Tips And TricksUpdated July 10, 2026
Many Libertyville homes are over 50 years old, so bathroom remodels often uncover aging plumbing or hidden issues. Skipping the planning phase for pipes, drains, and fixtures can lead to leaks or expensive change orders halfway through the project. Our team has seen how proper plumbing preparation keeps remodels on track and avoids headaches down the road, especially in houses with historic fixtures or original galvanized pipes.
Why Older Libertyville Homes Need Extra Attention
The mix of historic and modern houses in Libertyville means plumbing systems can range from old cast iron and galvanized steel to newer copper and PEX. Corroded pipes in these older homes may be hidden behind tile or walls until demolition starts. Lake Michigan water is moderately hard, which leads to scale buildup and reduces water flow, especially in older galvanized lines. Winter freeze-thaw cycles in Lake County can also leave pipes weakened or prone to leaks. It's wise to get a thorough assessment before you start tearing out walls or floors.
Know What's Behind Your Walls and Under the Floor
Before any demolition, you'll want to answer a few key questions:
- Are your water supply lines copper, galvanized steel, or PEX?
- Is any of the drain or vent piping cast iron or clay, which can crack or clog?
- Will your existing main water line support the new layout or extra fixtures?
- Are there signs of past leaks under the subfloor or behind the drywall?
- Is the bathroom's venting up to current plumbing code?
A plumber can check for corrosion, leaks, and insufficient sizing. If your home still has galvanized pipes, this is the time to consider pipe repair and repiping for better water pressure and reliability.
Drainage and Sewer Considerations
Drain lines in Libertyville's older properties can be cast iron, which tends to rust from the inside, narrowing pipes and causing slow drains or blockages. Clay drain tiles aren't uncommon in historic homes and can collapse or shift with the area's clay soil and water table. Checking drains for cracks or buildup now prevents future backups after a fresh remodel. Upgrading old P-traps and adding new cleanouts where possible keep maintenance simple.
If you're moving major fixtures or adding a shower or soaking tub, the existing sewer line may need changes. You can learn more about rerouting or repairing waste lines on our sewer line services page.
Upgrading Water Heaters and Supply Lines
Many bathroom remodels include new soaker tubs, double vanities, or multi-head showers, all of which can strain older water heaters. It's smart to check if your current heater can handle the increased demand, especially if it's more than 10 years old or if you're switching to a larger tub. We recommend reviewing your options at our water heater services page when planning a bathroom overhaul. A new unit might prevent lukewarm showers and poor flow for years to come.
During remodels, access is easier, so replacing aging supply lines or installing a thermal expansion tank can protect your pipes from future damage. This is especially relevant in areas prone to pressure swings or thermal stress from Lake County winters.
Fixture Choices and Installation Tips
New faucets, toilets, and showers often have different mounting requirements or water pressures compared to older fixtures. Some eco-friendly or high-efficiency models require specific supply sizes or valves. Double-check rough-in dimensions before ordering anything to avoid costly changes. We handle the full range of faucet and fixture installations to match your design, but getting the details right early saves time and money.
For those considering a new garbage disposal or specialty shower, check load capacity and drain slope. Modern codes may require backwater valves or updated traps, especially if you're altering the floor plan.
Preventing Leaks and Protecting Your Investment
No one wants to finish a remodel only to find hidden leaks weeks later. It's important to pressure-test all new lines, verify water-tightness of joints, and inspect for slow drips under sinks or behind tile. Where mold risk is high, especially near the Des Plaines River or lakes, waterproofing and leak detection catch issues early. Our leak detection and repair services spot problems before they cause expensive water damage.
- Test water pressure and flow after rough-in is complete
- Insulate pipes to guard against cold snaps
- Use shutoff valves at every fixture for quick isolation
- Check slope and venting of every new drain
- Seal all floor and wall openings against moisture infiltration
Planning these steps early makes the difference between a smooth renovation and a costly do-over.
