What are the warning signs when hiring an irrigation contractor in Florida?

Check three things before an irrigation company starts digging: whether its plan ties new lines into your drinking-water supply, which DBPR treats differently from work behind an existing backflow preventer; whether it wants cash or the whole amount up front; and whether it asks you to pull the permit, which a DBPR bulletin lists among unlicensed activity warning signs.

Key facts

What should a written quote include before I pay anything?

Ask for a written sprinkler estimate that lists the water source, each zone with its head count and head type, the controller, any backflow preventer work and sod repair as separate line items, plus a completion date and price; the FTC says a written estimate should describe the work to be done, materials, completion date and price.

FDACS's consumer page on service contractors, read 14 October 2026, advises: "Ask for a written estimate and inspect the terms carefully before signing and agreeing to any offer." On a sprinkler job, the terms worth reading twice are the ones that decide what happens where the system meets your water line.

DBPR's What Requires a License page, read 14 October 2026, lists in its Needs a DBPR License column: "Perform plumbing work or irrigation installation that requires the contractor to connect lines to potable (drinking) water for compensation."

The same row's Does not need a DBPR License column reads: "Install or repair irrigation systems that have a backflow preventer connected to a potable (drinking) water supply regardless of compensation." When an estimate never says which side of that line your job sits on, have the company write it in before you sign.

Five gaps in a sprinkler estimate deserve a question before any money changes hands:

  1. A zone count left blank or described only as enough to cover the yard: how many zones, and which lawn or bed does each one water?
  2. Heads listed as one lump: how many rotors, sprays or drip lines go in each zone, and which model?
  3. An offer to leave out, bypass or take away the backflow preventer: who proposed it, and what does your water utility say about it?
  4. Trenching with no word about buried utility lines: who asks for the locate, and on what date?
  5. Sod, plants or pavers in a trench path: who restores them, and is that a line item?

Before a trench is cut, section 556.105(1)(a) of the 2026 Florida Statutes, read 14 October 2026, begins: "Not less than 2 full business days before beginning any excavation or demolition that is not beneath the waters of the state, and not less than 10 full business days before beginning any excavation or demolition that is beneath the waters of the state, an excavator shall provide the following information through the system:" Ask the company who gives that notice for your address, and put its date on the schedule.

The next section, 556.108, opens with "The notification requirements provided in s. 556.105(1) do not apply to:" and then lists exemptions. If a company tells you no notice is needed for your trenches, ask which listed exemption it relies on.

The FTC's guidance on hiring after weather emergencies, read 14 October 2026, says "Before you sign a contract, make sure it includes" and lists "an estimated start and completion date" and "a payment schedule" among the items. On a sprinkler contract, show the tie-in day and the day each zone is tested as dates of their own.

Post your request

Split an irrigation payment schedule by events you can see rather than by calendar dates: pipe, heads and controller delivered to your home; the locate notice given; trenching finished; the water-line tie-in and any backflow preventer fitted; and a walk-through where each zone runs while you watch. A payment tied to something visible is easier to check than one tied to a promise.

What payment requests are warning signs?

Treat a demand for cash, a request for the whole system's cost before the first trench, a request that you pull the permit yourself, or a contract listing only a P.O. box as reasons to wait; DBPR's 16 May 2025 bulletin names large upfront cash payments, permit refusals and P.O. boxes among its unlicensed activity warning signs.

DBPR's hurricane-season bulletin, posted 16 May 2025 and read 14 October 2026, says: "Florida homeowners and business owners should be aware of the following unlicensed activity warning signs:" Its list includes "Requests for large, upfront cash payments." and "Refusal to pull permits or requests for the homeowner to personally pull permits for a project." and "The use of P.O. boxes rather than physical addresses." Each item is a sign to look into, not a finding about any business.

FDACS gives a short rule of its own on the same page as its estimate advice: "Never agree to a cash-only deal." Ask for a payment method that leaves you a dated record naming the business.

Hold part of the money back until the end. The FTC home improvement page puts it directly, "Don’t pay the full amount for the project up front.", and tells readers never to make the last payment before the work is done and they are satisfied with it; on a sprinkler job, that means after every zone has run.

