Winterize Sprinkler System Cost Factors
Several factors influence the cost to winterize a sprinkler system. Understanding these can help you budget and make informed decisions.
Type of Sprinkler System
The type of sprinkler system you have plays a big role in winterization costs. Residential systems are less expensive to winterize than commercial or complex systems. Drip and above-ground systems are simpler, while in-ground systems with advanced controllers or multiple valve types require more time and expertise. Older systems or those with outdated technology may also need extra care, increasing the price.
| System Type | Average Winterization Cost |
|---|---|
| Manual drain valve | $75–$150 |
| Automatic drain valve | $90–$175 |
| Blowout draining | $100–$250 |
Size
The number of zones in your system is a primary cost factor. Most standard quotes cover up to six zones, with a per-zone fee ranging from $10 to $20 for additional areas. Larger yards with more extensive coverage increase the total cost, as each zone requires separate attention.
| Zones | Description | Average Cost |
|---|---|---|
| 1–4 | Small system, single yard area | $60–$100 |
| 5–6 | Standard home system, average yard | $100–$130 |
| 9–12 | Large yard or multiple areas | $150–$250 |
| 13+ | Estate or commercial property | $250+ |
Frequency
Most homeowners winterize their sprinkler systems once per year, just before the first freeze. In areas with unpredictable weather or very harsh winters, semiannual service or bundled seasonal maintenance may be recommended. Some companies offer annual contracts, which can lower your per-visit cost compared to single appointments, while also providing peace of mind.
Materials
Winterizing a sprinkler system requires a few key materials and tools. For DIYers, the most significant expense is renting or buying an air compressor strong enough for blowout, plus the right adapters. Professionals bring their own equipment and may use higher-grade tools for a more reliable job.
Labor
Sprinkler winterization is performed by irrigation specialists, landscapers, or plumbers. Most charge a flat fee for up to a set number of zones, with additional per-zone fees for larger systems. Hourly labor rates for irrigation or landscaping pros range from $75 to $150 per hour, while plumbers charge up to $200 per hour.
A service includes full blowout, inspection, controller adjustment, and sometimes travel fees. In high-demand areas or regions with a short winterization window, rates may be higher, and minimum service charges may apply.
Location
Where you live directly impacts the cost to winterize a sprinkler system. Regions with harsher winters, like the Northeast or Midwest, tend to have higher demand and slightly higher prices. Urban areas or places with higher labor costs also see increased rates. If your system is hard to access (for example, in a fenced or densely landscaped yard), expect a small upcharge.
Tipping
Tipping is not required for sprinkler winterization, but it’s appreciated for exceptional service, especially if your system is complex or the pro goes above and beyond. If you choose to tip, $10 to $20 is a reasonable amount. You can also show appreciation by offering a warm beverage or leaving a positive review.

How Often Should You Winterize Your Sprinkler System?
For most climates, you should winterize your sprinkler system once a year, ideally before the first hard freeze. Early winterization is especially important in regions with unpredictable fall weather. If you live in an area with frequent freeze-thaw cycles, you may want to consider a spring checkup or semiannual service.
Look for signs like dropping temperatures, forecasted frost, or water left in lines after system shutdown. Skipping or delaying winterization can lead to burst pipes, cracked valves, costly repairs, or early sprinkler replacements—often far exceeding the cost of a professional winterization visit.
Cost of Common Sprinkler System Winterization Add-Ons
During winterization, you may encounter extra services or small repairs. Some add-ons are optional, while others are necessary if issues are discovered during the process. Here’s what you might see on your bill:
System inspection and repairs
Backflow preventer removal or insulation
Controller reprogramming
Valve or pipe repairs
Draining extra outdoor lines
Smart controller or freeze sensor upgrade
DIY Winterize a Sprinkler System vs. Hiring a Pro
You can winterize your sprinkler system yourself if you have the right tools and experience. The main DIY costs involve renting or buying a suitable air compressor and the required adapters. However, doing it yourself comes with risks—if you miss a step or fail to blow out all the water, you could face expensive repairs.
Professionals bring expertise, commercial-grade equipment, and insurance. Their flat-rate services include a full inspection, zone-by-zone blowout, and controller adjustments. This peace of mind may be worth the extra expense, especially for complex or high-value systems.
DIY is best for those with simple systems and mechanical know-how. For most homeowners, especially those with multi-zone or older systems, it’s safest to hire a pro.
Tips to Reduce Costs for Winterizing a Sprinkler System
You can take several steps to keep your sprinkler winterization costs in check:
Compare contractors: Get multiple quotes from local irrigation contractors to find the best value.
Schedule early in the season: Book your winterization before peak demand hits to lock in lower rates and better appointment times.
Bundle winterization services: Combine winterization with fall yard cleanup or other maintenance to take advantage of package pricing from local pros.
Maintain your system: Learn basic system maintenance, such as clearing debris from sprinkler heads, to minimize the need for repairs.
