Warped or buckled hardwood floor
Answer: call a carpenter.
Warped or buckled hardwood floors are typically caused by moisture imbalance — either a water leak underneath, high humidity, or improper installation without adequate expansion gaps. Individual boards may cup, crown, or lift away from the subfloor. A carpenter or flooring specialist can assess the moisture source, repair or replace affected boards, and re-sand and refinish the area.
