It is more precisely known as hot water extraction, and is technically known as emulsification. Hot water allows the detergents to quickly emulsify the soils and the vacuum pulls them out. Every carpet manufacturer and consumer reports magazine recommends this method. Truck-mounted steam cleaning is simply the most powerful version of this method.
For carpet cleaning we charge by the square foot. A full house is a little more than an empty house (.40 cents/sq. ft. vs. .36 cents/sq.ft.). With a few details provided by you, we can give you a fairly accurate quote over the phone.
We carefully move and replace most furniture. We also then place protection under replaced furniture so the carpet can dry safely. This protects the carpet and the furniture.
Yes, all our work is guaranteed and we let you decide. There is no magic involved, just science. We can let you know what to expect before we do the work. If you're not happy with it, you don't pay.
We use safe, PH balanced detergents formulated for this system. Virtually all residue is extracted out. Specialty chemicals for sensitive conditions are available, or we can also just use hot water.
After testing fabric for color fastness, the same method is employed with a specially designed tool to reduce the PSI while retaining the cleaning advantages.
There can be add-on charges per your request, for example, deodorizing, carpet repairs or some red dye removal. We never charge for spot cleaning or working on tough soils, that's just part of our cleaning services.
Weather makes some difference to dry times, as does the condition and type of carpet it is. That said, most jobs dry in 8 to 12 hours.
