How to Fix an Uneven Subfloor Before Installing Flooring

Plymouth Hardwood Flooring explains proper subfloor leveling techniques essential for successful installations. Addressing uneven subfloors prevents flooring problems and ensures long-lasting performance in Plymouth homes.

Identifying Subfloor Problems

Use a long straightedge or level to detect high and low spots. Manufacturers typically require flatness within 3/16 inch over 10 feet. Document problem areas before beginning corrections.

Common Causes of Uneven Subfloors

Plymouth homes develop uneven subfloors from:

Settling foundations
Water damage and rot
Poor original construction
Inadequate joist support
Deteriorated subflooring materials

Leveling High Spots

Sand or grind high areas using belt sanders or concrete grinders. Remove material gradually, checking frequently with levels. Dust containment systems minimize mess during grinding operations.

Filling Low Spots

Self-leveling compounds work excellently for depressed areas. These products flow into low spots and cure level. Follow manufacturer mixing instructions precisely for proper results.

Using Floor Patch Compounds

Smaller depressions fill with floor patch products. Feather edges smoothly into surrounding subfloor. Allow complete curing before proceeding with flooring installation per product specifications.

Replacing Damaged Sections

Severely damaged subfloor sections require replacement. Cut out compromised areas and install new plywood or OSB matching existing thickness. Secure properly to floor joists.

Addressing Structural Issues

Some unevenness indicates serious structural problems requiring professional assessment. Sagging floors, large gaps, or continuing settlement need structural repairs before flooring installation.

Concrete Subfloor Solutions

Concrete floors use different leveling approaches. Grind high spots with concrete grinders. Apply self-leveling concrete for low areas. Ensure proper curing before flooring installation.

Minnesota Basement Considerations

Plymouth basement subfloors require moisture testing before leveling. Address moisture sources first. Install vapor barriers over concrete before applying leveling compounds.
