What the Hell Should You Charge for Window Cleaning Fees? (Spoiler: You’re Probably Leaving Thousands on the Table)

Look, I’ve been in this game for 25 years, and if I had a dollar for every window cleaning owner who told me, “I just charge a flat rate and hope for the best,” I’d have retired to a beach in Cabo by now. Here’s the truth: you’re not a charity. You’re running a business, and if you’re not layering on value-added service fees—real add-ons tied to extra labor, equipment, or risk—you’re bleeding money.

These aren’t junk surcharges; they’re profit centers with 85–95% contribution margin that fund your back-office staff without you having to sell one more damn job.

So what fees actually work? Let me break it down like I’m talking to a buddy over a beer:

• Trip/minimum charge: $35–$75. If I have to drive to your house and you’ve got two windows, I’m not losing money on gas.
• Screen and track cleaning: $3–$8 per window. You want those screens dust-free? That’s extra labor.
• Hard-water/mineral removal: $5–$15 per pane. That’s not a “nice touch”—that’s chemical and elbow grease.
• High-work or second-story surcharge: $25–$100. You think I’m gonna risk my neck for free? Hell no.
• Ladder/lift fee: $50–$250 when a 32-ft extension or boom lift is required. Equipment ain’t cheap.

Here’s the formula that’ll make you feel like a genius: Incremental Margin = Σ (attach rate × monthly jobs × fee × contribution margin %). Let me run a real example. Say you do 120 jobs/month.

Add a $45 minimum/trip fee at a 70% attach rate, screen cleaning averaging $22/job at 40% attach, and a second-story surcharge of $50 at 25% attach. That’s (0.70 × 120 × $45) + (0.40 × 120 × $22) + (0.25 × 120 × $50) = $3,780 + $1,056 + $1,500 = $6,336/month in add-on revenue.

At a 90% contribution margin, that’s ~$5,702/month straight to overhead—enough to fund a part-time office coordinator. The 2027 benchmark for residential window cleaning? Average ticket of $250–$450 with add-ons making up 18–28% of revenue at well-run shops.

If you’re below that, you’re leaving cash on the table.

Now, you need tools to model and charge these fees. Here’s the Top 10, no BS:

Enter your job count, layer in each add-on with attach rate and fee, and it spits out incremental revenue and contribution margin. Built for owners who suspect they’re under-charging but can’t prove it. Model three scenarios, pick the winner, push it into your booking platform. That’s why it’s number one.

1. Jobber – $39/mo (Core), $119/mo (Connect), $199/mo (Grow) as of 2027. Build line-item products so your $45 trip minimum shows up as a discrete line. Quoting templates and optional line items are gold for window work.

1. Housecall Pro – $59/mo (Basic), $149/mo (Essentials), $299/mo (MAX). Price-book management with upsell prompts—when a tech’s on site, the app surfaces “add hard-water removal.” Automated review requests and re-marketing compound your add-on revenue.

1. ServiceTitan – $300–$500+/mo per tech. Overkill for a solo operator, but for multi-crew shops doing $1M+, its dynamic pricebook and good-better-best presentation are gold. Reports isolate add-on attach rate by technician.

1. Workiz 💎 BEST VALUE – Free tier, then $225/mo (Standard), $300/mo (Pro). Scheduling, dispatch, invoicing, and call tracking for small crews. Custom line items and on-site card payments make capturing fees friction-free.

1. QuickBooks Online – $35/mo (Simple Start), $65/mo (Essentials), $99/mo (Plus), $235/mo (Advanced). Not field-service software, but the accounting backbone to track contribution margin and prove your 85–95% margins.

1. Square – No monthly fee on base plan, 2.6% + $0.15 per tapped card. Itemized invoices and free tier make it a sensible starter for fast on-site payment.

1. GorillaDesk – $49/mo (Basic), $99/mo (Pro) per route. Recurring job automation and per-service line items keep fees attached automatically. Automated reminders drive re-booking where add-on revenue compounds.

Bottom line: Stop treating window cleaning like a hobby. Charge the fees, model the math, and watch your back-office staff pay for themselves. If you want to geek out on the numbers, grab the free PULSE calculator—it’s your first stop before you commit a new price sheet.
