Hippo Cleaning Services

Had basement area with yellow mold on carpet. About 100 sq ft total with perhaps 10% of the area covered with visible yellow mold spots. Called on Friday and was told cost would be $69 for cleaning and $20 to $80 for mold treatment. When technicion came on Monday, he was driving truck labeled "USA CleanMaster". He said carpet needed "deep cleaning" and cost was $200 plus tax. When I mentioned what I had been told over the phone, he said something like "they always underestimate". I didn't want to waste another day geting someone else so I had him do the cleaning. The mold "Treatment" was putting some type of enzyme into the hot water used to clean the carpet. It was not a separate treatment except to wait a few minutes after spraying it on. When the cleaning was done, the carpet was clean but I felt I was subject to a "bait and switch" and was charged about twice as much as I should have been. I called Rockville Carpet Cleaning MD and was basically told they were sorry but their quote of $69 for cleaning one room plus $20 to $80 more for mold treatment was an estimate. They said another $50 over their quoted upper cost value was no big deal.
