A cracked board in the hallway, a patch of floor where a wall used to be, or a gap left behind after the kitchen island moved. In each case, the goal is the same: new timber that sits with the old floor rather than looking like an afterthought. Floorboard replacement in an existing hardwood floor comes down to two things done well, sourcing boards that suit the floor and fitting them so the repair follows the pattern of the original installation.
Design Timber Flooring is a mobile, owner-operated business working across Sydney. Jimmy has been working on Sydney timber floors since 2006, and he is the one who assesses the floor, sources the boards and fits them. Quotes are free and on site, with a fixed-price written quote once the scope is clear. This page goes into detail on replacing and matching boards; for the wider service, see our full timber floor repairs service.
When boards need replacing
Most replacement jobs fall into a few groups:
- Damaged boards: split, cracked, gouged, burnt, deeply stained or soft from water or pet accidents.
- Worn-through boards: boards sanded so many times over the years that little timber remains above the tongue.
- Renovation gaps: flooring missing where a wall, fireplace hearth, kitchen bench, island or built-in robe has been removed.
- Old patch repairs: previous repairs in the wrong species, width or direction that stand out.
Lacing in, not patching
A square patch is quick, but its straight cut lines tend to show. We lace in instead: damaged boards come out at staggered lengths, and new boards are fitted so end joins spread across the floor like the original installation.
In practice that involves:
- Marking out the damaged area and extending the cuts back to sound timber.
- Staggering the cut lines so no two end joins line up across neighbouring boards.
- Removing the old boards carefully to avoid damaging the tongues and grooves of those staying.
- Fitting new boards with the right profile, then fixing them to the joists or subfloor below.
- Checking heights so the new boards sit as flush as possible with the existing floor.
It is fiddly work, and it makes the difference between a repair you notice and one you have to look for.
Sourcing matching species, width and profile
A good match depends on more than species. Jimmy looks at:
- Species, such as Blackbutt, Spotted Gum, Brushbox or Sydney Blue Gum, and whether the floor is a mix of species, which is common in older homes.
- Width and thickness, measured from a removed board where possible.
- Profile, the tongue and groove shape, and whether the boards were face-nailed or secret-nailed.
- Grade and features, such as gum veins, knots and colour range.
- Age and colour, because years of light and finish darken timber.
Where possible, we source new boards in the same species and dimensions through trusted Australian suppliers. If you have leftover boards from the original installation, or timber of your own, we can assess whether it suits. Our species pages on Blackbutt and Spotted Gum show how those timbers look and age.
Older floors, imperial widths and recycled boards
Many Federation and interwar homes in Sydney were floored in boards milled to imperial sizes. Those widths and thicknesses do not always line up with what is commonly milled today, so a new board straight off the shelf may be slightly too wide, too narrow or too thin.
Recycled hardwood boards of a similar age and size can be a good match where suitable stock is available, and new boards can sometimes be machined to suit. Sometimes the best boards come from inside the house, such as a robe or an area about to be covered by joinery, with that hidden area then filled with new timber. We work out the most practical option once we have seen the floor and measured the boards.
Filling gaps after a wall comes out or the kitchen changes
Opening up a living area or moving a kitchen often leaves bare joists, a hearth or a strip of sheeting where the wall or cabinetry sat. Filling it well means working out:
- Which way the existing boards run and how the new section will join them.
- Whether the gap needs framing or subfloor work first, which may be a job for your builder.
- How the new boards will be staggered into the existing floor instead of butting up in a straight line.
If a larger area of new flooring is joining retained hardwood, our article on matching existing hardwood floorboards walks through the decisions involved.
What Jimmy checks on site
- The species, width, thickness and profile of the existing boards.
- How much sandable timber is left on the existing floor.
- The cause of the damage, so new boards don't go straight back into a problem.
- The condition of the joists, bearers or subfloor in the repair area.
- The direction of the boards and the best places to stagger cuts.
- Whether matching boards are available new, recycled or from elsewhere in the house.
- How far the sanding and finishing should extend to help the repair blend.
Repair or replace?
Replacing a handful of boards makes sense where the rest of the floor is sound and has enough timber left for a sand and finish. A wider replacement may be the better choice where damage is spread through the room, where the floor has been sanded down to the tongue, or where a suitable match cannot be sourced. If water damage caused the problem, the cause needs fixing first, as our page on repairing water-damaged floorboards explains. We give an honest view of which option suits your floor and your plans.
Why a sand and finish usually follows
New boards arrive raw and usually lighter in colour. The existing floor has years of coating and ageing, and its surface may sit at a slightly different height. Sanding the whole room, or the connected area, as one floor brings the surface level and lets old and new timber take the same coating. Our sanding and polishing service covers this step, using vacuum-assisted machines to reduce dust at the source.
Expect some colour variation. New boards are often lighter than timber that has aged for decades. The difference usually softens with exposure to light, but we never promise an identical match before seeing the floor and the replacement stock.
Engineered, laminate and hybrid floors
Board replacement here is for solid hardwood floors. Engineered, laminate and hybrid planks depend on whether the exact product is still available and whether its locking system allows a single plank to be swapped. Keep the product name handy and talk to Jimmy, or read about engineered timber flooring if a new floor is on the cards.
Floorboard replacement across Sydney
Jimmy works as a mobile service across Greater Sydney. Matching older boards is a regular conversation in Federation homes on the North Shore, including established streets in suburbs such as Wahroonga, and in terraces and workers' cottages across the Inner West, where renovations often join new work to original floors.
Frequently asked questions
Can you replace just one or two floorboards?
Yes, where the rest of the floor is sound. Damaged boards are cut out back to sound timber and new boards are laced in, then the area is usually sanded and finished so the repair blends with the surrounding floor.
Will new boards match my old floor exactly?
We aim for the closest match the existing floor allows, matching species, width and profile where available. Older boards have darkened with age, so new boards often look lighter at first. The difference usually softens over time, but an identical match cannot be promised before assessment.
My boards are an old size. Can you still match them?
Often, yes. Older Sydney homes were frequently floored in imperial sizes that are less common today. Options include recycled boards of a similar size, machining new boards to suit, or reusing boards from a hidden area of the house. We measure and assess before recommending one.
Can you fill the floor where we removed a wall?
Yes. We look at board direction, the subfloor in the gap and how to stagger new boards into the existing floor. If framing or subfloor work is needed first, that may be a job for your builder.
Do I need to sand the whole room after replacing boards?
Usually that gives the best result, because sanding as one floor levels old and new boards and lets them take the same finish. Sometimes connected rooms need to be included where the floor runs through a doorway. We discuss the finishing area during the quote.
Do you replace engineered or hybrid planks?
Our board replacement service is for solid hardwood. Engineered, laminate and hybrid repairs depend on product availability and the locking system. Share the product name and Jimmy can talk through the realistic options.
Send photos of the boards you need replaced
Take a few photos of the damaged boards, a wider shot of the room and, if you can, a close-up of a board's end or edge, then send them with your suburb through our quote request page. Or call Jimmy on 0404 906 432 to arrange a free on-site assessment.
