Joists & Bearers Replacement | Floor Experts
Joist & Bearer Replacement in Sydney Structural Timber Floor Repairs
This type of work is very common in older Sydney homes where structural timbers have deteriorated due to age, moisture, or termites. Revitalize your home with our specialized joists and bearers replacement services, ensuring a safe and sturdy foundation for your timber floors.
Signs Your Joists or Bearers May Need Replacing
If you are experiencing any of the following issues, joist or bearer replacement may be required rather than surface-level repairs
- Floors feel bouncy or springy
- Sagging or sloping timber floors
- Cracks appearing in walls or ceilings
- Doors or windows no longer closing properly
- Visible termite or moisture damage
- Bearers resting on soil, bricks, or failed piers
- Floor movement noticed after renovation or wall removal
Structural Joist & Bearer Replacement – Not a Surface Repair
Joists and bearers are load-bearing structural elements that support the entire timber floor.
When they are damaged, undersized, or poorly supported, surface fixes will not resolve the underlying problem.
In many Sydney homes, joist and bearer replacement is required due to termite damage, moisture exposure,
age-related deterioration, or incorrect original construction. These issues are common in older properties
with suspended timber floors and limited subfloor ventilation.
Proper structural repair requires opening the floor, exposing the framing, and rebuilding the support system
correctly. Simply packing, screwing, or patching over damaged timbers may provide a short-term improvement,
but does not address the root cause of floor movement.
Our Joist & Bearer Replacement Process
- Structural inspection and floor assessment
We assess floor levels, movement, and load distribution to determine the extent of structural damage. - Selective floor opening
Floorboards are carefully lifted where required to expose joists, bearers, and subfloor conditions.Floor openings are kept to the minimum required to assess and repair the structure correctly. - Assessment of subfloor conditions
We inspect ventilation, moisture levels, termite damage, and existing supports to identify contributing issues. - Removal of damaged joists and bearers
Failed or compromised structural timbers are removed safely without unnecessary disturbance to surrounding areas. - Installation of new treated structural timbers
New joists and bearers are installed, packed, and fixed correctly to restore structural integrity and floor stability. - Re-levelling and preparation for floor reinstatement
The structure is levelled and prepared for reinstating flooring, floor leveling, or surface restoration.

Related Structural & Floor Services
Joist and bearer replacement is often part of a broader structural repair or floor restoration project.
Once the structural framework has been repaired, many floors require additional work to achieve a stable, level, and finished result.
Depending on the condition of the subfloor and flooring, we regularly carry out
underfloor repairs to address ventilation, moisture issues, or failing supports before reinstating the floor structure.
After structural repairs, floors commonly require
floor leveling to correct movement or unevenness caused by long-term joist or bearer failure.
Where existing timber flooring is being retained, clients often proceed with
floor sanding and polishing once the structure is stabilised, restoring the surface after repairs are completed.

We regularly carry out joist and bearer replacement in older Sydney homes, particularly properties built between the 1920s and 1970s with suspended timber floors.
These homes often suffer from inadequate subfloor ventilation, moisture exposure, termite activity, or structural movement over time.
Many structural issues are discovered during renovations, wall removals, or when floor surfaces are being upgraded.
In these cases, repairing or replacing joists and bearers correctly is essential before any new flooring or surface restoration can proceed.
Our experience working in areas such as the Inner West, North Shore, and Eastern Suburbs allows us to identify common structural floor issues quickly and recommend appropriate repair methods based on the property type and subfloor conditions.
