If you’ve ever hired a contractor—sprinkler or otherwise—you know how stressful it can be. You’re trusting someone with your home, your lawn, and your hard-earned money. And in today’s world, with AI-generated ads and flashy websites, it can be even harder to figure out who actually knows what they’re doing.
At TLC Incorporated, we’ve spent 42 years serving Maryland, Northern Virginia, and Washington, D.C. We’ve seen good work, bad work, and everything in between. So if you’re a homeowner wondering how to spot a quality sprinkler contractor, here’s what you should be looking for.
1. They Ask the Right Questions First
Any contractor who shows up and says, “We can do that!” before asking about your yard’s layout, water pressure, or zone needs is skipping the most important step: understanding your lawn. Good contractors listen before they talk.
Real-World Example: We met a homeowner in Laurel who had hired someone else for a backyard system. The contractor didn’t ask a single question about sun exposure or slope—and as you might guess, one zone was completely under-watered. We re-evaluated the design and corrected the flow. The homeowner told us, “You asked more questions in five minutes than they did in the whole job.”
2. They Explain Things Clearly (Without Jargon)
If you don’t know the difference between a valve and a head, that’s okay—you shouldn’t have to. A real pro knows how to explain what you need in plain English. If they talk over your head or dodge basic questions, it’s a red flag.
We believe in showing, not just telling. That’s why we include walk-throughs at every installation and hand you a quick-start guide customized for your system.
3. They Offer Options—Not Just One Package
A quality contractor gives you choices. That might mean recommending a smart controller but explaining what the traditional alternative looks like, too. There’s no “one-size-fits-all,” and a good contractor helps you decide what’s best for your yard and your budget.
Bob’s Tip: If you feel pressured into one package or rushed into signing, that’s your cue to pause. Good contractors build systems around you, not around their sales goals.
4. They Can Show You Real Work They’ve Done
If a contractor can’t name three local jobs they’ve done in places like Bowie, Silver Spring, or Fairfax—be cautious. Ask to see photos, reviews, or talk to a recent customer. Experience shows in results.
Homeowner Story: A homeowner in Bethesda told us she chose TLC because we offered to connect her with two past clients in her area. That conversation gave her confidence before she ever signed the contract.
5. They Educate You (Before and After the Work)
A knowledgeable sprinkler contractor is also a teacher. They’ll show you how your system works, how to run the controller, and what to look for each season. At askbobcarr.com, we publish guides, videos, and FAQs to help homeowners feel confident and informed.
We don’t just set timers—we show you how to adjust them, explain the role of seasonal adjustments, and make sure you know what to do before the first frost.
6. They Stand Behind Their Work
Ask about warranties, seasonal checkups, and service calls. A good contractor is there for you after the install—not just when the invoice is due. That’s why we’ve been called back to homes in Bethesda, Glen Burnie, and D.C. year after year.
Bob’s Note: We’ve had customers from 20 years ago call back for an upgrade—and they still have our number on the sticker inside the controller box. That’s what it means to stand behind your work.
FAQs: Smart Questions to Ask Before You Hire
Q: How many systems like mine have you installed?
A: You want to hear specific examples—bonus points if they name jobs in your zip code.
Q: What brands do you use—and why?
A: A pro should be able to tell you why they use Hunter, Rain Bird, or another brand—not just “whatever’s cheapest.”
Q: What happens if something breaks?
A: Look for clear answers about service calls, turnaround times, and who you’ll speak to.
Q: Will I be able to operate the system myself?
A: If the contractor won’t walk you through the controller or provide a guide, keep looking.
Final Thoughts from Bob
Contractors aren’t all created equal. But the good ones are out there—and they’re usually the ones who take the time to educate you, listen to you, and back up their work long after the truck pulls away.
