Internal & External Window Cleaning

Professional Internal & External Window Cleaning

Clean windows transform the look and feel of any property. At Coasties Commercial Cleaning, we provide professional internal and external window cleaning for residential, commercial, and industrial properties across the Central Coast, Newcastle, Hunter Valley, and North Sydney to Hornsby.

Internal Window Cleaning: Our team cleans frames, sills, tracks, and glass using eco-friendly products. We remove dust, grime, fingerprints, and built-up residue for crystal-clear results every time. Every internal clean is thorough and detailed, leaving your windows spotless from the inside out.

External Window Cleaning: We use purified water-fed pole systems that deliver streak-free results without the need for scaffolding. Our high-reach poles extend up to 10 metres, allowing us to safely clean multi-storey buildings, warehouses, and hard-to-reach windows from the ground. The purified water system leaves zero residue, meaning windows stay cleaner for longer.

All our cleaning products are eco-friendly, biodegradable, and non-toxic — safe for your family, staff, and the environment. We follow strict safety protocols and use the latest equipment, with fully trained staff on every job. Whether you need a regular scheduled clean or a one-off service, we guarantee streak-free results on every window.
