Spring is in the air, with longer days, milder temperatures and the return of outdoor sports creating a renewed sense of energy. This seasonal transition is the ideal time to focus on getting your courts in shape to ensure the surface promotes play, remains safe and stands up to increased use throughout the warmer months.
Based on Lawn Tennis Association data and industry estimates, the UK has between 23,000 and 25,000 tennis courts, including 20,000 outdoor facilities. Participation reached record levels leading into 2026, with 2.6 million adults playing monthly and 5.6 million occasionally in 2025. More than 3.6 million children have played within the past year, with 700,000 taking part once a week.
The LTA reports that tennis has experienced a “significant surge”, making it one of the most popular and gender balanced sports in the UK, with 41% of players being female. As courts begin to see more activity, it’s the perfect time to prioritise maintenance of playing surfaces.

Why spring court cleaning is crucial
Winter in the UK can be particularly tough on outdoor tennis courts with persistent rain, frost, occasional snow and fluctuating temperatures all taking their toll. Moisture seeps into small cracks, freezes, expands and then thaws, gradually weakening the surface. At the same time, debris such as leaves and dirt accumulates, while moss and algae thrive in damp, shaded conditions.
Neglecting wear and tear can have serious consequences: a poorly maintained court leads to inconsistent ball bounce and slower surfaces, while increasing the risk of slips and injuries. Courts covered in moss and dirt become dangerous very quickly.
A thorough clean of the playing surface will remove organic matter that has accumulated over winter. Otherwise, it can lead to deeper surface issues, such as weed growth through cracks. Once moss becomes well established, it’s harder to remove, so tackling the problem early in the season makes ongoing maintenance more effective.
During drier periods, simple brushing to remove loose debris can help, but for stubborn build-up, professional treatments are more beneficial. Tarmacadam courts, which make up around 60% of playing surfaces in the UK, are particularly valued for their durability and relatively low construction costs. However, they’re not immune to damage.
Repairing issues early helps maintain the integrity of the court and prevents further deterioration. Left untreated, small cracks can widen and will require more extensive and expensive resurfacing work.
Tennis court lining to improve visibility
Clear, accurate court lines are essential for fair and enjoyable play. After months of harsh weather, lines can fade, become obscured by dirt, or lose their crisp definition. Refreshing the markings is a key part of spring maintenance. According to International Tennis Federation standards, a tennis court should be 23.77 metres long and 8.23 metres wide for singles play, or 10.97 metres for doubles. The lines themselves are typically white and 50mm wide.
Ensuring these markings are clearly visible and correctly applied is not just about aesthetics, as it directly impacts gameplay. Players rely on precise dimensions for judging shots, as unclear boundaries can lead to frustration and disputes.
Tennis court marking for compliance and safety
Beyond visibility, professional marking plays an important role in meeting recognised standards. In the UK, tennis court markings are typically aligned with LTA guidelines, which suggest non-slip criteria for safety. Modern marking materials often feature slip-resistant and anti-glare properties to reduce potential hazards.
Using high-quality materials ensures they can withstand the demands of regular play throughout the busy tennis season, while minimising the risk of slips and ensuring the court meets professional standards.
Accuracy during application is critical. Even slight deviations can affect gameplay, particularly for more competitive players who rely on consistent court dimensions.
Checking for drainage issues
Winter rainfall can expose or worsen drainage problems leading to puddles, waterlogging, or uneven surfaces.
Poor drainage doesn’t just interrupt play – it can significantly damage the court over time. Standing water increases the likelihood of cracks forming and encourages the growth of moss and algae, compounding surface issues.
Ensure drainage systems are functioning correctly and that the court surface allows water to run off effectively to preserve its condition. Addressing any issues early in the season can prevent ongoing problems during wetter summer periods.
Benefits of regular cleaning and maintenance
Regular upkeep brings a range of long-term advantages. A clean court creates a more inviting and professional environment, which is particularly important for clubs, schools and shared facilities. It also supports health and hygiene standards, reducing the presence of organic growth.
From a practical standpoint, consistent maintenance extends the lifespan of the court, as it delays the need for costly resurfacing further down the line. It can even improve lighting efficiency, as removing dark build-up enhances surface reflectivity.
There are also important safety and compliance considerations, as a properly maintained court reduces the risk of accidents and can support insurance requirements, providing protection in the event of injury claims.
As the UK moves into the warmer months, tennis courts are set to become hubs of activity again. Whether it’s a friendly rally, a coaching session, or a competitive match, the quality of the court plays a central role in the whole experience. Ultimately, it’s about making the most of the season ahead, as there’s nothing quite like stepping onto a freshly prepared court on a bright spring day and getting back into sport.
