Cost GuideUpdated July 13, 2026
For Highland Park homeowners, a sudden water bill increase catches your attention, and it should. Water bills in this area don't usually jump overnight unless something has changed inside your plumbing system. Most often, an unexplained spike signals a leak somewhere in the house or yard. That means wasted water, higher costs, and potential damage if you don't track it down quickly.
Why Older Plumbing Systems Leak
Much of Highland Park's housing stock includes homes built 50 to 100 years ago. It's common in these older houses to find galvanized steel or cast iron supply lines, and those materials are reaching the end of their service life. Over time, pipes corrode, especially with our Lake Michigan water's moderate hardness. Corrosion forms weak spots, pinhole leaks, and cracks, often hidden in walls, basements, or under floors.
Freeze-thaw cycles in our cold winters make things worse. When water inside exposed or poorly insulated pipes freezes, it expands, stressing the metal and sometimes causing splits. Clay-rich local soil doesn't help, as shifting ground around buried lines can also damage pipes. All of these factors raise the risk of leaks, which can run for months unnoticed if not inspected.
Common Sources of Hidden Leaks
Leaks aren't always dramatic. Many water losses happen quietly behind drywall or under foundations. Here's where we typically find trouble in Highland Park:
- Toilets: Worn-out flappers or fill valves can let water run constantly from the tank to the bowl.
- Faucets: Slow drips add up. A single dripping faucet can waste hundreds of gallons a month.
- Underground supply lines: Old or shifting pipes between the street and your home can leak, sometimes leaving no obvious wet spots due to clay soil absorbing small leaks.
- Basements: Cracked foundation plumbing or leaking water heaters can go unnoticed, especially in unfinished or less-used areas.
- Sump pits: Water-powered backup sump pumps sometimes get stuck on, constantly drawing in and ejecting water.
We often start with a close look at these problem areas during a leak detection and repair service call. Our crew uses pressure testing, inspection cameras, and moisture meters to narrow down the source without unnecessary wall or floor damage.
How to Spot a Leak Before It Gets Worse
Some leaks are easy for homeowners to spot, but others are subtle. Pay attention to these warning signs:
- Unusually high water bills when your usage habits haven't changed.
- The sound of running water when fixtures are off.
- Constantly running sump pumps or toilets that refill on their own.
- Soft spots, discoloration, or musty odors near floors and walls.
- Low water pressure, which can indicate a break in the supply line.
- Spots of mold or dampness in basements, especially after winter freezes.
If you see any of these, it's smart to turn off fixtures one by one and check if your water meter still counts up. A moving meter with everything off usually means there's a leak on your side of the line.
How We Track Down and Fix Leaks
Our team looks for both obvious and hidden water losses. In older Highland Park homes, we carefully inspect supply lines, especially those made from galvanized steel, for signs of corrosion or mineral buildup. With modern tools, we can often pinpoint leaks without tearing into every wall. For underground leaks, pressure tests and camera inspections help us locate the break. If you're dealing with aging supply pipes, a partial or full pipe repair and repiping may be the permanent solution.
If the source turns out to be a running toilet or leaking fixture, those parts can usually be swapped out, sometimes in under an hour. Problems with water heaters or sump pumps, which are common in basements here due to high water tables, might call for water heater services or sump pump assistance. For issues outside the house, like a broken main line, we may need to dig and repair or replace a section of pipe, especially if root intrusion or pipe settlement is the cause.
Prevention and Regular Plumbing Checks
You can avoid a surprise bill by doing a seasonal checkup, especially after winter. Insulate exposed pipes, test your sump pump before spring rains, and keep an eye on areas prone to moisture. Check your water meter for movement with all water off a few times a year. If you have an older house with original galvanized or cast iron lines, consider a plumbing inspection to get ahead of corrosion issues.
If you notice slow drains, don't ignore them, sometimes a clog can cause overflows or stress supply lines. We handle drain cleaning as well as leak repairs, giving you one place to call for all these problems.
What to Do Next If Your Bill Surges
If your Highland Park water bill spikes and you can't explain it with extra laundry, guests, or lawn watering, it's time to get a professional involved. Prompt leak detection prevents extra water loss and limits the damage to floors, drywall, and foundations. Many hidden leaks will only get worse with time, leading to more expensive repairs and possible mold or mildew issues.
