Why Coastal Homes Face a Harder Winter

Living by the sea is a privilege, but the winter months ask more of a coastal property than an inland one. Salt-laden air, exposure to the full force of prevailing south-westerlies and the sheer volume of wind-driven rain mean that small maintenance oversights can turn into expensive repairs by February. Add the likelihood of power cuts when overhead lines come down, and it pays to spend a few crisp autumn afternoons getting ahead of the weather.

The good news is that most of what protects a coastal home is straightforward, inexpensive and well within the reach of any reasonably practical owner. Here is a sensible order of priorities.

Clear the Water Before It Finds Its Own Way

Wind-driven rain rarely falls straight down, so water arrives on walls and windows rather than neatly into gullies. Your first job is to give it every possible route away from the building.

• Clear gutters, hopper heads and downpipes of moss, leaves and grit. A blocked downpipe in a storm sends water down the wall and into the cavity.
• Check the fall on gutters and repair any sagging brackets — a shallow section will overflow in a heavy burst.
• Lift drain covers and rod the gullies before the first storm. If water stands in a gully for more than a minute or two, it is already partly blocked.
• Consider a channel drain across the driveway threshold, or a French drain along the windward side of the house if you regularly get standing water.
• Fit non-return valves to any ground-floor drainage that has backed up before, and keep air bricks clear but covered with purpose-made shields.

If your property has flooded in the past, buy sandbags or a reusable flood barrier now, not when a warning is issued. Stocks sell out within hours.

Windows, Doors and the Battle Against Wind-Driven Rain

Water is remarkably good at finding joints. On an exposed elevation, a storm at 50 or 60mph will push rain past seals that look perfectly sound in calm weather.

• Rake out and renew silicone around frames, sills and thresholds, and check that external sills slope away from the wall.
• Test every opening window before winter. Replace perished gaskets and draught strips, and adjust espagnolette handles so the frame pulls tight.
• Check drip bars and weatherbars on outward-opening doors, and make sure the threshold does not sit below the external paving.
• Secure loose fittings — house numbers, satellite dishes, hanging baskets and porch canopies all become projectiles.

Sash windows in older seaside properties benefit from a simple wedge or sash stay to stop them rattling in a gale, plus a smear of water-displacing spray on the pulleys each autumn.

Protect the Fabric of the Building from Salt and Wind

Salt spray accelerates corrosion and slowly eats away at render and pointing. A short inspection in October saves scaffolding bills later.

• Look at ridge tiles, flashing and chimney pots from ground level with binoculars. Anything cracked or visibly lifted needs attention before the first gale.
• Repoint eroded mortar on the seaward wall, and treat hairline render cracks with an exterior filler.
• Grease external hinges, locks and gate latches with a marine-grade product — salty air will seize them solid otherwise.
• Tie down or store garden furniture, trampolines, bins and planters. Fence panels are the classic casualty; a brace across the back of each one helps.
• Prune overhanging branches well clear of the roof and overhead cables, and cut back any shrubbery touching the walls.

Power Cuts: Plan for the Lights Going Out

Overhead supplies on exposed coastlines are vulnerable, and a cut can last hours rather than minutes. Prepare as though it will happen, because one winter it probably will.

• Build a simple kit: two torches and a head torch, spare batteries, a battery or wind-up radio, a power bank kept fully charged, and a first aid kit in a known drawer.
• Keep a printed list of emergency numbers and know the national power cut line — 105 — as well as the gas emergency number.
• Locate your stopcock, fuse board and gas isolation valve now, and label them. Know how to reset an RCD.
• Think about heating and cooking. A gas hob can often be lit with a match; a hot water bottle and extra blankets matter more than you would expect in a cold snap.
• Keep the freezer shut. A full freezer holds its temperature for around 24 hours if the door stays closed.

If anyone in the household relies on electrical medical equipment, register with your network operator's priority services list in advance.

Insurance, Records and Looking Out for Neighbours

Photograph every room and any valuable items, and store the images in the cloud rather than on a device that could be damaged. Read your policy's storm and flood definitions carefully, and check the excess — coastal postcodes sometimes carry a higher one. Keep documents and irreplaceables in a sealed box above floor level.

Finally, coastal communities look after their own. Swap mobile numbers with the neighbours either side, agree who will check on anyone elderly or living alone, and share out spare torches and sandbags. A street that plans together comes through a storm far better than one that does not.
