Spring Irrigation Startup for Chelmsford Lawns

We start booking Chelmsford spring startups in late March and begin turning systems on in mid-April once overnight temperatures consistently stay above 32 degrees. Most Chelmsford homeowners schedule their startup between April 15 and May 15. Waiting too long risks letting your lawn stress in dry spring weather, but turning on too early risks a late frost cracking a backflow preventer or exposed pipe. We keep an eye on local forecasts and will contact you if we need to push your appointment for a cold snap. The entire startup visit takes 30 to 45 minutes for a typical six- to eight-zone system. We bring the system up slowly, checking each zone for leaks, adjusting head heights that shifted over winter, and programming a spring watering schedule on your controller.

The most frequent discovery is cracked head casings, especially on the Hunter PGP and Rain Bird 5000 series rotors that are popular in Chelmsford installs from the 2000s. Plastic casings become brittle after ten-plus years and a single frost event can split them. We carry the common models on the truck and swap them on the spot for about $15 to $25 per head. Another common finding is shifted spray patterns — a head that covered the sidewalk planting strip last fall is now throwing water onto the driveway because soil movement tilted it a few degrees. Valve diaphragms that were fine in October sometimes stick after sitting idle all winter, requiring a quick disassembly and cleaning. We document anything we find and review it with you before leaving.
