If you’re thinking about starting a home service business — pressure washing, painting, landscaping, anything where you show up at someone’s property — there are problems no one warns you about. In Episode 2 of the Hose & Hustle podcast, Mike and Monica Dingler open the playbook on the messy parts: difficult clients, equipment failures, property damage, and the kind of customers who can sink your business.
After 16+ years of running Firehouse Power Washing, here’s what they wish someone had told them.
The Two Types of Clients: Labradors and Wolverines
Inside the Firehouse office, two pictures hang on the wall: a golden Labrador and a snarling Wolverine. They represent the two kinds of clients you’ll meet in any home service business.
The Labrador client submits their request, approves the quote, puts their card on file, gets out of your way, leaves a five-star review, and refers you to their neighbors. They’re customers for life.
The Wolverine client is unhappy with their life, and nothing you do will change that. Even if you wash 100% perfectly, they’ll still find something to complain about — because their unhappiness has nothing to do with your work.
“A Wolverine client is someone who’s unhappy with their life and nothing you say or do is gonna change that. They’re unhappy as a person — so they’re going to be unhappy as a client.”
— Mike Dingler
Why HOA Letters Send Wolverines Straight to Your Inbox
A surprising number of Wolverines come from HOA violation letters. The HOA tells the homeowner: “Your roof is dirty. Your house is dirty. Your concrete needs cleaning. Get it done by this date or pay $25/day.”
These clients don’t want to hire you. They’re forced to spend money they didn’t plan to. That resentment shows up at your door — and you have to be methodical about how you communicate (text-only documentation, clear scope, no surprises).
The #1 Red Flag When Screening New Clients
Mike’s answer is simple: if they refuse to put a card on file, they’re telling you they’re a catfish.
“If somebody won’t put their card on file, they are raising their hand and saying ‘don’t put me in your boat.’ That’s a red flag.”
Other red flags:
- They tell you not to use bleach (they’re trying to override your expert systems)
- They demand a specific day or workaround
- They want to negotiate the minimum price down
- They call multiple times before booking, looking for an angle
If a client can’t trust you to be the expert in your field, they’re not your client. You don’t ask the Delta pilot for his credentials before takeoff — and you shouldn’t accept that level of distrust from a homeowner either.
Property Damage: The Right Way to Handle “We Killed That”
It will happen. You’ll yank a hose around a corner and rip out a rose bush. You’ll spray a degreaser and strip the paint off the gutters. You’ll nuke a lawn with bleach runoff. The question isn’t if — it’s how do you respond when it does.
Mike’s protocol, drilled into every Firehouse technician:
- Don’t get defensive. Never say “that was already there when we got there.”
- Ask for pictures. Document everything in your CRM (Jobber, Customer Factor, etc.).
- Schedule an evaluation. Show up. Look at it. Take responsibility.
- Fix it yourself, not through a referral. People don’t want extra steps. They want solutions.
- Train on it. Make sure it doesn’t happen twice.
“The best way to get out of a problem is fixing the problem — not explaining it away, not offloading it on someone else.”
When a Firehouse tech sprayed degreaser on metal gutters and stripped the paint, Mike took a piece of the downspout to Home Depot, color-matched the paint for $20, painted everything back, and earned a five-star review and a customer for life.
The Insurance Truth Most Pressure Washing Owners Won’t Say Out Loud
Yes, you need general liability insurance. But you should almost never use it.
Here’s why: if you call insurance every time you damage a $4,000 lawn, your premiums skyrocket — or worse, your policy gets dropped. Insurance is for catastrophes ($97,000 lawsuits, major property damage). It’s not for the routine “I killed your azaleas with bleach runoff” moments.
Those, you handle out of pocket. You eat the cost. You learn from it. You keep your business reputable.
The Equipment Rule That Saves Your Day: “One Is None, Two Is One”
Mike learned this in SWAT training, and it shaped how Firehouse builds out every truck.
“If you need one, you actually need two. If you need two, you need three.”
Every Firehouse flat-bed has:
- 3 pressure washers (because you need 2 working every day)
- 3 spray wands (same logic)
- 2 surface cleaners (because you need 1 every day)
When something breaks down mid-job, the team keeps working. They don’t drive home, lose half a day, and apologize to the customer. They swap the broken machine and finish the job.
For a one-truck operator just starting out: always have a backup pressure washer on the trailer. The day yours won’t crank, you’ll thank past-you.
Roof Cleaning, Landscape Damage, and the “Sodium Thiosulfate” Save
Roof cleaning is the most damaging job in pressure washing. The chemicals that kill black streaks on shingles also kill grass, plants, koi fish, and anything alive in the runoff zone.
Firehouse mitigates this with:
- Sodium thiosulfate (“the Narcan for bleach”) — neutralizes residual chemicals in downspouts
- Pre-watering all bushes and grass before spraying the roof
- Leaving 5-7 rows of shingles above the gutter line unsprayed (gravity does the rest)
- Live monitoring of pop-up rainstorms — Mike will drive to a job site mid-day and dilute runoff with hundreds of gallons of fresh water if rain hits unexpectedly
“The solution to pollution is dilution.”
What Most New Pressure Washers Never Think About Until It’s Too Late
Landscape damage. Even doing everything right, you’ll occasionally lose plants. Be ready to:
- Replace expensive plants (Firehouse once paid $800 to replace a single adult cypress)
- Repaint front doors that get bleach mist (especially semi-transparent stained doors)
- Touch up oxidized siding with matched paint from Home Depot
- Document every incident with photos before leaving the job site
If repainting one section of a house costs less than half the job total, just do it. That’s the rule.
Final Word: Be Morally and Ethically Superior
“There’s people that will rip your business off. You have to be okay with that. You have to be morally and ethically superior to that. Where a lot of business owners fall short is they get in the ditch with that pig — and you don’t fight a pig in the ditch, because you’ll get dirty and the pig likes it.”
Run a clean operation. Document everything. Screen aggressively. Fix problems before they become reviews. Keep your insurance for catastrophes only. And remember: every Wolverine you avoid is a Labrador you have time to serve.
