A friend has just has been advised that her boiler is unsafe as the sealing around the balance flue is inadequate. Is there an easy remedy for this.
Is it as simple as injecting a heat-proof sealant around the existing flue is is it indicative of a more serious installation problem?

More information would be a help here.
Make and model of boiler.
Where is the problem? Flue ducting, boiler conection , around teminal, brickwork etc.

My friend has been advised that combustion prducts are re-entering the house, probably alongside the flue. There are small gaps in the rendering around the flue on the outside. Difficult to see if there's any problem elsewhere.

Products of combustion spilling into the property would be immediatly dangerous and I would expect the gas operative to disconnect the boiler from the gas supply and cap the pipework.
It should say on the paperwork left where the problem stems from.
On that model the flue cannot be removed for inspection without removing the boiler first. If it is proved that combustion gas is getting in between the air intake and the building fabric then repointing around the flue and render would be the cure.
A high temerature silicon such as 'Plumbaflue' would also make an acceptable seal.
