The lovely lady who came over and completed a quote was friendly and professional and the 2 men who came and cleaned our windows were on time, professional, efficient and even chatted with my talkative 7 year old the whole time. Our windows have never looked better. 10/10. Looking forward to having them back regularly.

Mark and Reece were very friendly and professional and did a great job. My windows have never looked so clean! Will definitely be using their services again and have already recommended them to others. Thank you!

 Trustindex verifies that the original source of the review is Google. Friendly and easy to deal with. Nikki was so responsive when I requested a quote and to book. A great service and the windows were sparkling inside and out afterwards. Very reasonably priced and I have no hesitation to use Cassidy's again. Will also get them to clean (wash) the outside of the house and do my solar panels in the very near future. Thank you!

 Trustindex verifies that the original source of the review is Google. Hi all hope you are well. I recently had my kitchen and bathroom and windows cleaned by Cassidys and I couldn,t be happier with the results. They are extremely well mannered professional and hard working to say the least. When I entered my kitchen after the job was completed I thought I was in another kitchen as everything was so sparkling clean and smelled lovely and there was a lovely energy that I could feel ,so very nice indeed. So if you live in the Kurri Kurri area and need your house or windows cleaned give Cassidys a call you wont be dissappointed plus you will be giving a local business and local workers support , spend your money in your local community. Because if you dont we lose  good businesses like Cassidys from our town. I would have no hesitation in recommending  Cassidys for your house clean and or your windows. I will certainly be using them again. Please stay safe all. Regards Noel Bush. Lang Street Kurri Kurri.

Service Details – Commercial Building Windows

At Cassidy’s Cleaning, we understand that commercial buildings have unique cleaning requirements. High-traffic entrances, large glass facades, and multi-storey windows demand specialised equipment and techniques. That’s why we use professional-grade tools and eco-friendly solutions to deliver exceptional results for offices, retail centres, warehouses, and industrial facilities across Adelaide.

What’s Included in Our Commercial Service?

We offer both one-off deep cleans and ongoing maintenance contracts. Depending on your needs, we can include:

Interior & Exterior Glass Cleaning – Streak-free shine using premium squeegees and water-fed poles.
Main Entrance & Lobby Glass – High-visibility areas cleaned to perfection.
Frame & Sill Wiping – Fingerprints, cobwebs, and grime are completely removed.
Track Vacuuming – We vacuum and wipe window and door tracks for smooth operation.
DI-Ionised Water Rinse – Our purified water system eliminates mineral spots and leaves glass crystal clear – essential for large commercial facades.
Post-Construction Clean-Up – Removal of dust, paint splatters, and adhesive residues from new or renovated buildings.

Our Equipment & Technology

We use industry-leading tools from trusted brands like Unger and Gardiner:

Water-Fed Poles – Reach windows up to 4 storeys high (approx. 12 metres) from the ground.
DI-Ionised Water Tanks – Produce 100% pure water that dries naturally without streaks.
Soft Brushes & Squeegees – Gentle on glass but tough on dirt and grime.
Eco-Friendly Detergents – Biodegradable and safe for staff, customers, and the environment.

Quality Assurance

We don’t just clean and leave. Every job includes a final walkthrough with you (if you’re home) to ensure you’re completely satisfied. If anything isn’t up to standard, we’ll re-clean it immediately—at no extra cost.

💬 “Our goal is simple: leave your windows so clean that you forget the glass is even there.”

Why Commercial Window Cleaning Matters

Regular commercial window cleaning offers benefits beyond aesthetics:

✔️ Enhances corporate image – Clean, bright windows project professionalism.

✔️ Improves natural light – Reduces energy costs and creates a better working environment.

✔️ Extends glass life – Removes corrosive dirt, pollutants, and hard water stains.

✔️ Ensures safety & compliance – Regular maintenance prevents safety hazards.

✔️ Boosts employee productivity – A brighter, cleaner workplace improves morale and focus.

✔️ Attracts and retains tenants – Well-maintained properties command higher rents.
