Written by HomeAdvisor.On average, you’ll spend $90 or between $56 and $133. In northern and some desert climates, where temperatures regularly drop below 32 degrees Fahrenheit, you’ll often need to blow out your sprinklers to avoid them freezing and ruining your system. It costs significantly more to repair or replace that system if you forget. If you leave water in your system, it can freeze, expand, and cause ruptures and leaks underground.
Let's calculate cost data for you. Where are you located?

Winterizing your sprinkler system costs about $50 to $200, depending on how many zones you have. Large properties with five or more zones may cost a bit more. Winterizing a sprinkler system typically includes:
Blowing out the pipes
Shutting off the main water supply
Inspecting the box
Turning off any injection systems
Draining the backflow preventer
Typically, you’ll hire your landscaper to do this, and in some cases they’ll include it in your seasonal landscaping and snow removal subscription. During the process, they’ll also check the box and make sure all the water is turned off to your system. Unless your pro finds something broken, all the money comes from paying for labor and overhead. Overhead includes driving to the site, insurance, and any licenses needed in your area.
On average, blowing out your sprinklers costs $50 to $200. The main part of winterizing your sprinkler system is blowing out the pipes; you’ll do this with an air compressor. However, too much air can harm the pipes, so it’s usually best to hire a professional. You can often get this included in your landscaping contract for the end of the season.
If you decide to go this route yourself, take note of a few things:
You can rent an air compressor for $30 to $100 per day.
Don’t exceed 50 PSI on your air compressor. Too much pressure can harm your sprinkler system.
Don’t forget to drain the other components of your system.
Be sure to turn off the main water supply.
Given the cost of an air compressor and the danger of hurting the system, consider hiring a professional instead.
Most homes have at least two zones. Usually, you’ll find your front yard has about two zones, and your back yard has two or more zones. Zones are separate systems within the ground, which allows you to water only a portion of the yard at a time. Homes with lower water pressure often have more zones.
Zone | Cost |
---|---|
1 – 2 | $50 – $100 |
3 – 4 | $75 – $100 |
5 – 6 | $100 – $150 |
7 – 8 | $150 – $200 |
After your irrigation system is clear of standing water, you only need to turn off the water supply valve and the controller. These tasks could only take a few minutes. Your plumber or landscaper may do it for you as part of the winterization service. If you don't feel comfortable doing it yourself, ask to be sure.
There aren’t many things you can do to reduce the cost of winterizing your sprinkler system, but there are a few cost factors that may come into play. However, always check with your landscaping service provider to see if they have any deals.
Automatic drain valves cost $5 to $80 a piece, not including installation. If this is the only method, winterization might cost you only $50 to $150, as it involves simply shutting off the water and backflow preventer. The same is true for manual valves, since they’re easier to access.
However, they shouldn’t replace the need to blow out the pipes at the end of the season, but they do help in case you get a late or early freeze.
You’ll want these installed when you put in a new system.
Professionals recommend still getting a blowout before the winter. They work by opening when the water pressure in your lines drops, so they continuously drain the pipes after use.
Since they’re underground, they can become clogged or malfunction, putting your pipes at risk.
Your professional will know when the best time to blow out your sprinklers is. They’ll often offer deals for a short window in the fall, when they’re out working on other customers' lawns. Grouping the service into a few days helps save the pro money—savings they can pass along to you. Actual savings will vary between landscaping companies.
The only real difference between an above- and below-ground system is the need for insulating the pipes. Although not always the case, which depends on the type of material being used, your professional might recommend insulating them. Everything else about the process remains the same.
In the spring, you’ll need your pro to come out and reactivate the system, which they’ll often offer as part of a summer landscaping service contract. Getting the system ready for irrigation season costs $50 to $150. The service often comes at a flat rate. The process entails much more than just turning on the water main and hoping for the best.
Your professional will:
Inspect and clean the backflow preventer
Turn on your water supply
Build pressure slowly to avoid damaging the valves and heads
Identify possible leaks
Test your sprinkler system by zone
Clean sprinkler heads
Plan for repairs, if needed. It may not include additional charges for repairs or necessary upgrades.
