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…
