Do you have an elderly pet that just makes it to the bathroom outside any longer? Lots of urine spots around the house? Cat throw up in the living room? We can generally take care of all of that for you. We carry several specialty products on our truck to deal with these situations. Sometimes we can apply a topical treatment and the problem goes away. Sometimes we have to do a subsurface treatment to the carpet to get rid of the problem. Sometimes we are going to suggest you just replace the carpet because it, the pad and subfloor is saturated with urine. We have a special UV light that we use that shows the location of the problem. Remember, what you see on top of the carpet is just the top of the spot, think about an iceberg. The spot is much larger in the carpet than it is on top of it.
