Frequently Asked Questions

Caulking is the process of sealing joints or gaps between different building materials to prevent moisture, air, and debris from entering. It also improves the appearance and durability of surfaces and is essential for meeting building compliance standards.

Caulking is not listed as its own category on the NSW Government's categories of building and trade work. NSW does require a contractor licence for residential building and trade work above a set value in labour and materials, including subcontracted work that forms part of a larger contract above that value. Whether that applies depends on the job, so ask any caulker how your work is covered and get the scope in writing.

Ask what the insurance covers and confirm it is current. Then get the scope in writing: which joints, which sealant for each, how much old sealant will be removed, and how the job is measured. Every Australian Caulking Experts applicator is fully insured, and we quote from plans, takeoffs, a site walk-through or photos.
