Troubleshooting

Flooring problem guides

Start here when a floor is clicking, lifting, separating, sounding hollow, showing carpet seams, or causing transition problems.

What to do first

Start with the jobsite conditions: identify the flooring type, mark where the problem repeats, check for moisture or movement, and avoid forcing repairs before the cause is clear.

Troubleshooting by flooring type

Start with the material and symptom, then use the related calculator or prep guide to narrow the likely cause.
