Remedial building works we deliver
Balcony and podium waterproofing
Leaking balconies, planter boxes and podiums are the most common strata defect. We strip back to the substrate, rectify falls and drainage, install compliant membranes and reinstate finishes, so the leak doesn’t return after the next wet season.
Concrete cancer and spalling repair.
Corroded reinforcement cracks and pushes concrete off slab edges, balconies and columns. We break out affected concrete, treat or replace the steel, and reinstate with repair mortars specified by the engineer.
Structural remediation
Working with your structural engineer on slabs, beams, retaining walls and load paths, from investigation through to certified repair.
Facade repairs and recladding
Water ingress, structural cracking, failed fire separations and defects found in a building report. We work from your expert report or engineer’s scope and close each item out with evidence.
Remedial work on Class 2 buildings and the DBP Act
Remedial work on apartment buildings in NSW falls under the Design and Building Practitioners Act 2020. Regulated designs must be prepared and declared by a registered design practitioner, and the builder must be a registered building practitioner who declares the work complies before it’s completed. Shafbuild holds a NSW Class 2 Building Practitioner registration (BUP4254234), so your committee gets a builder who can lodge the required declarations.
How we work with owners corporations
We focus on delivering complex remedial and upgrade works with care, clarity, and full compliance. We understand the challenges that come with live environments, consultant led scopes, and committee-led approvals, and we bring the experience, structure, and licensing needed to deliver major projects properly.

What remedial work costs
Cost depends on the extent of the defect, which is only known once the surface is opened up, plus access (scaffolding or swing stage), the number of affected units and the engineering requirements. That’s why we price from a defined scope and flag provisional sums upfront, rather than give a headline number that grows on site.

Frequently Asked Questions
What does a remedial builder do?
A remedial builder repairs, restores, and upgrades existing buildings rather than constructing new ones. At Shafbuild, our remedial works cover facade remediation, concrete cancer and spalling repair, waterproofing, membrane replacement, fire compliance upgrades, structural rectification, and full building repaints. As a licensed remedial building company, we diagnose the root cause of building defects and deliver durable, compliant fixes that protect long-term asset value.
Are you strata remedial builders?
Yes. Strata is our core focus. As registered Class 2 strata remedial builders, we work directly with strata committees, building managers, owners corporations, and their consultants. We understand committee approval processes, capital works fund planning, live-site coordination, and the reporting standards strata schemes expect from their remedial builders.
Do you offer remedial builders in the Eastern Suburbs?
Yes. We're remedial builders based in the Eastern Suburbs and regularly deliver strata and remedial projects across Kensington, Randwick, Coogee, Bondi, Maroubra, Waverley, and surrounding areas. Being local means faster site attendance, easier committee meetings, and remedial builders who know the Eastern Suburbs building stock.
How do I find reliable remedial builders near me in Sydney?
Look for remedial builders with a current NSW Builders Licence, Class 2 Building Practitioner registration, and full insurance, then check their strata track record. Shafbuild is based in Kensington and works as remedial builders right across Sydney, so owners corporations searching "remedial builders near me" get a licensed, local team with genuine experience in live strata environments.
Do you provide remedial builders on the Northern Beaches?
Yes. We deliver facade, concrete, and waterproofing remedial works as remedial builders across the Northern Beaches, from Manly and Dee Why through to Mona Vale and Palm Beach. Coastal buildings face heavy weathering and concrete spalling, and our remedial builders are experienced with the salt-air conditions common to Northern Beaches strata schemes.
What areas of Sydney do your remedial builders cover?
Beyond the Eastern Suburbs and Northern Beaches, our remedial builders service the Inner West, Lower and Upper North Shore, CBD, and Greater Sydney. Wherever your scheme is located, Shafbuild delivers strata remedial building works with the same structure, compliance, and communication.
What is the difference between a remedial builder and a regular builder?
A regular builder mostly constructs new structures, while a remedial builder specialises in repairing and upgrading existing buildings, often occupied ones. Remedial building demands defect diagnosis, staged works around residents, and close coordination with engineers and building consultants. Choosing a dedicated remedial building company like Shafbuild means the team understands these complexities from day one.
What remedial building services does Shafbuild provide?
Our remedial building services include facade remediation, concrete spalling and concrete cancer repair, waterproofing and remedial membranes, balcony and planter box rectification, fire safety and compliance upgrades, structural repairs, expansion joint replacement, and building repaints. As a full-service remedial building company we can manage single defect repairs or complete capital works packages.
How much do remedial building works cost?
Cost depends on the scope, building size, access requirements, and defect severity, so every quote is tailored. Rather than the cheapest number, strata committees benefit from remedial builders who scope accurately, price transparently, and avoid variations. We provide clear, itemised quotes so your committee and consultants can make informed decisions.
Can you work from a consultant's or engineer's scope of works?
Absolutely. Many strata remedial projects are consultant-led, and our remedial builders are experienced in delivering to engineer and building-consultant specifications. We tender competitively, coordinate closely with your consultant during construction, and provide the documentation and defect tracking that consultant-led remedial works require.
Are you licensed and insured for strata remedial works?
Yes. Shafbuild holds a NSW Builders Licence, is a registered Class 2 Building Practitioner, and is a HIA member with full public liability and professional indemnity insurance. This licensing qualifies us for complex Class 2 strata remedial works and gives owners corporations confidence their remedial building company is fully accountable.
How do you minimise disruption to residents during remedial works?
Our remedial builders plan works in stages, maintain clear access, and communicate schedules ahead of time. We provide consistent, jargon-free updates to residents, committees, and building managers so everyone knows what's happening and when. Minimising disruption in occupied buildings is central to how our remedial builders operate.
What is concrete spalling and can your remedial builders repair it?
Concrete spalling (often called concrete cancer) occurs when steel reinforcement inside concrete rusts and expands, cracking and breaking away the surrounding concrete. Left untreated it worsens and threatens structural integrity. Our remedial builders repair concrete spalling by exposing and treating the reinforcement, reinstating the concrete, and protecting the area to prevent recurrence, a common request across Eastern Suburbs and Northern Beaches coastal buildings.
How long do strata remedial projects take?
Timeframes vary from a few weeks for targeted repairs to several months for major facade or capital works packages. During scoping, our remedial builders provide a realistic programme with staged milestones so your committee can plan and budget with certainty.
How do I get a quote from your remedial builders?
Book a discovery call and one of our remedial builders will discuss your scope, arrange a site inspection, and prepare a detailed quote. Whether you have a consultant's scope ready or are just starting to investigate defects, we'll guide you through the process with clarity and full accountability.
What is a Class 2 builder and why does it matter for strata works?
A Class 2 builder is licensed and registered under NSW's Design and Building Practitioners scheme to work on Class 2 buildings, multi-storey residential apartment blocks where people live above and below one another. Most strata remedial projects involve Class 2 buildings, so engaging a registered Class 2 builder is essential for compliance. Shafbuild is a registered Class 2 builder and remedial building company, qualified to deliver and declare compliant remedial works on Class 2 strata schemes across Sydney.
Why choose Shafbuild as your remedial building company?
We combine Class 2 licensing, strata specialisation, tech-enabled defect tracking, and genuine local presence across Sydney's Eastern Suburbs and Northern Beaches. We take on the right projects and deliver them properly, so committees, building managers, and residents get lasting results from remedial builders they can trust.
