If you’re a homeowner here in Maryland, you already know our weather keeps you on your toes. One week we’re mowing the lawn in 78° sun, and the next we’re pulling out winter coats because the nights dipped below freezing without warning.
Those temperature swings can be brutal on a sprinkler system.
That’s why one of the most common questions I get—every single year—is:
“Bob, what does it really cost to have TLC handle both my spring sprinkler startup and my fall winterization?”
In this article, I’m going to walk you through:
- What a startup includes
- What winterization includes
- What a full-service, year-round package costs
- What affects the price
- How Maryland weather impacts your sprinkler investment
- Why skipping these services can cost you far more later
- When membership makes more sense than à-la-carte service
- Real examples from right here in our TLC service area
Why Sprinkler Startup and Winterization Matter More in Maryland Than Most Places
Here in the Mid-Atlantic, we get:
- Freeze-thaw cycles
- Sudden temperature drops
- High humidity
- Uneven rainfall
- Long, dry summers
All those conditions mean a sprinkler system takes a beating, even when it’s not turned on.
Your system contains:
- Backflow preventer
- Valves
- Zones
- Pipes
- Spray heads
- Rotor heads
- Drip lines
- Wiring
- Timers
- Pressure regulators
- Manifolds
Each can freeze, crack, clog, or malfunction without proper seasonal prep.
