How to Grow Your Landscaping Business by Adding Irrigation Services

Why does irrigation outperform mowing on profit margin?

Routine maintenance - mowing, edging, blowing - carries 25%–35% gross margins, according to financial modeling published by Sheets.Market. Irrigation installs carry 40%–60% gross margins on the same customer's property.

Conserva Irrigation, which has franchised the irrigation bolt-on model across dozens of markets, puts it plainly: irrigation services have higher profit margins than typical landscaping jobs like mowing or trimming, and irrigation customers usually sign ongoing maintenance contracts. That recurring contract revenue is what smooths out the seasonal cash flow roller coaster that kills landscaping businesses every January.

If you want to understand how service agreements work in this context, the playbook we wrote on growing your landscaping business with service agreements runs the math on annual contract value versus one-off job revenue.

What does an irrigation install actually pay?

According to Angi's 2026 pricing data, a residential sprinkler system costs homeowners about $2,541 on average, with a range of $1,637 to $3,583. Scott McLeod, owner of McLeod Landscaping with over 30 years in the field, pegs the national average at around $3,600 for a quarter-acre yard, which is the median U.S. lot size.

Your Last Call Irrigation and Landscaping breaks it down by zone count: a typical home system requires 5–7 zones and runs $3,500–$6,500 installed. One-acre and larger properties land between $6,000–$10,000. Contractors typically price by zone at $500–$1,000 per zone rather than by square footage - that is the industry standard for quoting and it protects your margin when soil conditions get complicated.

McLeod also cites Forbes and NAR data showing homeowners see an average 86% ROI on a sprinkler system. That number belongs in every estimate you send.

How cheap are irrigation leads compared to other landscaping services?

Evergrow Marketing has published Google Ads benchmarks for the landscaping industry for five consecutive years. In their 2025 report, they analyzed 61 landscaping accounts spending a combined $225,000 in 2024 and found the average landscaping cost-per-lead was $87.80 at a $3.65 average cost-per-click.

Irrigation breaks that benchmark wide open. Evergrow found irrigation leads average $43.17 - less than half the cost of a hardscaping lead at $153.27. The conversion rate for irrigation searches hit 6.24%, which Evergrow attributes to high intent: most people do not search for sprinkler repair because they are curious. They search because their system is broken and the grass is dying.

For comparison, WordStream's 2024 data shows home services PPC conversion rates average 7.33% with a cost-per-click averaging $6.96. Irrigation sits comfortably inside that range at a fraction of the cost-per-lead.

When should you spend more on irrigation ads?

Seasonality matters more for irrigation than almost any other landscaping service. Evergrow's historical data shows landscaping CPL swings dramatically: around $50 per lead in spring, nearly $100 in summer, and over $200 in winter.

For irrigation specifically, Evergrow advises clients to increase ad spend hard in March, April, September, and October - spring startups and fall winterization blowouts. Search volume is extremely high during those windows and your competition may not be ready. If your market has a population under 100,000, Evergrow recommends a cap of $300 per month ($10 per day) during off-peak periods, then scaling up aggressively during those four core months.

The same seasonal logic applies to how you structure your service agreements. Locking customers into annual irrigation maintenance contracts during spring startup - when they are already spending money - is how you build the recurring revenue base. The pest control recurring revenue model uses the exact same seasonal hook to convert one-time customers into annual contract clients.

How do you convert your existing landscaping clients into irrigation customers?

This is the highest-ROI move on the entire board. The Sheets.Market financial model illustrates it clearly: if you have 180 residential maintenance clients at $100 per month and convert just 5% annually to an irrigation install averaging $5,000, that is 9 projects adding $45,000 in revenue with zero client acquisition cost.

HubSpot data confirms that referral and existing-customer leads convert 71% faster and at 71% higher rates than cold leads. Your mowing clients already trust you. They already let your crew on their property every week. That trust is worth money - stop leaving it on the ground.

Jobber recommends using email campaigns to tell existing clients when you expand services. That is the cheapest irrigation marketing channel available to you. A single email blast to 180 clients announcing spring irrigation startups costs almost nothing and can book your crew for two weeks.

If you need a system for managing client communication at scale without hiring an office manager, the AI receptionist system prompt guide for contractors walks through how to automate intake and follow-up for exactly this kind of outbound campaign.

What does the Google Ads budget actually look like?

Here is the math on a realistic irrigation PPC campaign:

If you spend $500 per month on irrigation-specific Google Ads during peak season, you are buying roughly 11–12 leads at $43 each. At a 6.24% conversion rate from click to lead and a 17% close rate from lead to signed job, you are closing 1–2 installs per month at $3,500–$6,500 each. That is a 6x–13x return on ad spend before you factor in maintenance contract upsells.

For comparison, we have seen this same ROI pattern across other service expansion plays - including the grow your lawn care business model and increasing average job ticket through upsell services. Irrigation is one of the cleaner examples of the math working in your favor from day one.

Do you need a special license to offer irrigation services?

Yes, in most states. The EPA's WaterSense program advises homeowners to confirm that any contractor designing, installing, or maintaining irrigation systems is licensed and bonded. Licensing requirements vary by state - many require separate irrigation contractor credentials distinct from a general landscaping license.

Before you spend a dollar on ads, call your state contractor licensing board and find out exactly what certifications apply in your market. In some states you can add irrigation under your existing landscape contractor license. In others, you need a separate exam and permit. Getting caught unlicensed on an irrigation install can cost you more than the job paid.

Evergrow Marketing's client base includes operators who have narrowed their focus entirely - running landscaping businesses that only do sprinkler repair, or only handle drainage work like French drains and channel drains. Specialization within the niche is a legitimate business model.

This mirrors what we see in other trade specializations, like electricians who focus purely on EV charger installations or plumbers who build a business around water filtration services. A focused service line is easier to market and easier to staff.

How big is the irrigation market opportunity?

IBISWorld's Landscaping Services Industry Report, cited by Jobber, puts the U.S. landscaping industry at $153 billion in market size as of 2024. The lawn care sector has expanded by more than 8.2% annually over three consecutive years.

Irrigation sits inside that growth curve and benefits from a separate tailwind: water conservation awareness is driving homeowners toward smart irrigation systems that use sensors and timers to cut water bills. That is a premium product conversation that shifts your average ticket upward without adding crew time proportionally.

If you want to see how other contractor trades are using service expansion to capture premium-tier work, the HVAC heat pump installation opportunity and electrical panel upgrade growth model follow the same pattern: one new service, same customer base, meaningfully higher margins.

Frequently Asked Questions

Start with one campaign this March

Pull your existing client list, segment out the residential maintenance accounts, and send one email announcing spring irrigation startup service before the end of February. Then set up a Google Ads campaign targeting irrigation repair and sprinkler installation keywords with a $300–$500 monthly budget and let Evergrow's benchmarks tell you what to expect. At $43 per lead and a 17% close rate, the math is hard to argue with - and the margins are twice what you are making on mowing.
