How much does a sprinkler blowout cost in Virginia?
A blowout is priced by the job, not at a flat rate: the price follows the number of zones, the access to the blowout fitting and any backflow device work. Get two or three written quotes that say what is included, and ask whether spring startup is bundled.

Step by step
Read when to stop and call a pro, further down this page, before you start.
Step 1: Count your zones
Count the zones on the controller and note how many heads each has, since the work is done zone by zone.[4]
Step 2: Find the blowout fitting
Locate the air connection on the mainline and the shut-off valve, and tell the contractor where they are.
Step 3: Note the backflow device
Tell each bidder where the backflow preventer is and whether it is insulated or in an enclosure.[1]
Step 4: Ask what the price includes
Ask whether the price covers the controller, valve boxes, the backflow device and spring startup.[4]
Step 5: Get written quotes
Ask two or three contractors for a written quote and compare what each includes, not just the total.[2]
Step 6: Check the licence
Look up each contractor on DPOR's licence lookup before you book.[3]
A sprinkler blowout has no standard Virginia price, so treat any single number you read online with caution. What helps is knowing what the price is made of and making every bidder quote the same job. Rain Bird says local irrigation contractors usually offer the blowout for a fee that may also include spring startup.[4]
The cost follows the work and the equipment, not a flat rate.
What drives the price
Zones and heads. Compressed air is forced through the mainline, the control valves, the lateral pipes and out of the sprinkler heads, which is why the work goes zone by zone.[4] Do not blow any zone for more than 2 minutes at a time, and repeat the cycle two or more times until nothing more than a fine mist comes from the heads.[4] A ten-zone yard takes a lot longer than a three-zone one, and the price follows the time.
Equipment. Rain Bird says to rent or buy a compressor that delivers 10 to 25 cubic feet per minute.[4] A contractor owns one and brings it. Rain Bird says how extensive the system is and what equipment it has may lead you to choose a professional who is fully equipped for the work.[4]
Access to the blowout fitting. A fitting in an easy spot in a basement is a quick connection. One buried in a valve box, or missing, takes more time. In Chesterfield County a blow-off connection must be installed after the backflow prevention assembly, not upstream of it.[1] A fitting in the wrong place can mean plumbing work before the blowout.
The backflow device. Chesterfield County says its backflow assemblies must be protected from freezing, with a freeze-resistant model or an approved insulated enclosure as options.[1] Covering the device may be part of the visit or a separate line on the quote. Testing it is a different service; see what backflow testing costs in Virginia.
Bundling. Some contractors include the spring startup in the fall price. Compare totals only if both quotes cover the same visits.
What to ask for in a written quote
- The number of zones covered, and what happens if there are more than you counted.
- Whether the price includes controller shutdown, insulating valves and the backflow device, and a spring startup.
- What the contractor does if a leak or cracked pipe turns up, and whether repairs need your approval first.
- The contractor's DPOR licence number, which you can check on DPOR's licence lookup.[3]
Licences and paperwork
DPOR's guide says a Virginia contractor's licence is required when the work is valued at $1,000 or more.[2] The threshold matters most if repairs are found. The Board for Contractors defines landscape irrigation contracting as installation, repair, improvement or removal of irrigation sprinkler systems.[5] For repair work, Virginia law requires all licensed contractors to provide a written contract for residential work.[2]
Doing it yourself
A rented compressor of the right size can bring the cost down, as long as you can follow the limits in how to winterize a sprinkler system. If you are unsure, read whether to hire someone to blow out your lines. A cracked pipe next spring costs more than any blowout does.
Stop and call a pro if
- The quote is for repair, not a blowout. DPOR's guide says a Virginia contractor's licence is required when the work is valued at $1,000 or more.[2]
- The backflow device needs to be opened or tested. Leave that to a certified tester.
- A contractor wants payment up front with nothing in writing. Virginia law requires all licensed contractors to provide a written contract for residential work.[2]

Common questions
- Is there a standard price for a sprinkler blowout in Virginia?
- Not one we can point to with a date. Rain Bird says local irrigation contractors usually offer the blowout for a fee that may also include spring startup, and the fee varies by contractor. Ask for a written quote that lists the zones covered and anything extra.
- What makes one blowout quote higher than another?
- The number of zones and heads, how easy the blowout fitting is to reach, whether a backflow device needs freeze protection, and whether spring startup is bundled. Rain Bird says how extensive the system is and what equipment it has may lead you to choose a professional who is fully equipped for the work.
- Does a contractor need a licence for a blowout?
- Not necessarily. DPOR's guide says a Virginia contractor's licence is required when the work is valued at $1,000 or more, and a routine blowout is usually well below that. A repair found afterwards can cross it. The Board for Contractors defines landscape irrigation contracting as installation, repair, improvement or removal of irrigation sprinkler systems.
- Should I get a written contract for a blowout?
- For a small seasonal visit a written quote or invoice is usually enough. For repair work Virginia law requires all licensed contractors to provide a written contract for residential work, so ask for one before cracked pipe or valves are replaced.
- Is it cheaper to do it myself?
- Sometimes. Renting a compressor of 10 to 25 cubic feet per minute and doing the work yourself avoids the contractor's fee, but you take on the risk. A mistake can crack pipe or damage sprinkler drives, and a repair costs more than a blowout does.
