How Much Does Garden Decking Repair Cost?

Rotted boards, a wobbly frame, or a patch of decking that dips after a wet winter can turn a nice outdoor space into a costly headache. If you’re wondering whether a small repair will do the job or if you’re facing a bigger bill, this GardenCost.com guide breaks down the numbers.

How Much Does Garden Decking Repair Cost in the UK?

Most garden decking repairs in the UK cost £150–£1,500, depending on whether you’re replacing a few boards, fixing the subframe, or re-levelling the whole area. Light repairs may stay under £300, while more extensive structural work can reach £2,000+ if rot or movement is widespread.

As with many Cost Guides in Decking and Patios, the final price depends on access, material type, and how much of the deck can be saved. Minor cosmetic repairs are far cheaper than work involving joists, posts, or a failing base, especially if the deck is attached to a raised area or sits near a boundary with Fencing & Walls.

What Affects the Cost of Garden Decking Repairs?

The biggest cost driver is the type and extent of damage. A couple of split boards are usually simple to replace, but if the timber below has started to rot, the repair becomes more involved. Moisture damage is common in the UK climate, particularly where water sits under the deck or drains poorly after rain.

Material choice also matters. Softwood decking is generally cheaper to repair because boards are lower cost and easier to source, with replacements often priced at £20–£40 per board. Hardwood or composite decking can cost more, with individual boards or planks often ranging from £40–£120 each, and specialist trims or clips adding extra expense.

Access is another factor. If installers need to lift heavy sections, work around built-in steps, or move Garden Buildings, planters, or hot tubs, labour time increases. Decking with difficult access can cost 10%–30% more than a straightforward ground-level repair.

The condition of the supporting structure is crucial too. If joists, bearers, or support posts are compromised, the repair may involve more than board replacement. In some cases, what looks like surface wear is actually a subframe issue, which can push the job from a few hundred pounds to £800–£2,000 or more.

If the deck has shifted because the ground has moved, you may also need related work such as levelling or drainage improvements. It can be worth reading a related guide like How Much Does Garden Levelling Cost in 2026? if your decking has become uneven after settlement or waterlogging.

Average Price Breakdown by Repair Type and Material

Here’s a practical breakdown of typical garden decking repair costs in the UK:

Board replacement: £80–£250 for a small area, or £200–£600 for several damaged boards. This usually includes removing failed boards, preparing the area, and fitting new ones.

Step or edge repair: £120–£350. Steps, fascia boards, and perimeter sections often cost more per metre because they take longer to cut and fit neatly.

Subframe repair: £300–£1,200. This might include replacing joists, bearers, or support timbers where rot, corrosion, or movement has weakened the structure.

Re-levelling: £250–£900. A deck that has dropped or begun to slope may need packers, new supports, or partial lifting and resetting.

Full deck refurbishment: £800–£1,800. This can be the best middle ground when the frame is salvageable but the surface needs a major tidy-up.

Composite decking repairs: £200–£700 for smaller jobs, but costs can rise because matching boards are not always easy to source and hidden-fixing systems take longer to dismantle and refit.

Softwood decks usually offer the cheapest repair route, while hardwood and composite decks tend to carry higher material costs but may last longer once properly fixed. In some cases, repairs to a deck may be comparable to other outdoor surface projects, such as Patios & Paving maintenance or edging repairs, but the structure beneath the boards is often more important than the visible surface.

Labour Costs and What Installers Usually Charge

Decking repair labour in the UK commonly falls between £25–£45 per hour, or around £180–£350 per day for a carpenter, landscaper, or general Garden Services contractor. More specialist joinery work, or repairs involving structural timber, may be priced higher.

Small board replacement jobs often take 2–4 hours, while moderate repairs may take a half day to a full day. If sections need removing carefully to preserve surrounding boards, or if hidden fixings are corroded, labour time rises quickly. A straightforward repair might cost £150–£400 in labour, while larger structural work can run from £500–£1,200.

Expect extra charges where waste removal, sourcing matching materials, or return visits are needed. Some contractors will include a call-out or minimum charge of £75–£150, especially for smaller jobs that don’t fill a full day.

If the deck repair is part of a larger outdoor project, such as replacing nearby paving, adding screening, or updating access around the garden, the contractor may offer better value by bundling jobs together.

When Repair Makes Sense vs Full Replacement

Repair usually makes sense when the damage is localised and the frame is still solid. If only a few boards are cracked, warped, or stained, you can often restore the deck for a fraction of the replacement price. This is particularly true for decks that are otherwise dry, level, and securely fixed.

Signs that repair is likely worthwhile include isolated soft spots, surface weathering, one or two loose boards, squeaking fixings, and minor movement at the edges. In these cases, you might spend £150–£600 and gain several more years of use.

Full replacement becomes more sensible when rot is widespread, the subframe is failing, or the deck has repeatedly moved after wet weather. If more than 30%–40% of the boards need changing, or if the support structure is badly compromised, replacement can offer better long-term value. A full new deck may cost £1,500–£4,500+ depending on size and material, but it can avoid repeated repair bills.

Look carefully for the key signs of rot, movement, and weather damage: spongy timber, dark staining around fixings, mushrooming screw heads, cracking near board ends, loose handrails, sagging sections, and persistent puddling. If these signs are concentrated in one area, repair may be enough. If they are spread across the deck, replacement often makes more financial sense.

How to Save Money and Get the Best Value

The cheapest repair is not always the best value. Aim for a fix that addresses the cause, not just the symptom. For example, replacing a rotten board without dealing with drainage or ventilation may lead to the same problem returning in a year or two.

To keep costs down, try to catch issues early. Replacing one or two damaged boards at £80–£200 is far cheaper than allowing moisture to spread into the frame. Clear leaves, improve airflow underneath the deck, and keep soil or mulch from touching timber edges. Regular checks are especially important after storms, frost, or prolonged rain.

Get materials matched before work starts if possible. This is particularly helpful for older decks where the original profile may be discontinued. If you’re using timber, pressure-treated softwood is usually the most budget-friendly choice, while composite can be more expensive upfront but may reduce future maintenance.

Ask contractors whether they can repair only the affected section rather than lifting the full deck. Partial repairs are often significantly cheaper, especially if the deck is large. Also ask whether the quote includes fixings, waste removal, and any sealant or treatment needed after the repair.

It can also help to compare the deck job with other outdoor maintenance costs from Garden Buildings to Fencing & Walls, because many contractors price small tasks differently depending on whether the work is standalone or part of a larger visit. Bundling jobs may reduce the overall call-out cost.

For the best value, get at least three written quotes, check that each contractor explains what is being repaired and why, and look for someone who has experience with decking, not just general garden maintenance. A good contractor should be clear about materials, labour, warranties, and whether the repair is expected to be a temporary fix or a long-term solution.
