Irrigation and Sprinkler in Arizona

Arizona has 491 irrigation and sprinkler companies listed in this directory, and every one of them confirms on its own website that it installs, repairs or maintains watering systems. They make up about a quarter of the 1,953 landscape companies we track across the state. The work runs from a single broken sprinkler head to a full new drip system, so the right company for you depends on the job and on how the business is set up to do it.

Irrigation work falls into a few kinds of job. Repairs cover leaks, broken heads, stuck or failed valves and damaged lines. Controller work means replacing or reprogramming a timer, often with a smart or Wi-Fi model. New installs lay out pipe, valves and emitters for a yard that has none, or for a landscape being rebuilt. Conversions swap spray heads for drip lines where plants no longer need broad coverage. Leak finding is a skill of its own, because a slow underground leak can be hard to locate without digging up half the yard.

Very few of these companies do irrigation alone. Of the 491, 389 also design and install landscapes and 347 offer ongoing maintenance. Hardscape and pavers appear on 320 of their websites, landscape design plans on 263, commercial and HOA service on 261, landscape lighting on 226 and tree care on 223. Artificial turf shows up on 207, outdoor kitchens and fire pits on 182, desert and xeriscape work on 120 and pools on 46. In practice your sprinkler repair may be handled by a maintenance crew, and a new drip system is often one line item inside a bigger landscape build.

That mix matters when you compare quotes. A dedicated irrigation outfit tends to concentrate on diagnosis and repair, while a design-build firm treats the system as part of a new layout. Neither approach is wrong, but you should know which one you are hiring. For a new system or a conversion, ask how the zones will be laid out, since lawn, shrubs and trees usually need separate valves and run times. Ask whether the quote includes a new controller or reuses your existing one, which valve and emitter products are planned, and whether trenching under existing walkways or patios is included.

Ask how leaks are guaranteed and how long the company stands behind its own fittings and connections. Find out what a repair visit includes, and whether the technician will run and check the rest of the system while on site. If you already have a maintenance contract, ask whether irrigation repairs are covered or billed separately, because agreements differ on this point.

Arizona licenses contractors through the Registrar of Contractors, and irrigation falls under its Hardscaping and Irrigation Systems classes: CR-21 covers residential and commercial work, R-21 is residential only and C-21 is commercial only. We matched 240 of the 491 companies, about half, to an active licence on the ROC posting list dated 7 October 2026, and 210 of them hold a 21-class licence. The rest could not be matched on the ROC list, which can happen when a business trades under a different name from the one on its licence. Before you sign, look the company up yourself in the ROC's free contractor search and confirm the class fits the job.

Thirteen cities have their own irrigation page. Phoenix has 118 companies, followed by Tucson with 50, Scottsdale with 34, Mesa with 31, Gilbert with 25, Chandler with 19, Peoria with 18, Queen Creek and Surprise with 16 each, Glendale with 15, Tempe with 13, and Prescott and Prescott Valley with 10 each. Smaller places have fewer options: Yuma, Flagstaff, El Mirage and Cave Creek each have 7, and many towns have only one or two, so it is worth asking companies based in a nearby city whether they travel to you.

Climate changes the questions you should ask. In the hot, dry low desert, including the Phoenix metro, Tucson and Yuma, ask how the watering schedule will be adjusted through the year and who makes those changes. In Flagstaff, Prescott and Prescott Valley, where winters bring freezes, ask whether the company drains or protects the system before cold weather and starts it back up in spring.

Common questions about irrigation and sprinkler in Arizona

What kind of irrigation work do Arizona companies handle?

The 491 irrigation and sprinkler companies in this directory list sprinkler and drip installation, repairs to leaks, heads, valves and lines, timer and controller replacement, leak finding and conversions from spray heads to drip. Some focus only on watering systems, but most bundle irrigation with other work: 389 also design and install landscapes and 347 offer recurring maintenance. Read each company's own description to see whether it handles the specific job you need.

Should I hire an irrigation specialist or my regular landscaper?

It depends on the job. A company that does nothing but irrigation usually concentrates on diagnosis, leak repair and controller work. A landscaper that also installs, as 389 of the 491 companies here do, can fold a new system into a larger project such as hardscape, which 320 of them list. For a leak nobody can find, a specialist is a sensible first call; for a new yard, one company handling both can keep pipe runs and planting in step.

How do I check an Arizona irrigation contractor's licence?

Search the company in the Registrar of Contractors' free contractor search and confirm the licence is active and in the right class. Irrigation falls under CR-21, R-21 or C-21. Across Arizona we matched 240 of 491 irrigation companies to an active licence on the ROC list dated 7 October 2026, and 210 of them hold a 21-class. A company that could not be matched on the ROC list may trade under another name, so ask it for its licence number.

What should a quote for a new drip or sprinkler system include?

A clear quote names the number of zones and what each one waters, the controller being installed or reused, the valve and emitter products, and whether trenching, boring under walkways and cleanup are included. It should also state how the company guarantees its own fittings against leaks. If you are converting spray heads to drip, ask whether capping old heads and removing unused lines is part of the job. With 389 of 491 companies also doing installs, compare at least two written quotes.

Can I find an irrigation company outside the big cities?

Yes, though the choice is thinner. Beyond the 13 cities with their own page, Yuma, Flagstaff, El Mirage and Cave Creek each have 7 irrigation companies listed, Maricopa, Avondale and Apache Junction have 6 each, and Buckeye and Goodyear have 5. Many smaller towns list only one or two, so look at companies in the nearest larger city as well and ask whether they cover your address before booking a visit.
