AVOID AT ALL COSTS
The plumber that unblocked our toilet threw the dirty water from the toilet pipe outside on our doorstep! After I told him that is was illegal to have human waste on the street he told me it wasn't and i should clear it for him. Never ever again! Its not cheap, but I was prepared to pay double the €500 he charged for 2 hours work but the whole street was contaminated and smelled. We had to replace the door mat and close the business to clean up after this so called plumber. Its a shame i cant put pictures online of this companies work because they are shocking.
They also operate under the name ARL in Rotterdam as thats on the factuur.
UPDATE - We had a visit from the local council because someone took pictures and reported to the health department which i should have done also, if it was not for the fact I was in shock after this companies work.
