Casas Irrigation provides sprinkler repair, smart controller installation, French drain construction, and landscape lighting services to Allen, TX homeowners across ZIP codes 75002 and 75013. Our crews operate to the standards required by Allen Public Works and the North Texas Municipal Water District (NTMWD), which mandates a year-round 2-day-per-week outdoor watering schedule across all member cities including Allen. Whether you need a same-day sprinkler head repair in Twin Creeks, a Rachio or Hunter Hydrawise controller programmed for NTMWD compliance in Watters Crossing, or a French drain installed to handle the Houston Black clay drainage challenges in Star Creek, our licensed technicians dispatch from our Frisco service center to Allen addresses within 24 hours of your call.
Why Allen Lawn Irrigation Requires Local Expertise
Three local realities shape how every Casas Irrigation crew approaches an Allen property. Understanding them is the difference between an irrigation system that works for a year and one that works for a decade.
1. NTMWD’s Mandatory 2-Day Watering Schedule (Year-Round)
Allen is a member city of the North Texas Municipal Water District. NTMWD sources treated surface water from Lake Lavon, Lake Texoma, Jim Chapman Lake, and Lake Tawakoni — and enforces year-round Stage 2 mandatory restrictions across all member cities. From April 1 through October 31, no outdoor watering is permitted between 10:00 AM and 6:00 PM. Even-numbered addresses water Mondays and Thursdays; odd-numbered addresses water Tuesdays and Fridays. Violations are tracked through Allen Public Works and assessed via the water bill.
What this means for your system: a standard mechanical controller can no longer be programmed to honor these rules reliably. Every smart controller we install in Allen (Rachio, Hunter Hydrawise, Rain Bird LNK) includes NTMWD-compliant scheduling that pauses during the 10 AM–6 PM blackout and rotates correctly between the assigned even/odd days.
2. Houston Black Clay Soil + Rowlett Creek Drainage Patterns
Most of Allen sits on Houston Black clay – the same expansive, dense soil that runs through Collin County. This soil resists irrigation absorption AND resists storm runoff. The Rowlett Creek watershed runs through Allen, and lots near the creek corridor (much of Twin Creeks) often experience persistent low-spot pooling after spring storms. Two practical consequences:
- Surface runoff happens fast during normal irrigation. Long single-cycle watering wastes water and triggers NTMWD violation flags. Every Allen controller we install is programmed for cycle-and-soak (multiple short cycles with rest periods).
- Drainage projects in Allen – particularly French drains – represent a higher share of total project volume than in sandier suburbs. Star Creek and east-side lots near the floodplain see the most demand.
3. Foundation Watering Is Allowed Any Time (And You Need It)
Allen’s NTMWD watering rules do not apply to foundation watering with a soaker hose, up to 2 hours per session. On expansive Houston Black clay, foundation soaker hoses are not optional — they prevent the slab heave that costs Collin County homeowners thousands in foundation repair every summer. We install dedicated foundation-watering zones on every new system and retrofit existing systems on request.
Irrigation, Drainage & Lighting Services in Allen, TX
Sprinkler Repair (Same-Day Available)
Broken sprinkler heads, leaking valves, electrical solenoid failures, low-pressure zones, and timer/controller faults. We carry common Rain Bird, Hunter, Toro, and Irritrol parts on every truck — most Allen sprinkler repair calls are resolved in a single visit. Typical residential sprinkler repair in Allen runs per call depending on parts.
Smart Controller Installation
Rachio 3 and 3e, Hunter Hydrawise, Rain Bird LNK Wi-Fi modules. Every install includes NTMWD’s even/odd schedule, the 10 AM–6 PM blackout window, and zone-specific cycle-and-soak intervals tuned for Houston Black clay. EPA WaterSense-labeled controllers may qualify for utility rebates.
