Gas Leak Detection & Emergency Repair in North East Lincolnshire
Gas Safe Registered Engineers (No. 932713) providing precision tightness testing and leak rectification.
Gas leaks aren’t a guessing game, and they aren’t something to sit on. If you suspect a drop in pressure or smell gas in your property, you need definitive answers and immediate action. At iWarm, we bypass the guesswork. We deploy systematic tightness testing and precision trace-and-access protocols to locate the exact point of failure on your gas installation, ensuring your property is made safe and compliant without unnecessary disruption.
Our Precision Leak Detection Process
We don’t just arrive and start tearing up floorboards. Identifying a gas leak requires a methodical approach to narrow down the specific zone of the gas carcass that has failed. Here is the exact process our engineers follow to locate and rectify escapes.
The “Leg Isolation” Strategy
When a drop is confirmed, we execute a targeted isolation strategy. After confirming the integrity of the primary meter installation (checking for let-by at the ECV), we systematically isolate each leg of the gas carcass. By capping off specific runs and re-testing with a digital manometer, we narrow the pressure drop down to a localised section of pipework. This strategic isolation minimises destructive access and allows us to focus our trace directly on the failing run.
Specialist Detection Equipment
Once the leaking leg is isolated, we trace the pipework using high-sensitivity combustible gas detectors (“gas sniffers”). These electronic sensors allow us to pinpoint the highest concentration of gas accumulation, even in concealed voids or behind boxing. Once we have the precise location, we expose the joint or section of pipe and confirm the micro-leak using specialise micro-porous Leak Detection Fluid (LDF), ensuring we are rectifying the exact point of failure.
Mechanical Repair
We don’t believe in temporary patches. Once the failed joint, degraded copper, or corroded steel pipework is exposed, we cut back to solid, sound pipework and execute a permanent mechanical or soldered repair. The entire system is then re-commissioned and subjected to a rigorous final tightness test to verify the integrity of the gas installation to current Gas Safety (Installation and Use) Regulations.
If the repair forms part of a wider system overhaul, we often advise running a full Chemical System Flushing or Magnacleanse System Flushing while the system is drained down to protect your primary appliances.

What to Do if You Smell Gas or Suspect a Tightness Drop
If you detect the smell of gas, immediate action is required to secure the environment before an engineer arrives.
- Isolate the Supply: Turn off the gas at the Emergency Control Valve (ECV) immediately. This is usually located next to your gas meter.
- Ventilate the Property: Open all windows and doors to allow the gas to dissipate and prevent accumulation.
- Eliminate Ignition Sources: Do not operate any electrical switches (turning them on or off can create a spark), do not smoke, and do not use naked flames.
A perceived gas smell is a major red flag, but a visual tightness test is the only definitive way to confirm carcass integrity. In cases where an installation is deemed immediately dangerous or immediately unsafe, the appliance or pipework will be capped, and under certain circumstances, RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations) protocols must be followed.
Often, what initially presents as an appliance lockout requiring Boiler Repairs or Boiler Servicing is actually a safety mechanism triggering due to a supply-side pressure drop. Once the network is repaired and verified, we can issue updated Gas Safety Certificates to ensure your paperwork is legally compliant.
Frequently Asked Questions
How do you find a gas leak behind a wall?
We avoid unnecessary damage by using a leg isolation strategy. We cap off different sections of the gas carcass and test the pressure. Once we isolate the specific pipe run that is losing pressure, we use electronic combustible gas detectors to pinpoint the highest gas concentration before exposing the pipe to confirm with Leak Detection Fluid.
Is a small gas smell normal around a meter or boiler?
No. A gas smell is never normal. Any drop registered on a U-gauge or digital manometer requires immediate investigation. If you smell gas, isolate the supply at the Emergency Control Valve (ECV) and contact a Gas Safe engineer immediately to perform a tightness test.
How long does a gas leak repair take?
The timeline is variable and split into two phases: testing and repair. The initial tightness testing and tracing can take anywhere from 30 minutes to a few hours depending on the complexity and accessibility of the pipework. The mechanical repair itself is usually swift once the exact point of failure is exposed.
Will a gas leak affect my boiler's performance?
Yes. A significant leak or a partially restricted supply can cause a pressure drop at the appliance. Modern boilers are equipped with safety sensors that will detect this low working pressure and lock the boiler out to prevent dangerous operation. Resolving the leak restores the correct working pressure.
What happens after the gas pipework is repaired?
Once the mechanical repair is completed, the entire installation is re-tested using a manometer to ensure zero pressure drop. The system is then re-commissioned, appliances are checked for safe operation, and we can issue a new Gas Safety Certificate to log the compliance of the newly repaired system.
