The stopcock is off, the flow has stopped, and now you’re stood there looking at a damp patch, a wet floor, or a ceiling that’s taken the worst of it. First thought: thank goodness. Second thought, about thirty seconds later: right, what now?
Here’s the honest answer. Fixing the pipe is the easy bit. The part that catches people out is everything around it, the stuff that got wet, the drying out, the question of who pays for what. We’ve been into plenty of homes in Aldershot a week or two after a burst, where the pipe itself was sorted but the wall behind it was still holding water like a sponge.
So this is the guide we wish more people had before they patched, plastered and painted too early.
First, make sure the situation is safe
If water is actively pouring through the ceiling as you read this, isolate the water at the stopcock first. If water is anywhere near electrics, switch off the power at the consumer unit, but only if you can reach it safely. Then get a plumber out who can come fastest, whoever that may be.
We want to be clear: Heat Eco doesn’t offer an emergency call-out service. If there’s an active leak, please don’t wait for a booked site visit with us. Your first priority is stopping the water and getting someone to the property who can deal with it.
Once the water’s under control, take a breath. And before you bin anything or start repairs, hold on a moment, there are a few things worth doing first that make the whole job easier later.
Photograph the damage before drying starts
Take photos and videos of everything: the split pipe if you can see it, the path the water took, wet walls and ceilings, affected floors, belongings that got soaked. Do it before anything gets ripped out or drying kit goes in, if it’s safe to. Jot down when you found the leak and when you turned the water off. It feels a bit morbid photographing the wreckage of your own hallway, but your future self will thank you.
Get in touch with your insurer or home-emergency provider promptly and ask what they need you to do before permanent repairs or reinstatement. Cover varies between policies. Some may cover resulting damage to the building or belongings, while repairing the failed pipe itself may be treated differently. Keep invoices and records, and ask before discarding the failed pipe or damaged items.
For practical guidance on what to do when a pipe bursts, see WaterSafe’s advice. Their guide to plumbing repairs and water damage is also useful when checking what to ask your insurer.
What does a proper split pipe repair involve?
For a straightforward repair, we don’t wrap the damaged spot with tape and hope for the best, that’s a leak waiting to happen again in the next cold snap. We find the affected section, open up proper access, cut out the split length and fit a new section of matching pipe and fittings. A new length of pipe with sound joints either side beats any bodge you can put over a crack.
That means some dust and disruption if the pipe is behind plasterboard, under flooring or boxed in. The opening needs to be large enough to work safely and check the pipe around the break. A split can leave nearby pipework strained or damaged too, so we look beyond the obvious crack before closing anything up.
After fitting the replacement section, the plumbing is refilled and checked for leaks. We then pressure-test the repaired pipework and confirm it is holding before the access area is made good. If the damaged pipe is part of a heating system, the repair may require draining and refilling the relevant circuit, rather than simply restoring the household water supply.
Why draining down properly matters
Turning off the stopcock stops the incoming supply, but there can still be water sitting in the pipework. Opening taps can help release pressure and drain water from the lines. Depending on where the split is and what system it serves, the plumber may need to drain the affected section or more of the system before cutting and fitting the new pipe.
This isn’t just about making our own job easier. Water left sitting in the line escapes the moment you cut into it, usually onto exactly the thing you’re trying to protect. And a repair can’t honestly be signed off until the system’s been refilled and pressure tested. We’ve lost count of the times a refill has shown us something the first look didn’t, a weeping joint, a second split further along, the sort of thing you want to find with the floor up rather than a month later.
The pipe is fixed. The wall may not be.
This is the part that can take longer than people expect. Water can travel along pipework, joists and the back of a wall, then soak into plaster, flooring, timber or insulation. A surface may feel nearly dry while moisture is still held inside the materials.
A leak-soaked wall or floor often takes weeks, not days, to dry. The time varies with how much water escaped, how long it ran, the materials involved, ventilation and the conditions in the property. Wet insulation can be especially tricky because it may hold moisture out of sight. It needs assessing rather than simply assuming it is dry or automatically removing it.
Moisture readings and follow-up checks help establish whether the area is ready for repairs. Depending on the extent of the damage, controlled ventilation, dehumidifiers or specialist drying may be needed. Don’t rush to plaster, paint, relay flooring or seal a wall just because the surface looks dry. Doing so can trap moisture and leave the underlying structure damp.
The hidden mould risk: moisture sealed behind finishes
Small pockets of moisture hang around inside a wall or floor long after the visible leak has stopped. Close a damp area up too soon and that moisture has nowhere to go, it just sits there behind your lovely new plaster. Give it time and you get mould, a musty smell that never quite goes away, and damage creeping through plaster, timber or insulation. We’ve opened up walls that were repainted twice before anyone found what was hiding behind them.
That’s why drying is not just about making the room comfortable again. It’s about allowing the construction to dry through before new finishes hide the evidence. If a wall or floor needs opening up, try to agree the scope with your insurer before reinstatement where practical, and keep records of any moisture checks and drying work.
What might a straightforward repair cost?
As a broad indicative range, not a quote, a simple, accessible burst-pipe repair involving cutting out the split section, fitting a new length, refilling and pressure-testing may be around £150–£350. The actual cost depends on access, pipe type, the extent of damage and what needs draining.
That figure doesn’t cover drying out, new plaster, flooring, decorating or any of the making-good. And here’s the thing to watch for: a quote that doesn’t say what’s included is a quote that grows. A proper one itemises the whole scope, the access, the pipe, the refill, the test, so you can see what you’re actually paying for. If the pipe is buried or the damage turns out worse once we open things up, the scope can change, and we’ll say so before we carry on rather than after.
Getting from leak to finished repair
The order matters more than the speed: stop the water, photograph the damage, talk to your insurer, repair and test the pipe, then let everything dry properly before closing it up. It’s not a tidy process and we won’t pretend otherwise, for a while there’ll be a hole in the wall or a lifted patch of floor and the room won’t look its best.
But handled in the right order, the result is more than a stopped leak. It’s a properly replaced pipe, tested plumbing and a better chance of avoiding hidden damp behind a fresh finish.
