Sydney CBD & Inner City

One team carries this work from start to finish

Failed, missing or non-conforming sealant is a weatherproofing defect, and weatherproofing defects block close-out. M&M Services Group offers silicone services for projects in Barangaroo and inner Sydney: installation, inspection and repair of silicone joints, from small internal junctions to large facade expansion joints. Because the same team installs, inspects and repairs, the joint has one owner through the defects liability period rather than three parties pointing at each other.

Silicone work rarely travels alone, and it helps that one group also carries facade rectification, glass and surface protection — a mixed defect list in Barangaroo can be priced and delivered under a single subcontract. Joints are photographed as the work proceeds, with time-stamped images on OneDrive, and with 90+ staff across day and night shifts, caulking can run behind other trades without holding up the programme.

The local market

Working in Barangaroo

Barangaroo is a 22-hectare harbourfront renewal precinct anchored by the three International Towers, Crown Towers Sydney and Renzo Piano's One Sydney Harbour residential trio. Barangaroo Metro station opened in 2024, and Central Barangaroo — the precinct's final stage — continues the development pipeline. Facade typologies range from full-height curtain wall to sculptural podiums, with strict precinct-wide finish standards set by tier-1 builders and their facade partners.

Our Sydney crews also work in Millers Point, The Rocks, Sydney CBD, Dawes Point and the rest of inner Sydney.

Questions

What builders ask us

Yes — silicone installation, inspection and repair are available across Barangaroo and the broader region. Our crews handle everything from small internal junctions to large facade expansion joints, so we can price a scope of any size in Barangaroo. Our crews are based at Riverstone and work across Greater Sydney daily, so mobilising to a site in Barangaroo is routine.

Yes — inspection is one of the three things we do, alongside installation and repair. We can survey the existing sealant, report on what is failed, missing or non-conforming, and price the remedial work from that report. It gives your contract administrator a defined scope instead of an open-ended allowance.

Any of the three works. We price silicone scopes through formal tenders and RFQs, frequently bundled with facade rectification or glass work we also deliver, and we take direct enquiries at defect and DLP stage. Include joint schedules, drawings or survey photos and we will return a priced, staged response.

Joints are recorded as the work proceeds, with time-stamped documentation accessible to your team on OneDrive. Because installation, inspection and repair sit with one team, the record is continuous — what was installed, what was inspected, what was repaired — which is what a contract administrator needs at close-out and through the DLP.
