Lawn sprinklers and garden irrigation in Forest Hill
Forest Hill is one of the neighbourhoods where we do the most work, and it is not a place where a standard subdivision layout fits. These are mature properties with substantial trees, established garden beds, stone walkways and often heritage character worth protecting during installation. Pro Green Irrigation has been designing and installing irrigation and landscape lighting for Forest Hill properties since 1999.
What does a lawn sprinkler system cost in Forest Hill?
A typical subdivision lot with a 40 to 60 foot frontage and 100 to 150 foot depth is generally in the range of $3,900 to $4,900 in Forest Hill. That figure moves with the property — the landscaping, garden detail, water supply and actual layout all change the design. For larger properties a site visit is needed to price accurately, and we give you a written quote after walking the property with you rather than a number over the phone.
Why do properties in Forest Hill need a custom design?
Forest Hill lots are generally deep and heavily planted, with mature canopy over much of the turf and extensive beds along the perimeter. That combination — shade, root competition and deep planting — means one blanket schedule will fail somewhere on the property. Turf under a mature maple needs different water from an open sunny stretch by the drive, and the beds need different water again.
We work throughout Forest Hill and the streets around it — Forest Hill South and North, the Upper Village, Cedarvale and across toward Casa Loma and Chaplin Estates.
What is the water supply and pressure like in Forest Hill?
City of Toronto supply with generally reliable pressure, though some Forest Hill homes still have older service lines that reduce available flow more than the age of the house would suggest. We measure static pressure and flow before design. Backflow prevention is required and included.
How often should you water a lawn in Forest Hill?
Forest Hill runs largely on clay with a good depth of established topsoil from decades of garden care. Clay holds moisture well but accepts it slowly, so scheduling favours shorter, repeated cycles — particularly on the sloped properties toward the ravine.
Do you need a backflow preventer in Forest Hill?
Backflow prevention is required on any connection to the City of Toronto potable supply. On properties with this much planting, a weather-based controller pays for itself quickly by skipping cycles after rain rather than watering established beds that do not need it.
How is a sprinkler system installed?
Forest Hill systems typically run more zones than the lot size suggests, because shade, sun, slope and beds all need separating. Installation is done trenchlessly and hand-worked around mature root systems, stone and established planting — protecting what is already there is most of the skill on a property like this.
- Trenchless installation. Pipe is pulled beneath the turf rather than dug in, so an established lawn is walkable the same day.
- Contractor-grade components. Hunter and Rain Bird heads, valves and controllers — the same parts we have to come back and service.
- Separate zones for lawn and beds. Turf gets a shorter, heavier cycle; garden beds get slow drip at the roots.
- Backflow prevention included. Required for connection to the municipal supply, fitted as part of the installation.
- Our own crews. We never sub-contract — the people on your property are on our payroll.
- Five-year parts and labour warranty* on every system we install.
Do you install landscape lighting in Forest Hill?
Forest Hill is close to ideal for low-voltage landscape lighting. Mature specimen trees uplit from below, stone facades washed with light, and path lighting along long front walks change the property completely after dark. We install Vista and other contractor-grade fixtures, designed with you on site, and we routinely do lighting and irrigation together so the property is only opened up once.
When should a system be started up and winterised?
Spring start-ups from April, fall blow-outs from late September. Properties with high zone counts take longer to winterise, so Forest Hill clients are best booking early in the fall.
A spring start-up means charging the system, checking every head, adjusting spray patterns and programming the controller for the season. A fall blow-out means clearing the water out of the lines with compressed air so nothing freezes and splits over winter. In this climate winterisation is not optional — water left in a line will crack the pipe or the fittings.

Forest Hill irrigation questions
The questions homeowners in Forest Hill ask us most often before booking a quote.
Can you install irrigation without damaging mature trees and gardens?
That is the core of the work here. We pull pipe beneath the turf rather than trenching, and hand-work around mature root systems, stone and established beds. Protecting decades-old planting is the point — a system that scars the garden it was meant to keep alive has failed.
How many zones does a Forest Hill property need?
More than the square footage suggests. Shaded turf, open turf, sloped areas and deep beds all want different water, so they need separating rather than averaging. Ten or more zones is common on a substantial Forest Hill property.
Do you also do landscape lighting?
Yes, and Forest Hill is one of the areas where we do the most of it. Mature trees, stone and long walkways respond dramatically to well-designed low-voltage lighting. Doing it alongside the irrigation means the property is disturbed once rather than twice.
What does a system cost for a property like this?
Forest Hill properties are generally above the standard subdivision range of $3,900 to $4,900, because they need more zones and extensive garden drip. A site visit is genuinely necessary here — quoting a property of this type from a description would not be honest.
Can you water the garden beds properly, not just the lawn?
Yes. Beds run on drip line, on their own zones, so shrubs and perennials get a slow deep soak at the roots rather than being sprayed across the foliage.
Do you service existing systems in Forest Hill?
Yes — service, repairs, spring start-ups and fall winterisation on existing systems regardless of the original installer.