French Drain & Drainage Installation
French drains, channel drains, downspout extensions, dry creek beds, sump pumps, and yard grading. Most residential French drain projects in Allen run depending on linear footage and depth. Allen does not require a permit for residential French drains on your own property, but utility crossings require an 811 locate call — we handle that for you.
Landscape Lighting Design & Installation
Low-voltage LED path, accent, and architectural lighting. Watters Crossing and the streets surrounding Watters Creek at Montgomery Farm see particularly strong demand for accent lighting that complements the upscale streetscape. Engineered for North Texas freeze-thaw cycles that fail cheap big-box lighting kits within two summers.
Sprinkler Winterization & Blowout
North Texas freezes are short but severe. We use compressed air to clear lines, drain backflow assemblies, and protect controllers before the first hard freeze. Standard winterization service for an Allen residential system.
Backflow Testing & RPZ Certification
Texas state law requires annual backflow assembly testing on residential and commercial systems with RPZ devices. We are TCEQ-licensed to perform certified tests and file the report directly with Allen Public Works on your behalf.
Where in Allen We Work
We dispatch to every Allen ZIP code (75002 and 75013). The three communities below represent our highest project volume in Allen over the last 24 months.
Twin Creeks (75013)
Allen’s master-planned community centered on the Arnold Palmer-designed 18-hole golf course. Mature, irrigation-dependent landscaping with 15- to 20-year-old systems entering retrofit territory. Homes near the Arnold Palmer course rely on irrigation precision — overspray onto fairways or cart paths is a common HOA complaint, and we routinely retrofit perimeter zones with MP Rotators or pressure-regulated heads to fix it. Twin Creeks Community Association requires specific landscape standards, and our crews work within those guidelines.
Watters Crossing (75013)
Adjacent to the Watters Creek at Montgomery Farm shopping district. Newer construction with high concentration of smart controller installations and landscape lighting projects. Proximity to Watters Creek at Montgomery Farm and the surrounding boulevard landscape sets the bar high for residential systems. Most Watters Crossing service calls are smart controller upgrades, drip-irrigation conversion of planting beds, and landscape lighting expansion.
Star Creek (75002)
East-side master-planned community on Houston Black clay-heavy lots. Higher project volume for drainage solutions and French drain installations following spring storms. The clay-heavy lots and proximity to natural drainage corridors make French drain installations particularly common here. We have completed projects throughout Star Creek to redirect downspout runoff, install side-yard channel drains, and grade backyards away from foundations.
We also serve: Ridgeview, Suncreek, Custer Hill, Bethany Lakes, Cottonwood Bend, North Allen, Central Allen, and every other Allen neighborhood. If you’re inside the Allen city limits in 75002 or 75013, we dispatch.
What North Texas Homeowners Say About Our Work
⭐⭐⭐⭐⭐
“I’m so glad I got a second opinion with Luis at Casas Irrigation. Our first initial appointment with another company, we were quoted almost 3k that’s when I thought that a small leak with our irrigation would not cost so much. I reached out to Luis right away and he was able to schedule me a few days out. Jorge and another gentleman showed up and was able to fix our issue within a few hours. He also cleaned up the area as if nothing happened. The other company created such a mess when they came and was so unhappy about that. Thank you Luis, Jorge and team for doing a great job and for saving me thousands of dollars. You have gained a loyal customer and I’m definitely recommending your team to others! I’ll be reaching out again to do our external lighting!”

“My wife and I are building a new home, and we were thinking the property needed some drainage work as it tends to flood in one area. We contacted Casas Irrigation and Luis was able to meet me at the property within a few days to scope things out. Luis walked the property with me and informed me we won’t need anything for drainage as the grading contractors did a great job. He suggested we just have the graders add some more dirt to the one area that tends to flood and have it slope out towards the ditch. He did all this on his own time and didn’t charge us anything. We greatly appreciate Luis’ honesty as so many contractors in the same situation would have taken advantage of us. It is so hard to find contractors these days who demonstrate integrity and desire to truly do what’s best for the customer — not their own wallet. We will definitely reach out to Casas if we ever need anything in the future.”

