From the Desk of Bob Carr:
Every fall, I get the same question from homeowners across Maryland and the surrounding counties: “Bob, how much does it cost to winterize my underground lawn sprinkler system, and why does it matter?”
Let me shoot straight with you. Winterization isn’t an upsell or an optional add-on. It’s the single most important step you can take to protect your sprinkler system before the freezing weather arrives. Skip it, and you’re gambling with cracked lines, busted sprinkler heads, and a backflow device that could cost you hundreds—or even thousands—to repair come spring.
At TLC, we’ve been servicing sprinkler systems for decades, and I want you to have a clear picture of both the process and the pricing.
Why Winterization Matters
When water freezes, it expands. If there’s any water left in your pipes or heads, that expansion creates pressure strong enough to break fittings, split pipes, and ruin valves. By spring, instead of turning on your system and enjoying a green lawn, you could be facing a costly mess underground.
Winterization is simply insurance that your investment will still be in good shape when it’s time to turn the system back on.
What TLC’s Winterization Service Includes
We don’t cut corners. Our team follows a proven process every single time:
– Shutoff: We locate and close your sprinkler system’s main water supply.
– Blowout: Using professional-grade compressors, we safely push every last drop of water out of your system.
– Backflow Protection: We drain and safeguard the backflow preventer so it won’t crack in freezing temperatures.
– Quick System Check: We make note of any broken heads, leaks, or adjustments you may want to address in the spring.
This is not a “DIY with a little pancake compressor” type of job. It takes the right tools and the right know-how.
Let’s Talk Pricing
Every system is different, but here’s what you can expect:
- Smaller Residential Systems (up to 6 zones): $95 – $125
- Medium Systems (7–12 zones): $125 – $175
- Larger Properties (13+ zones): $175 and up
What drives the price up? More zones, larger yards, tricky backflow setups, or hard-to-reach shutoffs. What keeps the price down? Simple layouts, easy access, and fewer zones.
The bottom line: our pricing is straightforward, competitive, and—most importantly—backed by TLC’s guarantee.
Final Word From My Desk
If you take nothing else from this note, remember this: winterization costs a fraction of what spring repairs will cost if your system freezes. My advice? Protect your investment, let us do it right, and head into winter with peace of mind.
