Very nice staff and very informative! We had actually went with AlpinePro because they offered baby safe carpet cleaning with this new machine they had so they didn't have to use any chemicals. We were SHOCKED as to how white our carpets turned! We had a service done just two months prior and this was 10x better then the other company (don't remember the name). The water that came out was actually black...we don't even wear shoes in the house.
I asked why they get the results they do and it was apparently due to some new tech machine they were using.
If you are cautious about chemicals and care about your pets/etc... these guys are the ones to call!
