A British winter is hard on garden furniture: it is not just the cold but the relentless damp, the freeze-thaw cycles and the weeks of low, weak sun that never quite dries anything out. Left uncovered from October to March, a teak dining set greys and splits, aluminium frames pit and stain, and cushions turn into mildew sponges. The good news is that proper winter protection takes an afternoon and a modest outlay, and it can add years to furniture you have already paid for. This guide walks you through cleaning, covers, storage, drainage and material-by-material care so your set comes out in spring looking almost as good as the day it arrived.
1. Why winter wrecks garden furniture
Most people assume frost is the main enemy. It plays a part, but the bigger culprit in the UK is trapped moisture. Our winters rarely stay below freezing for long; instead we get repeated cycles of wet, mild, wet, cold. Water seeps into timber grain, screw holes and the hollow legs of metal frames, then expands by roughly nine per cent as it freezes. Do that fifty times over a season and joints loosen, welds crack and wood fibres tear apart from the inside.
The second problem is biological. Mould, algae and mildew thrive at temperatures as low as 4°C wherever there is moisture and no airflow. A cushion left in a damp box, or a table covered so tightly that condensation cannot escape, will grow black mildew spots that are almost impossible to remove. That is why, counter-intuitively, a completely sealed cover can do more harm than no cover at all.
Finally there is UV and pollution. Even weak winter sun, combined with acidic rain and urban grime, slowly bleaches colour and etches soft coatings. Understanding these three threats — freeze-thaw, trapped damp and slow surface degradation — is the key to everything that follows. Protect against all three and your garden furniture will sail through to April.
2. Clean and dry before you store
Whatever you do next, never put furniture away dirty. Grease, food residue, tree sap and bird droppings are all mildly acidic or organic, and they will keep working on the surface all winter under a cover. A thorough autumn clean is the single most valuable half-hour you will spend.
Work through it in a logical order:
- Brush off loose debris — leaves, cobwebs and grit, especially from crevices and folding mechanisms.
- Wash with warm water and mild soap — washing-up liquid is fine for most materials. Avoid harsh detergents or bleach on timber and untreated metals.
- Rinse and, crucially, dry completely — wipe with a cloth then leave in the open air for a few hours on a dry day. Any moisture sealed in will condense under a cover.
- Treat before covering — this is the moment to oil timber or wax metal fittings while the surface is clean and bare.
Pick a genuinely dry, breezy day in October or early November. If you rush this on a damp afternoon and cover up wet furniture, you undo all the effort. Patience here is worth more than any premium cover.
3. Material-by-material care
Different materials fail in different ways, so winter prep is not one-size-fits-all. Here is how the common garden furniture materials behave and what each one needs before the cold sets in.
| Material | Main winter risk | Prep before storage |
|---|---|---|
| Teak & hardwood | Greying, surface splits | Clean, dry, apply teak oil or leave to silver naturally |
| Softwood (pine, acacia) | Rot, joint swelling | Oil or reseal; store under cover or indoors |
| Aluminium | Oxidation pitting, staining | Wash, dry, wax; keep off wet ground |
| Steel & wrought iron | Rust from chips in coating | Touch up paint chips; cover fully |
| Rattan (synthetic) | Brittle, cracking weave | Cover or store indoors; avoid frost flex |
| Plastic & resin | Brittleness, fading | Clean; store or cover to limit UV |
Teak and hardwoods are the most forgiving. Teak’s natural oils let it survive winter outdoors without a cover, weathering to a silvery grey. If you prefer the honey tone, apply teak oil in autumn and again in spring. Aluminium is rust-proof but not maintenance-free; a coat of car wax after cleaning seals the surface against pitting and water staining. Steel and wrought iron are the riskiest — any chip in the powder coating is a doorway for rust, so touch up bare spots with metal paint before covering. Our garden furniture buying guide goes deeper on choosing materials that suit your climate and how much upkeep you want.
Synthetic rattan woven over an aluminium frame is popular for a reason, but the PE weave can turn brittle in hard frost and crack if knocked. If you can move a rattan sofa set into a shed or garage, do — otherwise a breathable cover is essential.
4. Cushions, parasols and soft furnishings
Soft furnishings are the first thing to ruin and the most expensive to replace piecemeal, so they deserve special attention. Outdoor cushions are usually showerproof, not waterproof, and they are not designed to sit sodden for months. The rule is simple: cushions and textiles should never overwinter outdoors, even under a cover.
Bring every cushion, seat pad, scatter cushion and throw indoors. Store them somewhere dry and ventilated — a spare wardrobe, loft or under-bed box is ideal, a damp garage is not. Stand them on edge or in a breathable storage bag rather than stacking flat and airtight, which encourages mildew. If a cover is removable, wash it per the care label and make sure it is bone dry before packing.
Parasols need folding down, cleaning and thoroughly drying before storage, ideally in their sleeve and stored upright or flat off the floor. Never leave a parasol up over winter; even closed, wind can shred the canopy and snap the ribs. Outdoor rugs should be rolled and stored dry too — if you use garden outdoor rugs on a patio, lift them well before the first frosts.
5. Choosing and fitting weatherproof covers
A good cover is the workhorse of winter protection for anything staying outside. But the cheapest tarpaulin can be worse than nothing: if it traps condensation and can’t drain, you create a warm, wet micro-climate that grows mould faster than the open air. Look for these features:
- Breathable, waterproof fabric — quality covers use a coated polyester that sheds rain but lets water vapour escape, so condensation doesn’t build up underneath.
- A snug but not skin-tight fit — measure your set’s width, depth and height, and allow a little slack for airflow. A cover flapping loosely lets rain drive in; one stretched drum-tight traps damp.
- Air vents — mesh vents near the top let humid air out and stop the cover ballooning in wind.
