  • Sprinkler System Portland Oregon

Sprinkler System Winterization & Spring Activation Services

For these services, we serve the Portland West Side, Beaverton, Tigard, Hillsboro, Lake Oswego, Tualatin and Sherwood. We specialize in the service and maintenance of sprinkler systems. We have full time irrigation technicians ready to perform your sprinkler system winterization and spring activation. These services ensure that your system is fully protected from damage that can occur during winter months. A description of our services are listed below. Please call today to schedule your sprinkler winterization or spring sprinkler activation.

Sprinkler Winterization Prices and Procedure

Most homeowners and even many lawn care or landscape professionals believe the only steps to winterizing a sprinkler system is to turn the system off for the winter and maybe open the drain valve. However, this practice still leaves the majority of your system full of water and susceptible to breaks, leaks, and costly repairs.

In order to fully protect your system, we offer the following 2 Options:

OPTION 1


Traditional Drain-Out Option

(One Technician Needed)
With this option we close off the water flow to the system, drain the majority of the water out of the lines and open valves on the system to allow for any remaining water to expand during freezing temperatures so parts of the system won’t break during freezing spells. We’ve been using this method for over 25 years and it seems to work well the vast majority of the time.

  1. Shut off water pressure to your irrigation system via main gate valve
  2. Open main drain valve at beginning of system to drain out main line
  3. Open drain valve inside valve manifold box (if one is installed) to drain lateral lines
  4. Manually open all electronic valves to allow lateral lines to drain into mainline
  5. Keep valve solenoids and bleeder valves open for winter
  6. Open bleeder screws on valves to allow lateral lines to drain into mainline
  7. Open test ports on backflow device in order to winterize backflow device
  8. Close gate valves on backflow device
  9. Close valve box lids, service is completed.
  10. Leave check-list on your door detailing the steps we took and notes regarding your system

 

DRAIN-OUT PRICING AS OF 09-15-2025

1-12 Zones = $110.00
13-18 Zones = $158.00
19-24 Zones = $190.00
25-30 Zones = $210.00
31+ Zones = $231.00

OPTION 2


Blow-Out Option

(Two Technicians Required)
With this option we completely evacuate all of the water from the sprinkler lines and valves using compressed air to blow out the lines. This method is common in states with colder climates but has become more commonly requested in recent years for customers who want that absolute level of protection.

  1. Shut off water pressure to your irrigation system via main gate valve
  2. Gain access to sprinkler controller (typically inside the garage)
  3. Hook up air compressor to test port on backflow device
  4. One technician opens up the first zone via the sprinkler controller
  5. Second technician powers on air compressor to blow water out of the main line and first zone
  6. Second technician turns off air compressor
  7. First technician changes to zone 2
  8. Second technician turns on air compressor to blow out zone 2
  9. This continues until all zones are evacuated of water
  10. Close valve box lids, service is completed.
  11. Leave note on your door to let you know service has been completed.

 

BLOW-OUT PRICING AS OF 09-15-2025

1-12 Zones = $200.00
13-18 Zones = $320.00
19-24 Zones = $390.00
25-30 Zones = $460.00
31+ Zones = $525.00

 

Please note:

  • Winterization and Spring Activation are bundled together and must be paid for at the same time in the fall. You will not be able to figure out how to start your system in the spring time without our Spring Activation Service and then you’ll be automatically signed up for our first batch of Spring Activations.
  • To keep these services as affordable as possible, we ask our clients to pre-pay for these services so that we can know ahead of scheduling which properties we’ll be working at ahead of time and route our technicians by neighborhood. Which keeps us more efficient.
  • Get in on Early-Bird pricing, if paid prior to Oct. 15th. Call office for details.
  • Winterzations need to be paid for by Nov. 30th to get in on the regular rates listed here. After that date we can still winterize your system, but it will be a standard Service Call at that point, and as such it will be done at our regular Service Call rate of $149.

Sprinkler System Activation/Spring Start-up Prices and Procedure.

Our spring sprinkler system activation is a detailed service call where we not only reverse the 9-step process above to re-pressurize your entire system, but we also include a full zone-by-zone inspection of your system to make sure your system gets started in full working order. We test every valve, every zone, and every head. Below is a summary of our spring activation procedure and pricing:

  1. Reverse each of the 8 steps above that were done for sprinkler winterization
  2. Check each valve that it opens and closes properly
  3. Check that electronic wiring is still secure
  4. Check each sprinkler head to be sure it’s operating correctly, fully retracting, and spraying the desired direction.
  5. Clean and/or replace any clogged filters or nozzles as necessary
  6. Check that there are no visible leaks at backflow device
  7. Check that there are no visible leaks at valve manifold
  8. Leave a check-list on your door detailing the steps we took and notes regarding your systems needs, if any.

