Can anyone advise if this is the early stages of dry rot, or is it just aged and damaged floor boards.
How would’ve the best to handle the damaged areas of the boards or do they all need to be replaced ?
Thanks

Impossible to say 100% but very probably not, just looks like general rot, or even just damage, sorry photos are very poor. Lift the board and check for hyphae and mycelium. I can't see any iron stains which implies that the boards have never got seriously wet. Somewhat counter intuitively dry rot only takes hold in exceptionally damp conditions, your boards don't look like they have ever been that wet. It's called dry rot because once the spores have germinated, hyphae and mycellium propogated the organism can survive on relatively normal levels of timber moisture, although it will be less vigorous, as long as it can travel to areas with more nutrients as local ones are exhausted.
Taking in focus photos in good light helps, as does taking wide shots as well as close ups.
Cannot see any face nails, are the boards tongue and grooved? Maybe the damage is a goriila like a plumber brute forcing a board up rather than bothering to cut the tongues.
Thank you for your response. I will do as you suggested and lift and replace the boards that are damaged if I find no evidence of anything untoward underneath as you mentioned. Was just frightened that there was more than just old or damaged wood before I put me flooring on top. Thanks again.
