Do Companies Offer Discounts for Multiple Services? Winterization Mistakes to Avoid (and Why Blowing Out All the Water Matters)

Yes—many lawn and irrigation companies offer bundle discounts when you book multiple services, especially in fall. As for winterization, the biggest mistakes are skipping a full blowout, using the wrong air pressure, and ignoring the backflow. Leave water behind and it can freeze, expand, and crack pipes, valves, and sprinkler heads.

First things first: what happens if you don’t blow out all the water

 Think of water left in your sprinkler lines like a forgotten soda can in the freezer. It expands. It pushes. And it breaks things you can’t see—until spring. Even a small pocket of water can split a backflow preventer, crack a PVC elbow, or pop a sprinkler head. The result? Soggy spots, surprise geysers, sky-high water bills, and repairs that cost much more than a fall blowout.

A quick example: we once saw a system that “seemed fine” after a light winter. Come spring, zone three wouldn’t pressurize. A tiny sliver of frozen water had cracked a tee fitting underground. The yard looked fine from above but was turning into a sponge beneath. A full blowout the fall prior would have saved a dig and a week of frustration.

Common winterization mistakes homeowners make (and how to dodge them)

• Skipping the backflow: That brass device near your house? It’s the first to crack. It must be drained or blown out carefully.
• Using too much pressure: But what actually happens when you use too much air pressure during a blowout—and can it really damage your pipes? We’ll cover that in our next post, “Can You Damage Pipes by Over-Blowing During Sprinkler Winterization? How to Avoid It.”
• Not cycling each zone long enough: A quick puff is not enough. Zones need repeated cycles until only a fine mist exits.
• Forgetting drip zones: Drip lines hide water in low spots and emitters. They need special attention.
• Ignoring controller settings: Leaving the timer “on” can re-pressurize the system if a valve leaks. Use “off” or “rain mode.”
• Closing valves in the wrong order: Trapped water between shut-offs and backflow can freeze into a solid plug.
• Waiting too late: After the first hard freeze, damage may have already started.

The better way to blow out: a simple step-by-step you can actually follow 

Here’s the easy, safe rhythm most pros use. Print it, snap it, keep it.

1. Power down the irrigation controller; set to off or rain mode.
2. Close the irrigation water supply valve inside the house.
3. Open test cocks on the backflow to relieve pressure; set handles at 45 degrees.
4. Connect a high-CFM air compressor to the blowout port. Keep pressure under 60 PSI for most systems; never exceed 80 PSI.
5. Run zone 1 for 2–3 minutes, then in 30–60 second bursts until only mist appears. Repeat for each zone.
6. Don’t forget drip: Use lower pressure and longer bursts to clear emitters and low spots.
7. Open low-point drains if installed. Leave backflow valves half-open to prevent trapping water.
8. Insulate the backflow/exposed piping with an outdoor-rated cover.
9. Label the controller with the blowout date so spring startup is a breeze.

Small extra: If you’re using a small home compressor, take your time. It may not have the airflow to push long runs quickly. Work in multiple passes and don’t crank the PSI to compensate.

Yes, companies offer discounts for multiple services—here’s how to ask (and save) 

Most reputable lawn and irrigation providers offer bundle pricing, especially in the fall and early spring. You’re not being pushy to ask—honestly, they expect it.

• Bundle smart: Pair fall blowout + spring startup + mid-season check. Many homeowners also add backflow testing.
• Ask about seasonal packages: Fall “winter-ready” bundles may include blowout, gutter clean, and shut-off valve inspections.
• Look for neighbor or route discounts: If two or more homes book together, crews save drive time and you often save 10–15%.
• Prepay incentives: Paying upfront for a year of service (startup, mid-season tune-up, winterization) can trim the total.
• Add-on logic: If you’re already scheduling a blowout, adding a system audit or nozzle swap is usually cheaper than a separate visit.

A quick rule of thumb: Bundling 2–3 irrigation services commonly saves 10–20% compared to à la carte. It’s worth a friendly, “Do you offer discounts for multiple services?” You might be pleasantly surprised.

DIY or call a pro? A friendly reality check 

If you have a high-CFM compressor, know your system layout, and stay under safe PSI, DIY can work. But if you’re unsure about:

• Backflow handling
• Drip zones and low spots
• Odd controller behavior or stuck valves
• Large systems with long runs …then a professional blowout is cheaper than a spring repair. And yes, scheduling earlier than the first hard freeze is the winning move.
