A town that grew fast and mostly recently
The Census Bureau counted 2,867 people in Whitestown in 2010 and 10,178 in 2020. Its July 1, 2025 estimate is 15,767. For 2020 to 2024 the Census reports 4,678 households, a 69.6 percent owner-occupied rate and a median owner-occupied home value of $373,500.
Those figures give no home age, so we will not claim one. They do show a town that added thousands of residents in a decade, which means a lot of newer houses. Our reading is that this shapes the calls, so expect water heaters, fixtures and drains more than failing old pipes.
Newer pipe, and what that does to the call list
A 2015 fact sheet from Whitestown Municipal Utilities said the town had replaced about 90 percent of its water and sewer system. It also described a 2.5 million gallon water tower, a new wastewater treatment plant under construction, and called Whitestown the fastest-growing community in Indiana at that time.
That is a statement about town infrastructure, not about your house, and we treat it as an inference. If the mains are newer, we expect fewer calls caused by collapsed or corroded public lines. What remains is mostly inside the house and on the private side, such as the water heater, traps, fixtures and appliance hookups.
Before We Arrive
While you wait for us, these steps limit damage and help us work faster.
Find and close the main shutoff
It is usually where the water line enters the house, often in a basement or utility room. Turn it clockwise until it stops.
Stop using water and drains
If a drain is backing up, do not flush or run the sink, shower or washing machine until we look at it.
Turn off the water heater power
If a tank is leaking, shut off the electric breaker or set the gas control to off, and close the cold supply valve above the tank.
Move belongings and photograph the damage
Lift rugs and boxes off wet floors, and take pictures for your insurance claim.
Leave the house for a gas smell
Go outside and call the gas utility or 911 from there. Do not use switches or phones inside.
Plumbing emergency in Whitestown?
Call the 24/7 line. We answer nights, weekends and holidays.
When it is an emergency in Whitestown
Call right away for a burst pipe, a leaking tank, a sewage backup into the house, no water at all, or any smell of gas. Pipes that run through attics or garage walls can freeze in a cold snap, and indoor water damage spreads in a few hours.
Call us any time, day or night, weekends and holidays included. We will not promise an arrival time on the phone, because it depends on where we are, but we will tell you what to do first. Small drips and slow drains can wait for a daytime visit.
Water heaters come first
Newer houses do not mean newer problems forever, because a tank still wears out on its own clock. The U.S. Department of Energy lists storage tank water heaters at 10 to 15 years and tankless units at about 20. A pilot that will not stay lit, a tank that runs out fast or a puddle at the base is a call.
We repair what can be repaired and say so when it cannot. Our water heater repair page explains thermostats, elements, burners and relief valves. A tank leaking from its seam is finished, and that is a replacement.
Drains and sewer backups
Whitestown Municipal Utilities provides sewer and stormwater service for the town. If one drain in the house runs slowly, the clog is probably in that fixture's line. If several drains back up together, such as a basement floor drain or a first-floor tub, the problem is in the main line.
Our drain cleaning work uses cables and, when needed, a camera to see what is blocking the line. Grease, wipes and leftover construction debris are common culprits in any house. If the blockage sits at the street connection, we will say so and tell you who to call.
Faucets, toilets and everyday fixtures
A running toilet is the most common fix. The EPA says household leaks waste nearly 1 trillion gallons a year nationwide, and worn flappers and dripping faucets are common culprits. To test, add a few drops of food coloring to the tank and wait 10 minutes. If color reaches the bowl, the flapper leaks.
A dripping faucet at one drip per second can waste roughly 260 gallons a month, according to Indiana's Office of Utility Consumer Counselor. Our faucet repair page covers cartridges and seats, and a stuck stop valve under the sink is another quick repair.
Softener and filter questions
New owners often ask whether they need a softener. We tell them to test their tap and ask their water utility for its annual water quality report. Whitestown's New Residents page lists Citizens Energy Group for water and the town for wastewater, so that is where to ask for the report.
Our page on water softener and filtration explains softeners, carbon filters and reverse osmosis, and we do not recommend a system until your results are in.
Who to call for what in Whitestown
The town sends sewer and stormwater bills through Whitestown Municipal Utilities, and the New Residents page lists Citizens Energy Group for water, CenterPoint Energy for natural gas, and Boone Power and Duke Energy for electric. If you smell gas, the gas utility is the first call from outside the house.
For a high bill, Indiana's OUCC notes that a leak in the underground supply line is typically the customer's responsibility between the meter and the building. Our leak detection crews can trace it. If the street side is the problem, the utility handles it.
Yards, trails and outdoor faucets
Whitestown reports about 50 acres of parks and more than 12 miles of trails. That means lots of new landscaping, irrigation and hose bibs on the outside of newer houses. Disconnect hoses before winter.
The National Weather Service lists Indianapolis's average first freeze as October 26, and it is the nearest long-term station, not Whitestown itself. A hose left on an outdoor faucet can split the pipe inside the wall, and the leak shows up in spring.
