My name is Blane Callen. I have owned and operated CMG Sprinklers and Drains since 1993.  I take great pride in my work.  The Letters “CMG” stand for the first letter of the first name of each of my children.  ( Chance, Melissa, Garrett )  = CMG

I have amassed a great deal of experience Designing and Installing Drainage Systems  Repairing Sprinkler Systems, and installing new Sprinkler SystemsIn the past 21 years, I have made mistakes, but I have learned from them.  The accumulated experience allows  me  to handle a wide variety of challenges in the areas listed above.   I get calls, from time-to-time,  from other Sprinkler and Drainage System companies that have run into a problem that they can’t handle.  I am always glad to help.

I usually don’t take money up front for Sprinkler Installation, Sprinkler Repair, or French Drain Installation.  I prefer that the customer pay me when the job is complete and they are happy with the work.  In a few cases on very large jobs I request a draw or outlay for parts.  The parts are delivered from my supplier to the address where the job is being done and equal the amount of the draw.  The parts stay on the premises until they are installed.
