The Northern Beaches' trusted window cleaning specialists.
Built from the ground up right here on the Beaches — family-owned, fully insured, and genuinely local. The same friendly team, every time you book.
You deal with us — not a call centre.
We're a family-owned and operated window cleaning business serving homeowners and businesses across the Northern Beaches, Lower North Shore and North Shore of Sydney. Unlike the big franchise operations, you deal directly with us — the same professional team every time you book.
When you book Coastal Clear Windows, you're inviting someone into your home or business, and we take that seriously. Every member of our team has completed both a Working with Children Check and a National Police Check, and we're fully insured for your complete peace of mind.
The most advanced gear — and the old-school craft to match.
Our Ionic Zero System produces ultra-pure water at zero parts per billion (0ppb) — the gold standard in professional window cleaning. Paired with reach-and-wash poles, we clean every window on your property including frames, sills and fascias, and reach upper-floor glass with no ladders and no risk.
But we haven't lost the art. For the finishing touch we still use the traditional squeegee — where skill, angle and timing deliver a result no machine can replicate.
See how we work
One local team for the whole exterior.
Homes here face challenges that properties further inland simply don't — salt-air residue, coastal grime, and the wear that comes with living near the ocean. That's why we offer a full suite of exterior cleaning alongside the windows:
- Gutter cleaning — high-power vacuum and camera-assisted long-reach poles
- Solar panel cleaning — purified water, no chemicals, maximum panel efficiency
- Soft house washing — gentle removal of mould, algae and lichen
- Pressure cleaning — driveways, decks and pavers restored to their best

Our reputation speaks for itself.
With a 5.0-star rating across our verified Google reviews, our customers consistently highlight our professionalism, attention to detail and clear communication — and the genuine difference a proper clean makes to how a home looks and feels. We're proud to have earned the trust of families, strata managers, real estate agents and businesses right across the Northern Beaches.
