MDIrrigation, we must be long lost brothers, since that is what I was going to say. I would like to add to
this, so here it goes.
It will be coming as fall gets closer. We will email our Winterization Notice to all of our customer base in october. We will then get a few replies saying my lawn guy is now doing them for $35.00 (yes, you heard it right and it happened even more last year). We got tired of explaining what they are about to do, so we now just tell them "no problem" and we note each customer for Spring Start Ups. We had a guy driving neighborhoods with a 5 gallon compressor in the back of his truck and he was having trouble plugging into the homes outlets because they were tripping. LOL
Anyway, even if you charge a normal rate, you better be ready for when you get the call saying, "you did not winterize my system properly" or a shut off that leaks / does not close all the way and the phone call at 10 pm on Thanksgiving. It happens to every irrigation contractor on the planet, so it will happen to you. I know, I know....but it is so easy, just blow air through the lines right? But when you have to fork out $400.00 for one backflow to keep that customer happy and keep the lawn account you will understand.
If you are doing all of their services; start up, backflow test, and blow out. Then I do understand, but if you are just wanting to make some extra money at the end of the year, then it is BS.
Try and work with a local "Irrigation Contractor" and network each others clients.
There are very few Lawn Companies around here (even the large companies) that do quality irrigation. Besides one or two, all of them end up call us real irrigation contractors when they need 2-wire system work, ground faults, locates or anything that does not involve fixing a head or nozzle. This is why we do charge them out the ass when it happens. They all try and take the blow out money from us (which is our end of the year stash), but when they need us we are suppose to now "work together" to help out a fellow green industry friend.
To those of you that do landscaping and irrigation and do it well, then you too understand where I am coming from.
I do not think people are trying to "not help you" but you have to understand that all of us did not have a forum when we got started, we all learned the hard way or did the proper research. I would be glad to explain the entire process we use to blow out, but you need to PM me and I would like to talk to you over the phone first.
Good Luck to you.
