About Cornwall Seal
What We Do
Cornwall Seal specialises in caulking and remedial caulking across Sydney. We work with residential, strata and commercial clients.
• Remedial caulking — cut out and reseal failed, cracked or mouldy silicone
• Bathrooms and wet areas — shower recesses, baths, vanities, floor-to-wall joints
• Kitchens and benchtops — stone, laminate and splashback joints
• Windows and doors — perimeter sealing internal and external
• Balconies and expansion joints
• New build and renovation caulking — full fit-out sealing
We use professional-grade neutral cure and mould-resistant sealants matched to the job
Our Guarantee
New caulking is backed by a 12-month workmanship guarantee — we control the prep and the product, so we stand behind it.
Remedial resealing is different. We're working over joints somebody else built, and we can't see what's behind them. So we assess each one, tell you honestly what we can and can't promise, and price it accordingly. No surprises either way.
