What to write on an irrigation contractor estimate
An irrigation estimate should give the number of zones, the head and drip types, the controller model and backflow device, and say who restores the lawn after trenching.
Materials and products are $770.00 of this $4,240.00 estimate (18%), so say how long those prices hold: supplier prices can move before the job starts.
Sprinkler installations are priced per zone, while service work such as spring start-ups, winterizing and head repairs is billed per visit plus parts.
Assumptions behind each line
Write these next to the 8 lines so the customer sees what the $4,240.00 depends on.
- Irrigation design and head layout: 1 project, $150.00.
- Spray zone installation, lawn: 3 zone, $2,550.00.
- Drip zone installation, planting beds: 1 zone, $650.00.
- Pressure vacuum breaker backflow preventer, 1 in: 1 each at $325.00 ($325.00); another grade or brand changes this line.
- Smart Wi-Fi controller, 6-station: 1 each at $220.00 ($220.00); another grade or brand changes this line.
- Rain sensor: 1 each at $45.00 ($45.00); another grade or brand changes this line.
- Irrigation permit and backflow test: a flat $120.00.
- Sod patching over trenches: 120 sq ft at $1.50 ($180.00); another grade or brand changes this line.
Changes, overruns and change orders
If the customer adds work, put it on a signed change order first. Pricing the extra in zone keeps it comparable with the $4,240.00 you estimated.
A 10% rise in material prices would add $77.00 to this job, which is why many irrigation contractors limit how long an estimate stays valid.
Tips from irrigation work billing
- List each zone with what it waters, such as front lawn spray or side bed drip, so when a zone fails later the customer and your technician know which valve to look at first.
- Record the backflow device's make, size and serial number and the date it was tested, because water utilities that require periodic backflow testing ask for exactly that information.
- Price spring start-up and fall winterization as separate visit lines and note how the lines were drained or blown out, since cracked fittings found in spring get traced back to the winterizing visit.
- Put trench restoration, such as sod, mulch or boring under a sidewalk, on its own line so the customer sees what the lawn repair cost apart from the system itself.

Frequently asked questions
How do I write an irrigation contractor estimate?
Describe the job (Install a four-zone sprinkler system for a front lawn and planting beds, with drip in the beds and a smart controller), list each line with an estimated quantity and rate, total it ($4,240.00 in the sample), state how long it is valid and what it assumes, then send it as a PDF for approval.
Is an irrigation contractor estimate binding?
An estimate is a forecast, not a fixed price, so the final invoice can differ when the work or materials change. Rules vary by country and state; to stay safe, get written approval before billing noticeably more than the $4,240.00 you estimated.
How long should an irrigation contractor estimate be valid?
Thirty days is common and is what this template uses. With 18% of the price in materials, a shorter validity protects you if supplier prices rise.