Frequently Asked Questions

We schedule our services by neighborhood and also by date payment was received. So the sooner you call to schedule this service, the we will be able to get your service done. We try to get all of our winterizations done by Dec. 1st. But if you wait until November 25th to call us for this service, you’re sort of pressing your luck to get it done by that time. Still, we make every effort to get all of our winterizations done within a few weeks of your call and usually not later than Dec. 1st.

Similarly with Spring Activation – the sooner you get on our schedule, the sooner we’ll be able to get you in. But we also schedule these by neighborhood. So don’t expect us to come out in the first day or two. It may be a week or two before we get enough in your area to create a route for that area of town. Regardless, we do try to get all of our spring activations done by May 1st.

We will note that on your check-list if your system is in need of service, along with an accurate price quote to fix the issue. Then you can call and have us return to fix the issue, if that is your desire.

If you’re system was installed by our company in the last 5 years, yes. This protection is part of the warranty you received when you purchased your system from us. For everyone else however, unfortunately there is no way for us to extend the same guarantee. First, we don’t do a zone-by-zone inspection prior to winterization. So we don’t always know what condition the system is in when we arrive to winterize it. There may be issues at that time, but we won’t know until the spring activation. Second, many issues that arise with sprinkler systems can be just due to poor installation or normal wear and tear. Third, despite our best efforts to drain your system in the winter, there could be a head that isn’t draining properly, a pipe that is being squeezed by a tree root, or any number of other issues inside the system that lead to a break during the winter. We can’t be held responsible for every possibility. We do guarantee you that we will do the best possible job to drain out as much water as we can from every part of your irrigation system. We do this with trained technicians and every year we do this for over 650 customers with a very high success rate.

Both the drain-out and the blow-out option are great for protecting your irrigation system for the winter. It really just depends on your budget, level of risk you’re willing to accept, and preference. The drain-out option only requires one technician, so there is a good cost savings with that option. We’ve been doing winterizations that way for over 20 years and it seems to work very well in terms of protection the vast majority of the time. If you’re willing to accept a minor amount of risk and budget is a concern, we recommend this method. If you want to mitigate all risk and be 100% sure no water is left in the system and are willing to spend a little more, the blow-out option is definitely the best option to avoid all risk.

If you choose the drain-out option, we will not need access to the controller during winterization nor spring activation. We can access all of the valves from outside the house. If you choose the blow-out option we will need access to the controller for the winterization phase only. Our office will contact you to make arrangements for our technicians to get access to your controller on the set day.

If you happen to be home at the time of service, we will ask you if the repair is something you want us to do at that time. This way, you can save the cost of a separate service call. But if you are not home during the time of service (which is most often the case), we will leave a note regarding the repair needed and you will have to call us back to schedule a time to make that repair.

This isn’t something we generally offer as part of the start-up procedure. First, because most homeowners are not home when we come by to do the service. Second, because we haven’t allotted enough time for this. And third, because your programming doesn’t generally need to be changed from year to year. But if you happen to be home and it is something that doesn’t take us more than 5 minutes, we’ll typically go ahead and do this.

We do ask that you take a look over your sprinkler system within 30 days of our service. If we have missed something, we would like to know sooner rather than later. Also, keep in mind that if you find a valve or head that isn’t functioning properly in June, that it may have been working just fine when we did your spring activation in April. Irrigation components can break at any time. So again, please check your system after we are done and if you think we’ve missed something, we want to know about it sooner, rather than later. If necessary, we’ll send our technician out to fix whatever we missed.

No. Backflow testing is a totally separate service and needs to be done by a certified backflow tester. See our page about backflow testing for more information on who we recommend. We do work with your backflow device during spring activation. That is, we pressurize it and make sure it’s opening and closing like it’s supposed to so we can use the irrigation system. But that’s different than the pressure testing that is needed to make sure the backflow device is functioning properly. Here’s a good analogy: you take your car to a mechanic to get it serviced or tuned up. But you take it to the DEQ to make sure it’s passing emissions requirements. Consider our irrigation technicians the mechanic and our certified backflow tester is the DEQ. The certified backflow tester is just testing the system to make sure it’s preventing backflow like it’s supposed to. We’re just making sure the device is running.

We’ve had Jim Lewis come by and help us with the yards at two homes over 13 years now. Both involved deconstruction and renovation. We usually have tentative ideas that Jim helps us flesh out and improve. Then the crew arrives and magic occurs. We’ve also had Lewis Landscape Services come do the annual maintenance on our irrigation. That saves us headaches and the cost of replacing dead plants next year. The office staff is kind; the crews are great; and for Jim it’s personal. It’s your home and he wants it to be right for you.

I hired Lewis Landscape after receiving a well presented estimate accompanied by recent project photos. The price was fair and the quality met my expectations. My neighbors all commented on the craftsmanship. The paver patio and walkway are now the focal point of my home. Thanks for a job well done.
