Every Painting Job in Your Area Is a Window Cleaning Job Waiting to Happen
Here's a scene I've watched play out hundreds of times over 25 years.
A homeowner gets their house painted. Walls look beautiful. Fresh, clean, crisp. The painter packs up and leaves. And the homeowner looks at the windows.
Paint specks on the glass. A smear in the corner of a pane. Overspray across the lower panel. And sometimes — worst of all — the painter already tried to "quickly clean it up" with a dry cloth or a razor blade, and now there are fine scratches across the glass that will never come out.
The homeowner needs help. They search online. They call a window cleaner.
Is that window cleaner going to be you — or someone else?
Post-paint window cleaning is one of the most underserved, consistently in-demand, and genuinely premium services in this industry. Painters are specialists at painting. They are not trained to clean glass. And when those two worlds collide without a skilled window cleaner in the picture, glass gets damaged and clients get frustrated.
This is your opportunity. But only if you have the skill to do it properly.
Why This Niche Exists — And Why It's Bigger Than You Think
Every single interior or exterior painting job — residential, commercial, new construction, renovation — creates post-paint glass cleanup work. That's not a small market. That's every painting job in your city, every single week, all year round.
Think about the volume of painting work happening around you right now:
- Homeowners repainting rooms and facades
- New builds finishing their interiors
- Commercial fit-outs refreshing office spaces
- Body corporates repainting apartment block exteriors
- Retail fit-outs between tenants
Every single one of those jobs ends with paint near glass. And in almost every case, no one has planned properly for who cleans the windows afterwards.
This is a referral pipeline that most window cleaners never tap. One good relationship with a painting company can send you two to three jobs a week — consistently, without advertising, without cold calling, without chasing.
The painters I know personally love handing this off. It's not their specialty. Cleaning glass isn't in their skill set or their toolkit. A window cleaner who can call a painting company and say "I specialise in post-paint cleanup — send me your clients and I'll make you look even better" is offering something genuinely valuable.
But here's the catch: you have to actually know what you're doing. Because post-paint window cleaning done wrong causes more damage than the paint itself.
What Paint on Glass Actually Does — And Why Technique Matters
This is the technical part that separates trained window cleaners from people who just show up with a squeegee.
When paint dries on glass, it bonds to the surface. Not loosely — it bonds. Water alone will not remove it. Scrubbing with a dry cloth pushes paint particles across the glass like sandpaper. That's not cleaning. That's scratching.
The type of paint matters enormously:
Water-based and latex paints are forgiving if you catch them early. Within a few hours of application, a damp cloth can remove most of it. Once fully cured — anywhere from a few days to a few weeks — you need careful scraping with the right tools, properly lubricated, at the correct angle.
Oil-based paints are a different job entirely. They cure hard, bond tightly, and require specific solvents applied correctly to release from glass without damage. Get the solvent wrong and you etch the glass. Apply it carelessly and you damage the surrounding frames and seals. This is where the skill gap between trained and untrained becomes painfully obvious.
The angle of your scraper is the detail that most people — including many working window cleaners — get wrong.
A razor blade held at 90 degrees to the glass will scratch it. Not might scratch it — will scratch it. The same blade at 45 degrees, on fully wet glass, with the right cleaning solution underneath — glides cleanly without marking the surface. That 45-degree angle is the difference between a result you're proud of and a client who now has permanent damage to their glass.
I've been called in to assess windows where a previous cleaner — untrained, well-meaning, but untrained — tried to remove post-paint residue the wrong way. I've had to explain to clients that the scratches are permanent. That's a conversation nobody wants to have.
Glass is not forgiving. Once it's scratched, it stays scratched.
This is why training matters before you take on this kind of work. The technique is specific and learnable — but it needs to be learned correctly.
The Premium Pricing Case — Built Into the Job Itself
Post-paint window cleaning is not a standard window clean. It's a specialist service. And specialist services command specialist rates.
Here's the logic your clients already understand:
A homeowner gets a standard window clean for a set price. That same homeowner, after a painting job with paint residue on every window, is looking at a job that takes longer, requires different tools, and carries real risk if done incorrectly. They know the difference. They expect to pay more.
In my experience, post-paint and post-construction cleans run anywhere from 50% to double the rate of a standard clean, depending on the scale of the job, the type of paint involved, and how long it's been sitting on the glass.
You're not charging more for the same work. You're charging appropriately for specialist knowledge. That's not upselling — that's pricing correctly.
And there's a cost comparison that closes every hesitation. A single standard double-glazed window panel costs $200-$400 to replace. High-end glazing costs significantly more. When a client understands that an untrained person using the wrong tool can permanently damage glass that costs hundreds of dollars per pane to replace — your specialist rate looks like exactly what it is: excellent value for proper protection.
