Preparing your home for winter in the Cotswolds

Cotswold winters are not the coldest in England, but they are damp, they are windy, and the frost nights in January and February catch people out every year. Stone cottages, older extensions, and rural properties all have weak points that modern maintenance guides tend to miss. This is what to check before the clocks go back, and what to deal with once they have.

Gutters and downpipes

Gutters fill with leaves every autumn. In the Cotswolds they also fill with moss washing off stone tiles and slate roofs, which forms a thick plug that water cannot pass through.

A blocked gutter overflows during heavy rain, sending water down the outside wall. The stone soaks it up. Damp patches appear inside. Then in a sharp frost, the standing water left in the gutter freezes, expands, and cracks the joint where the downpipe meets the hopper. Two problems for the price of one.

Clearing gutters once a year in late October or early November, after most leaves have fallen, is enough for most homes. A semi-detached in town can usually be done from a ladder. Larger detached properties in the villages may need scaffolding or a gutter vacuum. Typical cost on a semi: £75 to £95 including disposal.

Draught-proofing

Old Cotswold houses leak air. That is not always a problem; stone walls need to breathe, and sealing them too tightly causes condensation. But the obvious gaps around doors, windows, and loft hatches are worth closing.

Door draught strips come in two types: compression seals for the top and sides, and brush seals for the bottom. Both are cheap and go on in under an hour per door. Keyhole covers, letterbox brushes, and a heavy curtain behind the front door all help.

Windows are trickier. Sash windows can be draught-proofed without losing their character. Casement windows usually take a rubber seal along the frame. In listed buildings where replacement glazing is not permitted, secondary glazing panels fitted inside the existing window are often the best option.

Lagging exposed pipes

This is the single most important winter job in an older Cotswold house. It is also the one most commonly skipped.

Pipes running through unheated roof spaces, garages, outbuildings, or along exterior walls will freeze in a cold snap. The burst happens when they thaw, not when they freeze, and it is often not discovered until water is running down a ceiling. Foam pipe lagging costs £2 to £4 per metre and fits over pipes in minutes. Concentrate on the cold water tank in the loft, the pipes running to and from it, and anything in a cellar or basement. An outside tap should be lagged and ideally isolated and drained down for the season entirely.

Bleeding radiators

A radiator with trapped air does not heat properly at the top. Over the summer months, air collects in the system, and by October many radiators are running well below full capacity.

Bleeding takes five minutes per radiator and a bleed key (about 50p from any hardware shop). Turn the heating off, let the radiators cool, put the key in the small valve at the top corner, turn slowly anticlockwise until water comes out instead of air. Close the valve. Move on. Check boiler pressure afterwards and top it up to around 1.2 to 1.5 bar if it has dropped.

Smoke alarm batteries

The clocks going back is the traditional reminder. Test every alarm by pressing the button: smoke alarms, carbon monoxide alarms, heat alarms in the kitchen. Replace batteries in any non-sealed unit. Any alarm older than 10 years should be replaced outright, even if it still beeps when tested. The sensor degrades over time and may not trigger properly when it matters.

Chimneys and wood burners

If the house has an open fire or a wood burner, get the chimney swept before the season starts. A sweep typically charges £60 to £90. A dirty chimney is both a fire risk and a carbon monoxide risk if gases cannot escape properly. Anyone with a wood burner should have a working carbon monoxide alarm in the same room.

Smoke alarms and CO detectors for winter

Winter is when heating runs hardest, fires get lit, and carbon monoxide risks increase. Smoke alarms and CO detectors need working batteries. Martin checks every alarm in the house, replaces any flat batteries, and tests them before leaving. It takes fifteen minutes and costs nothing beyond the visit time.

Salt and paths

A bucket of rock salt by the back door from early November. Spread it on the path before freezing weather to stop ice forming; spread it after to melt what has already formed. A 25kg bag costs around £8 and lasts most households the full winter. For older residents, a family member or neighbour who grits the path before a forecast cold night is one of the most practically useful things anyone can do.

Cotswold stone: specific problems

Stone houses have quirks that standard advice misses.

• Pointing. Old lime mortar is deliberately softer than the stone around it. This lets the wall flex without cracking the stone. Patching it with modern cement traps moisture and causes damage over time. If pointing is crumbling, it needs replacing with lime mortar by someone who understands the difference.
• Breathability. Stone walls release moisture to the inside and outside air. Blocking that process with plastic paint on the outside or vinyl wallpaper on the inside causes damp and staining. Breathable finishes (lime-based or clay-based paint) work properly with the wall instead of against it.
• Cold spots. Solid stone walls are colder than cavity walls and often show condensation or black mould in the corner of a north-facing room. Better ventilation, a small amount of background heating, and internal insulation where feasible all help.
• Window reveals. Deep stone reveals create thermal bridges. Heavy curtains, shutters, or thermal blinds cut heat loss significantly in winter.

A half-day in late October covers most of this: gutters cleared, draughts sealed, pipes lagged, radiators bled, alarms tested, salt by the door. Add a chimney sweep if there is a fire, and alarm batteries checked throughout the house. The list is short, the cost is low, and putting it off until December rarely ends well.
