What is cheap in the tri-state area? Compared to most parts of the U.S. we pay less for fuel. As for everything else, things just seem to be more expensive. Housing, taxes, insurance, and labor, things just seem to cost more.
What about exterior cleaning? Well, as a pressure washing contractor for over 14 years now, I've seen prices rise all accross the spectrum. It depends on the method one uses to clean. Time, material, fuel, and labor are all factors. I have washed house for less than $200 when the customer had gotten quotes for over $700. The services were probably different. It may similarly be compared to a car wash. You can pay $10 to simply wash it, or $100 or more for a full detailed wash with all of the bells and whistles. It all depends on what your looking for.
We've started this company primarily washing mold from siding. It has slowly migrated toward roof cleaning, pool patio cleaning, vinyl fences, cement whitening, and more. House washing quotes can be given over the phone in most cases. Visit our wesite for contact info at http://www.thompsonpowerwashing.com/.
