If you are thinking of having a New Sprinkler System Installed, here are a few key points to consider.

CMG Installs inline drains in all our sprinkler systems.  When the sprinkler system is not in use or turned off, the pipes drain underground.  This means that the sprinkler pipes will never freeze regardless of the temperature.  This also means no WINTERIZATION or other maintenance is required.  Just turn off the sprinkler system and the in-line drains will do the rest.

We install Rain/Freeze Sensors on many of our new sprinkler systems and a large number of existing sprinkler systems.  It turns off your sprinkler system when there is nobody available to turn it off.  For example — If your sprinkler is scheduled to water at 4AM and you are asleep and a heavy thunderstorm starts a few minutes later, the Rain / Freeze Sensor will turn off the sprinkler system.  The same thing goes while you are away on vacation.  When things dry out enough to water again, the Rain/Freeze Sensor will turn the sprinkler system back on again.

If you have drainage problems with your home or business, CMG can help.  Since 1993 we have come across virtually every home drainage problemCMG provides free drainage estimates and will design a drainage system to fit your specific needs.  We utilize in our Drainage Systems: French Drains, Surface Drains, Channel Drains, Basin Drains, Trench Drains, Basement Drains, and Sump Pumps.

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 sprinkler systems,  repairing sprinkler systems, and designing and installing drainage systems.  Like everyone,  I have made mistakes, but I have learned from them.  As a result I get calls from time to time from other sprinkler and drainage 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.

Please leave a comment or feedback in an email about our website.
