Sub-floor repairs Sydney, bearers and joist
New solid timber flooring installations are usually laid over flat surfaces like concrete slabs, plywood, particle boards, tiles, or existing boards. Another method of installation is utilizing existing timber joists and bearers. Many older homes in the Eastern and Inner Western suburbs of Sydney were built with the two components’ floor frame system. Floor joists and bearers.
- Sub-floor bearers or joists need to be strong enough to hold the rest of the floor up. Lack of floor vents in Sydney houses and prevailing moisture exposure can cause a range of changes to the joists and bearers for an extended period. Rising dampness, excessive moisture, lack of fresh air, and neglected sub-floor ventilation are the primary culprits of Sydney’s sub-floor repairs.

There are usually two main approaches.
1. Sufficient operating room underneath the floor. Enough space for the flooring guy to stand, sit, or at least physically be able to crawl underneath the floor.
In such a case, we will bring a new joist or bearer in and replace the faulty one. The most challenging part of the job is manipulating 3-4 m long floor members in confined space. We must place a waterproof flashing between the timber and the foundation to keep the bearers protected from moisture. A sheet of plastic or traditional lead flashing is used. The access to the sleeper wall must be provided to repair the issue from underneath the subfloor.
2. Not enough clearance between the soil and hardwood flooring. In this case, the flooring members repair must be carried out from the top of the customer’s tongue and groove floor.
The bad news is: The subsequent sanding and polishing of the natural timber usually go hand-in-hand with the repair. It means not only moving out the furniture from the room but often from the entire wood flooring area. Occasionally the sanding and polishing can be split into several jobs. However, the time required will be much longer. To provide the highest quality job, we need the whole hardwood floor to be sanded and finished simultaneously.
