Pasadena is famous for its charming historic homes, from Craftsman bungalows to Spanish Revival estates. These beautiful properties add unique character to our neighborhoods, but they also come with a unique set of challenges—especially when it comes to plumbing leaks and slab damage.
If you live in an older Pasadena home, it’s important to understand the risks and warning signs so you can take action before a small issue turns into a costly repair.
Why Plumbing Leaks Are Common in Older Homes
Many of Pasadena’s historic homes were built before 1950—long before modern plumbing standards. Older homes often have galvanized steel or clay pipes, which are prone to corrosion, cracking, or root intrusion over time. These aging systems are ticking time bombs for plumbing leaks.
Even minor leaks under the floors or behind walls can go unnoticed for months, quietly damaging your home’s foundation or encouraging mold growth.
Slab Damage: The Hidden Risk Beneath Your Feet
A slab leak occurs when a pipe under your concrete foundation starts to leak. These types of leaks are especially dangerous because they’re hidden from view. In historic homes with original plumbing, the risk of slab leaks increases significantly due to pipe deterioration.
Over time, slab leaks can cause:
- Cracks in your foundation or floors
- High water bills
- Warm spots on the floor
- Mold or mildew from excess moisture
- Shifting floors or buckling wood
Signs You Might Have a Plumbing Leak
Not sure if your older home has a plumbing issue? Here are common red flags:
- Sudden spike in your water bill
- Low water pressure
- Hearing water running when taps are off
- Unexplained moisture or water stains on walls or floors
- Moldy or musty smells
- Cracks forming in your slab or tile flooring
If you notice any of these signs, don’t wait—contact PuroClean of Pasadena to assess the damage and recommend a remediation plan. Quick action can save you thousands in long-term repairs.
What You Can Do to Prevent Damage
Pasadena homeowners can take proactive steps to prevent plumbing leaks and slab issues:
- Have your plumbing inspected every few years, especially if your home is 50+ years old.
- Install a leak detection system that monitors water flow and alerts you to potential issues.
- Keep trees and large shrubs away from water lines to prevent root intrusion.
- Replace outdated pipes with PEX or copper as part of a remodel or maintenance plan.
- Don’t ignore small signs—early leaks are easier and cheaper to fix.