- Tie-downs or a drawcord hem — to stop winter gales lifting it off. A cover in next-door’s garden protects nothing.
Fit covers over dry furniture only, and lift the whole set onto small feet, blocks or a couple of bricks so it sits above pooling water. For larger arrangements such as garden dining sets and garden sofas and chairs, stack or nest chairs where the design allows to reduce the covered footprint and cut down on wind resistance.
6. Indoor and outdoor storage options
If you have the space, moving furniture indoors is always the gold standard — no cover manages the elements as well as four dry walls. Ranked from best to most exposed, your realistic options are:
- Heated indoor space (garage, utility, conservatory): best of all for rattan, softwood and anything with fabric or fine finishes. Fold or stack to save room.
- Unheated shed or garage: excellent for most materials. Keep items off the concrete floor on battens or pallets, as cold slabs sweat with condensation.
- Sheltered outdoor spot plus cover: a porch, car port or wall recess out of the prevailing wind and rain. Cover on top.
- Open patio plus cover: the last resort, and fine for teak and quality aluminium, but demands the best breathable cover you can buy.
Folding and stacking designs earn their keep here — a bistro set that collapses flat tucks behind a shed door, while a fixed corner sofa needs a whole garage bay. If storage is tight, prioritise getting soft furnishings and any timber or steel pieces under a real roof, and leave the weather-hardy teak or aluminium outside under cover.
7. Drainage, airflow and freeze damage
This is the detail most people miss, and it is where furniture quietly dies over winter. Water that cannot drain away will freeze, expand and force joints apart. Tubular metal frames are especially vulnerable: rain runs down the inside of a hollow leg, collects at the bottom, freezes and splits the tube or blows out the welds. Check that leg caps and drainage holes are clear, and store tubular furniture tipped or upside down so water runs out rather than pooling.
Airflow is the twin priority. Damp trapped against a surface with no ventilation is what grows mould and rots timber, so never wrap furniture in cling-tight plastic. Even in a shed, leave a few centimetres between pieces and the wall. Raising everything 5–10cm off the ground on feet, blocks or a pallet keeps the base out of standing water and lets air circulate underneath.
Finally, resist the urge to chip ice off a frozen surface. Frozen finishes are brittle, and scraping gouges the coating that is protecting the metal or timber beneath. If a cover freezes stiff to the furniture, leave it until a milder day and let it release naturally. The same gentle-handling principle applies to your indoor pieces too, which is why our general guide on how to care for your furniture is worth a read.
8. Getting ready for spring
Winter protection is only half the job; how you bring furniture back into use matters just as much. On the first properly dry, mild days of spring — usually late March or April in most of the UK — uncover everything and give it a full inspection before you sit down.
Run through this checklist:
- Inspect for damage: check joints, welds, screws and the rattan weave for anything that has loosened or cracked over winter. Tighten bolts that have worked free.
- Clean off winter grime: a wash with warm soapy water lifts the film of algae and dust that builds up even under a cover.
- Re-treat surfaces: a fresh coat of teak oil, a wax on aluminium, or touch-up paint on any new rust spots restores protection for the season ahead.
- Air the cushions: bring soft furnishings back out on a dry day and let them air for a few hours before use to shake off any storage mustiness.
Spring is also the natural moment to assess whether anything is beyond saving and worth replacing. If a set has done its years, browsing the current ranges of garden furniture now, before the summer rush, usually means better choice and calmer delivery times than a July heatwave scramble.

Frequently asked questions
Can I leave garden furniture outside all winter?
Teak and quality aluminium can stay outdoors year-round if cleaned and covered, though teak will weather to grey. Steel, softwood, rattan and anything with cushions are much safer stored indoors or in a shed. Whatever you leave out should sit on feet above standing water and under a breathable cover.
Do I really need furniture covers, or is a tarpaulin enough?
A cheap non-breathable tarpaulin traps condensation and can grow more mould than leaving furniture uncovered. A purpose-made breathable, waterproof cover with air vents sheds rain while letting moisture escape, which is what you actually want. It’s a worthwhile upgrade over a basic sheet.
How do I stop metal garden furniture rusting over winter?
Clean and dry it fully, then touch up any chips in the paint or powder coating with metal paint before covering. A coat of car wax adds a protective barrier. Store tubular pieces tipped or upside down so water can’t collect and freeze inside hollow legs.
Where should I store outdoor cushions in winter?
Bring them indoors to a dry, ventilated spot such as a spare wardrobe, loft or under-bed box — never a damp garage. Store them on edge or in breathable bags rather than stacked airtight, and pop in a silica gel sachet to absorb moisture and prevent a musty smell.
Should I oil teak furniture before winter?
It’s optional. Teak survives winter without oil, weathering to a silvery grey many people like. If you prefer the warm honey tone, apply teak oil in autumn onto clean, dry wood and again in spring. Either way, always clean off dirt and sap before storing.
Why does condensation form under my furniture cover?
Usually because the cover is non-breathable or fitted too tightly over furniture that was damp when covered. Water vapour can’t escape, so it condenses underneath and encourages mould. Use a breathable cover with vents, fit it over bone-dry furniture, and raise the set off the ground for airflow.
Can frost really damage garden furniture?
Yes — the freeze-thaw cycle is a major cause of damage. Water seeps into wood grain, screw holes and hollow metal legs, then expands as it freezes, forcing joints and welds apart. The UK’s repeated wet-then-cold pattern is harder on furniture than a single hard frost.
When should I bring furniture back out in spring?
Wait for the first run of genuinely dry, mild days, typically late March or April. Uncover on a dry day, inspect joints and fixings, wash off winter grime, re-treat surfaces with oil or wax, and air the cushions for a few hours before using them.
