Quick answer

Rotten timber repair involves cutting back decayed timber to sound material, identifying and fixing the moisture source, then replacing the affected members with treated or durable-class timber and reinstating the finish. On the Gold Coast the usual causes are wind-driven rain into unsealed end grain, failed deck and balcony waterproofing, ground contact, and long-term humidity in poorly ventilated subfloors.

Overview

Timber rot on the Gold Coast is rarely where people first see it. A soft deck board is a symptom; the joist beneath it has usually been wet for far longer. A blistered paint patch on a window reveal is often the visible end of decay that runs back into the frame. The first job is therefore diagnosis, not repair. We probe the surrounding timber to find the boundary between decayed and sound material, then trace the water back to its source - an unsealed cut end, a failed flashing, a deck that drains toward the house, a garden bed banked against a wall, or a subfloor with blocked vents. Replacing rotted timber without fixing the water path simply buys three or four years. We are equally direct about when repair is not the right answer. Splicing a new section into a bearer is legitimate engineering practice; patching filler into a structurally compromised post is not.

What's included

  • Probe and moisture assessment to establish the true extent of decay
  • Identification of the water source causing the damage
  • Removal of decayed boards, joists, bearers, posts and framing
  • Splice repairs and full member replacement in treated or durable timber
  • Termite damaged framing replacement and reinstatement
  • Window and door reveal, jamb and sill repairs
  • Fascia, barge board and eaves timber replacement
  • Deck and stair structural repairs including stringers and handrails
  • Sealing, priming and painting of new and cut timber
  • Preventative detailing - flashings, drainage falls, ventilation, end-grain sealing

Why timber fails faster here

Three Gold Coast conditions accelerate decay. Humidity keeps timber moisture content high year round, so material that would dry out in a southern climate stays in the range where fungal decay is active. Summer storms drive rain horizontally into joints, end grain and under flashings that would shed vertical rain fine. And salt-laden air corrodes fixings, so nail and bracket failure often accompanies the timber failure, particularly within a few kilometres of the beach and around the canal systems. The practical result is that external timber here needs correct species and treatment selection, sealed end grain, and fixings appropriate to the exposure classification - not just whatever was cheapest at the time it was built.

Rot, water damage and termite damage are different problems

Fungal decay needs sustained moisture and shows as soft, crumbly or spongy timber, often with a darkened or cubed appearance. Water damage without established decay may only need drying, sealing and repainting. Termite damage leaves the surface intact while the timber is hollowed out behind it, and is usually found by probing or by tapping and hearing the change. The distinction matters because the remedy differs. Termite damage requires a licensed pest management technician to deal with the colony and the barrier before there is any point replacing timber - we work alongside the pest inspector rather than replacing framing into an untreated situation.

Repair or replace

We assess this member by member. Localised decay in a long bearer or a stair stringer can often be spliced with a new section scarfed or bolted in, provided the remaining timber is sound and the connection detail carries the load. Where more than roughly a third of the cross section is compromised, where the decay is at a bearing point, or where the same member has already been repaired once, full replacement is the honest answer. For decks, there comes a point where the cumulative cost of replacing boards, joists and fixings exceeds the value of rebuilding the frame properly - we will tell you when you are approaching it rather than sell you a fourth round of patching. See our deck repairs page for how we work through that decision.

Insurance, rentals and reports

Sudden water damage - a storm event, a burst pipe, a failed flexible hose - is often claimable, while gradual deterioration generally is not. Where a claim is in play we document the damage and provide an itemised scope in the format insurers expect, and we work with assessors regularly through our insurance repairs service. For rental properties, rotten decking, stair treads and handrails are a safety issue under a lessor's obligation to maintain the premises in good repair. We provide property managers with photo-documented quotes suitable for sending straight to the owner for approval.

Signs you have timber decay, not just weathering

  • Deck boards or stair treads that flex or feel soft underfoot
  • A screwdriver pushes into the timber with light pressure
  • Paint blistering or lifting in a localised patch, particularly at joints and end grain
  • Dark staining that does not sand back to clean timber
  • Fungal growth, a musty smell under the house or visible mud tubes on piers
  • Rusted or loose fixings, brackets pulling away, handrails that move
  • Doors and windows sticking where the frame has moved

Our process

  1. 1

    Site inspection

    We attend the property, inspect the actual condition rather than working from photos alone, and talk through what you want the finished result to be. Bring any reports, strata approvals or insurance paperwork you already have.

  2. 2

    Written fixed-price quote

    You receive an itemised quote covering labour, materials, rubbish removal and any engineering or certification required. Where the full extent of damage can only be confirmed once linings or decking boards come off, we say so up front and quote the investigative stage separately rather than hiding it in an allowance.

  3. 3

    Approvals and scheduling

    Where certification, an engineer's design or body corporate approval is needed, we organise it and book the works into a dated program so you know which days we are on site.

  4. 4

    Carry out the works

    Protected floors, dust control, tidy site each afternoon and photo updates as we go. Occupied homes, tenanted properties and trading businesses are all worked around rather than shut down where possible.

  5. 5

    Handover

    Final walkthrough, defect check, invoice and any documentation - engineering certificates, Form 16s, product warranties - handed over with the job.

Frequently asked questions

Should rotten timber be repaired or replaced?

It depends on how much of the cross section is affected and where. Surface decay on a non-structural element can often be cut out, treated and made good. Decay at a bearing point, in a structural member, or through more than about a third of the timber should be replaced. We assess each member on site and tell you which category it falls into rather than applying one rule to the whole job.

Can filler be used on rotten timber?

Epoxy repair systems have a legitimate place on non-structural elements such as window sills and decorative mouldings where the surrounding timber is sound. They are not a substitute for replacing a decayed bearer, joist, post or stringer, and we will not use them that way.

How much do rotten timber repairs cost on the Gold Coast?

It varies far too widely to quote blind, because the visible damage is rarely the full extent. A handful of deck boards is a small job; a deck frame with decayed bearers and corroded fixings is a rebuild. We inspect, probe the extent, and give you a fixed-price quote covering what we can see plus a clear statement of what might be found once material is removed.

Do you fix the cause as well as the damage?

Always. Every repair scope we write identifies the water path that caused the failure and includes the detailing to correct it - drainage falls, flashings, ventilation, end-grain sealing or ground clearance. Replacing timber without that is a temporary result and we would rather not put our name to it.

Do you handle termite damaged framing?

Yes. We replace termite damaged structural and non-structural timber, working alongside a licensed pest management technician who deals with the colony and the barrier first. Replacing framing before the termite management side is resolved is money wasted.

Do you work on tenanted and investment properties?

Regularly. We coordinate access with the property manager or tenant, provide photo-documented quotes for owner approval, and complete works with minimal disruption. See our rental property repairs page for how that process runs.
