Common Causes of Home Water Intrusion (and How to Prevent Them)
Home Water Intrusion – Most Common Causes
1. Roof Leaks
Damaged or missing shingles, clogged gutters, and poor flashing can all allow water to seep in through the roof—especially during storms.
Prevention Tip:
Inspect your roof regularly, clean gutters seasonally, and repair any signs of wear promptly.
2. Poor Grading and Drainage
If your yard slopes toward your home, water can pool near the foundation and seep inside through cracks or gaps.
Prevention Tip:
Regrade landscaping to direct water away from your home and install a French drain or sump pump if necessary.
3. Faulty or Aging Plumbing
Old or corroded pipes, loose fittings, or worn-out appliances like washing machines or water heaters can leak unexpectedly.
Prevention Tip:
Inspect exposed pipes and hoses for damage and schedule annual plumbing checkups. Replace rubber hoses with braided steel ones.
4. Cracked Foundations or Basement Walls
Small foundation cracks can allow groundwater or rainwater to seep in over time, especially in older homes or those without waterproofing.
Prevention Tip:
Seal cracks as they appear and consider applying a waterproof membrane to basement walls if water intrusion is ongoing.
5. Window and Door Leaks
Improperly sealed or aging window and door frames can let water in during heavy rain or if landscaping directs water too close.
Prevention Tip:
Check caulking and weather stripping regularly and reseal when worn or cracked.
Keep An Eye Out for Home Water Intrusion
By understanding the most common sources of home water intrusion, you can catch small issues before they become major repairs. A little maintenance goes a long way—but when damage does occur, calling in a professional restoration team ensures the job gets done right, from cleanup to structural drying.