Activation occasionally shows problems in the sprinkler system that require replacement. Plumbers may charge a flat rate per item or divide up the estimate into parts and labor. In addition to the average hourly labor charge of $50 to $200 for removal of broken parts and installation of equipment, homeowners can expect to pay these prices for new pieces:
Part | Cost Range |
---|---|
Sprinkler Heads | $2 – $25 each |
Valves | $5 – $40 each |
PVC Pipe | $0.50 – $2 per linear foot |
Connectors | $0.50 – $5 each |
When you open up your sprinklers in the spring, consider adding in other services as part of a service contract to lower your overall costs. Your professional might offer deals in the winter to sign up for a bundle of services for the spring and summer.
Landscaping Maintenance | $140 per service |
Lawn Aeration | $125 per service |
Sod Replacement | $1 – $2 per sq. ft. |
Sprinkler system obstructions require a little clever pruning and maintenance. Your lawn and shrubs may grow, but your sprinklers don’t move. You can trim the shrubs back or relocate the heads, a much costlier option.
Lawn aeration costs $125 on average and won’t affect your sprinkler needs or costs. But, it will help your lawn grow more green and lush.
New sod installation costs $1–$2 per square foot. With regular irrigation, you generally won’t need this service, but it’s a good way to get a jump start on a lush, green lawn. It’s also great to pair with additions or repairs to subsurface irrigation systems.
A tune-up costs $100 on average and can help pros spot problems before they become emergency issues, like seeing a leak before it becomes a completely broken system.
A tune-up includes:
Visual inspection of the sprinkler heads and valves
Testing system for pressure and function
Cleaning and redirecting heads
Sprinkler system repairs cost $250, which a tune-up may help avoid. This includes replacing broken parts like sprinkler heads. During the spring and summer, you might start to see an area of your lawn or garden that looks drier than other areas.
If so, it might be a good idea to check and see if that sprinkler head is clogged. Dirt and debris can easily block these parts, trapping them in the ground. Your professional can clean out the heads so they work properly.
Homeowners who need to use an air compressor to blow out a sprinkler system may pay almost as much to rent the equipment ($30 to $60 per day) as the $75 average to have a professional do it for them.
Some systems are designed to automatically force out water when the controller shuts down, making the remaining work short and simple for a homeowner to do. If you aren't sure what type of setup you have, or you don't feel comfortable opening your valves, you're better off hiring a pro.
Many companies offer prepaid service plans for yearly sprinkler maintenance; it’s usually cheaper than paying when the pro completes the work. These agreements may feature:
Lower fees for flat rate services
Discounts on extra work, like repairs
Ability to choose a plan by the individual service or the year
To save money, handy homeowners may be able to do many of these tasks on their own:
Manually or automatically the drain valves
Turn off the water supply
Shut off the controller
Test the system by zone
Clean or reposition the sprinkler heads
The best time to winterize sprinklers comes in the fall before freezing temperatures hit, but after the grass doesn’t need water, which generally happens towards late September through the end of October. Homeowners must avoid leaving water in pipes that could freeze.
To open up a sprinkler system in the spring, wait until low temperatures consistently sit above 32 degrees Fahrenheit to turn on your sprinkler system for the year. Although you can test your irrigation any time after that point, you may not need to use it until later in the spring.
On average, homeowners will pay about $20 to $50 per month to use their sprinkler system. The typical American home uses 90 gallons per day on irrigation, which represents about 30% of a property's total water usage. You can reduce your usage and increase the effectiveness of watering by doing it in the early morning hours.
Activation | $50 – $150 |
Tune-Up | $100 |
Winterization | $50 – $200 |
Water Usage* | $100 – $300 |
Total | $300 – $750 |
It takes more professionals less than an hour to winterize a sprinkler system. They also generally don’t need you to be there to get the job done since access is all from the home’s exterior. However, some homes have an interior shut-off valve for the outside water, which needs to be turned off.
Underground sprinklers can freeze once the ground temperatures remain consistently below zero. The depth of your sprinkler system determines this. If your system sits below the frost line, it likely won’t freeze until deep winter. However, if it’s near the surface, you can see freezing at air temperatures slightly below freezing.
