Got a remedial quote that made your stomach drop? Watch this before the committee sees it.

The number is only frightening while it's one line. Scaffold, access, staging, investigation and the builder's contingency are all bundled in there — and in most strata quotes, the work itself is the smaller share. In two minutes, our founder shows you the three places the money hides.

Why it matters now

The defect you can see is the cheapest part of the problem.

Building defects compound. A crack lets water in, water corrodes the steel, the steel expands and cracks more concrete — and every month the scope and the cost grow. The cheapest time to remediate properly was when the engineer first flagged it. The second cheapest is now, before the next repair gets bolted onto the bill.

Atomic vs a typical contractor

Why our remediation doesn't fail twice.

The cheap quote patches what's visible and walks away. Here's what that difference costs your building.

Manly low-rise strata balcony waterproofing project — Atomic ProjectsROOFTOP PVC Waterproofing

Mid-Rise Strata — Warwick Farm

One residential tower with active roof leaks. Rooftop waterproofing had failed and water was getting into the units below every time it rained. We stripped the roof back to substrate, found the root-cause of failure at service penetrations and installed a new sheet membrane system with proper falls and drainage.

"They set up their team and completed the works all at once, not a single day of lost time was caused."

Miranda high-rise balcony waterproofing project — Atomic ProjectsCONCRETE & STRUCTURAL REPAIRS

Mid-rise strata — Randwick

Concrete slabs with severe steel corrosion and spalling. Steel corrosion and spalling had compromised the balcony slab — water was leaking through the voids with rebar corroding behind the surface. All drummy concrete was removed to sound substrate, reinforcement was treated with zinc, high-strength mortar re-applied and the slab was restored for the long term.

"They worked level by level so nobody had to move out. Spalling across three floors fixed in five months, with no complaints."

Darling Point rooftop waterproofing project — Atomic ProjectsBRICK FACADE REMEDIATION

Heritage Warehouse — Alexandria

Bricks were detaching from a heritage facade directly above the street. Full restoration program — repointing, brick replacement, crack stitching with stainless steel helicals, and corbel rebuilds. Facade stabilised in two months with zero compromise to the building's original character.

"Bricks were literally falling onto the footpath. They made it safe within days and then restored the whole facade."

What it costs

Straight answers on price.

This industry hides its numbers. We don't. Here's a realistic range before you speak to anyone.

$100K – $2M+
Typical strata remediation, depending on building size, defect scope and access. Example: three integrated scopes at St Leonards ≈ $1M+; 18 staged balconies at Miranda ≈ $980K.

Fixed price, before we start.

After a site assessment you get a line-by-line, engineer-checkable scope your committee can approve at the AGM — fixed price, fixed timeline, no mid-job surprises.

We only take strata & commercial remedial projects from $100K.

Risk reversal

Warrantied in writing. Verify everything.

Most remediation fails because the last contractor patched instead of fixing — and walked away with no warranty. We don't.

Written 10-year warranty — transferableIt follows the building, not the committee that signed it.

Engineer-directed & documentedA QA paper trail your committee and engineer can audit at any stage.

Manufacturer-backed systemsWe install to manufacturer specification and hand you the certification paperwork — so your warranty isn't only as good as your builder.

Is this you?

We're a fit for some buildings, not all.

This is for you if…

  • You manage a strata or commercial building in Sydney
  • You have defects — facade, concrete, waterproofing or structural
  • The project is $100K or more
  • Your committee wants documentation and a real warranty
  • Residents need to stay in place during works

Probably not us if…

  • It's a single-dwelling home or a small one-off patch
  • You want the cheapest re-coat, not a lasting fix
  • The job is under $100K
  • You need work outside Sydney

Atomic Projects were able to complete this project within the span of one week. Supervisor Ogn and team were professional and kept me updated and explained the process through out.

The TBES team have used Atomic Projects for multiple sites to assist with further investigation works. We have recently also completed a project in Miranda involving structural repairs.

Who you're dealing with

You'll deal with the builder, not a call centre.

I started Atomic Projects because I was tired of watching committees pay twice — once for the patch, then again for the real repair. Every project we take, I'm accountable for. Send me your engineer's report and I'll tell you straight what the last team missed.

Common questions

What your committee will want to know.

We've had three different builders look at this. How do we know you'll actually fix it?+
We only do remedial work — it's not a side job for us. We start with a proper investigation to find the actual cause, not just what's visible. That's usually exactly why the previous attempts failed.
What if the scope turns out to be bigger than quoted?+
We investigate before we price, so the scope is set before we start — not discovered halfway through. If the assessment reveals something hidden, you'll see it in the quote, not in a variation later.
Your quote is higher than the others. Why?+
Because it's a different scope. The cheap quote patches what's visible and walks away; ours fixes the cause and is warrantied in writing. Pay once for the real repair, or pay twice — patch now, then the proper job when it fails. We'll show you exactly what the cheaper quote leaves out.
Can you work while residents are in the building?+
Yes. We stage the works so only a few units are affected at any one time and people keep their homes and parking. Occupied buildings are our normal — not the exception.
How long does a remedial project take?+
It depends on scope, but you get a fixed timeline before we start — not an open-ended one. A targeted repair can be weeks; a full multi-trade program runs months. You'll have the dates at quote stage so your committee can plan around them.

Your building deserves better.
