A water stain by the dishwasher, a squeak in the hallway or gaps that open every winter usually has a cause, and that cause decides the right repair. Design Timber Flooring provides timber floor repairs across Sydney, assessing the existing floor, the reason for the damage and the matching material available before recommending a local repair or wider work.
Discuss the floor condition, repair options and written scope with Jimmy. We are a mobile service covering Greater Sydney, with free on-site quotes and a fixed-price written quote once the scope is clear.
Our repair service is for hardwood floors
Our repair and board replacement service is for hardwood floors: solid timber boards, typically Australian species such as Blackbutt, Spotted Gum, Brushbox and Sydney Blue Gum, including the older hardwood found in Federation, interwar and post-war Sydney homes.
Engineered timber, laminate and hybrid floors are a different conversation. Those repairs depend on the product's construction, locking system and whether matching planks are still available. If you have one of these floors, keep the product name or leftover boxes handy and discuss it with Jimmy, or read about our engineered timber flooring service if replacement is on the table. We will tell you honestly if a job sits outside what we repair.
Common problems and what we assess
The visible mark does not always establish the cause. Before any hardwood floor repair goes ahead, we look past the surface.
| Symptom | Likely causes | What we assess |
|---|---|---|
| Water marks, swelling or staining | Leaking appliance or plumbing, wet entry areas, pet accidents | Whether the source is resolved, moisture in boards and subfloor, extent of damage |
| Cupping | Moisture from below, poor ventilation, a past or ongoing leak | Subfloor conditions, moisture readings, whether boards can settle |
| Gapping | Seasonal shrinkage, dry indoor conditions, previous movement | Whether gaps are seasonal or permanent, board condition |
| Squeaks and loose boards | Loose fixings, joist or batten movement, boards rubbing | Fixing condition, what sits underneath, access |
| Cracked or split boards | Impact damage, age, unsupported sections | How far the damage runs, available matching boards |
| Missing flooring after a layout change | Wall or joinery removed, kitchen reconfigured | Board direction, species, width and how new meets old |
Leaks, pest activity and structural issues may require the relevant specialist, such as a plumber, pest inspector or builder, before flooring work proceeds. We discuss what needs to be resolved instead of covering an active problem.
Water damaged timber floor repair: fix the cause first
With water damage, the cause and current moisture conditions come before decisions about replacement boards. New boards laid over a subfloor that is still wet, or next to a leak that has not been fixed, are set up to fail. Our approach follows a simple order:
- Identify and resolve the source of the water, whether a dishwasher connection, a shower, a burst pipe or water tracking in from outside.
- Allow the area to dry and check moisture in the boards and subfloor before deciding what can be kept.
- Cut out the damaged sections back to sound timber and inspect the joists, bearers or battens underneath.
- Lace in matched boards and prepare the area for finishing.
Some boards that look alarming straight after a leak settle once they dry; others stay cupped, split or stained. We would rather check than guess.
See the hardwood repair photographs for the visible stages of existing work. Our water-damaged floorboard service explains the assessment and repair decisions.
Floorboard replacement and lacing in
Floorboard replacement usually involves lacing in: removing damaged boards at staggered lengths and fitting new ones so the end joins are spread across the floor, as in the original installation. A square cut-out may be quicker, but it tends to stay visible once finished. Good lacing in depends on:
- Cutting back to sound timber, not just the edge of the visible damage.
- Staggering joins so no straight line runs across the repair.
- Matching the tongue and groove profile so new boards sit flush.
- Securing boards properly to the joists or subfloor below.
See floorboard replacement and matching for how we source boards and blend the repair.
Sourcing matching species and width
Species, width, profile, grain and ageing affect the match. A floor laid decades ago may be a width that is no longer commonly milled, and older boards have darkened with years of light and finish.
We source suitable boards where available, whether new timber in the same species and dimension or reclaimed boards that suit the floor. Sometimes the best match comes from elsewhere in the house, such as a cupboard floor about to be covered by new joinery. Exact uniformity cannot be promised before assessment, especially where the existing floor has faded unevenly or a profile is unavailable. If your renovation joins new flooring to retained hardwood, read our seven decisions for matching existing boards.
Squeaky floorboards and loose boards
Squeaky floorboards are usually a sign of movement: boards rubbing together, a fixing that has worked loose or a joist that has shifted. We check where the movement comes from first. The fix may involve re-securing boards, addressing the support below or replacing a board that has split along its fixings. A floor over a crawl space can often be checked from underneath, while an upstairs floor needs a different approach. Not every squeak can be removed completely, but we will explain what is likely to last. Read more on fixing squeaky and loose floorboards.
