To insulate your water pipes and prevent frozen pipes<\/a>, fit foam pipe sleeves or lagging around exposed pipework in lofts, garages, and under sinks, sealing every joint and bend with insulation tape. Focus on pipes in unheated spaces first, keep a trickle of heat in the house during cold snaps, and know where your stopcock is in case anything goes wrong.<\/p>\n\n\n\n

There’s a particular kind of dread that comes with waking up on a freezing January morning, turning on the kitchen tap, and getting… nothing. If you’ve been there, you’ll know that a frozen pipe is annoying at best and a hefty repair bill at worst. <\/p>\n\n\n\n

The good news? Insulating your water pipes is one of the cheapest, easiest jobs you can do this autumn, and you don’t need to be a plumber to get it right. In this guide, we’ll walk you through exactly how to insulate your water pipes, which materials work best, and what to do if you’re already too late and staring at a frozen tap.

Water expands as it freezes. When it’s trapped inside a pipe with nowhere to go, that expansion puts serious pressure on the pipe walls, and something eventually gives. The pipe splits, and the second the ice thaws, water starts pouring out, often inside a wall or ceiling where you won’t notice until it’s too late.<\/p>\n\n\n\n

The pipes most at risk are the ones exposed to cold air: those in lofts, garages, under-sink cupboards, and anywhere near an external wall. If a pipe run passes through an unheated space at any point along its length, it’s vulnerable, even if the rest of the run is snug and warm.<\/p>\n\n\n\n
