Hi,

We've recently moved into a new house and have noticed a strange smell in
one of the bedrooms, it was present when the house was empty i.e. before we
moved in and remained despite having had the carpets cleaned. We've
(temporarily) sealed up the vent to the bricked up fire place to see if it
was coming from there, no luck. There's nothing to smell in the loft space
above the room either.

My suspicion lies with a brown stain on the ceiling directly under the
central heating expansion tank, it's old and not spreading but how feasible
is it that this could be the source of the pong. My initial impression is to
paint over it with an oil-based paint and then finish with a normal white
emulsion; assuming that this is the cause is this strategy likely to work?

Thanks



Could be a dead rodent under the floor? In which case the
smell will fade over a few weeks.