Broken pipes and tipped heads after a storm can bring a knock on your door. The FDACS page opens: "After a disaster you will frequently see “fly-by-night” contractors who take deposits before starting work or who take final payment before finishing the job."

The same FDACS page says "Be cautious of repair businesses or individuals who:" and its list includes "Solicit door-to-door," and "Claim they are from another county or state and are in the area solely to help disaster victims, or". Take the same written estimate from a visitor as from anyone else, and compare it before paying.

The FTC's storm-recovery guidance lists "Scammers claim they don’t need to be licensed to do the work." among the signs to recognize. If your job ties new lines into drinking water, compare that claim with the two DBPR entries quoted earlier.

  1. Payment for a new backflow preventer when the estimate says the old one stays: ask which is true, and get one answer in writing.
  2. A charge for a controller or rain sensor you never approved: ask for a written change order before it reaches your bill.
  3. The last payment requested before every zone has run with you watching: ask to schedule the walk-through first.
  4. A payee name that differs from the company on your estimate: ask who receives the money and whether the contract can name them.

A request on this list is a reason to hold your payment and ask, which is different from proof that a business has acted wrongly.

What should I do if the work stops?

Start by dating photographs of open trenches, exposed pipe, missing heads and the controller, then gather your contract and receipts and write to the company; DBPR handles complaints about the professions it regulates, with administrative discipline, and FDACS takes complaints about regulated or non-regulated businesses.

Write down the last day anyone worked, which zones remain unfinished, whether the water to the system or the house was shut off at the tie-in, and any reason you were given.

When a sprinkler job stalls, the FTC's home improvement page points first to the contractor itself: try to sort it out directly, put whatever was said by phone into a letter sent by certified mail with a return receipt requested, and hold on to your notes and copies of every letter and document.

DBPR's complaint page, read 14 October 2026, states: "The professions and businesses regulated by the Department of Business and Professional Regulation and the disciplinary action that may be taken is administrative in nature, e.g., reprimand, fine, restriction of practice, remedial education, administrative cost, probation, license suspension or license revocation." Getting money back or ending the contract is a question for a Florida attorney.

In Broward County, the Report a Complaint directory, last updated 19 August 2026, sets out what its Building Code Division can and cannot do: "The Building Code Division can initiate administrative disciplinary action against the license of a Broward County contractor who has violated a law, an ordinance or the Florida Building Code. They cannot make a contractor perform corrective work or pay damages, and have no authority to impose the settlement of a contract or other civil damages. Complaints must be submitted in writing." Before filing there, ask whether a sprinkler job at your address is one the division handles.

What should my request include?

Describe the irrigation job once, with photographs of the water meter, any backflow preventer, the controller and each lawn or bed area: which areas need water, whether the plan adds a connection to your drinking-water line, where trenches would cross walkways or driveways, and who puts the sod back afterwards.

Contact details stay hidden until the homeowner picks a contractor and they confirm the connection.

Where can I look up public records myself?

Check, only if you want to, two dated public records: DBPR's Online Services search for a company whose quote adds a connection to your drinking-water line, and the Division of Corporations index for the name on your contract; a result shows what an agency listed on the day you searched, not how well anyone installs sprinklers.

DBPR describes its Online Services search as giving information about applicants and licensed individuals in the professions and businesses the department regulates. Type in the company name printed on the sprinkler estimate and write the search date beside whatever comes back.

DBPR's construction industry page, read 14 October 2026, lists the plumbing contractor category as CF and RF and says: "A plumbing contractor may install, maintain, repair, alter, extend, or design the following without obtaining any additional local regulatory license, certificate, or registration:" Its list includes "irrigation systems; or". The same page has separate forms for a Certified Irrigation Specialty Contractor, a distinct category.

Florida's Division of Corporations calls itself "the State of Florida's official business entity index and commercial activity website." Run the company name through its records search and set the result beside the payee named on your receipts.

Keep each dated result with your zone sketch and photographs. A record tells you what an office showed that day; your contract tells you which zones, heads and connections this company promised.
