Professional caulking, sealant replacement and joint sealing for residential, strata and commercial buildings across Sydney.
Buildings expand and contract with every temperature change. Joints that cannot flex with this movement crack, open and allow water entry at every level.
Sealant that has lost flexibility cracks along its length — no longer watertight and actively allowing water entry at every crack.
Sealant pulling away from one or both sides of the joint — adhesive failure means water can run freely behind the joint face.
Sealant shrinking back from joint edges leaves visible gaps at both sides — a common failure mode on older or incorrectly specified products.
Dark staining running down the facade directly below a joint line is direct evidence of active water entry through failed sealant.
Mould or organic growth along a sealant bead indicates persistent moisture retention and active degradation of the sealant surface and substrate.
UPKEEP provides rope access painting, facade maintenance, concrete repairs, remedial works, sealant replacement, soft washing, window cleaning, roof cleaning, anchor testing and building inspections throughout Sydney.
Whether a project requires rope access, EWP access, ladders or ground-based access, we use the safest and most efficient method to complete painting, remedial and maintenance works.
The terms are often used interchangeably. Caulking typically refers to filling gaps and joints with a flexible compound to prevent air and water infiltration. Sealing refers more broadly to the application of sealant products to joints, penetrations and interfaces. In practice both involve the same materials and process — the distinction is largely semantic.
The most common causes are UV degradation, thermal movement beyond the sealant's design capacity, three-sided adhesion from missing backing rod, missing primer, incorrect product selection, and age. Poor original installation is the single biggest contributor to premature sealant failure.
No. Painting over failed sealant hides the problem without fixing it. Water will continue to enter through the failed joint regardless of what is applied on top. The sealant must be removed and correctly reinstalled before any paint finish is applied.
We specify polyurethane and silicone sealants from leading manufacturers selected to match the joint type, movement requirement, UV exposure and substrate. We do not use one product for every application — correct specification is what separates a 10-year joint from a 2-year joint.
Yes. Rope access sealant work causes minimal disruption. Residents are notified in advance, access to the building is not affected, and most sealant programmes can be completed without any impact on daily building operations.
Standard polyurethane sealants last 7–12 years in typical conditions. Premium products can extend this to 15 years. High-movement joints, north-facing surfaces and coastal environments shorten service life. An inspection will give you a realistic picture of what your building's joints have left.
A backing rod is a polyethylene foam cylinder inserted into the joint before sealing. It controls the depth of the sealant, prevents it from bonding to the back of the joint — which would cause tearing when the joint moves — and ensures the correct sealant profile for long-term performance. Most failed sealant jobs are missing it.
Yes. We seal external facade joints, window perimeter seals, balcony and wet area joints, expansion joints, penetration seals and internal joints where required. The product and method varies by location and exposure.
All old sealant is mechanically removed. Joint faces are cleaned of contamination, dust and residue. Backing rod is installed to the correct depth. Primer is applied to both faces and allowed to cure before any sealant is applied. This preparation process is what most cheap contractors skip.
Our team holds a broad range of certifications and licences across the business including IRATA and SPRAT rope access qualifications, public liability and workers compensation insurance, First Aid, Police Checks, Working with Children, Height Safety System Installation and Testing, EWP over 11m, Asbestos Awareness, Confined Spaces, and Painting and Decorating trade qualifications. Every job is staffed with the right people for the scope of work.
