How to Vet and Hire an Irrigation Contractor in DFW

I'm Brandon Surratt — TCEQ Licensed Irrigator (LI0023963) and Certified Landscape Irrigation Auditor through Texas A&M AgriLife. I run Better Earth Solutions in Dallas-Fort Worth and I get called to clean up other contractors' work often enough that I have opinions on how homeowners should pick one in the first place.

This is a plain-English guide to vetting an irrigation contractor in DFW. License lookup, the questions to ask, what real credentials actually mean, and the things I've personally seen go wrong on cleanup calls.

What you'll learn:

• The actual TCEQ license lookup process (URL and what to search for)
• The 4-5 questions every homeowner should ask before hiring
• Why insurance matters more than the license itself
• What credentials are real versus what's marketing
• How to read a $500 vs $1,200 vs $2,800 quote spread
• Why "just a guy with a truck" isn't always wrong, and when it is
• Why everything needs to be in writing

Red Flags From Real Cleanup Calls

I get called to fix other people's irrigation work. Here are the things I've actually seen, in order of how often they show up.

Valve installed backwards, no warranty

I went to a job once where the previous installer put a control valve in backwards. It worked for a while, then failed in a way that was obvious once I looked at it. The original guy refused to warranty the work. The homeowner ate the cost.

This is the cleanest red flag in the trade — someone who refuses to warranty their own work is telling you something. Not "we'll consider it case by case." A flat refusal.

Rotors and spray heads on the same zone

Mixed-head zones are everywhere in DFW. A spray head puts out roughly 1.5 inches of water per hour. A rotor puts out about 0.5 in/hr. If they're on the same zone, one of them is getting the wrong amount of water — there's no runtime that works for both.

Honest note: this is more often a homeowner DIY mistake than a contractor mistake. But I've also seen it on installs that were definitely paid for. Either way, it's a signal that the system was never designed properly.

Frankenstein funny-pipe runs

Funny pipe is the flexible black tubing that connects a sprinkler head to the lateral line. It's supposed to be short — a foot or two of give so the head can move without breaking the lateral connection.

I've seen runs that are 20+ feet of funny pipe daisy-chained together to reach a head, weird joints, garden hose used as substitute, all kinds of patchwork. That's a sign of someone working around a problem instead of fixing it. Cheap short-term, expensive long-term.

TCEQ License Lookup (Do This First)

In Texas, irrigation work is regulated by the Texas Commission on Environmental Quality (TCEQ). Anyone installing or repairing an irrigation system on someone else's property is supposed to be licensed.

You can verify a contractor's license yourself in about a minute.

How to do it

1. Go to tceq.texas.gov/licensing
2. Click on Individual Search (or the equivalent license-search link)
3. Search by the contractor's name or license number
4. Verify it's active and look at the license type — for irrigation work you want Licensed Irrigator (LI)

If a contractor can't or won't give you their license number, that's the answer to whether they have one.

For reference, my license is LI0023963, on file under Brandon J Surratt.

Why the License Matters (The Honest Answer)

Here's the honest truth: I get asked why TCEQ licensing matters for the homeowner, and the most accurate answer is because of what tends to come with it.

Unlicensed contractors aren't all bad at the work. Some of them are knowledgeable people just starting out who haven't bothered to get licensed yet. But there are real things that almost always come with being unlicensed:

• They probably aren't insured. This is the bigger issue. If an unlicensed installer hits a buried gas line, water main, or fiber optic cable, you (the homeowner) can be on the hook. Insurance is the actual protection.
• They probably don't know the backflow rules. TCEQ rules around backflow prevention exist to protect the public water supply. The licensing process forces you to learn them.
• You probably can't reach them in two years for a warranty claim. Licensed contractors have an address on file with the state, a license to protect, and a reason to stay reachable.

So the license isn't magic. The license is a proxy for "this person has insurance, knows the code, and can be found later." Those three things are what actually protect you.

The Short List of Questions to Ask

Before signing anything, ask:

1. Are you licensed? (Get the number, verify it on the TCEQ site.)
2. Are you insured? (Ask for a Certificate of Insurance. They should be able to send one. If they can't, they don't have one.)
3. Are you using all new equipment? (Specifically: are the heads, valves, and major components new — or pulled from another job?)
4. What kind of warranty do you provide? (And is it in writing?)

That's the short list. Add a fifth depending on context:

5. For larger jobs: Have you done a job like this in DFW recently I can drive past or a customer I can call?

The four core questions will catch most of what matters. A contractor who answers all four directly and then volunteers their license number and COI before you finish asking is signaling the right things.

Insurance and Warranty Verification

Insurance — the document name

The thing you're asking for is a Certificate of Insurance (COI). It's a one-page document the contractor's insurance carrier issues that lists their policy types, coverage amounts, and effective dates. A real contractor can produce this in 24 hours by emailing their agent. Some can produce it on the spot.

If the answer is "yeah I'm insured, just trust me," that's the same answer as "no."

Warranty — what to look for in writing

A written warranty policy should specify:

• What's covered — labor, parts, both?
• What's excluded — common exclusions: damage from freezing, vandalism, lightning strikes on the controller
• How long it lasts — 30 days is short, 1 year is standard, multi-year on parts is generous
• What you do to make a claim — call them, email, etc.

A verbal "yeah we stand behind our work" is worth approximately nothing once a problem actually shows up.

How to Read a $500 / $1,200 / $2,800 Quote Spread

Honest answer: without knowing what each quote actually covers and what warranty comes with it, you can't read the spread. Anyone telling you "the middle one is always right" or "throw out the high and low" is making it up.

