Best Commercial Irrigation Companies in Houston

The best commercial irrigation companies in Houston hold a TCEQ irrigator license, test backflow assemblies, check every zone and report what they find in writing. Lawn Management Company, Monarch, Yellowstone, U.S. Lawns, Southwest Irrigation and Houston Commercial Landscaping all offer it. Landscapes USA publishes this guide and is listed last.

How did we choose and score these companies?

Plain disclosure first: Landscapes USA wrote this page and is one of the companies on it. That is why it sits last, and why every other entry is described only from that company’s own website, read in October 2026. Nobody paid to be included.

The list is alphabetical with the publisher last. It is not a ranking, because a fair ranking would need data no outsider has, like how fast each crew really fixes a broken lateral on an August Saturday. What we can check is what each company says it does, against six criteria:

1. Commercial focus. Does the site speak to property managers and HOA boards, or mostly to homeowners?
2. A published irrigator license number. Texas requires irrigation advertising to show it as “LI” plus digits. A number you can look up beats the word “licensed”.
3. Breadth of work. Installation, repair, inspection, upgrades, seasonal service.
4. Backflow testing done in-house by a licensed tester.
5. Water management. Smart controllers, rain sensors, seasonal programming.
6. Reporting. Something in writing after an inspection, for when an owner or board asks what they are paying for.

None of these is pass or fail. A company that does not print its license number may well hold one, so ask, then check it on the TCEQ license search.

What should a commercial irrigation company in Houston actually do for you?

On an office park, retail center or HOA common area, irrigation is often dozens of zones, several controllers, a backflow assembly or two, and a water bill someone above you reads every month. A good contractor covers four jobs.

Run every zone, not just the one that was reported

A wet check means turning each zone on and walking it while it runs. It is the only way to catch a tilted head soaking a parking lot or a zone that quietly stopped firing. Ask how often it happens and whether it is in the base price.

Fix what they find, and tell you

Heads, valves, solenoids, wiring and line breaks are routine. On a commercial contract the real question is what you hear about it. Texas requires a written, sealed record of repair work and materials; some companies add a regular irrigation report.

Change the program with the season

Houston can swing from a week of rain to weeks of heat. A controller still on its July schedule in November is buying water the turf does not need. Smart controllers adjust from weather data; a standard controller relies on someone changing it.

Keep the backflow assembly legal, and protect it from freezes

Systems tied to drinking water need approved backflow protection and tests by a licensed tester, covered below. Houston’s hard freezes can also split an exposed assembly, so agree who protects it when one is forecast.

Which companies do commercial irrigation in Houston?

Each entry below uses only what the company says on its own site. Service areas and service lists change, so confirm both before you invite a bid.

Houston Commercial Landscaping

A commercial grounds company that says it has served Greater Houston since 2006, across Harris, Fort Bend, Montgomery, Brazoria and Galveston counties, for office parks, HOAs, retail, industrial and medical sites. Its site describes smart controller installation, repair and seasonal programming across all major brands, with controller upgrades aimed at local watering restrictions. We did not see an irrigator license number on the pages we read, so ask for it.

Best for: mid-size commercial sites that want grounds, drainage and irrigation from one local contractor.

Lawn Management Company (LMC)

A family-owned Houston commercial landscaper that says it has operated since 1980 and serves more than 1,100 commercial accounts. Its irrigation page is the most detailed in this group: two irrigator license numbers, commercial design and installation, smart controllers fed by on-site weather stations, and a TCEQ backflow tester license with annual backflow inspections and paperwork handled for clients. Drainage and freeze preparation round it out. It lists Houston, Bellaire, Baytown, Cypress, Conroe, Angleton, Wharton, Columbus and Victoria.

Best for: properties that want irrigation, backflow testing and drainage handled by one commercial contractor with its licenses on show.

Monarch Landscape Management

A Houston commercial landscaper that says it has served property managers, facility managers and association boards since 2002, with more than 150 staff. Its irrigation page lists inspections, check-ups and installation, and says its team includes licensed irrigators and backflow testers. Two points stand out for a manager: it inspects the whole system each time and submits a detailed irrigation report, and it repairs anything its own crew breaks without charge. It also recommends smart, weather-based controllers.

