Discover the most profitable upsells for window cleaners: from stainless-steel micromesh gutter guards and solar panel cleaning to Christmas light installations that produce $120k+ months. This guide reveals how to dramatically increase your revenue, boost your average ticket, and turn one customer visit into multiple high-ticket services without buying new equipment.
If you’re only selling window cleaning, you’re leaving thousands of dollars on the table every single day. Window cleaning gets you inside the door, but the real profits come from what you offer afterward.
Here are the TOP 5 upsells no one talks about that can turn a $500 customer into a $5,000+ customer the same day.
5. Solar Panel Cleaning
Solar panels get dusty fast, and dirty panels produce less energy. Homeowners know this, which makes this the easiest add-on for any cleaner.
The best part?
You already have the equipment:
Water-fed pole
DI tank / pure water system
Ladder
Average price: $150–$350
Time required: 15–25 minutes
Difficulty: Extremely low
Extra equipment: None
This upsell is quick, high-margin, and fits perfectly with any exterior cleaning route.
4. Gutter Cleaning
Gutter cleaning is one of the most requested exterior services, especially in fall and spring.
And again, all you need is the same ladder you already use for windows.
Average price: $150–$400
Time required: 20–40 minutes
Why it works:
Homeowners rarely check their gutters until there’s a problem. YOU pointing it out = instant booking.
If you need cash flow during slow months, this upsell fills your schedule instantly.
3. Stainless-Steel Micromesh Gutter Guards (The Hidden Gold Mine)
This is the upsell almost no window cleaners talk about and it’s easily one of the most profitable services you can offer.
We’re not talking about foam or plastic guards from Home Depot.
We’re talking about high-end stainless-steel micromesh gutter guards that block:
Leaves
Pine needles
Maple seeds
Shingle debris
Dirt & grit
These look clean, last decades, and give homeowners long-term peace of mind.
Here’s the wild part:
Charge: ~$19 per foot
Material cost: $3–$6 per foot
Example:
200 ft home = ~$4,000 install
Material cost ~ $800
Profit = extremely high
And the #1 reason customers say yes instantly?
Lifetime No-Clog Warranty
If their gutters clog again at ANY point in the future, you go fix it for free.
That means:
They never pay for gutter cleaning again
You provide a permanent solution
It builds trust and recurring referrals
You install it using the same tools you already own
This is the highest margin service on this entire list.
2. Screen Cleaning
A simple, small upsell that almost every customer says yes to once you explain it.
Dirty screens make freshly cleaned windows look dirty, and homeowners hate that.
Price: $3–$5 per screen
Booking rate: 80%+
Extra time: Minimal
Example:
20 screens = $60–$100 added instantly
Fast, easy, clean margin. And you use the same cloths, same tools, same workflow.
1. Christmas Lights ($120,000 December)
This is the #1 highest-ticket upsell for window cleaners, and it’s growing like crazy every year.
Why? Because professional Christmas lights are priced by roofline:
$8–$12 per foot
Most houses = 200+ feet
Every job starts around $2,000
Do just 2 installs per day, and you’re looking at a $120,000 month in December.
But here’s the part that makes this a true business builder:
👉 You own the lights.
👉 The customer is leasing your setup.
👉 You custom-cut every line.
So when December comes next year, guess who they call?
YOU.
You’re the only one with their design, their measurements, and their custom-cut bulbs — which means:
You’re the cheapest reinstall
It’s recurring revenue
It compounds every season
This is the closest thing to a subscription service in the exterior cleaning world.
Final Thoughts
Window cleaning is just the entry point.
These upsells use:
The same ladder
The same tools
The same customers
The same day
But they multiply your revenue 5x–10x without adding marketing costs or extra travel.
