Even if you can't see where the accident has happened but you can smell it, we have an awesome tool that will detect where the accident was and remove the odour for you, and most of the time we can remove the stain as well, if it is a fresh stain, if it's been there for a long time, it may have already permanently stained the carpet fibres, but if we can't get rid of the stain, you can bet no one else can either, we've had success with some pretty awful pet accidents. So give us a call FIRST before you try to treat it yourself, you might set the stain if you don't know what you're doing.
