Window Washing vs. DIY: What Oakland County Homeowners Need to Know

You've seen the trucks in Bloomfield Hills and Birmingham. The homeowner on NextDoor swears by their window washer. Your neighbor just had their house done and the difference is visible from the street. So why are you still dragging a ladder out every spring?

Most homeowners in Troy, Rochester Hills, and Lake Orion have tried the DIY route at least once. Some stick with it. Most don't — and the ones who don't have a consistent set of reasons. This article is for the homeowners who are deciding whether to hire a pro or keep doing it themselves.

What Professional Window Washing Actually Does

A professional window cleaning isn't just "cleaner than you get with a paper towel." It's a fundamentally different result. The difference comes down to three things: tools, technique, and time.

Purified water systems. Most residential window pros in Oakland County use pure water systems — no minerals, no residue. When the water evaporates, it leaves nothing behind. A garden hose or tap water leaves mineral deposits, especially on older windows with old glass and poorly sealed frames, which is common in Birmingham and Rochester's older homes.

Technician access. Pros have the equipment to reach second- and third-story windows safely, including interior glass on both sides. The average homeowner with an 18-foot ladder stops at what they can safely reach, which means the windows most visible from the street — the high ones — get neglected. Pros get everything.

Frame and track cleaning. A spray bottle and a paper towel cleans glass. It doesn't clean the window tracks, the inside channel, or the frame seals. Over time, debris builds up in those tracks and the windows start sticking, fogging, or showing condensation in ways that damage the seal. Pros clean all of it as part of a standard service.

DIY Window Cleaning: What Works and What Doesn't

Let's be honest about what DIY can achieve. If you have a single-story home in a flat neighborhood, an extendable pole system, a good squeegee, and two to three hours on a mild Saturday — yes, you can get your windows clean. Passable clean. Not pro clean, but passable.

Here's where DIY falls apart:

• Upper floors and interior glass. Reaching second-story windows from the outside requires ladders on landscaping or hardscaping that isn't always stable. Interior glass on both sides requires reaching across furniture, navigating blinds, and cleaning without streaking on surfaces you can't easily access. Professionals do both sides in one pass.
• Hard water stains. Rochester Hills and Bloomfield Hills homes — especially older ones with well water or older municipal systems — often have hard water deposits on exterior glass. A spray bottle of vinegar works on fresh spots. It doesn't touch established mineral buildup. Pros use formulated cleaning solutions that dissolve it.
• Screens. DIY window cleaning leaves the screens. Professional cleanings typically include removing, cleaning, and re-installing every screen. After one professional cleaning, screens that have been sitting untouched for a year or two look like new — and the glass looks new when the grime behind the screen isn't constantly re-depositing on it.

Making the Decision: Cost vs. Value

Professional window washing for a typical Oakland County home (2,000–2,800 sqft, two stories) runs $175–$325 depending on the contractor, the number of windows, and whether screens are included. Some contractors bundle window cleaning with gutter cleaning or pressure washing for a discount.

Here's a realistic cost comparison:

For single-story homes with fewer than 20 windows, DIY is genuinely a reasonable choice. For anything larger — or any home with two stories — the math usually favors hiring a pro, especially when you factor in ladder risk and the cost of supplies you keep buying every spring.

How to Find a Good Window Washer in Oakland County

The bar for "professional window washer" is low in some markets — anyone with a ladder and a spray bottle can call themselves one. Here's how to filter:

• Ask about purified water systems. Anyone using tap water and paper towels is closer to DIY with a longer reach. Purified water systems (DI or RO filtered) are the baseline for professional-grade results.
• Confirm screen removal is included. If they charge extra to remove and re-install screens, they're padding the invoice. Screen cleaning should be part of a standard residential window washing.
• Check reviews for streak reports. Streaking is usually a technique problem — bad squeegee use, using the wrong solution, or not drying properly. One or two streak complaints in reviews is normal. A pattern of streak complaints means move on.
• Ask about exterior-only vs. full-service. Some contractors quote low by quoting only exterior glass. Interior glass on both sides requires more time. Confirm what's included before you book.
