Subfloor Repair in Melbourne
The National Construction Code describes the subfloor space as the space between the underside of the floor and the ground surface under a building. In Victoria the Building and Plumbing Commission describes the class of domestic builder limited to re-stumping and re-blocking as sub-floor works for homes. This site refers subfloor repair enquiries on to an independent provider, who inspects and quotes.

What subfloor repair in Melbourne actually involves
The Commission says that class involves levelling and supporting existing structures to ensure they have solid foundations. Among the activities an applicant for it must show experience in, the Commission lists replacing defective sub-floor members and flooring. That is a description of a registration class and not of a repair method: nothing we read says how a member is repaired or when it must be replaced.

What the code sets for a new subfloor
For new work, the code's Housing Provisions require openings in the external and internal subfloor walls, a subfloor cleared of building debris and vegetation, and ground beneath the floor graded to suit. They apply to all suspended floors, timber or steel-framed, and to suspended concrete slabs. Whether Victoria varies them, or they govern repair of an existing house, we could not establish — so ask a provider what the finished subfloor will be built to.
In Victoria the Domestic Building Contracts Act 1995 applies to the repair of a home. Every domestic building contract carries the Act's warranties, among them that the work is done in a proper and workmanlike manner, in accordance with the plans and specifications in the contract, and in compliance with all laws. A later owner of the building can take proceedings for a breach as if a party to the contract.

Subfloor Repair in Melbourne — common questions
What does the National Construction Code say about subfloors?
For new work it requires openings in subfloor walls and a subfloor cleared of debris and vegetation. Whether it governs the repair of an existing house is not established here.
Can the walls around a subfloor affect the ground under a house?
CSIRO says saturation of clay foundation soil may occur where subfloor walls create a dam that makes water pond. Ask a provider what happens to water around the space.