Frequently Asked Questions (FAQs)
What are the current outdoor watering rules in Allen, TX?
Allen follows the North Texas Municipal Water District Stage 2 mandatory rules year-round. Outdoor irrigation is limited to 2 days per week. From April 1 through October 31, no watering is permitted between 10:00 AM and 6:00 PM. Even-numbered street addresses water on Mondays and Thursdays; odd-numbered addresses water on Tuesdays and Fridays. Hand watering with a shut-off nozzle and foundation watering with a soaker hose (up to 2 hours per session) are permitted any time. Allen Public Works tracks violations and assesses penalties through the regular water bill.
How much does sprinkler repair cost in Allen?
Most residential sprinkler repair service calls in Allen run $85 to $250, including the diagnostic, common replacement parts (heads, nozzles, solenoids, wire repairs), and labor. Major repairs like full valve replacement or controller swaps typically fall between $250 and $650. We carry standard Rain Bird, Hunter, Toro, and Irritrol parts on every truck, which means about 9 out of 10 Allen repair calls are completed in a single visit.
Do I need a permit to install a French drain in Allen, TX?
Allen does not require a permit for residential French drain installations on your own property. Any excavation crossing utility lines requires an 811 locate call before digging — this is Texas state law. If the French drain ties into the public storm sewer or crosses into the City right-of-way, Allen Public Works will require a permit. We handle the 811 call and any required permitting on every project.
Why is my sprinkler system using so much water in Allen?
The three most common causes in Allen are: (1) Houston Black clay soil causing surface runoff during long single-cycle watering — the fix is cycle-and-soak programming; (2) hidden underground leaks at valves or pipe joints, which can waste 50+ gallons per zone per cycle without showing on the surface; and (3) an older mechanical controller that cannot honor the NTMWD 10 AM–6 PM blackout, leading to overwatering during peak evaporation hours. A smart controller upgrade and a 30-minute system audit will identify which of the three applies.
Can I get a watering exemption in Allen for new sod?
Yes. Allen Public Works offers a new landscape establishment exemption that allows daily watering for up to 30 days following sod or hydromulch installation. The exemption must be requested through Allen Public Works before the installation begins. Overseeding does not qualify. All water used during the exemption period is the responsibility of the account holder. We can schedule your sprinkler installation to coincide with the exemption window.
What smart sprinkler controllers work best for Allen’s watering schedule?
The three controllers we install most often in Allen are the Rachio 3 (or 3e), Hunter Hydrawise, and Rain Bird LNK Wi-Fi modules. All three support the even/odd schedule, the 10 AM–6 PM blackout window, weather-based skipping, and cycle-and-soak programming required for Houston Black clay. The Rachio 3 has the cleanest mobile interface; Hunter Hydrawise offers the strongest professional-monitoring features; Rain Bird LNK works best as a retrofit on existing Rain Bird systems. EPA WaterSense-labeled models may qualify for utility rebates.
Is Casas Irrigation licensed to do backflow testing in Allen?
Yes. We are licensed by the Texas Commission on Environmental Quality (TCEQ) to perform backflow assembly testing and certified RPZ device testing. Texas state law requires annual backflow testing on all residential and commercial irrigation systems with RPZ devices, and the test report must be filed with the local water utility. We perform the test, complete the TCEQ-required documentation, and submit the report to Allen Public Works on your behalf.
When should I winterize my sprinkler system in Allen?
Winterize before the first sustained freeze, which historically arrives in Allen between mid-November and mid-December. A proper sprinkler winterization uses compressed air to blow water out of the supply lines, drains the backflow assembly, and shuts down the controller. Skipping winterization on a North Texas system causes more spring repair calls than any other single issue — frozen water expanding inside a backflow assembly will crack the brass body, a $400+ replacement that a $130 winterization would have prevented.
