What typically needs to be done
- The perimeter inspection looks for soil sloping toward the house, ponding, erosion, downspout problems, new gaps along the foundation and changes in visible cracking.
- Drainage components such as gutters, downspouts, extensions, window wells and sump discharge are considered together because they all influence where water goes.
- Changes are documented over time so a new condition can be distinguished from an old stable one.
What you can check or prepare yourself
- Walk the home after a rain or snowmelt and note where water actually collects.
- Photograph cracks with a ruler or other scale and date the photo rather than relying on memory.
- Keep downspout outlets and surface drainage paths clear and direct water away according to the property grading/design.
- Escalate rapidly changing cracks, doors/windows suddenly binding, wall movement or active water entry to an appropriate professional.
Step-by-step reminder
- Walk the perimeter and look for negative grading, ponding, erosion or new gaps at soil/foundation edges.
- Confirm downspouts discharge away from the foundation.
- If the home has a sump pump, test its float switch and discharge path.
- Document new cracks or movement so changes can be compared over time.
Structural movement, rapidly changing cracks or water intrusion deserve evaluation by an appropriate qualified professional.
Before you start
Review the manual for the exact appliance, system or material in your home before opening panels, disconnecting utilities, changing settings or using chemicals. Model-specific procedures and local installation details can differ from a general guide. Shut off power, water or fuel only when the manufacturer procedure calls for it and you are comfortable identifying the correct control. Stop if the condition you find is different from what is described here.
When to bring in a professional
The homeowner checks above can help you understand the condition of the system and prepare for service, but the higher-risk portion may require specialized tools, safe access, combustion/electrical knowledge, refrigerant work, pressure equipment or a qualified inspection. Use the typical-work list to understand what a proper service visit should cover, and hire the appropriate professional for work outside normal homeowner access.
This guide is general information, not a home inspection or a guarantee that a procedure is suitable for your specific equipment or conditions. Follow manufacturer instructions and applicable codes, stop if anything appears unsafe or different from the guide, and use a qualified professional when appropriate.
