A bathroom remodel is a big investment for any Lombard homeowner, but the hidden plumbing can make or break the project. Upgrades to fixtures, relocating a shower, or even swapping out an old tub all depend on the condition and layout of your existing pipes. The homes in Lombard range from mid-century ranches to more modern builds, so what's in the walls and under the floors can vary a lot, and cutting corners often leads to leaks or clogs down the road.
Why Older Lombard Homes Need Extra Plumbing Attention
Many properties in the western suburbs of Chicago were built between the 1950s and 1990s. If your bathroom hasn't been touched in decades, you might be dealing with galvanized or cast iron water and drain lines. These materials are prone to corrosion and internal buildup, especially with Lombard's moderately hard municipal water. If pipes are brittle or reduced in diameter, new fixtures won't work as intended and drain blockages or pinhole leaks can develop soon after a remodel.
Another challenge is the area's frequent freeze-thaw cycles. Cold winters can stress older or poorly insulated pipes in exterior walls. Before you close up a new vanity or tile a shower wall, it's important to assess these lines and decide if upgrading to copper or PEX is required. Our pipe repair and repiping services address these problems before they become emergencies.
Drain Layouts and Slope Matter
Changing the location of a tub, toilet, or shower sounds easy on paper, but the drain layout underneath is key. Modern bathrooms use PVC drains with proper pitch for reliable wastewater flow. Older homes might have cast iron or even clay drains with bends and joints that blockages can form in. In Lombard, the clay-rich soil and high water table can accelerate shifting, leading to misaligned pipes and slow drains.
When we plan a remodel, we trace the path from each fixture to the main stack. Moving a toilet or shower usually involves opening the floor and re-pitching the waste lines. Unexpected issues like roots in the old drains or heavy buildup can pop up. Our crew often recommends a full drain cleaning or even sewer line inspection before finalizing the new layout so you don't end up with backups after your renovation.
Ventilation and Code Requirements
Bathroom plumbing requires proper venting to prevent slow drainage, gurgling, and trap siphoning. In some older Lombard homes, you may find undersized or improperly placed vents, or none at all. Modern codes call for vent stacks or air admittance valves at the right locations. If you're adding a double vanity or moving fixtures, we assess whether extra venting components need to be added. Otherwise, sewer gas smells or recurring clogs can become a nuisance.
We also make sure new work matches the area's plumbing code. This includes using the correct traps, shutoff valves, and backflow prevention where needed. Ignoring code updates can cost you in delays or failed inspections, especially in DuPage County.
Water Supply Considerations and Upgrades
Pressure and flow are the backbone of a comfortable remodel. Lombard's moderately hard water leads to mineral deposits in hot and cold supply lines over time. Old valves may seize or leak during fixture replacements. If you want rain-head showers or multiple body sprays, you may need to upsize supply lines and update the main shutoffs. We often find outdated or leaking shutoff valves, which are best swapped for modern quarter-turn models during the upgrade.
Fixture installation is another chance to spot possible trouble. Our team handles faucet and fixture installation with a close eye on supply hoses, pressure balancing, and sediment screens. With Lombard's water, keeping everything free of buildup is a must for reliable performance.
Common Plumbing Steps Before Remodeling
- Inspect visible and hidden supply and drain pipes for corrosion, leaks, or blockages.
- Check the main shutoff and individual fixture valves for accessibility and function.
- Assess if supply lines need upsizing to handle new fixtures or higher flow rates.
- Inspect and test vent piping for proper air flow and code compliance.
- Evaluate the water heater capacity and recovery rate if upgrading to larger tubs or multi-head showers. Water heater services can help avoid hot water shortages.
- Test all existing drains with a camera or auger for buildup, root intrusion, or improper slope.
- Plan for possible sump pit or pump adjustments if the remodel involves moving fixtures closer to basement or below-grade areas. Sump pump services keep everything dry in flood-prone soil.
