Recommend very highly!Posted on Google Serena ReidTrustindex verifies that the original source of the review is Google. Came home from on holiday on 03/01/26 to the boiler not working - not heating or hot water - on one the coldest days of the winter. Was calling round desperately to find emergency plumber at 8pm on a Saturday. Despite calling multiple plumbers, none could come until the Monday...Then there was Alex! He came round on that Saturday night, found the problem and made a plan to replace the broken part. He was AMAZING! He was upfront about costs, timings, issues and part sourcing. Within 72 hours (part sourcing and error code issues that, were unrelated to Alex, were an issue) We had our boiler back working. Very grateful to Alex, who was so in demand and worked like trooper, would 100% recommend himPosted on Google Jasmine KershawTrustindex verifies that the original source of the review is Google. Can’t recommend highly enough! Alex arrived quickly and fixed our leaking water heater in a jiffy. He gave some great, honest advice and charged exactly what he said he would (a very good price). Efficient and friendly - will definitely be saving his number for future plumbing crises.Posted on Google Leo JasminTrustindex verifies that the original source of the review is Google. Alex sorted out all the problem in my boiler, great service and friendly, highly recommended for boiler and heating problems👍
Plumbing Repairs
Frequently Asked Questions
What plumbing faults do you repair?
We repair domestic water-supply and waste-system faults, including leaking pipework, taps, toilets, valves, traps and damaged fittings. If the visible symptom may come from a concealed source, we may recommend a separate hidden-leak assessment.
What are the most common plumbing repairs?
Common jobs include:
- repairing leaking pipes, joints and valves;
- fixing dripping taps and faulty toilets;
- replacing damaged traps, wastes and fittings;
- investigating low water pressure;
- repairing burst or frozen pipe damage once the area is safe.
Blocked drains are handled through our dedicated drain unblocking service.
How do I know if I need a plumbing repair?
Warning signs include persistent drips, damp patches, water stains, a toilet that keeps running, poor pressure, unusual pipe noise or an unexplained rise in water use. Early assessment can limit water damage and help identify whether a repair or further inspection is appropriate.
Which plumbing repairs are safe to do myself?
You can safely tighten a loose tap handle or clear an accessible trap only if you understand the fitting and have isolated the water. Do not dismantle pressurised, concealed or gas-related systems. For active leaks, isolate the water if safe and call a plumber.
How much does a plumbing repair cost?
Cost depends on the fault, access, time and parts required. We assess the problem, explain the recommended scope and provide an estimate before agreed work begins. If investigation reveals a different fault, we discuss it before carrying out additional work.
How long does a plumbing repair take?
Many tap, toilet and accessible pipe repairs can be completed during one visit. Concealed leaks, damaged pipe runs or faults requiring specialist parts may take longer. After diagnosis, we explain the expected work and timing for your specific repair.
What should I do if I notice a water leak?
If water is escaping:
- turn off the nearest isolation valve or main stopcock if it is safe;
- keep water away from electrical fittings and do not touch wet electrics;
- use towels or a container only if this is safe;
- call our 24/7 emergency plumber.
We aim to attend within the hour, subject to location, traffic and engineer availability.
Are plumbing repairs covered by home insurance?
Cover depends on your policy, the cause of the fault and whether damage was sudden or developed over time. Contact your insurer and keep photographs, invoices and the plumber’s findings. We cannot confirm coverage on behalf of an insurer.
How can I reduce future plumbing problems?
Act on drips and pressure changes early, know where your stopcock is, avoid flushing wipes or unsuitable items, protect vulnerable pipes in cold weather and arrange an inspection when symptoms keep returning. Our plumbing inspection service can help assess recurring concerns.