What changes price legitimately:

• Scope. A $500 valve replacement quote might be just the valve. A $2,800 quote might include re-piping the manifold because the manifold is corroded and the cheap quote is going to fail in eight months.
• Equipment grade. Cheap heads versus contractor-grade. Contractor-grade brass valves versus disposable plastic.
• Warranty length. A 30-day warranty is cheap to provide. A 1-year warranty is real.
• Labor and trip charges. Some contractors bake travel into the quote, some itemize it.
• Diagnostics. Was a real diagnosis done before the quote, or is the quote a guess?

What's NOT a legitimate price difference: rip-offs. Some expensive quotes are rip-offs. Some cheap quotes are rip-offs (low entry price, then "discovered" problems double the bill mid-job). Price alone doesn't sort this out — only the scope, warranty terms, and contractor reputation do.

If you can't compare scope between quotes, ask each contractor to itemize. A real contractor will. A flaky one will resist.

What Counts as a Real Credential in DFW Irrigation

There's a lot of credential inflation in this trade. Here's what actually means something and what doesn't.

Real, third-party-administered credentials

• TCEQ Licensed Irrigator (LI). State of Texas. Required to legally do irrigation work for hire on someone else's property. Exam, continuing education, license number you can verify online. (Mine: LI0023963.)
• Certified Landscape Irrigation Auditor — Texas A&M AgriLife. This is the one I wish more people asked about. The certification is administered through the Texas A&M AgriLife Extension School of Irrigation. EPA's WaterSense program lists certified auditors in their Find a Pro directory. Auditors are trained to use catch-can methodology to measure precipitation rate (PR) and distribution uniformity (DULQ) — actual numbers from your specific system. Rare in DFW.
• Texas Department of Agriculture Commercial Pesticide Applicator. State-issued. Required for anyone applying pesticides commercially. (Mine: 0947069.)
• NTMWD Green Pro Certification. North Texas Municipal Water District program. Multi-day class on water conservation in the NTMWD service area. The honest framing: this isn't a competency exam — it's a signal that the contractor cared enough to spend several days getting trained on local water issues. Mine is pending official directory listing.

What's NOT a third-party certification

• "Certified Rachio Pro." This is a brand affiliation program from Rachio (the smart controller manufacturer). It doesn't involve an independent exam or competency test — it's a relationship with Rachio. Useful as a signal that an installer knows Rachio specifically, but don't weight it like a third-party credential. I list myself as a Rachio installer in some places on the site, but I'd never put it in a credentials list alongside TCEQ licensing or the WaterSense auditor cert. Those are real.
• Most "certified by [manufacturer]" titles. Same logic — it's brand training, not third-party verification.

What to actually look for

When a contractor lists credentials, the test is: can a regulator or independent body actually verify it, and is there a real exam or qualification process behind it? TCEQ license = yes. Texas A&M AgriLife auditor = yes. Manufacturer "certifications" = usually no.

The Valve-Backwards Job

The cleanest example I have of why warranty matters in writing: I went out to a job where the previous installer had put a control valve in backwards. The system worked at first because water still moved through it, but the valve seat was being abused in a way it wasn't designed for. Eventually it failed.

The homeowner called the original installer. He refused to warranty the work. There was nothing in writing. The homeowner had no recourse — even though the failure was caused by an obvious installation error.

The other version of this same problem isn't even a single dramatic failure. It's the slow burn: chronic overwatering and wasted water from systems that were never set up right. I see months and months of overwatering on systems where the original installer never tuned the controller, never set seasonal schedules, never explained to the homeowner what they were looking at. The system "works" — it puts out water — but it's costing the homeowner hundreds extra per year and growing shallow-rooted grass that fails the first time it's stressed.

The fix in both cases is the same: make the contractor put the install in writing, including a warranty period during which they'll come back and tune the system if it's not performing.

"Just a Guy With a Truck" vs Licensed Irrigator

I'll be honest — not every guy-with-a-truck operation is bad. Some are knowledgeable people that are just starting out and haven't gotten licensed yet. They might do solid work.

But here's what you're trading off:

• No business insurance. This is the biggest one. If they hit a buried line, damage your foundation drainage, or injure themselves on your property, you can be the one paying. Homeowner insurance is not designed to cover contractor mistakes.
• No certainty they'll be in business next year. If your warranty period is one year and the contractor folds in six months, the warranty is worth nothing.
• No regulatory accountability. A licensed contractor has a license to protect. An unlicensed one doesn't have anything to lose if a job goes sideways and the homeowner complains.

Sometimes hiring the guy-with-a-truck is the right call — small repair, low stakes, clear scope, you've worked with them before. For new installs, mainline work, controller programming, anything involving the backflow, or anything you want to last 10+ years, hire someone licensed and insured.

Get It in Writing — Always

Every repair should be in writing before work starts. The write-up needs to spell out:

• What's being repaired or installed
• How much it costs
• How long it's going to take
• What the warranty is — duration, coverage, exclusions

If a contractor refuses or hesitates to put any of that in writing, walk away. The cost of waiting one more day to get a written quote is much smaller than the cost of arguing about scope and warranty after the work is done.

Without it in writing, you're just leaving everything ambiguous for later — and that's how you end up in a fighting match with someone who's already cashed your check.

If you want a contractor who will give you all of the above before you commit — license number on the quote, COI on request, written scope and warranty, real credentials you can verify — call (469) 209-4110 or book online.
