Spring start-up and fall winterization are the two visits everyone knows about, and they bracket the season without covering it. The months in between are when the system works hardest and when most problems start.
Start-up and shutdown handle the two obvious jobs: pressurizing the system and getting the water out before it freezes. Neither one tells you how the system performed in July.


Say it is mid-July. When was the controller last adjusted? Probably at start-up, when it was cool and rainy. Those settings are wrong for the hottest, driest stretch of the year, and reprogramming it is a small hassle, which is exactly why most people never do it. Companies that maintain systems do it every day.
Summer is also the only time a technician can properly evaluate coverage, because shrubs, perennials, and ornamental grasses are at full size. A spray arc that was clear in May is often blocked by August, and you only see that with the system running during full growth.
Problems caught during a scheduled visit do not become service calls. And when a repair is needed between visits, a service call is $20 less at RainMaster with a maintenance plan, at $59 rather than $79.
Without regular visits, the sequence is: something breaks, you notice brown grass a week later, you call, and you wait for an opening during the busiest part of the season. An emergency visit runs $159. With a plan, a technician is already on the property on a schedule and most issues are found before they turn urgent.
Maintenance visits include the adjustments that keep water on target: heads realigned so they are not spraying the driveway or the siding, nozzles cleaned, heads raised that have settled below the canopy, run times corrected.
The waste you cannot see is the expensive kind. A head mowed over weeks ago can be pouring water into one spot every cycle. A valve that does not fully close weeps continuously. This happens to everyone, including us; our own technicians find issues at our own homes, and we inspect our systems more often than most people do.
Good maintenance companies in Eau Claire and the Twin Cities do not just keep a system running. They make sure it is using only as much water as the property actually needs.
Once a system goes down, brown spots appear quickly in summer heat, and they do not reverse on the same timeline. Expect to look at those spots for up to two weeks after the water comes back while the turf recovers, and longer if the damage went far enough that the area needs seed. Preventing brown spots through efficient, verified watering is dramatically easier than repairing them afterward.
Most system damage is accidental and unnoticed at the time.
None of these announce themselves. A technician on a schedule finds them before they get out of control.
A maintenance program spreads discovery across the year. Technicians find repair needs as they develop rather than presenting you with five problems at once during a single annual visit. Smaller repairs, caught earlier, spread out.
If you have invested thousands in plantings, an irrigation failure during a hot stretch puts all of it at risk, and mature plants are far more expensive to replace than to water. With significant money in the ground, a couple hundred dollars a year for maintenance is cheap insurance on the asset.
Beyond catching problems, a professional technician tells you things worth knowing: that you are watering too much or too little, that newer high-efficiency nozzles would cut run time on a zone, that the slope on the side yard needs cycle and soak, that your beds should be converted to drip. It is an extra set of experienced eyes on your lawn, your water use, and your budget.

Proper irrigation is foundational to the health of the lawn, and that means a system that does not let you down in the week it matters most. Ignore maintenance and the repairs generally cost more than the maintenance would have. If coverage failures have already left damage, pair the repair with the lawn care work needed to bring those areas back.

It usually pays for itself through water savings and avoided repairs. The arithmetic is straightforward: plans start at $179 a year, an emergency visit is $159, and replacing landscaping killed by a failed zone costs far more than either.
At least three: spring start-up, a midsummer check, and fall winterization. The midsummer visit is the one most homeowners skip and the one that catches blocked spray patterns, settled heads, and controller settings left on spring programming.
Yes, and it is not optional here. Lines are blown out with compressed air each fall because water left in a lateral, a head, or a backflow device freezes, expands, and splits it, which turns a routine visit into a spring repair bill.
Running every zone, checking and realigning heads, cleaning nozzles, raising settled heads, looking for leaks and pressure problems, verifying coverage, and adjusting the controller for the season. The technician should also tell you where the system is wasting water.
