Cornelius Window, Gutter and Pressure Cleaning
Every review names Sam personally — and every customer says they're booking him again.
The pattern across those reviews is consistent: fast replies, shows up on time, and the physical results — particularly window cleans — match what he promises. With only 10 total reviews to go on, you can't draw strong conclusions about edge cases or how he handles complications, so it's worth asking him directly about what happens if a gutter job reveals underlying damage, and whether he covers your specific suburb if you're outside St Marys.

About Cornelius Window, Gutter and Pressure Cleaning
Sam Cornelius runs this sole-trader operation out of St Marys, handling window cleaning, gutter cleaning, and pressure washing for residential properties across the western Sydney area. What stands out from reading through the reviews is that Sam does the work himself — every review names him directly — so you're not booking a company and getting whoever turns up; you're getting Sam. Customers specifically note he works around their schedules, which matters if you're juggling a job or family, and at least one reviewer flagged feeling comfortable having him on the property while home alone — a practical detail that's easy to overlook when comparing quotes. His window cleaning work draws repeated comparisons to 'brand new' results, with inside-and-out cleans mentioned across multiple jobs. He's been operating for roughly 15 years, which gives him a track record well beyond what 10 Google reviews alone would suggest, and he's GST registered, meaning he can provide proper invoicing for landlords or property managers who need paperwork. Based on the review sample, he suits homeowners wanting a consistent, single-person operator for regular maintenance rather than a large crew job.
Best for: residential window cleaning with inside-and-out results, routine gutter clearing for homeowners wanting a consistent single operator, and property maintenance bookings where schedule flexibility is important.

Does Cornelius Window, Gutter and Pressure Cleaning work around your schedule?+
Multiple reviews specifically call out Sam's flexibility around the customer's availability. One reviewer noted he was 'ready to help and work around my schedule,' and another mentioned him responding quickly to enquiries before getting the job done. If you have specific timing constraints — school runs, work commitments — it's worth mentioning them upfront when you contact him. Reviews don't mention specific booking lead times, so ask him directly what his current availability looks like.
What areas does Sam cover from his St Marys base?+
The business is based in St Marys in western Sydney, but reviews don't specify exact coverage boundaries. As a sole trader operating for roughly 15 years, he likely services a reasonable radius around the area, but you'll want to confirm your suburb directly with Sam before proceeding — particularly if you're further out from western Sydney.
Does Sam do both inside and outside window cleaning?+
Yes — multiple reviews specifically mention inside-and-out window cleans. One customer described the results as looking 'brand new again' after years of dirty windows, and another said 'the job he did on my windows inside and out was amazing.' If you need only external cleaning or have specific access requirements (upper floors, skylights), it's worth discussing those details when you enquire.
What do customers say about Sam's pricing?+
Pricing comes up positively in several reviews, with customers describing him as 'great value for money' and 'well priced' relative to the quality of work. No reviews mention specific dollar figures, so you'll need to request a quote directly. Given he's GST registered, he can provide a proper tax invoice — useful if you're a landlord or need documentation for a rental property.
Is Sam reliable for repeat maintenance bookings?+
Several customers in the review sample explicitly mention planning to rebook — one even signed off with 'see you soon for gutter cleaning' after a window clean. The pattern across reviews points to a tradesperson customers trust enough to invite back, which is a meaningful signal for ongoing maintenance rather than one-off jobs. That said, with only 10 reviews available, there isn't a large volume of data to draw from, so asking Sam about his regular maintenance scheduling and availability is worth doing before committing to a long-term arrangement.
