Utilities are typically 15–20% of gross revenue in a well-run laundromat. If yours are above 22%, you're overspending by hundreds or thousands per month — and the fix is usually operational, not mechanical.
Start with measurement
You can't reduce what you don't track. Pull your last 12 months of utility bills and break them into three categories: water, gas, and electric. Calculate each as a percentage of gross revenue.
Benchmarks for attended laundromats:
- Water: 4–6% of gross. Above 7% is a red flag.
- Gas: 6–10% of gross. Seasonal — peaks in winter for hot water heating.
- Electric: 2–4% of gross. Most stable of the three.
If you're above these ranges, the solutions below are likely to save you $200–800/month. Use the Utility Audit Tool to track your bills, flag anomalies, and compare against benchmarks.
Water: the biggest opportunity
Check for leaks. A single leaking fill valve can waste 200+ gallons per day. Walk your machines weekly and check for water on the floor, running sounds when machines are idle, or water meters that spin when nothing is running.
Check water pressure. High inlet pressure causes machines to overfill. Install pressure regulators if your supply exceeds 80 PSI. This alone can reduce water consumption by 10–15%.
Inspect fill valves. Worn fill valves don't close fully. They're $15–30 parts that can waste hundreds of gallons per month per machine. Replace them on a 2–3 year cycle.
Gas: it's about the hot water
Check your water heater temperature. 140°F is standard for laundromat use. Higher than that is wasting gas without cleaning benefit. Lower affects wash quality.
Insulate hot water pipes. Uninsulated pipes in a laundromat can lose significant heat. Pipe insulation costs under $100 and typically pays for itself in the first month.
Dryer maintenance matters. Clogged lint screens and restricted exhaust ducts make dryers run longer. Clean lint screens between every customer. Inspect and clean exhaust ducts quarterly.
Electric: the quick wins
LED lighting. If you still have fluorescent fixtures, switch to LED. The payback period is typically 4–8 months, and you'll reduce lighting electricity by 50–70%.
Timers on signage and exterior lights. Your neon sign doesn't need to run at 2 AM if you close at 10 PM.
HVAC scheduling. Your heating and cooling system doesn't need to run full blast during the overnight unattended hours. A programmable thermostat pays for itself immediately.
The seasonal pattern to watch
Gas bills typically spike 30–50% in winter months due to hot water heating demand. This is normal. What's not normal is a spike in any category during a month when it shouldn't move. A sudden jump in water costs in a stable-volume month means a leak or equipment issue — catch it fast.
One action this week
Walk your store and check for water leaks. Look under every machine. Listen for running water when nothing is in cycle. One fix could save you $100+ per month starting this week.