How I Approach a Post-Paint Clean — Step by Step
This is the process I've refined over 25 years. Every step has a reason behind it.
Step 1: Assess before you touch anything. What type of paint is on the glass? Water-based or oil-based? How long has it been there — days, weeks, or months? Are there existing scratches from anyone who's already attempted removal? Is the surrounding frame still fresh enough that I need to protect it during the clean? This assessment takes a few minutes and shapes every decision that follows.
Step 2: Never dry-scrape. Ever. Before any tool touches the glass, the surface needs to be fully wet with a proper cleaning solution. Full lubrication. Every time. No exceptions. This is the single most important rule in post-paint work.
Step 3: Work the paint spots first. Using a professional-grade glass scraper at 45 degrees, with constant re-wetting, I work paint spots and overspray in smooth strokes. Small spots come off clean in one pass. Larger areas of overspray require patience and multiple passes. Rushing this step creates scratches.
Step 4: Treat stubborn oil-based paint separately. Targeted solvent application with a cloth — only on the paint, protecting the frames and seals. Allow it to work, then clean the solvent off completely with pure water. No chemical residue left on the glass.
Step 5: Full squeegee clean to finish. Once the paint is off, treat this as a standard clean — pure water system, streak-free finish, polished result. The job isn't done until the whole window looks better than it did before the painting started.
That last point matters. The painter made the walls beautiful. When you leave, the windows should match. That's what gets you a five-star review — and a referral to the next painting job on that painter's schedule.
Building the Referral Relationship With Painters
This is the business strategy that turns one skill into a consistent pipeline.
Most painting companies don't have a window cleaner they work with regularly. When their clients ask about the glass cleanup, they either try to do it themselves (badly), or they shrug and move on. Neither outcome is good for the painter's reputation.
You can change that for them.
The pitch is simple and genuine: "I specialise in post-paint and post-construction window cleaning. I have the tools and the training to remove paint from glass properly, without scratching. If you want to leave every job looking completely finished — walls and windows — I'd love to be your go-to cleaner."
That's not a sales pitch. That's a true statement and a real offer of value.
What you get in return:
- A consistent source of inbound referrals
- Premium jobs that are easier to price confidently
- A professional partnership that elevates your reputation
- Access to commercial and new-construction work through painting contractors
One strong relationship with a busy painting company is worth more than months of social media posts. But it only works if you can back the promise with the skill.
Master the skill first. The business follows. This has been true in every aspect of window cleaning throughout my career — and it's especially true here.
This Is Learnable. With the Right Training.
I want to be direct with you about something.
Post-paint window cleaning looks intimidating from the outside. Paint on glass, sharp tools, permanent damage risk, premium pricing pressure. That's a lot to navigate without guidance.
But the technique itself is learnable. The 45-degree angle, the lubrication, the assessment process, the solvent selection — these are specific skills that, once learned properly, become automatic. Muscle memory. The kind of confidence that means you show up to a post-paint job and know exactly what you're doing, even before you open your kit.
That confidence is what commands premium rates. Clients can feel the difference between someone who sort of knows what they're doing and someone who has done this a hundred times.
I've spent 25 years building that knowledge. The Orloffs training system exists to give it to you — without the 25 years.

FAQ
Do I need special equipment to do post-paint window cleaning? You need a professional-grade glass scraper with fresh blades, the right cleaning solution for lubrication, and appropriate solvents for oil-based paint. Most professional window cleaning kits cover the basics — but knowing how to use them correctly on paint-contaminated glass is the skill that matters most.
Is post-paint window cleaning more dangerous for the glass than regular cleaning? Done incorrectly, yes — dry scraping or using the wrong angle can permanently scratch glass. Done correctly with proper technique, it's a straightforward specialist service. The key is the 45-degree scraper angle, full lubrication at all times, and never rushing.
How do I price a post-paint window clean? Assess the job first — type of paint, coverage area, how long it's been on the glass, and the size of the windows. As a starting point, post-paint cleans typically run 50% to double the rate of a standard clean. The risk of glass damage and the specialist skill involved justifies the premium.
How do I approach a painting company about a referral arrangement? Keep it simple and genuine. Introduce yourself, explain that you specialise in post-paint window cleaning, and offer to handle their clients' glass cleanup so their jobs finish completely. Most painting companies will welcome the conversation — they don't enjoy dealing with paint-on-glass complaints.
Can beginners take on post-paint work, or is this for experienced window cleaners only? With proper training, beginners can absolutely learn this technique. The key is learning the correct process from the start — especially the angle, lubrication, and assessment steps — rather than trying to figure it out through trial and error on a client's expensive glass.
