Installation in this plan means two different jobs, and they should not be priced as if they were one.
New installation is for ground that has never had coverage, or for a piece of the property the original system never reached. A lawn extended after a build. A strip along a new fence. A bed that has been hand-watered for years.
An upgrade is for a system that is already in the ground. New heads, new valves, a smart controller, a zone rebuilt because the old one cannot cover what is there now. On an older Bear Lake system that is often the better spend. The pipe can stay. The parts that waste water get replaced.
Why there is no package price
Culinary water, secondary water, and private sources all show up around this lake. Lot sizes run from a town lot in Paris or Montpelier to a long shoreline parcel. A flat “system price” would be right for one of those and wrong for the rest.
The quote is built from the property. You get the number in writing before any trench is opened. If the scope changes once the ground is open, you hear about it before the extra work happens.
After it is in
A new or expanded system still has to be started in the spring and emptied in the fall. Those are separate visits: spring startup and sprinkler blowouts. A system that is already failing, rather than missing coverage, is a repair.
Seasonal maintenance, the bi-weekly look through the growing season, is what keeps a new system from running a stuck valve all month on an empty cabin. That visit is described on the irrigation page, and it is one of the four recurring lines in a property care bundle.
