What is remedial building?

Fixing a failing building is a different discipline to putting one up: you're working on an occupied structure, diagnosing why something failed, and repairing it without turning residents' lives upside down. Remedial building is all we do — not a side line to new builds, the whole business.

Most defects have a cause you can't see. A leak on level 3 can start two floors up. Spalling concrete is often a symptom, not the problem. So we start every job with a proper investigation — not a guess off a photo — and we work to an engineer's direction with the documentation your committee, certifier or insurer needs to sign off.

Repair vs remediation — the distinction that catches committees: a repair patches what's visible. Remediation diagnoses and fixes the system that failed — so the problem doesn't come back, and the paperwork stands behind the fix.
Know the symptoms

6 signs your building needs remedial work.

Most defects show up long before anything fails outright. If you can see any of these, something underneath needs diagnosing.

1
Water stains on ceilings or wallsThe clearest sign water is already inside the structure — tracking from a failed membrane, joint or flashing above.
2
Cracking in walls, slabs or renderPattern, width and movement tell the story — some cracking is cosmetic, some is structural. Diagnosis tells you which.
3
Drummy tiles or lifting finishesHollow-sounding tiles and bubbling finishes mean water or movement has debonded the layers beneath.
4
Efflorescence and salt stainingWhite deposits show water is moving through masonry or concrete it should be running off.
5
Corroding fixings or reinforcementRust staining from balustrades, lintels or slab edges is a water path — and a safety liability the owners corporation carries.
6
Spalling or flaking concreteConcrete breaking away means water has reached the steel — it's now structural, not cosmetic.

Why it matters now

The problem you can see is a fraction of the one you can't.

Building defects don't stay still. Left unactioned, a maintenance item becomes a structural one — and a committee liability.

01

Safety risks

Failed fixings, spalling concrete and loose facade elements above walkways are a public-safety risk the owners corporation owns — and a council order waiting to happen.

02

Escalating repair costs

Water past a failed system reaches the structure and the units below. Caught early it's a contained repair; caught late it's concrete repair, internal make-good and a much bigger bill.

03

Loss of asset value

Defects show up in strata reports and pre-purchase inspections — and follow the building until they're fixed properly, dragging on every sale in the block.

Our approach

Remediate the smarter way.

We don't patch symptoms — we investigate the cause, fix the system that failed, and document it so the fix stands up.

1

Diagnose the source

Our building investigation identifies whether the problem comes from waterproofing failure, structural movement, or poor detailing — before a price is quoted, so the scope matches the actual cause.

2

Match the repair to the system

Defects live in systems — waterproofing, structure, facade, fire. We match the repair method to the system that actually failed, often integrated with waterproofing remediation.

3

Integrate repairs with the whole building

A defect in one system usually touches its neighbours — facades, windows, internal finishes. We tie the rectification into adjacent systems for long-term performance, often as part of façade remediation.

4

Cut costs by avoiding rework

Quick fixes always fail. Our approach follows investigation-led rectification done once, properly — so you're not funding the same defect twice.

Mixed-use strata facade in St Leonards after ACP cladding and window replacement — Atomic ProjectsFacade remediation & cladding replacement

Mixed-use strata — St Leonards

Council-ordered compliance upgrade. Non-compliant ACP cladding replaced with a certified system, rooftop re-waterproofed, and all windows and doors renewed. Three scopes integrated into a single 8-month program to minimise disruption and duplication.

"They combined three major scopes into one program and dealt with council directly. We expected 12 months of chaos — it was done in eight."

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."

Manly low-rise strata balcony waterproofing project — Atomic ProjectsCONCRETE CANCER · MAGNESITE

Mid-rise strata — Killara

A root-cause investigation traced concrete cancer and cracking through the internal slabs to magnesite topping — so a full slab remediation was needed to restore the structure. We removed the drummy concrete, treated and replaced corroded steel, and reinstated with Sika repair mortar under the direction of a Class 2 Design Practitioner. Residents stayed in place the whole time.

"Residents stayed in place the entire time — the staged works kept the building safe and the disruption minimal."

