How to Maintain a Home Tennis Court in the UK: Seasonal Care Calendar

Owning a home tennis court is a significant investment, but with a structured maintenance routine, you can keep it in excellent playing condition for years. The UK climate presents particular challenges—wet winters, variable spring weather, and concentrated summer use all demand different care approaches. A seasonal calendar ensures you tackle the right tasks at the right time, preventing costly damage and keeping your court safe and playable.

Spring: Deep Clean and Repair Assessment

March through May is your critical preparation window. After winter weather, your court needs thorough inspection and cleaning.

Start with a complete surface sweep to remove winter debris: leaves, algae growth, and moss that thrives in damp conditions. Use a stiff-bristled broom, working systematically across the whole surface. For stubborn growth, a pressure washer on a low setting (below 100 bar) works, but avoid high pressure, which can damage the court binding.

Inspect the court surface for cracks, loose material, or areas where water's pooling. Pooling indicates drainage issues—the most common problem with UK courts in spring. Check that your perimeter drains aren't blocked with leaf matter. Clear guttering and downpipes if you have them.

Spring is also the time to assess net condition. Check tension, inspect tape for fraying, and look for rust on metal posts in coastal areas. A sagging net or corroded posts should be addressed before the season proper.

If your court is acrylic, spring is the ideal time for repainting. Most acrylic surfaces need repainting every 3–5 years, depending on use and weather exposure. This is labour-intensive but essential for both playability and longevity—paint protects the underlying structure from UV and water damage.

Summer: Regular Maintenance and Minor Repairs

June through August sees peak usage, so focus on keeping the surface clean and preventing damage during play.

Weekly light sweeping removes debris that can scratch shoes and affect ball bounce. After heavy use, brush off dust and loose grit. Following rain, allow the court to dry fully before playing—wet surfaces are slippery and harder to maintain.

Keep a sharp eye for divots, loose material, or cracks that develop during the season. Small surface cracks can be addressed with flexible repair compound specifically formulated for your court type. Catching these early prevents them expanding through frost action come winter.

Summer is low-risk for algae growth (though damp, shaded courts remain vulnerable), but you may see some residual moss edges that can be cleared with a stiff brush. Avoid chemical treatments unless absolutely necessary; they can damage the playing surface and harm surrounding vegetation.

Check your line markings. If they're becoming faint, note this for autumn remedial work. Most courts need line repainting every 2–3 years.

Autumn: Drainage Preparation and Surface Protection

September through November is your second critical maintenance window. Autumn weather—wet, variable, increasing leaf fall—demands preparation.

Clear the court of leaves and debris regularly. Autumn storms can leave significant accumulation that traps moisture and promotes algae growth. A leaf blower is invaluable here; systematic clearing once or twice weekly prevents problems later.

Thoroughly clean and unblock all drainage channels and perimeter drains. This is non-negotiable in the UK—poor drainage causes most winter damage. If you have a sump, check it's working and clear any sediment. If your court's base is clay or other permeable material, standing water over winter will cause surface breakdown.

Autumn is the time to address moss and algae more aggressively. Stiff brushing or a pressure washer on very low settings can remove surface growth. Allow treated areas to dry fully—avoid playing on damp treated surfaces as chemicals may be slippery.

Inspect your net posts and fencing. Repair or treat any rust spots before winter. Check that fencing is secure; winter winds can stress weak points.

Consider having a professional contractor assess your court if you're noticing persistent water pooling or surface degradation—a small investment here can prevent expensive remedial work later.

Winter: Protection and Minimal Use

December through February is low-maintenance in principle but critical in practice. Your goal is preventing damage, not active improvement.

Avoid playing on frozen courts—frost damage compounds existing problems. If ice forms, don't use salt (it damages surfaces). Allow natural thaw.

Keep clearing debris and standing water. Even in low-use periods, water pooling causes problems. After heavy rain or snow, clear channels and check the sump.

Winter's not the time for major repairs or repainting—weather makes work impossible. However, it's an excellent time to plan spring work: photograph problem areas, note what needs addressing, and arrange contractors if needed.

Very light sweeping can continue, but avoid aggressive pressure washing during freezing conditions. Ice can form in cracks you've just cleaned.

Year-Round Essentials

Regardless of season, maintain basic records. Note when you've swept, drained, carried out repairs, or repainted. Over months and years, these records show patterns—perhaps your court's always prone to pooling in specific areas, or certain corners need earlier winter preparation.

Keep maintenance equipment accessible: a decent broom, soft-bristled brush, a stiff-bristled brush for moss, and a moisture meter to assess whether courts are truly dry. A simple leaf net or blower saves hours.

Finally, be realistic about your court's condition. A well-maintained court remains playable indefinitely, but if you're noticing widespread cracking, persistent pooling despite drainage work, or significant surface deterioration, a professional evaluation is worth the cost. Small problems addressed promptly are far cheaper than major resurfacing.
