Water gushing, a spiked bill, or a soggy patch that won’t dry: Evergreen Sprinklers repairs every outdoor water leak in the Conejo Valley, licensed under CSLB #949420 (C36 – Plumbing). Outdoor water systems only; we do not repair roof leaks or interior plumbing.
Not sure where the water is going? That’s the detection half of the job, and we do it as standing work, not a favor: pinpointing outdoor leaks in irrigation lines, valves and manifolds, main service lines, and drainage — before anything gets dug up. Conejo Valley clay holds water and can carry it sideways, so the wet patch on the surface is often not where the leak actually is. When the ground does get opened, it’s one targeted spot, not a trench across your yard — and because we’re the same licensed C-36 crew that does the repair, “found it” and “fixed it” are one conversation instead of two contractors.
A water main or service line leak, the pipe running from the street-side meter to your house, is licensed plumbing work, and Evergreen Sprinklers is state-licensed under CSLB #949420, Classification C36, to repair it. These leaks often show up as a spike on your water bill, a wet or spongy patch of lawn with no obvious cause, or a drop in water pressure inside the house. Because the pipe runs underground beneath landscaping, driveways, or root systems, locating it takes a combination of listening equipment, pressure testing, and excavation limited to the affected section, not the whole yard. Once found, we repair or replace the damaged section and restore the landscaping around it, so your yard isn’t left torn up longer than necessary. Seeing these signs between your meter and home? Call (805) 390-7437 and we’ll take a look.
Finding an underground leak starts with the same questions a technician asks on any call: has your water bill spiked, is there a patch of yard that stays wet or unusually green, and can you hear running water when nothing is turned on? From there, we isolate the zone, shutting off irrigation valves one at a time or checking the main line separately, to narrow down whether the leak is in the sprinkler system or the water line itself. Acoustic listening devices, and pressure testing where needed, pinpoint the leak’s location within a small area before any digging starts, which keeps repair costs down and limits damage to lawns, roots, and hardscape. Most underground leaks are repaired quickly once scheduled, under the same CSLB license that covers our full irrigation and sprinkler work.
The most common signs: a water bill that jumps with no change in usage, a soggy patch of ground that doesn’t dry out between waterings, unusually green or fast-growing grass in one spot, a section of lawn that sinks or feels spongy underfoot, or the sound of running water near a wall or in the yard when everything is off. Cracked or lifted pavement near a buried line, and mineral or mold staining along a foundation, are less common but worth flagging too, particularly if they appear alongside a water bill increase. A musty smell near a slab or low spot in the yard can also point to water sitting somewhere it shouldn’t. Any one of these signs, especially combined with a bill spike, is worth calling about right away rather than waiting, since a small underground leak rarely stays small and can undermine soil, hardscape, and root systems the longer it runs unaddressed. Left long enough, a slow leak can also erode the base under a driveway, patio, or fence line, turning a modest repair into a much larger one.
Not always, and the distinction matters for how the repair is scoped. A sprinkler or drip-line leak is part of your irrigation system, usually a cracked lateral line, a broken head, or a failed valve, and is contained within the irrigation zones, so the rest of your household water supply is unaffected. There’s also a middle category: your irrigation system’s own main line, the trunk line running from the backflow device to the valve manifold before it splits into zones. A leak there is still an irrigation-system issue, not a household plumbing problem, but because it runs at full pressure before the valves it can waste more water and show up faster on your bill than a zone-level leak. A water main or service line leak is the pipe supplying your whole property, from the meter at the street to the house, and a failure there affects your household water supply, not just the lawn, which is why it tends to show up as a bill spike even when nothing outside looks obviously wrong. We service all three under the same CSLB C36 license: sprinkler and drip-system leak repair, irrigation main-line repair, and water main / service line repair, so you don’t need to find two different contractors depending on which line turns out to be affected, or juggle separate appointments and separate invoices for what may be one underlying problem traced back to a single source.
No. Evergreen Sprinklers is licensed and equipped for outdoor water systems: irrigation, sprinklers, underground yard leaks, and water main / service lines from the street to the house. Roof leaks, interior plumbing, and water heater work fall outside this license and outside our scope of work, so we won’t send a crew out for them, and we’d rather tell you that up front than waste your time on a visit we can’t act on. If you have a roof leak, a roofing contractor is the right call; for interior plumbing or a water heater issue, a general plumber licensed for indoor work is the better fit for that job. If you’re not sure which category your problem falls into, call us anyway; we can usually tell over the phone whether it’s an outdoor water-system issue we handle directly or something better routed elsewhere first.
Outdoor water-line leak repair, especially anything touching the water main or service line, is plumbing work, and California requires a C36 Plumbing license to perform it legally. Evergreen Sprinklers has held CSLB License #949420, Classification C36, since 2010, is bonded, and has served the Conejo Valley as a family-owned business since 1972. That track record means the same crew that installs and repairs your irrigation system is also licensed to repair the leak if it turns out to be on the water line rather than the sprinklers, so there’s no guessing which contractor to call first, no getting bounced between an irrigation company and a plumber, and no gap in accountability if the cause turns out to be different than it first appeared when you called. One licensed crew, one invoice, one point of contact from diagnosis through repair, backed by five decades of hands-on experience working underground on properties across these same neighborhoods we still proudly serve today.
Both. Finding the leak is the first half of every leak call — we locate the problem, show you what we found, and you decide on the fix. If you already know where the break is, we go straight to repair.
It depends on the system and what it takes to corner the leak. Tell us what you’re seeing and we’ll give you an honest read on scope before any work.
“I noticed our water bill spiked last month and had a random soggy patch near the side of the house. I called Evergreen Sprinklers based on a neighbor's recommendation, and they sent someone out the next day. The technician, Chris, found a cracked line hidden under the tree roots pretty quickly. He fixed it right then and there and even adjusted a few other heads that were spraying the fence. Super honest, fast work, and didn't try to upsell me on stuff I didn't need.”
