Did a job a few weeks ago, couple had 2 puppies which had a few accidents on the carpet in 2 rooms.
Cleaned as normal with urine neut. & sanitiser.
Got a call back a week later, still a strong urine smell.
I suggested that it may have soaked through to the underlay.
She said that her boyfriend who was a trainee carpet fitter had replaced the underlay throughout the day before the 1st clean was done.
Agreed to go back, on my hands and knees with my nose close to the floor managed to locate where they pee'd, right in the middle of the room, cleaned throughout again, this time really blitzing the affected areas with the same again.
Upon completion there was no hint of a smell, even with nose to the carpet and customer said she was happy.
Got another call today saying the smell had returned again and could I do anything else.
I suggested that maybe the backing was contaminated and had resoiled the underlay and unless he was going to pull up the whole carpet there is not alot else I can do about it.
Right or wrong?
Anything else I could try?