Gaps and cupping in floorboards
Cupping and gapping floorboards are both usually about moisture. Timber swells and shrinks with the seasons, so some gapping in solid hardwood is normal, particularly in drier months or where heating runs for long periods.
Persistent cupping, where board edges sit higher than the centre, often points to more moisture below the floor than above it, from poor subfloor ventilation, a leak or damp ground under a raised floor. Sanding a cupped floor flat before the moisture is dealt with can cause problems later, because the boards may move again. We will not recommend filling or sanding as a cover for an active moisture problem. Our page on cupping and gaps in floorboards explains how we tell seasonal movement from a moisture problem.
Repair or wider replacement?
A local repair may suit contained damage where the surrounding hardwood is sound. Wider replacement may be appropriate where deterioration is extensive, there is insufficient usable timber left for sanding, or a compatible match cannot be sourced. The recommendation depends on the floor and your intended result.
We also offer sanding and polishing and new timber supply and installation, so the options can be discussed together.
Sanding and finishing after the repair
New boards are raw and usually lighter, the old boards carry years of finish, and the surfaces sit at slightly different heights. That is why a repair is typically followed by sanding and finishing across the whole area, not just the replaced boards. Sanding the room as one floor levels the surface so old and new timber take the same coating.
We discuss the finishing area needed to blend old and new work, which may be one room or connected spaces where the floor runs through a doorway. The result is matched as closely as the existing floor allows, and some colour difference may remain at first and soften as the new boards age. Our vacuum-assisted equipment reduces dust at the source, although no sanding process is completely dust-free. See examples in our hardwood repair and restoration photographs.
Timber floor repairs across Sydney
Many of the repairs we see are in older homes with original boards. We regularly assess Federation and terrace floors across the Inner West, kitchen and bathroom water damage in apartments and semis in the Eastern Suburbs, and the original hardwood in established North Shore homes. Wherever you are across Greater Sydney, it starts with the same on-site assessment.
What happens next?
- Inspect the hardwood and discuss the cause and extent of the problem.
- Establish the repair scope, available materials and any prerequisite work.
- Replace or secure the agreed boards and prepare the finishing area.
- Apply the appropriate finish and provide return-to-use instructions.
Timing and the finishing scope vary by project. When you get in touch, have your suburb, photographs of the damage and any information about the existing hardwood ready. Afterwards, our guide to caring for a timber floor helps keep it in good condition.
Frequently asked questions
Do you repair engineered, laminate or hybrid floors?
Our repair and board replacement service is for hardwood floors. Engineered, laminate and hybrid repairs depend on the specific product, its locking or fixing system and whether matching planks are available. Tell Jimmy the product name if you know it and he can talk through whether replacement is the more practical option.
Can you match new boards to my existing floor?
We source suitable boards in the same species, width and profile where available. Grain, ageing and uneven fading all affect the match, so exact uniformity cannot be promised before assessment. Sanding and finishing the area together helps the repair blend as closely as the existing floor allows.
My floor got wet. Should I replace the boards straight away?
Not usually. The source of the water needs to be fixed first, and the boards and subfloor need to dry before anyone can tell which boards will settle and which need replacing. Take photographs, stop the leak and arrange an assessment.
Can squeaky floorboards be fixed?
Many squeaks can be reduced or fixed by finding where the movement comes from, whether that means re-securing boards, dealing with the support below or replacing a split board. Not every squeak can be removed completely, and we will explain what is likely to make a lasting difference.
Why are my floorboards cupping or gapping?
Both are usually linked to moisture. Seasonal gapping is normal as solid hardwood shrinks in drier months. Cupping often means more moisture under the floor than above it. We assess the cause first, because sanding or filling without dealing with moisture can lead to further movement.
Will the repaired area need to be sanded?
Usually, yes. New boards are raw and sit slightly differently to the existing floor, so the area is typically sanded and finished as one floor. The finishing area may be one room or connected spaces where the floor runs through.
Do you offer floor repair near me?
We are a mobile service covering Greater Sydney, from the Eastern Suburbs and Inner West to the North Shore, Sutherland Shire and Western Sydney. Jimmy comes to your property for a free on-site assessment, so there is no showroom to visit.
