Can floor gaps be fixed without repairing the foundation? 

In some cases, floor gaps can be fixed without repairing the foundation. This depends on the cause of the gaps and the extent of the damage. Simple solutions like filling filler materials or adjusting the flooring may be sufficient for minor gaps caused by natural settling or temperature changes. However, if the gaps are due to structural issues or foundation problems, repairing the foundation will be necessary to ensure a long-term fix.
