Even the best-installed hardwood basketball court can develop problems over time. Knowing what to look for and how to address issues early can save you from costly repairs. Here are the most common problems and their solutions.
Cupping is one of the most frequent issues. This is when the edges of the planks rise higher than the center, creating a concave shape. Cupping is almost always caused by moisture. Either there is too much moisture coming from below, or the humidity in the facility is too high. The solution is to identify and eliminate the moisture source. In many cases, cupping can be reversed by controlling the humidity and allowing the wood to acclimate. Severe cupping may require sanding and refinishing.
Gapping occurs when the planks separate from each other, creating visible gaps. This is usually caused by the wood drying out too much, which happens when humidity is too low. The solution is to increase humidity to the recommended range. In the short term, gaps can be filled with a flexible wood filler, but the underlying humidity problem must be addressed.
Buckling is a more serious problem. This is when the planks push up against each other and create ridges on the surface. Buckling is caused by excessive moisture trapped beneath the floor. It can be very expensive to fix because it often requires removing and replacing the affected planks. Prevention through proper vapor barrier installation and humidity control is the best approach.
Wear in high-traffic areas is normal but can become a problem if it is not addressed. The areas around the baskets, the free-throw lines, and the sidelines will wear faster than the rest of the court. If the wear becomes severe enough to affect ball response or player safety, the affected area should be sanded and refinished. Spot refinishing is much less expensive than refinishing the entire court.
Squeaking is another common complaint. Squeaks are usually caused by the wood rubbing against the subfloor or by loose fasteners. The solution is to inject a lubricant or adhesive between the layers or to re-fasten the loose planks. In some cases, adding a thin layer of material between the hardwood and the subfloor can eliminate the squeak permanently.
Finish wear is inevitable. Over time, the polyurethane or other finish will wear down, especially in high-traffic areas. When the finish no longer provides adequate traction or looks worn, it is time for a full refinish. Waiting too long can allow moisture to penetrate the wood, causing more serious problems.
The key to avoiding most problems is proper installation and consistent climate control. When these fundamentals are in place, hardwood floors are remarkably trouble-free.
