In this climate the stain on the wall is rarely the whole problem, and four years after the floods, a lot of mould is still inside cavities that look clean. Tell us what you can see and smell. Your enquiry may be referred to one independent local remediation contractor, who inspects, quotes and contracts with you directly.
Northern Rivers Mould Removal is an independent referral service and does not perform or contract for the advertised work. Your enquiry may be referred to an independent contractor. Where licensing is required, the contractor's identity and licence details will be provided before you accept a quotation or enter a contract.
Three questions, three honest paths. Post-flood answers land differently here than anywhere else in the state, so start with the water, not the stain.
A small patch (under about one square metre) on a non-porous surface can be cleaned yourself once the moisture source is fixed: NSW Health’s household mould guidance covers doing it safely with gloves, a mask and good ventilation. No contractor needed, and this site says so.
Read the DIY vs professional guideLarger areas, porous materials or any flood-affected home point to professional remediation: finding what drove the moisture, then a written scope from a contractor. Flood inundation especially; contaminated floodwater colonises materials that surface cleaning cannot fix.
Get my free quoteWhen the mould is concealed (a smell, a history, nothing to see) the honest first step is finding out what is actually there: moisture mapping, air sampling, a written report. Test before anyone quotes remediation, so the scope answers evidence rather than guesswork.
Ask about testing firstAll three paths are real outcomes, and sometimes the right answer is the one that earns nobody anything. Answer the three questions and the matching path is highlighted; without JavaScript, all three read in full above. Northern Rivers Mould Removal refers remediation enquiries only and does not perform any of this work itself.
Northern Rivers NSW is one of Australia’s most beautiful regions, and one of its most demanding when it comes to indoor mould. Subtropical humidity, salt-laden coastal air, the aftermath of the catastrophic 2022 Lismore floods, and a housing stock full of older timber homes create conditions where mould doesn’t just appear, it thrives.
A musty smell in your bathroom. A dark patch creeping across the ceiling. A persistent cough that clears up when you leave the house. If any of this sounds familiar, you’re not alone. Mould affects thousands of Northern Rivers homes every year, and in our humid climate, surface cleaning rarely solves the underlying problem.
Northern Rivers Mould Removal is a referral service. We are not a contractor and we do not carry out mould work ourselves. We take your enquiry, and it may be referred to an independent local mould contractor who inspects, quotes and invoices you directly, anywhere from Byron Bay and Lennox Head on the coast, through Ballina and Lismore, all the way inland to Bangalow, Mullumbimby, Murwillumbah, and Casino.
Send the quote form with your suburb and what you can see and smell.
An independent local contractor inspects, confirms scope, and quotes in writing.
Carried out by the contractor you are referred to, who deals with you directly.
You always know who is who: we refer, the contractor quotes and contracts with you directly.
The scope decides the price. These pages set out what moves it on a job like yours, so you can read a quote and know whether it stacks up.
We refer, the contractor quotes and contracts with you directly. The operator who reviews your enquiry is named on every page of this site.
Northern Rivers Mould Removal is a referral service, not a contractor. An independent local contractor quotes you, invoices you and does the work. Your contract is with them, not with us, and you pay us nothing.
Any price on this site is a market guide, not our price. Only a contractor who has inspected the site can quote you properly, and that quote is free and carries no obligation.
Before anyone prices anything, work through what drove the moisture, what it reached and how the building will actually dry.
Flood, storm, roof or plumbing leak, or long-term humidity
Timber, plasterboard, insulation, furnishings and concealed cavities
Airflow, dehumidification, subfloor or roof-space moisture
Every job quoted and carried out by an independent local contractor, not by us.

This service covers the Northern Rivers, from Lismore and Casino through to Ballina, Byron Bay, the Tweed and the Richmond Valley. Here, high rainfall, flood recovery and subtropical humidity keep building cavities damp long after the visible surfaces look dry. Timber, plasterboard, insulation, subfloors and roof spaces can all hold moisture you cannot see, so the water history and the way the property dries matter more than the stain on the wall.
This is the actual pipeline behind the form, not a service promise: no response time is guaranteed while the referral network is being established. You can withdraw your enquiry at any time via quotes@northernriversmould.com.au.
Tell us what you can see and smell, which rooms, and any flood or leak history. Your enquiry may be referred to an independent local contractor.
