-marking tennis shoes. Unfortunately, it’s not uncommon to see people riding bikes, rollerblades, skateboards, or even dragging heavy objects like benches and chairs across the surface. These activities can cause gouges, scratches, and tears that compromise the court’s integrity.
A common question is: Can you roller skate on a tennis court? While it may be tempting, roller skates and similar equipment can leave marks and indentations and even cause expansive cracking over time. For the longevity of the court, it’s best to reserve the surface for tennis and similar racquet sports.
Vandalism, though less frequent, can also result in significant damage, from graffiti to intentional gouging or burning of the surface. Prompt, professional repair is essential to restore the court and prevent further deterioration.
Cracks and expansive cracking
Cracks are one of the most common forms of tennis court damage. They often start as minor hairline fractures caused by regular use, temperature fluctuations, or minor settling of the base. Over time, these cracks can widen and multiply, especially if water seeps in and freezes during cold weather.
Expansive cracking may indicate more serious underlying issues, such as soil movement, root intrusion, or foundation failure. Addressing cracks early with professional patching and sealing can prevent them from spreading. For severe or widespread cracking, resurfacing or even reconstruction may be necessary.
Root damage
Trees and shrubs planted too close to a tennis court can cause significant problems as their roots grow beneath the surface. Root intrusion can lift or buckle the court, creating dangerous uneven areas and contributing to cracking. Once roots have compromised the foundation, repairs can be extensive and costly.
Professional assessment and root barrier installation are the best ways to prevent and address this issue. In some cases, removing nearby trees or relocating landscaping may be required to protect the court.
Trash and improper waste management
Trash left on or near the court—such as food wrappers, bottles, or cans—can attract pests, promote mold growth, and contribute to staining. Installing and maintaining adequate tennis court trash cans encourages proper disposal and helps keep the area clean. Regular emptying and cleaning trash cans are also important to prevent overflow and windblown debris.
Environmental factors and outdoor tennis court flooring
Outdoor tennis court flooring is exposed to sun, wind, rain, and temperature extremes. UV rays can cause fading and breakdown of surface coatings, while freeze-thaw cycles can lead to heaving and cracking. Professional-grade materials and coatings are designed to withstand these challenges, but even the best surfaces require periodic maintenance and resurfacing.
