MaintenanceUpdated June 9, 2026
Many homes in Lincolnwood have bathrooms that haven't seen an update in decades. Beneath those tiles and walls, original plumbing is often lurking, galvanized supply lines, cast iron or even clay-tile drains, and fixtures that have seen better days. Before you start your bathroom remodel, it pays to look hard at the pipes and plan carefully. Plumbing in older northern Chicago suburbs comes with its own set of risks, and skipping the prep can mean serious trouble after the dust settles.
Why Older Lincolnwood Homes Surprise Remodelers
The bulk of houses in Lincolnwood were built between the 1950s and 1970s. Back then, galvanized steel supply lines were common, and so were cast iron or even clay sewer branches. Over time, these materials corrode inside and out. In clay-heavy soil like we have locally, slow drainage or recurring clogs sometimes trace back to shifting, cracked, or root-intruded drains. Burying new tile or paint over these problems without fixing them puts your investment at risk.
We've seen that hard Lake Michigan water also leaves plenty of scale buildup inside old pipes, slowing flow and putting strain on water heaters. Combine that with the freeze-thaw stress of a real Chicago winter, and it's not unusual for an aging bathroom to have a few hidden vulnerabilities.
Start With a Thorough Plumbing Inspection
Before any demolition, a careful plumbing assessment saves headaches later. Our team checks all visible supply lines, shutoffs, and vent arrangements. We also examine drains for corrosion, improper slopes, or cracks. In many cases, we recommend a camera inspection for old waste lines. Small leaks or a joint packed with rust are best found up front, it's much easier to remedy a hidden problem now than after everything's tiled over.
Burst or leaking pipes are all too common after a remodel if the original plumbing is left untouched. We suggest reviewing our pipe repair and repiping service page for more on local issues with galvanized and cast iron lines.
Supply and Drain Line Upgrades to Consider
These are upgrades we advise for Lincolnwood bathrooms, especially if your home is mid-century or older:
- Replace galvanized supply lines with copper or PEX for reliable water pressure and fewer rust problems.
- Swap old shutoff valves, especially those on the toilet and sink. Original valves often corrode or freeze.
- Upgrade drains to PVC or ABS, which won't rust or scale up. If you have cast iron or clay-tile, inspect for tree roots or cracks.
- Check fixture spacing. New vanities, toilets, and tubs often need updated rough-ins to meet modern codes and fit properly.
- Install new traps and vents to prevent sewer gas and keep water flowing freely.
We also see a lot of demand for new shutoffs or pressure balancing valves. With our fixture installation service, we help make sure every connection is sized and placed correctly so you avoid leaks and code violations down the road.
Don't Forget About Water Heaters and Drainage
A bathroom remodel is a good time to check if your water heater is up to the job, especially in bigger families or if you're adding a larger tub. Decades-old units are common here in Lincolnwood homes, and hard municipal water takes its toll on tank interiors. Consider an inspection or upgrade, see our water heater services page for what to look for.
With local clay and loam soils and a moderate water table, Lincolnwood basements sometimes face drainage issues. If your remodel involves adding new basement plumbing, it's smart to evaluate the sump pit, check valve, and drainage routes. Our sump pump services cover common basement plumbing needs.
Warning Signs Before You Cover Up Old Plumbing
- Low water pressure, which could mean clogged galvanized lines
- Recurring sink or tub clogs, suggesting roots or blockage in old drains
- Corrosion, leaks, or moisture at pipe joints
- Sewer odors or slow-draining fixtures even after snaking
- Original or patchwork shutoff valves that don't fully close
Addressing these before the tile goes up can save you from costly leaks or repairs later. If you suspect a hidden problem, our leak detection and repair team can pinpoint trouble areas inside walls or under floors.
Plan Ahead for Code, Layout, and Future Proofing
Modern plumbing code is more stringent than when many Lincolnwood houses were built. Rough-in heights, clearances, venting, and accessibility now matter far more than in the past. If you're reworking your layout or moving a toilet, tub, or laundry, plan for rerouting supply and waste lines. We find many older bathrooms have venting that doesn't meet current standards, which can cause slow drainage or sewer gas issues.
It's wise to futureproof where possible, consider stub-outs or capped tees for possible upgrades down the line. If aging family members or resale value matter, think about installing blocking for grab bars or choosing comfort-height fixtures.
