Understand why proper subfloor preparation is crucial for successful flooring installation and how our Sydney experts ensure optimal results.
Subfloor preparation is often overlooked by homeowners, but it's the most critical step in any flooring installation project. A properly prepared subfloor ensures your new flooring will perform optimally, look great, and last for years to come.
Subfloor preparation involves assessing, cleaning, leveling, and conditioning the surface that will support your new flooring. This process ensures:
Structural Integrity: Solid foundation for flooring materials
Moisture Control: Proper moisture barriers and ventilation
Level Surface: Even, smooth surface for installation
Clean Environment: Removal of contaminants and debris
Common in Sydney apartments and modern homes:
Moisture Testing: Essential for concrete subfloors
Leveling: Self-leveling compounds for uneven surfaces
Sealing: Moisture barriers to prevent damage
Curing Time: Proper drying before installation
Common in older Sydney homes:
Structural Assessment: Check for damage or deterioration
Screw Reinforcement: Secure loose areas
Leveling: Sanding or filling for smooth surface
Moisture Protection: Vapor barriers if needed
Traditional construction method:
Thickness Requirements: Minimum 19mm for most flooring
Grade Assessment: Structural grade plywood required
Fastener Check: Secure all loose areas
Surface Preparation: Sanding and cleaning
When installing over existing floors:
Compatibility Check: Ensure materials are compatible
Height Considerations: Door clearances and transitions
Adhesion Requirements: Proper bonding methods
Removal Options: Complete removal vs overlay
Calcium Chloride Test: Industry standard method
Relative Humidity Testing: More accurate for thick slabs
Acceptable Levels: Varies by flooring type
Remediation: Moisture mitigation if levels are too high
Pin-Type Meters: Quick moisture level checks
Acceptable Range: 6-12% moisture content
Seasonal Variations: Account for Sydney's humidity changes
Acclimatization: Allow materials to adjust to environment
Different flooring types have different requirements:
Laminate/Vinyl: 3mm over 3m span
Engineered Timber: 2mm over 3m span
Solid Timber: 1.5mm over 3m span
Carpet: 6mm over 3m span
Self-Leveling Compounds: For concrete subfloors
Plywood Overlays: For wood subfloors
Sanding: For minor irregularities

Mold/Mildew: Professional remediation if needed
Loose Fasteners: Secure all screws and nails
Damaged Areas: Replace or repair damaged sections
Squeaks: Identify and eliminate noise sources
Sagging: Address structural issues
Screw Reinforcement: Add screws every 150mm
Plywood Patches: Replace damaged areas
Bridging: Add support between joists
Professional Assessment: For major structural issues
