Sydney Seal Masters
Nasser personally walks homeowners through the coating process before starting — multiple reviewers say this made a visible difference to the final result.
The small review count limits how much you can extrapolate, but every single review in our sample is five stars with no trajectory dip, covering a range of surfaces from rooftop polyurea to studio floors — suggesting this isn't a one-trick operation. If you're planning a garage, driveway, patio, or waterproofing project, it's worth asking them specifically about their product brands and prep machinery, since two reviewers independently raised those points as reasons the finish held up.

About Sydney Seal Masters
Nasser and Yvonne run Sydney Seal Masters as a hands-on duo, with Nasser handling the technical application work — including epoxy flooring, polyurea spray systems, and surface resurfacing — while Yvonne appears consistently in reviews as the communications and coordination anchor. Reviewers specifically call out Nasser's ability to explain the process and prep work clearly before starting, which matters for coatings jobs where surface preparation is the difference between a floor that lasts and one that peels. Their project scope spans garages, driveways, pool surrounds, patios, rooftops, and studio fit-outs, making them one of the few operators in this category who cross between decorative epoxy and functional waterproofing membranes like polyurea. Multiple customers mention the transformation from stained or tired surfaces to glossy, showroom-quality finishes, with one noting completion two days ahead of schedule — a meaningful data point for renovation timelines. The company has been operating for just over three years as a registered entity, uses what reviewers describe as state-of-the-art machinery for preparation, and brings top-quality coating products to site. They appear best suited to homeowners tackling a specific resurfacing or waterproofing project rather than emergency leak callouts — the work they're praised for is planned, thorough, and detail-focused.
Best for: planned garage epoxy flooring projects wanting a showroom finish, rooftop or patio waterproofing using polyurea systems, and homeowners who want the applicator to explain the process before work begins.

What types of surfaces can Sydney Seal Masters coat or waterproof?+
Reviews mention garages, driveways, patios, pool surrounds, rooftops, and studio floors — so they work across both decorative epoxy applications and functional waterproofing membranes like polyurea. One customer specifically had a rooftop polyurea spray applied, which is a different skill set from standard floor coatings. If you have an unusual surface or layout, it's worth describing it upfront when you request a quote so Nasser can advise on the right product.
What do customers say about pricing and quotes from Sydney Seal Masters?+
One reviewer specifically calls out 'very reasonable quotes' and honest communication around costs. No reviews mention pricing disputes or unexpected charges. With only 16 total reviews to draw from, this is a limited data set, so it's still worth asking for an itemised quote that separates labour, surface prep, and materials — especially since prep machinery and product quality are factors reviewers credit for the end result.
How does the preparation process work before the coating is applied?+
Multiple reviewers highlight the preparation stage as a key reason for the quality finish — one notes that Nasser used 'state of the art machinery' to prepare the surface before applying product. Nasser is described as taking time to explain all aspects of the process before starting work, so you can expect a walkthrough of what will happen rather than just showing up and starting. Good prep is what separates coatings that last from ones that peel, so asking about the specific prep steps for your surface type is a smart question.
Are Nasser and Yvonne the ones who actually show up to do the job?+
Based on the reviews available, yes — Nasser and Yvonne appear to be the primary operators who attend jobs directly, which is consistent with this being a smaller owner-operated company. Reviewers name them both on individual jobs across garages, patios, rooftops, and studios. One reviewer even describes them as a 'dynamic duo,' suggesting they work the jobs together rather than sending subcontractors.
Does Sydney Seal Masters work outside Sydney's inner suburbs?+
The business is based in Melonba, NSW, which is in the outer north-west of Sydney. Reviews don't specify the range of suburbs they service, so it's not possible to confirm from available data how far they travel. If you're outside the greater Sydney area or in a specific suburb, confirm their travel range directly when you enquire — some coating businesses charge travel fees for longer distances.
