Why it matters here

Salt air is relentless on coastal glass

Living near the ocean is one of life's great pleasures — but salt, sand and humidity are hard on your windows. Left alone, salt residue etches and dulls the glass permanently. What starts cosmetic becomes costly. Here's what a regular professional clean protects:

Keep your views & your light

Clean glass brightens interiors with natural sunlight and keeps that ocean outlook the way it should be — clear, not clouded by salt and smudges.

Protect the glass itself

Salt, bird droppings and tree sap corrode and stain. Regular cleaning lifts them before they etch — extending the life of your windows and avoiding early replacement.

Warmer, more efficient rooms

Grime blocks sunlight. Clean windows let more warmth in, easing reliance on artificial lighting and heating — and keeping frames, tracks and seals healthy too.

For homes on or near the water we suggest a clean once or twice a year; further back, every 12 months usually does it. We'll help you land on the right rhythm for your place.

FAQs

Window cleaning on the Northern Beaches — common questions

How often should I have my windows cleaned?
For homes directly on or near the water, we suggest once or twice a year because of salt-air build-up. Further from the beach, every 12 months is generally enough. We're happy to help you work out the right schedule for your property.
Can you clean high or hard-to-reach windows?
Yes. Our water-fed pole system reaches up to four storeys with no ladders or scaffolding — safer for our team, and far less disruptive for you and your garden.
Do you clean inside and out?
We do. We'll clean windows inside and out as needed for a complete, streak-free finish.
Do you use chemicals on the glass?
Our Advanced Ionic Zero System needs no chemicals at all — just ultra-pure water. For interior glass we use gentle, streak-free solutions that are safe for your home and family.
Are you insured and police checked?
Yes — we're fully insured for public liability, and every member of the team has completed a National Police Check and a Working with Children Check.
Do I need to be home during the clean?
Not necessarily, though it helps for any specific instructions. If you'd rather not be there, we can arrange access in your absence.
How much does window cleaning cost?
It depends on the size of your property and the number of windows. Try our instant online quote tool for a price in under a minute, or send your details and we’ll confirm an exact figure — always obligation-free.
What payment methods do you accept, and is there a guarantee?
Bank transfer, credit/debit card and cash, with an invoice for every job. And yes — if you're not completely happy with the results, let us know and we'll make it right.
