Brown Spots in Your Lawn

If patches of your lawn are turning brown while neighboring areas stay green, your sprinkler system isn't delivering water evenly. The fix is usually quick — once you know which head is the problem.

Likely causes

What's usually causing this

01

Broken or cracked sprinkler head

A head that's been hit by a mower, edger, or vehicle splits along the riser. Water pools at the base instead of spraying. The brown patch sits directly downstream of where coverage should be.

02

Clogged nozzle from sediment

Texas water carries sediment, especially after main breaks. A partially clogged nozzle still pops up but sprays a weak, uneven pattern — leaving the far edge of its zone dry.

03

Sunken or tilted head

Heads can sink as soil compacts over years. A tilted head sprays at the wrong angle, missing the area it was installed to cover. Brown spots in a consistent pattern across the lawn often point to multiple settled heads.

04

Zone pressure problem

If multiple heads on one zone are weak, the issue may be upstream — a partially closed valve, a kinked line, or a pressure regulator that's failing. The whole zone underperforms even though no single head looks broken.

How we fix it

Our repair approach

We diagnose by running each zone manually and watching the heads. Most brown-spot calls are resolved in under an hour: pop the suspect head, inspect it, replace or clean the nozzle, and re-test the pattern. If the issue is upstream pressure, we trace the zone back to the valve and pressure regulator before quoting any larger work.
