Thank you everyone
A bit more info..
There are no carpets in the house now, but there were in the two bedrooms upstairs before a hard bamboo floor was put an year ago
The living room had hard floor when they moved in, so that is ok. No bad smell there
I can feel the smell in the kitchen and it is still there even after a bottle of domestos on the tiles
I am 9 months pregnant with baby 2 and getting really desperate as the more info I dig up, the more likely it seems that the lovely new floor needs to go and underneath it lies the problem. We have tried soda, vinegar, air purifier, essential oils, and enzyme cleaners on the floors. The smell has not changed a bit
I am at a point where I am looking for a company to advise on the best way forward
For those of you that had your underfloor treated/changed, did the people that do the job have any cat odour removal experience or were they normal carpenters? How much does it roughly cost for 2 not big rooms?
Thank you
