Water where the lawn needs it. Nowhere else.
Sprinkler and drip systems for Ottawa homes — installed, repaired, opened in spring and blown out before the frost.
Free estimates. No charge to look at a system that isn't behaving.
It starts at the house
A backflow preventer sits between your drinking water and the lawn, so nothing that touches the ground can ever run back up the line.
The mainline runs deep
Buried below the frost line, then sleeved where it crosses the foundation. That depth is the difference between a system that survives an Ottawa winter and one that splits in February.
Valves split the yard into zones
Each zone runs on its own so the pressure stays where it belongs. Get the zoning wrong and every head on the property waters weakly at the same time.
Heads come up only when their zone runs
The rest of the time they sit flush with the turf. Nothing to mow around, nothing to trip on, nothing sitting in the middle of the yard.
Set it in May. Forget it until October.
We program the controller for your soil and sun, then come back to blow the lines out before the first hard frost.
What we do
Six jobs, and most Ottawa yards need four of them.
We install new systems and take over ones somebody else put in. If you inherited a system with the house and have no idea what half of it does, that's a normal call for us.
We walk the property, measure your water pressure at the tap, and lay out heads so the spray patterns overlap. Overlap is the whole game — a head that just reaches the next head is the reason lawns get brown rings.
- Pressure and flow test before anything is quoted
- Zone plan you get to keep, marked with head types and depths
- Trenched and pulled lines, backfilled and rolled so the lawn knits back
- Controller programmed and every zone tested with you standing there
Spraying a garden bed wastes most of the water on mulch and leaves. Drip tubing puts it at the root, under the mulch, where it soaks in instead of evaporating off a hot afternoon.
- Runs on its own zone with its own schedule — beds want longer and less often than turf
- Pressure regulator and filter so emitters don't clog
- Emitters sized per plant, added to as the bed fills in
Most "my sprinkler is broken" calls turn out to be one of five things: a head clipped by a mower, a nozzle plugged with grit, a cracked lateral, a solenoid that stopped opening, or a controller that got reprogrammed by a power cut.
- Zone-by-zone run test to find what is actually failing
- Head replacement, nozzle changes and arc adjustment
- Line locating and repair with minimal digging
- Valve, solenoid and wiring faults
Opening a system is not just turning the water back on. Charge it too fast and you can blow a fitting you won't find until the lawn goes soggy in July.
- Slow pressurization and a leak check at the backflow
- Every zone run, every head checked for arc, reach and level
- Nozzles cleaned, sunken heads reset to grade
- Controller reset for spring watering, then adjusted again in July heat
Water left in a lateral expands when it freezes and splits the pipe from the inside. You won't know until spring, when the zone comes on and the lawn turns into a fountain.
- Compressed air pushed through zone by zone until the heads run dry
- Regulated pressure — too much air damages seals as surely as ice does
- Backflow drained and isolated, controller set to off or rain mode
- Book by late September; the calendar fills before the first hard frost
Bought a house with a system nobody explained? We map what is in the ground, label the zones, and hand you a page that says which zone waters what.
- Full system audit with a written zone map
- Smart controllers that skip a cycle when it has already rained
- Rain sensor and moisture sensor add-ons
- Ten minutes at the end showing you how to run it yourself
The Ottawa irrigation year
A short season, and the two ends of it matter most.
Roughly seven months of running time between the last frost and the first hard one. Miss the blowout and you spend the following spring paying for repairs instead of watering.

How big a system does your yard actually need?
Move the slider to roughly the lawn area you want covered. This gives you the shape of the job — heads, zones and a typical range — before anyone comes out.
A typical Ottawa suburban lot has roughly 2,000–5,000 sq ft of lawn once you take out the house, driveway and beds.
How we work
Small operation. You deal with the person doing the work.
We measure pressure, walk the yard and give you a written price that does not move once the trencher shows up.
Marked with what each zone waters and how deep the lines run, so the next person who digs a fence post knows what is down there.
Call or text 343-596-5673 in July when a head gets clipped and you get the same person who installed it.
Where we work
Ottawa and the surrounding communities.
If you are just outside this list, call anyway — if we are already out that way for another job we can usually fit you in the same trip.

Common questions
Things people ask before they call.
When does my system need to be blown out in Ottawa?
Aim for October. You want it done after the lawn stops needing water and before the ground takes its first hard freeze. Booking opens in late September and the last two weeks of October are always the crush.
Do you work on systems you didn't install?
Yes, most of our repair work is on other people's systems. Bring us in for a startup and we will tell you honestly what shape it is in.
Part of my lawn stays brown. Is that a repair or a design problem?
Either. A single dry patch is usually a plugged nozzle or a head knocked out of arc. A long dry stripe between two heads usually means they were spaced too far apart to overlap, which is a layout fix, not a part swap.
Will installing a system wreck my lawn?
The lines are pulled or trenched narrow and the turf goes back over top. You will see the runs for a couple of weeks and by the second mow most people cannot find them.
Do I need a backflow preventer?
Yes. Any irrigation system tied into municipal water needs backflow protection, and it needs to be the right device installed at the right height. We handle it as part of the install.
Can I run it from my phone?
With a smart controller, yes — and it will skip a cycle when it has already rained, which is where the water savings actually come from. We can add one to an existing system without touching what is in the ground.
