Safe Stairs Need Structural Support
We often get asked to simply screw a loose step back down so the homeowner can keep using the deck immediately. While we understand the desire for a quick fix, structural safety is an integrated system. Screwing a new tread into a rotting side beam (stringer) makes the stairs highly vulnerable to sudden collapse under body weight.
To ensure the staircase is truly safe and visually consistent, stairs repairs must be immediately followed by a neutralising wash, sanding, and the right nourishing finish. That’s why we focus on complete restoration, ensuring the job is done properly from start to finish.
The Stairs Repairs Process
Proper stairs repairs is about much more than just nailing down a loose piece of wood. It requires careful load calculation, the right geometry for comfortable stepping, and a meticulous installation approach to ensure the new stairs blend seamlessly. Here is exactly how we repair your deck access.
Structural Assessment & Stringer Check
You can’t replace a stair tread safely if the supporting frame is rotting. Fixing timber to decaying wood will splinter the new boards, create deep structural flaws, and ruin the staircase entirely. Before any new wood is laid, we manually extract old screws, carefully cut away the damaged section, and inspect the structural stringers for hidden rot. This ensures a completely safe foundation and protects the structural integrity of the access point.
Timber Sourcing & Tread Cutting
Once the structure is prepped, we source premium replacement timber—whether it’s Merbau, Spotted Gum, or Treated Pine. This stage is designed to seamlessly match the specific width and profile of your existing deck. Our goal here is to return the stairs to a flawless state, cutting the new treads to exact lengths and routing the front edges evenly (nosing) without compromising the visual flow of your outdoor space.
Precision Fixing & Levelling
Laying the new tread leaves the step solid, but installation must be precise. The final step is a careful levelling and fixing process. We ensure consistent gaps for water drainage, pre-drill the hardwood, and secure the boards using 316 marine-grade stainless steel screws. Proper fixing is crucial—it allows the new timber to expand naturally rather than warping, twisting, or popping screws out of the step surface.

Common Questions About Deck Stairs Repair
Repairing deck stairs can be an intrusive process if not handled correctly, resulting in uneven or unsafe steps. Below are the answers to the most common questions we receive about replacing timber stairs in Sydney. If you have a specific concern about your deck's safety, feel free to reach out.
My deck stairs feel bouncy when I walk on them. What causes this?
A bouncy staircase is a major safety warning. It almost always means that the “stringers” (the diagonal timber beams that support the steps) have rotted, or that the top connection point where the stairs meet the deck has broken away. This requires immediate structural repair before the stairs collapse.
Can you just replace one broken step?
Yes, if the rest of the staircase and the supporting stringers are completely solid and free of rot, we can easily extract a single cracked or warped tread and install a matching piece of premium hardwood.
Are there building regulations for deck stairs?
Absolutely. The Building Code of Australia (BCA) has strict regulations regarding the “rise and run” (the height and depth of each step) to ensure they are safe and comfortable to use. When we rebuild or repair your stairs, we guarantee that the dimensions and geometry meet all current safety standards.
Will the new steps look different from my old deck?
We always source the exact same timber species as your original deck. However, because your existing timber has weathered, the brand-new treads will initially look different. The best way to blend them seamlessly is to have us perform a full chemical strip, wash, and oil across the entire deck and stairs once the repairs are finished.
