Ammonia in urine causes health problems, especially for anyone with breathing or lung issues, but not only that. The real challenge is that most animals will return to the same spot to pee again and again. The smell emitted will fill the room and will very quickly make the room unbearable. Repeat incidents in the same area will cause the carpet fibres to break down, revealing the padding or the sub floor. Damage to wood sub floors is a very real possibility.  Avoid carpet damage or sub floor damage, protect your health, and make your home the best place for you and your pets by calling the expert carpet cleaners at Crystal Carpets!
