Gas Safe registered engineers (no. 665942) repairing leaking, corroded and damaged gas pipework in St Albans homes. We find the fault, make it safe, repair it and tightness test the whole installation before we leave.
Most gas pipe faults we see in St Albans fall into a few patterns: a weeping compression fitting behind a cooker that has been pulled out once too often, copper pipe that has corroded where it runs through a damp floor void or an outside wall, steel pipework in older Victorian and Edwardian houses rusting at the threads, and pipes nicked by a screw or nail during kitchen or flooring work.
Every job starts with a tightness test at the gas meter. A gauge on the test point shows whether the installation is losing gas and how quickly, before we look for the exact spot. We then trace the leak with an electronic gas detector and leak detection fluid on the joints and fittings. If you would like the leak found first and quoted separately, that is our gas leak detection service.
Once we know the cause, we explain the options and agree the price before any work starts. A single failed fitting can usually be remade or replaced on the same visit. Where a run of pipe is corroded or was badly installed, replacing that section is often safer, and cheaper in the long run, than patching it. After the repair we tightness test the full installation again, purge the air out of the pipework, relight and check every appliance on the supply, and give you a written record of the test.
If the pipe feeds a cooker or hob, we can reconnect it with a new bayonet fitting and hose as part of the job, or fit a replacement through our gas appliance installation service. Where the fault is inside the boiler rather than the pipe feeding it, our boiler repair engineers take over. Landlords who need the work signed off can book it alongside a gas safety inspection.
Gas pipework rarely fails without a reason. Knowing the common causes helps you spot a problem early, and it is exactly what we look at when we arrive.
These are the signs that usually lead to a call to us. If you can smell gas, treat it as an emergency first and call the National Gas Emergency Service on 0800 111 999.
A smell of gas near the meter, a cooker or along a pipe run means gas is escaping. Turn off the supply at the meter, open windows and call 0800 111 999 first.
Green or white crusting on copper, rust on steel pipe, kinks, dents or a pipe that has been knocked loose all need checking by a Gas Safe engineer.
A hiss from a pipe or fitting with every appliance turned off is a sign of a leak under pressure. Leave the area and call the emergency number.
A hob flame that lifts or shrinks, or a boiler that cuts out when the cooker is on, often points to a restricted or undersized pipe rather than a faulty appliance.
From a single leaking joint to replacing a corroded run of pipe, every repair finishes with a tightness test and a written record, so you know the installation is safe to use.

The most common signs are a smell of gas near the meter, pipework or an appliance, a hissing sound from a pipe, visible corrosion or damage, and a hob flame that is weak or uneven. A failed tightness test during a boiler service or gas safety check is another common way leaks are found.
Yes. We find the exact leak, then remake or replace the failed fitting or section of pipe. Before we leave, the whole installation is tightness tested and purged, and every appliance is relit and checked.
We start with a tightness test at the meter, which shows whether gas is escaping and how fast. Then we trace it with an electronic gas detector and leak detection fluid on the joints. Pipes hidden under floors or in walls may need a floorboard lifted or a small opening made, which we always agree with you first.
Yes. If a section of pipe is corroded, damaged in several places or was installed incorrectly, replacing it is usually the safer option and often costs less than repeated repairs. We explain why and give you the price before starting.
The gas has to be off while we work, so appliances on that supply will be off for the duration. Afterwards we purge the pipework, relight the boiler, cooker and hob, and check each one is burning correctly.
Yes. If you smell gas, turn off the supply at the meter if you can do so safely, open doors and windows, do not use flames or electrical switches, leave the property and call the National Gas Emergency Service on 0800 111 999. Once they have made the supply safe, call us to carry out the repair.
