Winterizing your sprinkler system costs $91 on average, but you can expect to pay between $56 and $133 for this service. Preparing your sprinkler system for winter is a crucial step in protecting it during cold weather and ensuring it functions smoothly come spring. Let’s break down the costs of winterizing your sprinkler system to help you budget for this essential maintenance task.
Sprinkler System Winterization Cost Factors
Several factors can impact the cost of winterizing your sprinkler system. Here are the main variables that play into your budget.
Size of Yard
The cost to winterize a sprinkler system is $1 to $1.50 per square foot, assuming an average of 1 to 2 zones for every 50 square feet. Your final costs will vary depending on the number of zones, as well as the number of sprinkler heads per zone.
| Yard Size in Square Feet | Average Cost |
|---|---|
| 50 | $50–$75 |
| 100 | $100–$150 |
| 150 | $150–$225 |
| 200 | $200–$300 |
| 250 | $250–$375 |
| 300 | $300–$450 |
| 350 | $350–$525 |
| 400 | $400–$600 |
| 450 | $450–$675 |
| 500 | $500–$750 |
Number of Zones
The typical sprinkler winterization cost of $56 and $133 assumes that you have an irrigation system with three or four zones. You may have more or less depending on the size of your yard. The more zones you have, the more you’ll pay to prepare your sprinklers for freezing temperatures.
Here’s a breakdown of the average cost to winterize a sprinkler system based on the number of zones you have:
| Number of Zones | Average Cost |
|---|---|
| 1–2 | $50–$75 |
| 3–4 | $80–$100 |
| 5–6 | $100–$130 |
| 7–8 | $150–$250 |
Type of System
The cost to winterize a sprinkler system depends in part on how a service tech drains the water from your type of sprinkler system.
| Type of Sprinkler System | Cost Range |
|---|---|
| Manual Drain Valve | $75–$150 |
| Automatic Drain Valve | $90–$175 |
| Blowout Draining | $100–$250 |
Manual Drain Valve
The average cost to winterize a manual drain sprinkler system is $75 to $150. You drain these types of sprinkler systems by turning off your water main and then opening a drain value to release the trapped water.
Depending on the terrain of your property, water may drain away from the highest points of your yard but sit in lower ones. This presents a problem as any water remaining in the pipes is subject to freezing, which can damage your irrigation system.
Automatic Drain Valve
The average cost to winterize an automatic drain sprinkler is $90 to $175. These systems automatically drain as soon as you shut off your main water supply. However, like manual drain sprinklers, these systems are prone to trapping water in low spots.
Blowout Draining
The average cost for a sprinkler system blowout is $100 to $250. A sprinkler pro can perform this service on any kind of lawn sprinkler system, and because it uses high-pressure air to force water out of the pipes, it eliminates the problem of water sitting in low spots.
Even if you have a manual or automatic drain sprinkler, a service tech may suggest the blowout process if they feel that the elevation of your property won’t allow for proper draining.
Labor
Typically charging a flat rate of $75 to $150, hiring a local landscaping company is your best bet for winterization of your lawn sprinkler system. These professionals have all the skills and tools necessary to drain and winterize your sprinkler, no matter which style you have.
However, you also have the option to pay a nearby plumber a flat fee of $40 to $200 if you have a trusted pro in mind or local landscaping companies are too busy to fit you in. Plumbers tend to be slightly more expensive due to their advanced training and experience.
Time Frame
The time of year that you winterize your irrigation system affects how much you’ll pay. Many landscaping companies in colder climates focus on winterization at the end of fall. During this time, these pros may offer reduced rates as they’re already traveling around your area to complete these services.
If you wait a few weeks longer to winterize your sprinklers, perhaps so that you can offer your grass one last watering before deep freezes set in, your landscape company may charge you for a higher-priced service call.
Service Agreements
Many sprinkler winterization companies offer service contracts that cover irrigation system winterization, springtime activation, and sometimes summer inspections. Bundling these services often results in greater savings than if you were to schedule each individually.
Common Sprinkler Winterization Add-Ons
As you plan your sprinkler system winterization project, it’s a good idea to plan for the spring startup of your sprinkler system as well. Incorporating additional services into a comprehensive service contract can reduce your overall expenses. Your professional service provider may offer bundled deals during the winter, covering a range of services for the upcoming spring and summer seasons:
Lawn care costs: $50–$210 per visit
Lawn aeration costs: $100–$350
Sod replacement costs: $1,100–$3,000
Grass seeding costs: $0.10–$0.35 per square foot
Landscaping costs: $1,300–$6,100
Sprinkler Repair Costs
The cost to repair sprinklers averages between $130 and $420. Your final cost will depend on a few different factors, including the type of sprinkler system, the severity of the issue, the cost of replacement parts, labor expenses, and other related considerations.