Best for: managers who need a written irrigation report they can forward to an owner or board after every inspection.

Southwest Irrigation Systems

An irrigation, drainage and lighting specialist that says it has served greater Houston since 1985, with offices in Rosharon, northwest Houston and Richmond. It publishes both its irrigator license number and a backflow tester number on its homepage, and lists membership in the Houston Gulf Coast Irrigation Association and the Texas Turf Irrigation Association. Most of its site speaks to homeowners, though it says property management companies refer work to it.

Best for: smaller commercial sites or HOAs that want a dedicated irrigation firm separate from their mowing contractor.

U.S. Lawns (Houston North and Houston West)

A national franchise whose two Houston offices say they share one local owner, who also runs a Montgomery County location. Houston North names Spring, Kingwood, Tomball and Humble; Houston West names Sugar Land, Katy, Cypress, Bellaire and West Harris County, and both publish the zip codes they serve. Their irrigation contracts cover maintenance and repairs, new installations, upgrades such as smart controllers, rain sensors and replacement backflow valves, seasonal servicing, and urgent response to burst pipes.

Best for: commercial properties in north and west Houston zip codes that want a local owner backed by a national brand.

Yellowstone Landscape

A national commercial landscaper that says it has served Houston for more than 30 years, with five branches in central, south, southeast, southwest and north Houston. Its irrigation page lists wet checks of every zone, prompt repairs, head and pipe repair, clock maintenance, coverage inspections and regular irrigation reports. Ask the branch for the license number of the irrigator who will be in charge of your site.

Best for: owners and managers with several properties across the metro, or across states, who want one vendor and one reporting format.

Landscapes USA, Houston (the publisher of this page)

A partner-owned commercial and HOA landscape management company with a Houston office on Warwana Road in west Houston. Its Houston irrigation work is repair-led: misaligned or clogged heads, dead zones, stuck valves, damaged wiring, failed solenoids, storm-damaged controllers and backflow preventer problems. Crews walk every zone, finish most repairs on the first visit, say before leaving if a part has to be sourced, and reset the controller for the season. Irrigation monitoring and seasonal scheduling are also part of its Houston grounds contracts. Ask Landscapes USA for its Texas irrigator license number before you sign, the same check this guide recommends for every company on the list. You can read more on its Houston commercial irrigation repair page.

Best for: commercial properties and HOAs that want irrigation checked and repaired by the same team that maintains the grounds.

What does Texas require of an irrigation contractor?

Texas is stricter than most states here, which helps a buyer: the rules tell you exactly what to ask for.

A state irrigator license, held by a named person

Under Chapter 1903 of the Texas Occupations Code, anyone who sells, designs, installs, maintains, repairs or services an irrigation system, consults on one, or connects one to a water supply needs a license from the Texas Commission on Environmental Quality (TCEQ). The detailed rules are in 30 Texas Administrative Code Chapter 344. The company owner need not be licensed, but the business must have a licensed irrigator in charge supervising the work. The exemptions are narrow, such as a homeowner working on their own home. A contracted crew on your property is not exempt.

What must be on their paperwork

• Work vehicles must show the license number as “LI” plus digits, in letters at least two inches high on both sides.
• Advertising, bids, estimates and invoices must carry the irrigator’s name and license number, and the bid paperwork a statement that TCEQ regulates irrigation in Texas.
• Installation contracts must be written, signed by both parties and state the warranty dates.
• Repair work ends with a written, sealed record of work and materials. A new system ends with a walk-through, a signed maintenance checklist with a seasonal watering schedule, and an as-built drawing.

Backflow prevention and testing

A system tied to drinking water must be protected so irrigation water cannot be pulled back into the supply. Where there is a health hazard, the state allows an air gap, a reduced pressure principle assembly, or a vacuum breaker installed under set conditions. Injecting any chemical into the system requires a reduced pressure assembly or air gap. A double check valve is allowed only with no health hazard and where the local authority permits it.

