Stone Oak winters are mild until a hard freeze splits an exposed backflow. We insulate before the front, then recharge in spring.
North SA master-planned communities with large multi-zone systems. San Antonio irrigation lives with limestone, caliche, pockets of black clay, Edwards Aquifer hard water, and long hot summers. Those conditions scale nozzles, walk heads out of grade, and punish weak valves.
Winterization & Spring Startup in Stone Oak
This is a Bexar County route we run weekly. We do not treat Stone Oak like a generic Texas suburb — the soil, the water, and the HOA clock on this street are what set the repair.
How the visit goes
1) Shut down and drain exposed assemblies.
2) Insulate the backflow.
3) Spring recharge with slow pressurization.
4) Set a summer schedule after the head check.
Local conditions
Hard water in Bexar County scales nozzles. Limestone and clay shift heads. If you want the neighborhood page, see sprinkler repair in Stone Oak.
What you can do before we arrive
Write down the station number, whether it fails only after rain, and whether the controller shows an error. Those three notes cut diagnostic time.
Parts and brands
Rain Bird, Hunter, Toro, Irritrol, Weathermatic, and K-Rain parts are not always interchangeable. On Stone Oak systems we document what is in the ground and match precipitation rates so one head does not drown a bed while another dusts the turf.
If a model is discontinued we install the closest hydraulic match and tell you what changed. We do not leave a mixed zone that cannot be scheduled honestly.

Quick question
Do San Antonio systems need a full blow-out? Rarely. Protect the above-grade backflow before a hard freeze, then recharge slowly in spring.
When to call
Call Sprinkler Repair Tech if a zone will not shut off, water is pooling toward a foundation, or half the yard is offline in Stone Oak heat. Those are same-week jobs. Tune-ups and audits book on the next route day.
We are a call-first repair company. Technicians carry solenoids, diaphragms, spray bodies, rotors, and nozzle trees so most Stone Oak repairs finish in one visit. You get a plain-language explanation of what failed and how to water the soil you actually have.
Photograph the controller program before any upgrade. Label the valve box once we find it. Those two habits prevent a lot of repeat Stone Oak calls after the next landscaper or freeze.