Cost to Winterize a Sprinkler System Yourself
The cost to winterize a sprinkler system yourself can range from nothing but your time to about $30 to $60. If your land slopes enough to allow for complete drainage of a manual or automatic drain irrigation system, you may be able to complete winterization at no cost.
If your land is relatively flat, it will be safer to use the blowout method to force water out of your sprinkler system. To do this, you’ll need to rent an industrial air compressor, which typically costs $30 to $60 per day.
Take note that winterizing a sprinkler system yourself comes with risk. The water in your sprinkler system is pressurized, so you have to be careful when opening valves to keep from damaging your system or hurting yourself.
Keep in mind that an air compressor is a powerful piece of equipment that’s also capable of hurting you or your sprinkler pipes if you use it incorrectly. It’s vital that you carefully review your sprinkler system’s user manual to determine how much compressed air it can withstand.
DIY vs. Hiring a Pro
Assuming that you can winterize your irrigation system in one day, you may come out slightly ahead by paying for an air compressor rental rather than hiring a local pro.
However, when you consider the amount of time it will take you to do the job, the learning curve that comes with using an air compressor, and the risk that you don’t completely drain your irrigation system, it really makes sense to pay the extra money to hire a local sprinkler winterization professional to perform the work instead.
How to Save Money on Winterizing a Sprinkler System
If you’d rather not take the risks with DIY winterization but still want to save some money, consider the following tips:
Winterize early: Many businesses offer discounts if you schedule the service a few weeks before the first expected hard freeze.
Purchase a winterization and activation package: Look for service bundles that include winterization and spring activation, as these packages often come with significant discounts compared to booking each service separately.
Shop around: Compare quotes from multiple companies to find the best rates for your budget.
Perform basic maintenance before the technician arrives: DIY prep work, such as draining visible water from hoses and valves or clearing debris from sprinkler heads, can save the technician time and may lower your costs.
Look for seasonal promotions: Keep an eye out for end-of-season deals or promotional pricing, especially from companies looking to fill last-minute slots.
Join a maintenance plan: Some companies offer annual plans that include regular inspections, winterization, and activation at a lower overall cost.
Winterize Your Sprinkler System Early
As the end of fall approaches, start contacting local sprinkler winterization companies to learn about their rates. Remember that many offer discount pricing if you complete winterization by a certain date (typically a few weeks before the first anticipated hard freeze).
Pay for a Winterization and Activation Package
Seeing as you’ll need to pay a technician to return to your property to activate your sprinklers in the spring, look into purchasing a service bundle that includes both winterization and activation. In return for your purchase of a service contract, many companies will offer steep discounts.
When To Winterize Your Sprinkler System
The ideal time to winterize your sprinkler system typically falls in mid-to-late fall or early winter before the first hard frost hits your region. It's crucial to act before freezing temperatures settle in to prevent costly damage to the system.
When To Activate Your Sprinkler System
Activating your sprinkler system should coincide with the arrival of the growing season in your region. The ideal time to activate your sprinkler system typically falls in the early spring, once the threat of freezing temperatures has passed and your lawn and plants are beginning to emerge from dormancy. It's crucial to wait until the risk of frost is minimal, as turning on your sprinklers prematurely can lead to damage if water freezes in the system.

Frequently Asked Questions
If you live in a region with freezing temperatures, winterizing your sprinkler system is essential to prevent damage from frozen pipes. However, winterization isn't necessary if you're in a warmer climate, such as Florida or the Southwest, since frigid weather is extremely rare in these regions. Be sure to assess your local climate and keep an eye on weather forecasts to determine whether winterizing is needed for your system.
You should winterize your sprinkler system before the first deep freeze hits in your area. In most regions, this typically happens near the end of fall, but the timing can vary based on your location. Always monitor local weather forecasts to ensure you complete the sprinkler winterization process before temperatures start to drop significantly.
To avoid damage to the pipes, you should wait to activate your sprinkler system until after the last deep freeze of the season. The exact timing depends on your location, so keep an eye on local weather forecasts. Alternatively, consult a local landscaping company familiar with your area's climate for guidance on the best time to reactivate your system.
Activating a sprinkler system costs between $40 and $150 on average. This service usually includes turning the water back on, inspecting the system for any damage, and adjusting the timers and schedules to ensure they’re set and working properly. Prices may vary depending on your location and the complexity of your system.
