Even the best-installed, best-maintained hardwood basketball court can develop problems over time. Knowing how to identify and address common issues early can save you from costly repairs and keep your court in playing condition. This article covers the most common problems and their solutions.

Problem 1: Squeaking

Squeaking is the most common complaint about hardwood basketball courts. It is caused by movement between the hardwood planks and the subfloor, or between the subfloor and the concrete slab.

The solution depends on the cause. If the squeaking is caused by loose planks, the planks should be re-fastened. If it is caused by movement between the subfloor and the slab, construction adhesive or additional fasteners should be applied. In some cases, a lubricant such as powdered graphite can be applied to the joints to reduce friction.

Problem 2: Cupping and Crowning

Cupping (edges higher than center) and crowning (center higher than edges) are caused by moisture imbalance. When one side of a plank absorbs more moisture than the other, it expands unevenly, causing the plank to deform.

The solution is to identify and eliminate the moisture source. Once the moisture problem is resolved, the affected planks can be removed, acclimated to the correct environment, and reinstalled. In mild cases, screening and refinishing may be sufficient.

Problem 3: Gapping

Gapping occurs when the spaces between planks widen, usually during dry winter months when the wood shrinks. Small gaps (less than 1/8 inch) are normal and will close when humidity increases. Larger gaps indicate a moisture problem or insufficient expansion space during installation.

The solution for large gaps is to add a flexible wood filler to the gaps. The filler should be color-matched to the wood and flexible enough to move with the wood. For severe gapping, the affected planks may need to be replaced.

Problem 4: Finish Wear in High-Traffic Areas

The free-throw lane, the key, and the sidelines see the most traffic and will show finish wear first. When the finish wears through, the wood is exposed to dirt, moisture, and abrasion, accelerating the damage.

The solution is to recoat the finish in the affected areas. This is a localized recoating, which is less expensive and less disruptive than a full court recoating. If the wear has penetrated into the wood, the affected planks may need to be sanded and refinished.

Problem 5: Ball Bounce Inconsistency

Inconsistent ball bounce is usually caused by uneven wear, a worn finish, or a subfloor problem. It can also be caused by temperature or humidity fluctuations.

The solution is to inspect the floor for uneven wear and refinish or replace the affected areas. The subfloor should be checked for movement or unevenness. Climate control should be verified to ensure consistent temperature and humidity.

Problem 6: Staining and Discoloration

Stains on a basketball court can be caused by spills, rubber marks from shoes, or chemical reactions. Most stains can be removed with a hardwood-specific cleaner or by lightly sanding the affected area and refinishing.

Rubber marks are particularly common on the sidelines and under the baskets. They can be removed with a rubber mark remover or by applying a paste of baking soda and water.

Prevention Is the Best Cure

Most of these problems can be prevented with proper installation, climate control, and consistent maintenance. A daily sweeping routine, weekly mopping, and regular recoating will keep your court in top condition and prevent small problems from becoming big ones.
