Burst Pipe in Glasgow: What to Do Right Now

Step 1: Turn Off the Water Supply Immediately

The most important thing you can do is isolate the water supply as fast as possible. Find your stopcock — the main isolation valve — and turn it clockwise until it will not move. This stops water flowing into your property.

Where to find your stopcock in Glasgow

• Flat or tenement: Most commonly under the kitchen sink. In older Glasgow tenements, there may be a shared stopcock in the close stairwell or a communal meter cupboard — you may need to speak with your factor or a neighbour.
• Terraced or semi-detached house: Usually under the kitchen sink, in the utility room, or beneath a floorboard near the front of the property.
• Cannot find it? There is a stopcock at the boundary of almost every Glasgow property, typically under a small cover in the pavement or front path. You may need a long-handled key to operate it. If you have no key and cannot isolate the supply, call Scottish Water on 0800 077 8778 — they operate 24/7.

Step 2: Drain the System

Once the stopcock is off, open all the cold taps in the property. This drains any water still sitting in the pipes above the fault and reduces the pressure causing the leak. Flush the toilets once to empty the cisterns.

Do not open the hot taps yet — wait until you have turned off the boiler (see step 3).

Step 3: Turn Off Your Boiler and Water Heater

Switch off your boiler and any immersion heater or hot water cylinder immediately. Running a boiler without adequate water pressure can cause permanent damage to the heat exchanger. Once the boiler is off, you can open the hot taps to drain the hot water circuits too.

Step 4: Protect Your Electrics

Water and electricity are a dangerous combination. If water is leaking near any light fittings, sockets, switches or the consumer unit, switch off the electricity at the main switch in your consumer unit before doing anything else. Do not touch any electrical fitting that has come into contact with water.

If the consumer unit itself is affected, call an emergency electrician as well as a plumber. FixNow Glasgow handles both — call 07719 557314 and we will send the right team.

Step 5: Limit the Water Damage

While you wait for the plumber, take steps to reduce the spread of water:

• Move furniture, rugs, and valuables away from the affected area. Water spreads quickly under flooring and into adjacent rooms.
• Use towels, bowls or buckets to contain pooling water. If ceiling plaster is bulging with water, pierce it in one controlled spot with a screwdriver to release it into a bucket — otherwise it may collapse without warning.
• Take photographs and video of all damage for your insurance claim. Capture the source of the leak, affected areas, and any damaged belongings.
• Call your home insurer if the damage is significant. Most emergency plumbing from a sudden burst is covered; your insurer may also arrange drying equipment.

Step 6: Call an Emergency Plumber in Glasgow

Once the water is off and the immediate situation is under control, call a 24/7 emergency plumber. FixNow Glasgow aims to reach all Glasgow postcodes within 1 hour. Call us any time on 07719 557314.

When you call, tell the plumber:

• Whether you have successfully isolated the water supply
• Whether there is any risk to electrics
• The property type (flat, tenement, house) and access arrangements

Common Causes of Burst Pipes in Glasgow Properties

Understanding what caused the burst helps your plumber arrive prepared with the right parts and tools.

• Frozen pipes: The most common cause of sudden bursts in Glasgow during cold snaps. When water freezes inside a pipe, it expands and splits the metal or plastic. Loft pipes and pipes in unheated spaces are most vulnerable.
• Corrosion: Older Glasgow properties — particularly tenements built before the 1970s — sometimes still have original copper or lead pipes that have corroded through over decades.
• High water pressure: Excessive mains pressure can stress joints and fittings to the point of failure, particularly in older installations.
• Accidental damage: DIY drilling, building work, or rodent damage can puncture or crack pipes behind walls or under floors.
• Failed joints or fittings: Push-fit or compression fittings that have worked loose over time can fail suddenly, especially on older waste pipes under sinks and baths.

How Much Does Burst Pipe Repair Cost in Glasgow?

The cost to repair a burst pipe in Glasgow depends on where the pipe is and how much access is needed. For a straightforward accessible pipe, expect to pay £100–£200. If the pipe is inside a wall or under a floor and requires chasing out or lifting boards, costs rise to £200–£400 or more.

Emergency out-of-hours rates apply at evenings, weekends and bank holidays. For a full breakdown of plumbing costs in Glasgow, see our plumber price guide.

Will Insurance Cover a Burst Pipe in Glasgow?

Most standard home insurance policies in the UK cover sudden and accidental escape of water — which includes burst pipes. Your policy will typically cover:

• The cost of repairing or replacing the burst pipe itself
• Water damage to floors, walls, ceilings and internal decorations
• Damage to furniture and belongings in the affected rooms
• Drying-out costs (dehumidifiers, fans)

What is typically not covered: gradual leaks or seepage that should have been identified and repaired earlier, or damage caused by lack of maintenance. Always check your policy excess before claiming, as emergency plumbing costs often fall below a standard £250–£500 excess.

Photograph everything before the plumber repairs the fault — insurers require evidence of both the source of the damage and the resulting damage.

Preventing Burst Pipes in Glasgow: Key Tips

• Insulate exposed pipes in cold spaces. Loft pipes, pipes in garages, and pipes against external walls are most at risk during Glasgow winters. Foam lagging costs very little and prevents the most common type of burst.
• Know where your stopcock is before an emergency. Check it once a year — stopcocks that have not been turned for years can seize in the open position, making them useless in an emergency.
• Keep the heating on low when away in winter. Even a frost setting (7–10°C) keeps internal temperatures above freezing and prevents pipes from splitting in unoccupied properties.
• Have older pipework inspected. If your Glasgow property was built before 1980, a plumbing survey can identify corroded or vulnerable pipes before they fail.
