The short answer
What Causes a Soggy Yard
A soggy yard often results from overwatering, poor drainage, or a recent rainstorm. In a climate with wet winters and dry summers, the ground can stay damp for days after rain. But if a patch stays wet while the rest dries, that is a clue something else is happening.
A leak in the main water line that runs from the street to your house can push water upward through the soil. The leak may be small at first, so the soggy area grows slowly. Other causes include a broken sprinkler head, a cracked irrigation pipe, or a high water table that keeps the ground saturated.
- A wet patch that never dries out
- A sudden increase in your water bill
- Puddles forming after no rain
- Unusually lush or green grass in one area
- A hissing sound near the ground
- Cracks in the soil or sinking spots
How to Check for a Main Line Leak
Start by looking for other signs, like a wet spot near the water meter or along the path of the pipe. Turn off all water inside your home and check the meter. If the meter still moves, water is escaping somewhere, and a main line leak is likely.
You can also listen for the sound of running water near the suspected area, especially on a quiet day. Dig carefully if you want to inspect, but avoid hitting any buried cables or pipes. If you are unsure, a leak detection service can pinpoint the issue without digging up your whole yard.
When to Call the Pros
If you confirm or strongly suspect a main line leak, call local water damage pros. They have specialized equipment to find the exact location of the leak, such as acoustic listening devices and moisture meters. This saves time and avoids unnecessary digging.
The pros can also handle the cleanup if water has reached your foundation or crawl space. They will assess the extent of the damage and start the drying process. Acting quickly helps minimize structural issues and mold growth, so do not wait to make the call.
What the Repair Involves
Repairing a main line leak usually requires digging down to the pipe, cutting out the damaged section, and replacing it. The pros will use a pipe wrench and other tools to make the repair. They may also recommend a pressure test to check that the pipe is sound.
After the repair, the pros will backfill the trench and compact the soil. You may need to reseed or resod the grass. The cost depends on the depth of the pipe, the length of the damaged section, and how accessible the area is. A typical repair often ranges from a few hundred to a couple thousand dollars, but the final price depends on your specific situation.
- Turn off the water supply before any work
- Mark the leak location for the pros
- Keep the area clear of furniture and debris
- Plan for some yard disturbance during the repair
Preventing Future Leaks
Main line leaks often happen due to age, ground movement, or freezing. While you cannot always prevent them, you can reduce the risk. Know where your main shutoff valve is located and write it down. If you live in Redmond, keep that information handy for emergencies.
Consider having a plumber inspect your main line if your home is older. They can check for corrosion or weak spots. Also, avoid planting trees or shrubs with aggressive roots near the pipe, as roots can invade and crack the line over time.

How can I tell if it is a main line leak or just rain?
A main line leak usually creates a concentrated wet spot that persists even in dry weather. Rain affects the whole yard evenly. Check the water meter with all water off; if it moves, you have a leak. Also, look for unusually green grass or puddles that do not dry.
What should I do if I suspect a main line leak?
Turn off your main water valve to stop the flow and prevent further damage. Then call a plumber or water damage pro to confirm the leak and locate it. Do not delay, as a small leak can quickly erode soil and undermine your foundation.
Will my insurance cover the repair?
Policies vary, and your insurer decides what is covered. Some policies cover water damage from a sudden leak, but not gradual wear. Check your policy documents or talk to your insurance company. They may require proof of the leak and the repair cost.