On your schedule
Is this you?

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

We'd rather tell you upfront than waste your committee's time. Here's who we're built for — and who we're not.

This is for you if…

  • You manage or own a strata or commercial building with defects or failing systems across common property.
  • You have an engineer's report or a defect that needs proper diagnosis, not a quick patch.
  • The building is occupied and works need to be staged around residents.
  • You need DBP-compliant documentation your committee and insurer can rely on.
  • Your project is from around $50K and up.

Probably not us if…

  • You need a single crack cosmetically filled or a one-off touch-up in one unit.
  • You're after the cheapest patch to get through the next inspection, not a lasting fix.
  • It's a small domestic repair under a few thousand dollars — a local handyman is a better fit.
  • You need it done this week without an investigation — we diagnose before we price.
They stripped it back, found the failures three other contractors missed, and gave us a system we can finally trust — without a single owner having to move out.

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 and it's still not fixed. Why would you be different?
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 why previous attempts failed.
What if the scope turns out to be bigger than quoted?
We'd rather find that at assessment than mid-job. The investigation is designed to surface hidden damage before we price it, so the quote reflects the real scope. If something genuinely unforeseen appears, you'll see the evidence and a variation before any extra work happens.
How much does remedial work cost?
It depends entirely on the cause and scope, which is exactly why we investigate first. You'll get a fixed-price quote against a defined methodology — no open-ended day rates.
Will residents be able to stay during the works?
In almost every case, yes. We stage remedial works — a few balconies or one section at a time — so the building stays safe and people keep access to their homes.
Do we need an engineer, or can you just start?
For structural and most strata works, an engineer's direction protects you — and we work to it. If you don't have one, we can collect the investigation evidence they need and coordinate from there.
Do you handle council or compliance orders?
Yes. We've delivered council-ordered upgrades and combustible cladding works with the documentation and declarations those orders require.
How long does remedial work take?
Localised repairs run weeks; multi-trade programs run months. The investigation confirms scope and programme before works start — and you'll see a clear timeline in the proposal.
Are you registered for regulated work on our building?
Yes — Class 2 DBP registered, Licence 360636C, verifiable on the NSW Fair Trading register. On Class 2 buildings, structural, waterproofing and fire-safety work must be delivered under declared designs — that's the framework we work in every day.
What does a remedial builder actually do?+
Remedial builders repair existing buildings rather than construct new ones: waterproofing failures, concrete spalling, facade and render defects, structural repairs and cladding replacement. The discipline is different from new-build work because the scope is diagnostic, the buildings are occupied, and the work must integrate with existing structure. Atomic Projects works exclusively on remedial projects across Sydney strata and commercial buildings.
How do I choose a remedial building contractor in Sydney?+
Check five things before price: current Class 2 DBP registration on the NSW register, a verifiable builder licence, current insurance certificates, a real inspection and test plan with hold points, and comparable remedial projects they can evidence. Then make every tenderer price the same engineer's specification. A cheap quote against an undefined scope is where budgets blow out.
What size projects does a remedial builder take on?+
Atomic Projects prices remedial projects from around $100K, with typical packages between $200K and $2M+ covering waterproofing, concrete, facade and structural scopes, and has delivered more than $20M of remedial work over ten-plus years. Smaller isolated defects are usually better handled by a maintenance contractor; defined remedial packages are where a specialist contractor earns its keep.
Is remedial building work covered by warranty?+
Yes. Completed works carry a defects liability period, typically 12 months, during which the contractor returns to fix anything that emerges at no cost, plus the statutory warranties that apply to residential building work in NSW. Inspection and test records from the project are handed over at completion, giving the owners corporation evidence behind every covered-up stage.
What is the difference between remedial work and building maintenance?+
Maintenance is routine and preventive: cleaning gutters, servicing plant, minor repairs that keep a building ticking. Remedial work rectifies failures: failed membranes, spalling concrete, cracked facades, defective cladding. It is engineer-directed, staged, and documented for compliance because on Class 2 buildings much of it is regulated building work. If the same problem keeps returning, it has crossed from maintenance into remediation.
