Common questions

Your Questions

Can't see what you need? Call John on 0418 469 454.

Three things. Structural remediation and remedial consulting — concrete spalling and cancer repairs, underpinning, structural steel, facade upgrades and waterproofing, usually in buildings people are still living in. Architectural custom homes and duplexes, built from the drawing set detail for detail. And high-end renovations, extensions and granny flats.

Plenty of jobs span two of those. When they do it is still one contract, one programme and one person who answers the phone.

Yes, and every number is published so you can check it against the register rather than take our word for it. Builders Licence 387732C, Supervisor Certificate 32194S, Building Practitioner BUP0002540 with nominee BUP0002093.

We are certified to ISO 9001, ISO 14001 and ISO 45001 — quality, environment and safety, independently audited rather than self-declared. We carry public liability, workers compensation and contract works insurance, and every project is backed by our ten-year workmanship guarantee.

Constantly — it is most of what we do. On remedial work we come in alongside your structural engineer from diagnosis through to certified sign-off, so the report, the plans, the approvals and the work itself stay with one accountable team instead of being handed between three.

For a strata committee that means scheduled access, hold points evidenced as they are reached, and residents who are told what is happening before it happens. We are equally comfortable being the contractor named in a scope of works somebody else wrote.

Across Sydney, concentrated in four areas: the Inner West (Drummoyne, Balmain, Burwood, Newtown, Marrickville), the Eastern Suburbs (Bondi, Coogee, Randwick, Vaucluse, Double Bay), South Sydney (Rockdale, Hurstville, Cronulla, Miranda) and the North Shore and Northern Beaches (Mosman, Manly, Freshwater, Chatswood, North Sydney).

We are based in Russell Lea and work across the metropolitan area, so if your building sits outside those suburbs it is worth asking.

Two ways. Call John on 0418 469 454 or Jarryd on 0414 658 052 — you will reach one of them directly, not a call centre. Or send the enquiry form on any page: it asks what kind of project you have, then only the questions that actually apply to it.

Either way the next step is the same. We arrange a time to look at the building, and you get a written quote off the back of that rather than a number over the phone. There is no charge for the initial quote.

Earlier than most people do. If a building is showing cracking, spalling or water coming in, the cheapest version of the job is the one diagnosed before the damage spreads — so it is worth calling at the point you are deciding whether you need a report, not after you have three quotes priced against a scope that may not be the right one.

On a new home or a renovation, talk to us while the drawings are still moving. Buildability and budget are far easier to influence before an application is lodged than after it comes back approved.

Yes. We can take a project from concept and approvals through to handover, working alongside your architect and engineer or introducing you to the ones we work with.

That gives you one contract, one programme and one party answerable for both the drawings and the building — which is the point of it, because it closes the gap where design and construction can each blame the other. If you already have a completed set of documents, we are happy to price against those instead.
