How Much to Replace Floorboards? A Practical Cost Guide

When a floorboard starts to move, split, sag or creak, most homeowners ask the same sensible question: how much to replace floorboards, and is it really necessary?

The honest answer is that the cost depends on what is actually wrong beneath your floor. Replacing one damaged floorboard is very different from dealing with rotten joists and floorboards across a whole room. That is why a good quote should never be based on guesswork alone.

This guide gives you a practical UK cost guide, including average cost, labour costs, material choices and the factors affecting the cost of replacing floorboards. It will also help you understand when to repair or replace, when a DIY job may be reasonable, and when it is safer to call in a professional.

 

Quick Answer: How Much Does It Cost to Replace Floorboards?

As a rough guide, the cost to replace one floorboard may be around £80 to £250, depending on access, timber type and whether the replacement board needs cutting, fitting and finishing.

Several damaged floorboards may cost £200 to £800. Replacing the floorboards across a whole room can range from £500 to £2,500 or more, especially in London, period homes or where joists also need repair.

Job	Typical cost
Replace one floorboard	£80 to £250
Replace several boards	£200 to £800
Replace floorboards in a room	£500 to £2,500+
Labour per day	£200 to £350

Check trade gives useful ballpark figures for the cost of replacing joists and floorboards, but treat any online figure as guidance, not a final price. The real answer depends on the floor condition, access, materials and whether hidden structural damage is found.

 

Key Takeaways

Floorboard replacement costs depend on materials, labour, floor size and what is underneath.

Localised damage is usually far cheaper than replacing an entire floor.

Rot, damp, woodworm or a weakened joist can increase the cost significantly.

Period homes often need reclaimed timber if the repair is going to blend in properly.

A proper inspection is the safest way to understand much it will cost before work begins.

 

What Affects the Cost of Replacing Floorboards?

The main factors affecting the cost are the size of the damaged area, the type and quality of the wood, the age of the property, and how easy the floor is to reach.

A small area of your floorboard under carpet is usually simpler than boards trapped beneath fitted cabinetry, laminate, engineered flooring or a tiled finish. In older homes, especially a terraced house with suspended timber floors, the subfloor may also need checking.

Timber species matters too. Softwood is generally cheaper and more common in older houses. Hardwood floorboards cost more, and matching old wood flooring can take more time. The quality of the wood also matters, because cheap replacement floorboards may move, split or look wrong beside the existing floor.

The biggest cost change usually happens when a joist is damaged. If floor joists are rotten, damp, undersized or loose, simply replacing a floorboard will not solve the real problem. For structural matters, guidance such as GOV.UK Approved Document is a useful reminder that floors are part of the building’s structure, not just the visible surface.

Average Floorboard Replacement Costs in the UK

The cost per m² can vary widely because replacing floorboards is not always priced like normal flooring installation costs. A small repair may still take half a day once the tradesperson has travelled, lifted coverings, removed damaged timber, checked cutting lines, fixed the board and made the area safe.

Area	Estimated cost
Small bedroom	£500 to £1,200
Double bedroom	£800 to £1,800
Living room	£1,000 to £2,500+
Hallway	£400 to £1,200

The cost for replacing a single section of floorboard may look high compared with the size of the board, but the labour is often in the careful access, cutting, fixing and making good.

If you want guidance on London floorboard replacement, our floorboard repair service explains how repairs, joist support, reclaimed boards and finishing can work together.

 

Labour Costs Explained

Labour costs are usually the biggest part of the quote. A carpenter, joiner or flooring tradesperson may charge by the hour, half day or day. In many areas, you can expect to pay around £200 to £350 per day, with London and the South East often higher than the Midlands, North of England, Scotland or Wales.

The cost of hiring local tradespeople also depends on skill. A basic board replacement is one thing. Matching Victorian pine, dealing with movement, fixing creaky floorboards or strengthening a joist requires more judgement.

This is also why comparing only the cheapest cost per board can be misleading. The better question is what is being included: inspection, access, materials, joist checks, fixing method, sanding, finishing and waste removal.

