Preparing Your Home for Winter in the Cotswolds

Winter in the Cotswolds is not the hardest in the country, but it is often damp, windy, and prone to sharp frost nights in January and February. Stone cottages, older extensions, and rural properties all have particular weaknesses. This guide walks through what to check before the clocks change, and what to do when they do.

Gutters and downpipes

Gutters fill with leaves every autumn, but in the Cotswolds they also fill with moss washing off stone tiles and slate roofs. A blocked gutter does two things. First, it overflows during heavy rain, sending water down the outside wall, which soaks into the stone and causes damp patches inside. Second, in a sharp frost, it holds standing water which freezes, expands, and cracks the gutter or the downpipe joint.

Clearing gutters once a year, usually in late October or early November after most of the leaves have fallen, is enough for most homes. Semi-detached houses in the town can usually be done from a ladder; larger detached properties in the villages may need scaffolding or a gutter vacuum. A typical gutter clear on a semi costs around £75 to £95 including disposal.

Draught-proofing

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

Door draught strips come in two types: compression seals (for the top and sides of a door) and brush seals (for the bottom). Both are cheap and can be fitted in under an hour per door. Keyhole covers, letterbox brushes, and a heavy curtain over the front door all help further.

Windows are more complex. Sash windows can be draught-proofed without losing their character; casement windows usually take a rubber seal along the frame. Secondary glazing panels fitted inside the existing window work well in listed buildings where replacement is not allowed.

Lagging exposed pipes

This is the single most important winter job in an older Cotswold house, and the most commonly skipped. Pipes that run through unheated roof spaces, garages, outbuildings, or against exterior walls will freeze in a cold snap. A frozen pipe bursts when it thaws, not when it freezes, and the burst is often not discovered until water is running down a ceiling.

Foam pipe lagging is cheap, around £2 to £4 per metre, and fits over pipes in minutes. Pay particular attention to the cold water tank in the loft, the pipes running to and from it, and any pipes in a cellar or basement. An outside tap should have its supply pipe lagged and the tap itself covered in winter, or ideally isolated and drained down for the season.

Bleeding radiators

A radiator with air trapped inside does not heat properly at the top. Over the summer months, air tends to collect in the system, and by October each radiator in the house is often running at less than full efficiency. Bleeding them takes five minutes per radiator and a bleed key (usually 50p from a hardware shop).

Turn the heating off, wait for the radiators to cool, put the key in the small valve at the top corner, and turn it slowly anticlockwise until water comes out instead of air. Close the valve, move on. Check the boiler pressure afterwards and top it up if needed, usually back to around 1.2 to 1.5 bar.

Smoke alarm batteries

The clocks going back is the traditional reminder to test smoke alarms and replace batteries. This is still worth doing. Every alarm in the house should be tested by pressing the button, including carbon monoxide alarms and heat alarms in the kitchen. Alarms older than 10 years should be replaced regardless of whether they still beep; the sensor degrades over time and may not trigger even when the test button still works.

Chimneys and wood burners

If the house has an open fire or a wood burner, the chimney should be swept before the season starts. A chimney sweep typically charges £60 to £90. A blocked or dirty chimney is a fire risk and also a carbon monoxide risk if gases back up into the room. Anyone with a wood burner should have a working carbon monoxide alarm in the same room.

Key safe access for emergencies

Winter is when paramedics, carers, and family members most often need to get into a house quickly. A police-approved key safe fitted to an external wall, with the code shared with immediate family and any regular carer, takes the stress out of an emergency. Fitting a key safe costs around £50 plus the unit itself (£60 to £90 for a police approved model like the Supra C500). It is covered in more depth in the keysafe guide.

Salt and paths

A bucket of rock salt or grit kept by the back door from early November is one of the simplest winter preparations possible. Spread on the path before freezing weather, it prevents ice forming; spread after, it melts it. A 25kg bag of rock salt costs around £8 and lasts most households a full winter. For older residents, a family member or neighbour agreeing to grit the path before a forecast cold night is one of the most useful practical kindnesses going.

Specific Cotswold stone issues

Stone houses have a few quirks that modern advice often misses.

• Pointing. Old lime mortar is softer than the stone around it. This is deliberate; it allows the wall to move without cracking the stone. Modern cement repairs trap moisture and cause damage. If pointing is crumbling, it should be replaced with lime mortar by someone who knows what they are doing, not patched with cement.
• Breathability. Stone walls need to release moisture to the inside and outside air. Blocking this with plastic paint on the outside or vinyl wallpaper on the inside causes damp and staining. Breathable paint (lime-based or clay-based) works best.
• 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) help.
• Window reveals. Deep stone window reveals create thermal bridges. Heavy curtains, shutters, or thermal blinds reduce heat loss in winter significantly.

The bottom line

A half-day of work in late October covers most of the essentials: gutters cleared, draughts sealed, pipes lagged, radiators bled, alarms tested, salt by the door. Add a chimney sweep if there is a fire, and a key safe if there is an older resident. Cotswold stone houses need a bit more care than newer builds, but the principles are the same. The list is short, cheap, and worth doing.
