Older homes across Dekalb, especially those built before the 1960s, often have galvanized steel pipes hiding behind the walls and under the floors. While these pipes were popular for decades, plumbers know they corrode from the inside over time. That can mean water pressure drops, rusty discoloration, or leaks that damage drywall and floors. With our region's long winters and frequent freeze-thaw cycles, it's not unusual for these aging pipes to give out when you least expect it.
Why Galvanized Pipes Are a Problem in Dekalb
Galvanized pipes were common in mid-century homes thanks to their durability, but decades of mineral buildup and rust catch up to them. Dekalb's municipal water can vary in hardness, which speeds up scale and corrosion inside old supply lines. On top of that, cold and snowy winters stress pipes further, especially in unheated basements or crawl spaces. Corroded galvanized pipes restrict water flow, often leading to low pressure at sinks and showers. Over time, leaks can form at joints or along weakened areas, which may go unnoticed behind walls for years.
Typical Signs You Still Have Galvanized Piping
Many homeowners don't realize their plumbing is galvanized until problems start to show. Here are some warning flags we look for during inspections:
- Discolored or rusty-looking water from faucets, especially in the morning or after the water has been off for hours.
- Low water pressure, often most noticeable at the shower or when running multiple fixtures.
- Frequent leaks or water stains along ceilings, walls, or under sinks. These often come from pinhole leaks in old pipes.
- Visible pipes with a dull gray color in the basement, utility room, or near the water meter. Copper and PEX are easily distinguished from the heavy, threaded steel of galvanized lines.
- Old pipe connections with threaded fittings rather than the soldered joints used in copper plumbing.
If you spot any of these issues, it's time to think about an upgrade. Galvanized lines often run throughout the entire system, so partial repairs usually don't solve the underlying risk of future leaks.
What Repiping Entails for Dekalb Homes
Full repiping replaces all the old steel supply lines with modern materials such as copper or PEX. In homes 50-70 years old, we commonly see not just the main runs but also the short branch lines to sinks, tubs, and washing machines needing replacement. During a repipe, our team maps out your home's system, shuts off the main water supply, and removes both accessible and hard-to-reach galvanized sections.
Repiping may involve temporary removal of a few sections of drywall or tile, but careful planning keeps disruption minimal. Modern PEX is flexible and allows us to reroute pipes around obstacles with fewer joints. We also inspect isolation valves, hose bibs, and any pressure reducing valves (PRVs) while we're there, as these should match the new system's pressure and flow requirements. If you've had prior basement seepage from Dekalb's clay soil and high water table, now is a good time to evaluate plumbing for sump pump upgrades. You can learn more about these options on our sump pump services page.
Typical Repiping Costs and What Affects Price
No two homes are the same, so repiping costs vary. Factors that have the biggest impact:
- Size of the home and number of bathrooms or fixtures
- Accessibility of old pipes, finished basements vs. open joists can affect labor
- Choice of material, copper costs more than PEX, but both last for decades
- Extent of drywall or tile repairs needed after the job
Our crew follows best practices for code compliance and can walk you through options that balance cost and long-term performance. We recommend replacing all accessible galvanized lines rather than patching one section at a time. Routine leaks or chronic low pressure often signal that the whole system is ready for an upgrade. You can see details on our process at our pipe repair & repiping page.
Other Plumbing Problems Linked to Old Pipes
Galvanized supply lines rarely fail all at once, which makes them easy to overlook until problems get worse. Corroded pipes not only raise the risk of leaks but also send rust particles downstream. This sediment can clog aerators, showerheads, and even appliances like water heaters. Over time, you can expect more frequent maintenance and possibly premature failure of fixtures. For issues related to rusty water damaging appliances, our water heater services cover cleaning and replacement for older tanks.
Basement leaks and water stains can also point to problems with both supply and drain lines, especially in homes with cast iron or clay tile drains. If your home is experiencing regular backups or slow drains, check out our drain cleaning and sewer line services for more details on how we address those issues.
