Question 1

Do you clean inside and outside?

Accepted Answer

Yes, our professional window cleaning service covers both the interior and exterior of every window as standard, ensuring a complete result on every visit. We also clean frames, sills, tracks, and fly screens, which are often neglected but make a significant difference to the overall finish. Tracks in particular accumulate dirt, dust, insects, and mould — especially in coastal areas like the Central Coast and Newcastle where salt and humidity accelerate buildup. The result is crystal-clear glass with spotless surrounds that improve the overall look and feel of your property, whether it is a residential home, strata building, or commercial premises.

Question 2

How do you reach high windows?

Accepted Answer

We use professional water-fed pole systems with purified water that can reach windows up to four storeys from the ground without scaffolding or ladders. This method is safer, faster, and delivers a streak-free finish because purified water leaves no mineral residue as it dries. For buildings above four storeys or with complex access requirements, we assess the site and recommend the safest approach. Our team is fully trained in working at heights and DSK carries $20M public liability insurance for every job.

Question 3

How often should windows be cleaned?

Accepted Answer

For residential properties, we recommend professional window cleaning every three months to maintain clarity and prevent the buildup of salt residue, airborne pollution, and hard water staining that dulls glass over time. Commercial premises such as shopfronts, offices, and medical centres generally benefit from monthly window cleaning to maintain a professional, welcoming appearance for customers and clients. Properties in coastal areas like the Central Coast, Lake Macquarie, and Newcastle often need more frequent cleaning due to salt spray carried by onshore winds. We can set up a recurring schedule at a frequency that suits your property type and budget, with reminders sent before each visit.

Question 4

Do you clean after construction or renovation?

Accepted Answer

Yes, post-construction window cleaning is one of our specialist services and a common add-on to our post-build cleaning packages. We remove paint splatter, cement residue, plaster dust, silicone smears, sticker residue, and adhesive marks using professional-grade scraper tools and solvents designed specifically for glass. Construction debris can etch permanently into glass surfaces if left untreated for too long, so we recommend scheduling window cleaning as soon as the build or renovation is complete. We work alongside builders across Sydney, the Central Coast, and Newcastle and can coordinate timing with your project schedule to ensure windows are pristine for handover.

Question 5

Are you insured?

Accepted Answer

Yes, DSK Cleaning is fully insured with $20 million public liability coverage that applies to all window cleaning work, including high-access jobs on multi-storey residential and commercial buildings. We can provide a Certificate of Insurance on request, which is commonly required by strata managers, commercial property owners, and builders before we commence work on their properties. Our team is also covered by workers compensation insurance, ensuring you have zero liability exposure. This level of coverage gives property owners, facility managers, and strata committees complete protection and peace of mind, especially for multi-storey buildings or complex access situations that carry inherent risk.
