Precision External Caulking Across Melbourne
Protecting Melbourne homes and commercial buildings from water ingress and weathering with precision-sealed joints, facades, and window perimeters.
External caulking seals joints, gaps, and seams on the outside of a building, around windows, doors, facades, and expansion joints, to keep water, wind, and pests out and protect the structure beneath. This matters for homeowners and commercial property managers who notice cracked, shrinking, or missing exterior sealant, or who are completing a new build or renovation.

What Affects the Cost of External Caulking?
Facade size, access, and scope of work are the main drivers of cost, not a flat per-metre rate.
Cost for external caulking jobs is driven by the size of the facade or number of joints being sealed, how accessible those areas are (ground-level windows versus multi-storey scaffolding or EWP access), the condition of existing sealant that needs removing first, and the sealant product specified for the job's weather exposure.

External Caulking FAQs
What is external caulking and why does my property need it?
External caulking involves applying a flexible weatherproof sealant to joints, gaps, and seams on the outside of a building, around windows, doors, facades, and expansion joints. It keeps water, wind, and pests out, protecting the structure beneath. Without it, even small gaps can allow moisture penetration that leads to costly damage over time.How do I know if my external caulking needs replacing?
Common signs include caulk that is cracking, shrinking, peeling away from the surface, or has gaps forming along joints. Discolouration or mould growth around sealed areas can also indicate the sealant has failed. Trueline's team can assess your property and advise on what needs attention.Do you handle both residential and commercial external caulking?

The duration depends on the size of the property and the scope of work, a single residential window line may be completed in a few hours, while a multi-level commercial facade will take longer. After an initial site assessment, Trueline can give you a clearer timeframe for your specific job.
