We attempted to clean our carpets after tenants moved out (medium amount of staining) with the rent it yourself carpet cleaning machines...BIG mistake! Evidently, we over saturated the carpet pad underneath and a brownish color kept seeping up to the top layer of the carpet fibers as the carpet was drying. Jeff from Genesis was very knowledgeable of this problem and applied a product to neutralize the musty smell from the carpet and applied another product to help with the PH imbalance (brownish color/seeping issue). Additionally, he came out the same day I called knowing time was an issue on our side. Lastly, he went the extra mile by coming out a second time to make sure the carpet was stain free after it had dried completely. Great customer service. I would highly recommend.