 

Material Costs

Softwood floorboards are usually the most affordable option. Hardwood boards cost more, but may be needed where the existing wooden floor is oak or another hardwood.

Reclaimed timber is often the best choice in period homes because new floorboards can look too clean, sharp or pale beside older boards. Tongue and groove boards may also cost more to fit, especially where the surrounding boards need careful cutting.

Material	Typical use
Softwood	Older homes, pine floors, lower cost
Hardwood	Oak and higher-spec wood flooring
Reclaimed timber	Matching existing period flooring
Tongue and groove	Stable fitted boards and neat repairs

If the repaired area will later be sanded, sealed or blended into the wider room, it is worth thinking beyond the cost of materials alone. Our wood floor restoration service covers the wider process of repairs, sanding, refinishing and aftercare.

 

Signs Your Floorboards Need Replacing

You may need floorboard replacement if you notice rot, rotten floorboards, deep cracks, water damage, woodworm holes, loose floorboards, minor sagging or persistent movement underfoot.

Creaking floorboards are not always serious. Sometimes a squeak is caused by a loose fixing. But if the floor starts to sag, feels soft, or moves around a joist, it should be inspected properly.

Damp is especially important. Timber exposed to moisture can stain, move, decay and lose strength over time. Timber Development UK gives useful guidance on how moisture exposure can affect timber performance.

 

Repair or Replace? Which Is Better?

Repair	Replace
Lower cost	Higher upfront cost
Suitable for isolated damage	Better for widespread deterioration
Faster	More durable when damage is serious

A repair can be right when the floorboard is damaged in one area, the joist is sound, and the surrounding floor is stable. Replacement is usually better where boards are rotten, cracked, badly cut, heavily weakened or too loose to secure properly.

The right choice is not always the biggest job. It is the work that deals with the real cause.

 

Can You Replace Floorboards Yourself?

Replacing a floorboard can be a DIY job if the damage is minor and you understand what is underneath. You may need a try square and pencil, saw, drill, pilot holes, ring shank nails or cut floor brads, and the confidence to lift the board without damaging pipes or cables.

Common mistakes include cutting through services, using the wrong thickness board, ignoring damp, failing to repair the subfloor, or leaving the replacement floorboard poorly supported.

If you need to insert the replacement floorboard near pipes, cables, rot or damp, call in a professional.

 

What Happens During Floorboard Replacement?

A careful job usually follows a simple order:

1. Inspect the floor.
2. Lift coverings.
3. Remove damaged floorboards.
4. Check the joist and subfloor.
5. Repair or replace damaged timber.
6. Secure new floorboards.
7. Sand if required.
8. Finish or refit flooring.

In older properties, it is also worth checking whether the repair can improve comfort, draughts or sound transfer.

 

Hidden Costs to Consider

Hidden costs may include replacing floor joists, damp treatment, pest treatment, pipe or cable relocation, levelling, rubbish removal and decorating after repairs.

The Property Care Association notes that timber affected by fungal decay or insect attack may sometimes be retained and protected, but not always where safety or cost makes that unsuitable. Their timber preservation guidance is useful if you suspect rot or woodworm.

How Long Does Floorboard Replacement Take?

One board may take a few hours. Several boards may take one day. One room may take one to three days. A whole house will depend on access, condition and whether joists need attention.

 

How to Save Money on Floorboard Replacement

Replace only damaged sections where sensible.

Source reclaimed boards where matching matters.

Get more than one written quotation.

Combine repairs with renovation or sanding work.

Deal with creaks, cracks and damp before they spread.

For wider project planning, our floor restoration pricing page explains why floor costs depend on condition, layout, repairs, humidity, location and finish.

 

Choosing a Flooring Professional

Look for clear communication, relevant insurance, strong customer reviews, written quotations and a willingness to explain options plainly. If the issue may be structural, a surveyor may also be appropriate. RICS explains that a home survey can highlight defects, repairs and maintenance options, which can be helpful when buying or renovating a property. See the RICS home survey guide.

 

Conclusion

The cost of replacing floorboards depends on the real condition of the floor, not just the visible damaged board. A small section may be straightforward. Rotten joists, water damage or structural movement are different matters.
