Building Defects

Building Defects on the Northern Beaches

Cracks that keep growing, doors that won’t close, water where it shouldn’t be — building defects are your home telling you something’s wrong. We identify what’s actually causing it, document it, and rectify it properly, for homes across the Northern Beaches and North Shore.

The Signs

The defects we’re called in to identify and fix.

Some defects are cosmetic; others are the visible edge of a structural or water problem. The trick is telling which is which — so you fix the cause, not just the symptom.

Cracking in walls & cornices

From movement, footings or poor construction.

Doors & windows that stick

Frames racking as the structure moves.

Sagging or bouncing floors

Deflection in joists, bearers or slabs.

Water ingress & damp

Failed flashing, membranes or drainage.

Movement & subsidence

Footings or ground moving under the home.

Poor workmanship from a past build/reno

Defects handed over and never put right.

A defect assessment tells you what’s cosmetic, what’s serious, and what it takes to fix.

What We Do

Identify the cause, report it clearly, rectify it right.

We diagnose what’s really going on, give you a clear written assessment, and carry out the rectification — one accountable team from diagnosis to fix.

Assess, report, rectify, verify.

Defects need the cause pinned down before anyone starts fixing — so you spend on the right repair, once.

Site assessment

We inspect the home and the symptoms you’re seeing.

Diagnosis & report

Establish the cause and provide a clear written assessment with an itemised quote.

Rectification

Carry out the structural, water or finish repairs required.

We’d been told three different things about the cracking in our home. Beaches Group assessed it properly, gave us a clear written report on what was structural and what wasn’t, and rectified it — finally an honest answer and a proper fix.

Common Questions

Building defects, answered.

What counts as a building defect?

Anything that shouldn’t be happening in your home — cracking, movement, sticking doors, sagging floors, water ingress, or poor workmanship from a past build or renovation. Some are cosmetic; some point to a structural or water problem. An assessment tells you which.

Is my crack serious or just cosmetic?

Some cracks are harmless settlement; others track structural movement. Width, location, direction and whether they’re still growing all matter. We assess it properly rather than guess — and we’ll tell you honestly if it doesn’t need major work.

Do you provide a written defect report?

Yes. We give you a clear written assessment of what’s wrong, the likely cause and what rectification involves — useful for your own records or an insurance claim.

Can you fix defects left by a previous builder?

Yes — that’s a common reason people call us. We diagnose what was done wrong and rectify it properly, as one accountable team.

How much does defect rectification cost?

It depends entirely on the defect and its cause, so we price against your home after a site assessment and give you an itemised scope before any work starts.

Where do you work?

The Northern Beaches and Sydney’s North Shore — for residential homes.
