Sprinkler system installation in Raleigh, NC.

Not a one-size template dropped on the lawn

An install worth having begins on paper. We record where the sun falls, which way the ground drops, and what the soil is doing, then divide the yard into zones that each get heads suited to them and a sensible volume of water. On this ground that means consistent application rates within a zone and a staged run, so the water goes down rather than sideways.

Every new system on Raleigh Water gets the required RPZ backflow assembly installed and filed, and we’ll set you up with a smart controller so the system waters by weather, not by habit. Adding zones to an existing system counts too — we tie in cleanly without redoing what already works.

What drives the price of a new system, and what does not

Zone count drives most of the number. Every zone is a valve, a run of pipe, a share of the trenching and a set of heads, so a property that genuinely needs eight costs meaningfully more than one that needs five. What decides zone count is not the size of the lawn but how many different watering requirements the property has — full sun turf, shaded turf, beds and anything on a slope all want different amounts, and combining them means at least one is always wrong.

The second driver is what the pipe has to get through. An open lawn is quick. Mature root systems, hard surfaces to cross, and existing utilities to avoid all add real time, and on older Raleigh properties they usually all apply at once. What installs look like across Raleigh’s neighborhoods is its own page.

What does not drive the price, despite what you might expect, is the brand of head. The difference in parts cost between the major manufacturers across a whole system is small enough to be noise next to the labor. We fit Hunter, Rain Bird and Toro because they are serviceable and parts are available in ten years, not because one is dramatically cheaper.

We quote after measuring pressure and flow at the property. Supply varies more across Raleigh than people expect, and a layout designed on an assumed figure produces a system that works everywhere except the far corner — which is always the corner you notice.

The decisions you will live with for twenty years

Zoning is the one that matters most and the one people think about least. Separating beds from turf costs a little more in valves on the day and saves considerably more in water and replaced planting over the life of the system. Almost every retrofit complaint we deal with on newer properties traces back to a zone that was drawn before the landscaping existed.

Scheduling is next, and on Raleigh clay it is not optional. The ground accepts water at a fixed rate, and anything delivered faster runs across the surface to the street. So a system here should run in several short cycles with soak time between them rather than one long one. Same total volume, but it ends up in the root zone rather than in the gutter. We set that up before we leave rather than handing you a manual.

Head spacing is the decision you cannot fix later without digging. Head-to-head coverage means each head’s spray reaches its neighbors, and it looks like overkill until the first August, when a system spaced to save four heads shows a dry crescent at the edge of every zone. We space for the nozzles actually being fitted, not for a catalog figure.

The last one is planning for the yard you intend rather than the yard you have. If beds, trees or a patio are coming, leaving capacity at the manifold and a capped stub for a future zone is a five-minute decision at install and an expensive one to revisit. We will ask.

What an installation actually looks like from your side

A typical residential install in Raleigh is one to two days on site, and the great majority of that is trenching. Head and valve work goes quickly once the pipe is in the ground, which is why a property with difficult access can take twice as long as one of the same size with an open run.

Day one is usually layout and trenching. We mark the head positions and the pipe routes first and walk them with you before anything is cut, because the cheapest time to move a zone boundary is while it is still spray paint on the grass. Utilities get located before we start — that is not optional and it is not something to take anybody’s word for.

The trench itself closes over within a couple of weeks. We pull rather than dig where the ground allows it, keep the spoil on boards, and put the turf back as we go rather than leaving it in a heap until the end. The line stays visible for a season and then it does not.

The final hour is where most installs are let down. Every zone runs with you there, arcs get trimmed against what you actually want wet, and the controller is set for the month you are in rather than left on whatever came out of the box. You should finish the day able to change a schedule without ringing anyone, because the alternative is paying somebody to do it every April.

We also leave the as-built with you — valve locations, zone coverage and what is buried where. It costs us nothing and it means that in fifteen years, when something finally needs attention, whoever opens the box is not starting from a blank sheet the way we so often do on other people’s work.

That document is worth more than it sounds. A property with a known layout gets diagnosed in twenty minutes; a property without one can absorb an hour before anybody touches a tool, and you pay for that hour every single visit for the life of the system.
