How to pick a irrigation & drainage pro in McHenry County, IL
- Required by Illinois law: the contractor must call JULIE / 811 at least 48 hours before any digging. If they say 'we don't bother,' walk away — they're a liability.
- Ask for BAT (Backflow Assembly Tester) certification for sprinkler installs. Crystal Lake requires backflow prevention on irrigation tied to municipal water.
- For drainage work, get a written grading plan. 'We'll just dig it out' is how flooded basements get worse.
- Verify the warranty on the system AND the workmanship. 5-year on parts, 1-year on labor is industry standard.
Frequently asked questions
Why is my backyard always wet after it rains?
Three usual causes: (1) negative grade slope toward the house, (2) compacted clay subsoil, (3) downspouts dumping at the foundation. A drainage contractor should diagnose with a level and dye-test before quoting any work.
How much does a sprinkler system cost?
$2,500-5,000 for a quarter-acre. The big variables are number of zones (more zones = more pipe + valves) and water source (tying into city main = cheaper than a well booster pump).
Do I need a permit for irrigation work in Crystal Lake?
Yes for any work that ties into the city water main — backflow preventer is mandatory and inspected. Standalone systems on a well typically don't need a permit.
What's a French drain and when do I need one?
A perforated pipe in a gravel-filled trench that collects groundwater and redirects it. Use it when you have chronic wet spots, water seeping into a basement, or boggy lawn areas. NOT a fix for downspout overflow — that's surface drainage.
