A lot of homeowners in Kankakee County call us up asking for a quote on getting the outside of their house cleaned. Somewhere in that conversation, two services almost always come up together: house washing and window cleaning. Most folks figure they're basically the same thing, maybe just different words for the same job. They're not. These are two separate services with different goals, different equipment, and different outcomes. Understanding the distinction helps you make a smarter decision for your home and your budget.

At Green Pro Services , we do both. We're based right here in Kankakee and serve homeowners across Bourbonnais, Bradley, Manteno, New Lenox, Frankfort, and Mokena. This article breaks down exactly what each service involves, when you need one versus the other, and why combining them is often the smartest move you can make for your home's curb appeal.

What Is House Washing?

House washing is a full exterior surface cleaning of your home's siding, soffits, fascia, and sometimes foundation walls. The goal is to remove the biological growth and environmental buildup that accumulates on your home's outer shell over time. We're talking about algae , mold , mildew , oxidation, dirt, pollen, and spider webs that cling to the surface of your siding. This isn't just a cosmetic problem. Left alone, these organisms can degrade paint, eat into vinyl, and trap moisture against your home's structure.

The most effective method for house washing on most residential siding is soft washing. Soft washing uses low-pressure water combined with a specialized cleaning solution, typically a diluted sodium hypochlorite mix paired with a surfactant. The solution does the heavy lifting, penetrating into the surface and killing biological growth at the root rather than just blasting off the top layer. Once it dwells for several minutes, the surface is thoroughly rinsed clean at low pressure.

High-pressure washing, on the other hand, can force water behind siding panels, strip paint, and void manufacturer warranties on vinyl siding products. Green Pro's house washing service uses the right pressure for the right surface every time. That means your siding stays intact, your paint lasts longer, and the results hold up for a year or two rather than a few weeks.

What House Washing Covers

House washing does not clean the glass on your windows in any meaningful way. It may rinse off surface dust from the panes, but that is not its purpose, and a house wash alone will leave your window glass streaked and covered in cleaning solution residue if not followed up properly. That is where window cleaning comes in.

What Is Window Cleaning?

Window cleaning is a detail-focused service aimed specifically at the glass, frames, sills, and tracks of each individual window on your home. The objective is crystal-clear, streak-free glass and fully clean window components from top to bottom.

Professional window cleaning goes well beyond spraying glass and wiping it with a squeegee. A trained window cleaner removes the screens, cleans the frame and sill, scrubs the glass with a surfactant solution using a professional-grade scrubber, and then pulls the solution off with a precision squeegee to leave a streak-free finish. Hard water deposits, mineral staining, paint overspray, and oxidation on the glass itself require specific techniques and sometimes dedicated products to fully remove.

The difference in scope is significant. Window cleaning addresses the entire window system, not just the visible pane. Dirty tracks can affect how well windows open and close. Clogged sills trap moisture that promotes rot in wood frames. Screens caked with debris reduce airflow and trap pollen against the glass. A thorough window cleaning catches all of this, not just the shine on the glass.

Side-by-Side: How They Compare

Which Service Do You Actually Need?

The honest answer for most Kankakee County homeowners is: both, ideally done together. Here's why.

When we soft wash a home's siding, overspray and rinse water inevitably run across window glass. If windows haven't been cleaned afterward, they'll dry with streaks, solution residue, or mineral deposits. Conversely, if you have your windows cleaned but your siding is still covered in green algae and black mold streaks, clean glass won't do much for curb appeal. The two services are complementary, and scheduling them together on the same visit is more efficient, usually more cost-effective, and produces a dramatically better overall result.

That said, there are situations where one service makes more sense on its own:

Choose house washing alone when: Your siding shows obvious green algae, black streaks, or mildew staining. You're getting your home ready to paint and need a clean surface first. Your gutters have heavy tiger-striping. It's been two or more years since the exterior was cleaned.

Choose window cleaning alone when: Your siding is still relatively clean but your windows are heavily spotted or streaked. You're hosting an event or preparing for a showing and want sharp-looking glass quickly. You want to improve natural light inside the home without a full exterior cleaning job.

Do both together when: You're preparing your home to sell. You're coming out of winter and want a full spring refresh. Your home hasn't had any professional exterior cleaning in the past two years. Realtors in the Kankakee County area consistently note that a clean exterior is one of the easiest and most cost-effective ways to increase perceived value before a listing goes live.

Why Professional Service Beats DIY for Both

Both house washing and window cleaning look straightforward from the outside. In practice, both have real risks when done wrong.

Pressure washing siding with too much force can crack vinyl, drive water into wall cavities, strip caulking around windows and doors, and cause water intrusion issues that lead to mold inside the walls. Most consumer-grade pressure washers are set far too high for siding cleaning. Soft washing requires the right chemical dilution, the right dwell time, and careful attention to protecting landscaping, screens, and window seals from the cleaning solution.

Window cleaning at height is a genuine safety risk without proper ladders, standoffs, and technique. Beyond safety, achieving a streak-free finish on glass requires the right tools and a practiced squeegee technique that takes time to develop. Most DIY window cleaning attempts leave smears, lint from paper towels, and soap film that attracts dirt faster than before.

Hiring a local, professional exterior cleaning company like Green Pro Services means the job gets done right, safely, and efficiently. Our team uses commercial-grade soft wash systems and proper window cleaning tools. We carry full liability insurance, which protects your home and you in the rare event something goes wrong. And because we do this every day, we're faster than a homeowner attempting it themselves over a full weekend.
