Every zone blown until it runs dry, backflow winterized, controller shut down - $99 up to 8 zones, $7 per zone after that, and the zone count is confirmed with you on arrival, not discovered on the invoice. Plan+ members: included every fall, scheduled automatically.
Ten minutes with a rented tank isn't a blowout. This is the version where your system is actually empty when the ground freezes.
Compressed air at the right volume and safe pressure - high CFM, capped PSI - because too much pressure is how cheap blowouts crack fittings and melt gear drives. Each zone runs until the heads spit dry, not until the timer says move on.
Isolation valves closed, test cocks set to 45°, body drained. The backflow preventer is the most expensive part of your system to freeze - and the part drive-by services skip because it's not on a timer.
Set to off for the season so a warm week in November doesn't quietly water your frozen lawn. We note your spring settings so activation puts everything back the way you had it.
Photos of the drained backflow with your invoice, and your zone count on it - the +$7 math visible, not discovered. If we spot a cracked head or a weeping valve while we work, it goes in the report with the published repair price.
A $49 blowout only works at twenty stops a day - which means minutes per house, no backflow care, and heads left hissing. The repair bill from one cracked backflow preventer erases a decade of $70 savings. Our price covers doing the whole job, once, correctly - and it's published, so it can't creep on the driveway.
Book the sprinkler blowout and the First Frost Check together and save $30 - one truck roll, your sprinklers winterized and your furnace ready for the first cold night, done in a single appointment.
Hearthlight Plan+ covers home and yard: the fall blowout, the spring activation, and both seasonal HVAC checks - four services a year in two combined visits, all scheduled for you. $340/year.
Before the first hard freeze - along the Front Range that typically means early-to-mid October, and the Palmer Divide towns freeze days earlier than Denver does. Book in September; our routes run south county first for exactly that reason.
Yes - a proper blowout starts inside: we shut off your sprinkler supply valve (usually in the basement or crawl space) and need access to your controller. It takes someone home about the first five minutes and the last two; we text before arrival so you're never waiting on us.
Several Douglas County districts - Castle Rock Water among them - require periodic certified backflow testing. We're adding certified testing to the sprinkler lineup, and blowout customers are first in line when it goes live. One company for the whole sprinkler year is the goal.