Testing is where commercial sites get caught out. A licensed backflow tester must test each assembly when it is installed, repaired, replaced or relocated, and every year on systems designated as health hazards. When an irrigator puts an assembly into service, results go to the water provider within ten business days. Your provider may require more, so ask your contractor which schedule applies to your meter and who files the report.

What are Houston’s watering rules right now?

No drought stage is in effect, according to the City

Houston Public Works’ current watering restrictions page says the City rescinded Stage One of its Drought Contingency Plan effective May 29, 2024, and it still asks customers to fix leaks and make sure sprinkler heads are not spraying into streets or storm drains. Check that page again before you set a summer schedule, because the stage is declared by the City and can change quickly in a hot, dry spell.

What changes when a stage is declared

The City’s plan has four stages. Stage I is voluntary and asks for two-day-a-week watering with no watering between 8 a.m. and 7 p.m. Stage II is mandatory and limits outdoor watering to the hours between 7 p.m. and 8 a.m. on no more than two days a week, or one day a week if the declaration says so. Under the plan, customers other than single-family homes, which includes commercial properties, water on Tuesdays and Fridays, or Tuesdays only on the one-day schedule. From Stage II, water running off the property onto streets, gutters or neighboring land is unlawful.

Why it matters more on a commercial site

Commercial controllers run at night with nobody watching, so a site can be out of compliance for weeks. Your contract should say who watches for stage changes and reprograms each controller. Also check who supplies your water: many Houston-area properties sit in a municipal utility district or another city with its own drought plan.

What drives the cost of commercial irrigation work?

We do not publish prices here, because irrigation pricing depends on the site in ways a single figure would hide. These are the things that move a bid:

• Zone and controller count. Wet checks are priced on the time it takes to run and walk every zone.
• Age and condition of the system. Old valves, brittle pipe and mixed head brands mean more repairs per visit.
• Inspection frequency. Monthly checks cost more up front and usually less in water and dead turf.
• Whether repairs are included or billed. Some contracts include parts up to a limit; others bill every head.
• Backflow testing and filing. Count the assemblies on site and confirm whether testing is in the contract.
• Controller upgrades. Smart controllers add up-front cost but can pay back through lower water bills.
• Access and timing. After-hours work on retail and medical sites and emergency call-outs cost more.

For the wider picture of how a grounds contract should be structured before you compare anything, see our guide on how to choose a commercial landscaping company in Houston.

What should you ask every irrigation bidder?

1. Whose LI number is on the bid? Look it up on the TCEQ license search.
2. How many inspections a year, and is every zone run each time?
3. What arrives after an inspection: a report, a repair list, or just an invoice?
4. Who tests the backflow assemblies, and who files the results?
5. Who reprograms the controllers when a drought stage is declared?

Frequently asked questions

Does a commercial irrigation contractor in Texas need a license?

Yes. Anyone who designs, installs, maintains or repairs irrigation for others needs a TCEQ license, and a licensed irrigator must supervise the work. Ask for the LI number and look it up.

How often does a backflow preventer need testing in Houston?

At installation, repair, replacement or relocation, and every year on systems designated a health hazard, by a licensed tester. Your water provider can require more.

Which days can commercial properties water in Houston?

Right now the City reports no drought stage in effect. When a stage is declared, the City’s plan puts non-residential customers on Tuesdays and Fridays, or Tuesdays only under the strictest watering schedule, between 7 p.m. and 8 a.m.

Is a smart irrigation controller worth it on a commercial site?

Often, on sites with many zones and nobody checking the schedule. It skips watering after rain and adjusts to the weather, but someone still has to set it up and check it.

Should my landscaper also handle irrigation?

One contractor means one call when a bed dies, and no argument over whose fault it was. A specialist can bring deeper expertise. Either works if the contract says who checks, repairs and reports.

What should I get in writing after an irrigation repair?

A written, sealed record of the work and materials, which Texas rules require. A good contractor also lists other faults it found, so you can approve them early.
