Common Causes of Water Damage in Pasadena Homes

Water Restoration

Water damage can be a homeowner’s worst nightmare—costly, messy, and often unexpected. Whether it’s a slow leak or a sudden flood, knowing the common causes of water damage can help you prevent disaster before it strikes. In Pasadena, where a mix of historic homes and seasonal weather presents unique challenges, being prepared is half the battle.

At PuroClean of Pasadena, we’ve helped countless families recover from water-related issues. Based on our experience in the community, here are the top culprits behind water damage—and what you can do about them.


1. Leaky or Burst Pipes

One of the most common causes of water damage is leaky or burst pipes. In Pasadena, older plumbing systems in historic homes are especially vulnerable. Corroded pipes or worn-out joints can eventually give way, releasing water behind walls or under floors.

Tip: Have your plumbing inspected regularly and consider upgrading old piping to prevent costly emergencies.


2. Roof Leaks

A damaged or aging roof can allow water to seep into your attic or walls, especially during Pasadena’s winter rains. Missing shingles, cracked flashing, or clogged gutters often lead to roof leaks.

Tip: Get your roof inspected yearly and clean out your gutters before the rainy season to reduce the risk.


3. Faulty Appliances

Washing machines, dishwashers, water heaters, and refrigerators can all malfunction and leak water. A worn hose or broken valve is all it takes to flood part of your home.

Tip: Replace appliance hoses every 5–7 years and check for signs of wear, especially if your appliances are older.


4. Blocked Drains

Clogged sinks, tubs, and toilets can overflow and cause water to back up into your home. In some Pasadena neighborhoods, tree roots can even clog sewer lines, causing major issues.

Tip: Avoid flushing anything other than toilet paper and hire a plumber to snake your drains regularly.


5. HVAC Issues

Your air conditioning system produces condensation, which should drain properly. But if the drain line is blocked or the unit malfunctions, it can leak into your walls or ceilings.

Tip: Schedule annual maintenance for your HVAC system to ensure all components are functioning properly.


6. Weather and Storms

While Pasadena isn’t known for extreme weather, heavy rains and occasional flash flooding do occur—especially in areas near the Arroyo Seco or San Rafael Hills. Poor drainage around your home can lead to basement or foundation leaks.

Tip: Make sure your yard is graded away from your home and install proper drainage systems if needed.
