Why the Two Sides Get Dirty Differently

Outside windows pick up dust, pollen, rain spotting, bird droppings, spider webs in corners, and (in NE Victoria) bushfire-smoke residue in summer. The dirt is mostly mineral — hard, gritty, sometimes baked on by sun. Outside cleaning needs more chemistry: a proper window solution with a slight detergent action, plus a squeegee to lift dirt without smearing.

Inside windows pick up cooking residue (especially anywhere near a kitchen), kid hand marks, dog nose prints, and a fine layer of indoor dust. The dirt is mostly organic and oily — softer, easier to remove, but smears more readily without the right technique. Inside cleaning needs less chemistry but more careful wiping.

Which Side Should You Prioritise?

If you can only afford one side, the answer depends on your light:

North-facing windows (lots of sun): outside matters more. Sun reveals every fleck of dust outside; inside dirt is harder to see in bright direct light.
South-facing windows (less direct sun): inside matters more. Diffused light reveals smudges and prints inside; outside dirt blends in.
Windows near a kitchen or BBQ: inside matters more. Cooking oil and grease build up faster than outside dirt for these windows.
Windows with a great view: outside matters more. The whole point of a view is the contrast at the glass plane — outside dirt destroys that.

“Hamish completed a large scale clean of our windows, big house with really tricky roof work etc. He did this safely and with expertise that I presume he learnt as an electrician. I highly recommend Hamish.”

Why Both Sides Almost Always Wins

The reason we recommend both sides on most quotes: the difference between “windows where one side was cleaned” and “windows where both sides were cleaned” is dramatic when you actually look through them. The eye picks up the discrepancy immediately — it looks like the window is permanently dirty even though one side is spotless.

Time-wise, doing both sides while we’re already on-site adds 30-40% to the cost — not 100%. You’re paying for the second-side cleaning chemistry and the additional cloth work; the call-out, the equipment setup, the access setup are all already covered.

Frequency Per Side

For most Wangaratta homes:

Outside: 2-3 times per year (spring, post-summer, before Christmas)
Inside: 1-2 times per year (spring + before Christmas usually enough)

Homes in dustier locations (near unsealed roads, paddock-adjacent, near construction) outside windows need 3-4 cleans per year. Homes with high-traffic kitchens or pets pressing their faces on the glass need inside cleans more often.

How You Get the Clean You Want

Window cleaning that’s done properly on both sides changes how a home looks and feels.

No pushy sales tactics. We have a friendly conversation, walk through your home, agree the scope room by room, and quote in writing. You move forward at your own pace. People choose Green Koala because we explain how the work will be done before we start — not after.

We’ll walk you through the room-by-room checklist so you’re not caught off guard by what’s included and what isn’t. We’ll explain the difference between cadences (weekly, fortnightly, monthly) so you know what each one costs and what each one delivers. And we’ll match what we do to what your home actually needs.

Our goal is straightforward. We want you to walk into a properly clean home — and feel that exact “this is what I wanted” relief — every visit.

Frequently Asked Questions

Is it worth cleaning only the outside of windows?

Only if your inside is genuinely clean. If both sides have visible dirt, cleaning just one side leaves the windows looking dirty regardless of how well you cleaned that one side. Best ROI is both sides at once.

How often should outside windows be cleaned in Wangaratta?

Two to three times per year for most homes. Spring (post-pollen), post-summer (post-bushfire residue), and before Christmas if you’re entertaining. Dustier locations push to four times per year.

How often should inside windows be cleaned?

One to two times per year for most homes. Homes near a busy kitchen or with pets that paw the glass might do three times. The dirt accumulates slower than outside but smears more obviously when neglected.

Does Green Koala clean both sides?

Yes — we quote both sides as standard and offer the inside-only or outside-only option separately. Both sides at once is the most cost-effective option.

How much does both-sides window cleaning cost?

For most 3-bedroom Wangaratta homes, $180-$280 for both sides depending on window count and access. Two-storey adds for the upper-storey access setup. Fixed price after a free walkthrough.
