If I have dry rot in two rooms at the front of the house i.e bedroom and front room. Does that mean that the whole house is full of dry rot?
Not necessarily but it does mean that a specialist survey is urgently required ! Because dry rot – if that is what it is – has the capacity to spread quickly to other areas of the property in search of more timber to attack. So any delay could be costly in terms of repair bills. However if it turns out to be wet rot – a qualified surveyor will be able to identify it one way or the other – then the risks are not so great but either way timber decay at ground and first floor level indicates a serious water ingress problem in this area of the house which will need repairing urgently.
