“Frozen pipes don’t just mean temporary inconvenience—they can lead to serious water damage and expensive emergency repairs. Winterising your system is a simple investment in long-term peace of mind.”
Why Winterising Your Plumbing System Matters
As temperatures fall, so does the efficiency and reliability of your plumbing system. Water expands as it freezes, exerting intense pressure on the pipes—especially those in unheated areas, such as lofts, garages, and external walls. If not addressed early, the result can be costly bursts and significant water damage.
Whether you live in a period property or a new build, taking steps to prepare your winter plumbing in Wandsworth can help you avoid emergencies, protect your home, and reduce energy bills.
What Are The Signs Your Plumbing Needs Winterisation?
1. Uninsulated Pipes In Cold Spaces
Pipes located in garages, lofts, under kitchen sinks, or near external walls are most vulnerable. If these pipes lack proper insulation, they are at high risk of freezing during cold snaps.
2. Persistent Leaks Or Drips
Even minor leaks can worsen in winter. Water can freeze in or around the pipe, blocking the flow or causing cracks. Resolve leaks before cold weather intensifies the issue.
3. Irregular Heating Or Water Pressure Drops
Sudden drops in water pressure or inconsistent heating may signal a developing freeze within the plumbing. It’s best to address these issues early with help from a qualified emergency plumber in Wandsworth.
How To Winterise Your Plumbing System Effectively
1. Insulate Exposed Pipework
Use foam lagging, pipe sleeves, or fibreglass to wrap exposed pipes. Pay special attention to areas where pipes run along external walls or through unheated rooms. Adequate insulation is one of the best defences against freezing.
2. Disconnect And Drain Garden Hoses
Outdoor taps and garden hoses should be turned off at the isolation valve, drained, and insulated with a proper cover. Leaving water in these pipes could result in a block and pipe split.
3. Seal All Entry Points And Gaps
Cold air seeping through unsealed pipe entries can cause water inside to freeze. Use silicone seals around pipe entry points in walls and floorboards to keep warm air in and the cold out.
4. Fit A Pressure Reducing Valve
In colder months, frozen water can lead to a pressure build-up. Installing a pressure-reducing valve helps balance your system and minimises the risk of bursting under strain.
5. Bleed Radiators Regularly
Trapped air reduces radiator efficiency and affects central heating performance. Bleeding your radiators ensures consistent warmth and helps prevent freezing in heating pipes.
6. Book A Winter Health Check
A professional plumbing service in Wandsworth can inspect your entire system, identify weak spots, and provide preventative solutions tailored to your home.
Additional Frozen Pipe Prevention Tips
1. Maintain A Low, Steady Heat
Even if you’re away for a few days, keep the thermostat set between 12°C–15°C. This prevents internal plumbing from freezing while conserving energy.
2. Open Kitchen And Bathroom Cupboards
This allows warm air to reach pipes behind cupboards and under sinks—an easy step that can prevent frozen pipes overnight.
3. Install Leak Detectors Or Smart Valves
Smart devices can detect drops in temperature or moisture and alert you early. These are ideal for second homes or properties that are left unoccupied during the winter.

FAQs
1. How do I know if my pipes are at risk of freezing?
Pipes in unheated or poorly insulated spaces, such as garages, external walls, and lofts, are most at risk. If you’ve experienced freezing before or notice low flow during cold spells, take action.
2. Can I insulate my pipes myself?
Yes, many insulation products are suitable for DIY use. However, for hard-to-reach areas or comprehensive system checks, a professional plumber can ensure that nothing is missed.
3. What should I do if I suspect a frozen pipe?
Turn off your water supply immediately and call an emergency plumber. Trying to thaw a pipe yourself can sometimes cause more harm than good.
4. How often should I check my system in winter?
We recommend a quick visual check weekly, especially during cold snaps. A full winter check from a qualified professional should be done annually.
