Mike, you indicate that you have been quoted for both $2.50 a square ft and also $35.00 a sq. ft. Clean Agent systems, like FM-200, ECARO-25, or the fluids, are gaseous agents and the quantity is determined by the protected room's volume. The industry norm is to provide a cubic foot estimate rather than a square foot because the room's height affects the overall square foot area. Typically, a ROM (Rough Order of Magnitude) or Ballpark pricing would range is based upon the following room sizes:
Room size in square feet: Price per Cubic Foot:
50-300 sq. ft. $8-$30.00 per cu. ft.
300-500 sq. ft. 6-8.00 per cu. ft.
500-1,000 sq. ft. 3-8 per cu. ft.
1,000-5,000 sq. ft. 2-3.00 per cu. ft.
5,000-10,000 sq. ft. 2.00 +/- per cu. ft.
As you can see, the price per cubic foot decreases as the volume increases. Can you tell me the dimensions of your room including the height?
