Protect Your Lawn Sprinkler System Before the First Freeze
Most Maryland homeowners pay between $3,850 and $35,000 for a fully installed and warrantied underground sprinkler system. Your exact price is driven by three things: lawn size, number of zones, and what's in the way.
The total price of your sprinkler systems depends on the number of zones, plumbing tie-in, submeter options (if allowed in your county/jurisdiction), and directional boring requirements.
Typical smaller residential property or front-yard application.
$3,850-$5,000
Covers roughly 5,000 to 10,000 square feet, the size of around 1 to 2 basketball courts.
$5,500-$9,000
Covers 10,000 square feet up to a full acre or more, so anything more than the size of a couple of tennis courts.

A new sprinkler system can be a significant upfront investment, so TLC offers flexible financing through Slice® by FNBO to help you spread the cost over time. Financing is available for qualifying projects with fixed-interest loans up to $150,000, a simple digital application, and no hidden fees or prepayment penalties. You can explore your options and get pre-approved before moving forward with your project.
Zone count, total coverage area, how many hardscapes (driveways, patios, walkways) need to be crossed, slope and soil conditions, and whether directional boring is required all affect the number. Open, level lawns with fewer zones cost less; larger or more complex properties cost more.
Cheaper quotes are often cheaper for a reason — inferior pipe and fittings, wider head spacing than the yard needs, no smart controller or rain sensor, and no real written warranty. More expensive quotes are sometimes padded by large franchise overhead or extras you don't actually need. TLC prices every system based on your exact yard, with pro-grade parts and a 7-year warranty included.
Most systems need an annual winterization and spring start-up. Ask your estimator for current maintenance plan pricing — it's modest compared to repair costs from skipping it.
A properly installed, pro-grade system typically lasts 15–25 years. Systems built with lower-grade parts to hit a cheaper price often need $3,000–$5,000+ in repairs well before then.
The things that most often surprise homeowners with other companies — directional boring, lawn restoration after trenching, rain sensor setup, smart controller sync, and final coverage testing — are built into TLC's quoted price up front, not added afterward.
Pipe, fittings, and valves have increased 20–30% since 2020.
For most homeowners, yes. It protects the investment you've already made in your lawn and landscaping, saves the time of manual watering, and a weather-based smart controller means you're never paying to water a lawn that's already getting rain.
