Subfloors support every interior finish. Trades know that ignoring subfloor conditions leads to squeaks, movement, and premature surface failure. Proper repairs protect the entire renovation investment.
Evaluation begins after demolition. Exposed subfloors reveal damage, moisture issues, and unevenness. Early assessment guides repair scope.
Structural integrity comes first. Soft or damaged sections must be replaced, not patched. Solid support prevents deflection.
Leveling ensures finish alignment. Uneven subfloors cause gaps and lippage. Leveling compounds or shimming correct irregularities.
Fastening improves stability. Loose panels are secured to framing to eliminate movement and noise. Proper fastening spacing is critical.
Moisture control protects materials. Damp subfloors damage finishes. Trades address moisture sources before proceeding.
Material compatibility matters. Repair materials must match existing subfloor type. Mismatched materials cause movement issues.
Expansion gaps must be respected. Subfloors require room to move without stressing finishes.
Sound control enhancements improve comfort. Underlayments reduce noise transfer between levels.
Transition planning ensures smooth flooring changes. Proper transitions prevent cracks and wear.
Clean surfaces support adhesion. Dust and debris reduce bond strength. Trades prepare surfaces thoroughly.
Inspection before covering is essential. Confirming repairs prevents hidden failures.
Subfloor quality determines finish performance. Trades never rush this phase.
Conclusion: Interior subfloor repairs succeed when trades address structure, level, moisture, and fastening to support durable, quiet finishes.
