Bayswater North homes often combine older brick veneer builds with newer renovations—both can trap moisture in roof spaces, subfloors and bathrooms if ventilation and drainage aren’t right.

Our comprehensive service includes everything you need to make an informed decision about your property.
We check around showers, vanities, toilets, splash zones and skirting lines for visible mould, bubbling paint, swollen trims and musty odours. These wet areas are the most common starting point for mould in Bayswater North homes, particularly where older waterproofing or grout breakdown lets moisture migrate into wall cavities.
We take moisture readings in the areas that show symptoms (or sit near plumbing and wet areas), including external corners, behind toilets, and adjacent rooms. This helps distinguish surface condensation from a leak or rising damp pattern, so repairs target the cause rather than repeated cleaning.
We inspect accessible roof spaces for signs of past or active leaks, damp insulation, mould growth on timbers, and poor roof ventilation. Minor roof leaks can present as mould long before obvious ceiling damage, especially after seasonal wet weather.
For homes with subfloor access, we assess ventilation, ground moisture, plumbing leaks and mould-prone timbers. Subfloor dampness can push musty air up into the home and drive mould at skirting level, particularly in rooms with limited airflow.
We assess exhaust fan performance, air pathways, window condensation patterns and furniture placement issues that restrict airflow. Condensation-driven mould is common in bedrooms and built-in robe areas, and often needs a ventilation strategy rather than cosmetic patching.
Your report documents observed mould presence, moisture indicators and the most likely contributing factors (leaks, ventilation, drainage or condensation). We outline practical next actions such as trade investigations to request, areas to open up, and risk prioritisation for buyers and property owners.

It can be either, and the pattern matters. In Bayswater North we often see condensation mould in bedrooms, corners and behind wardrobes where airflow is poor, while leaks tend to show around showers, laundries, roofs and plumbing runs. A mould presence inspection combines visual checks with moisture readings to help separate a ventilation issue from an active moisture source.
We start with accessible areas and non-invasive moisture testing to identify likely wet zones. If readings and symptoms suggest moisture is trapped inside a cavity, we document the risk and recommend the most appropriate next step, such as a targeted invasive inspection by the right trade. This approach avoids unnecessary damage while still giving you a clear plan.
We prioritise wet areas (bathrooms, laundries, ensuites), then move to roof space and any rooms showing odour, staining or condensation. We also check common problem spots like external corners, behind large furniture, and built-in robes. The goal is to map where mould is present and why moisture is persisting in those locations.
Not always. Renovations can improve waterproofing and ventilation, but they can also introduce new issues—like tightly sealed windows reducing airflow, or cosmetic upgrades covering early moisture damage. In Bayswater North we regularly find mould in renovated bathrooms where exhaust is inadequate or where moisture has tracked behind new wall linings. Inspection helps confirm what’s actually happening behind the finish.
If possible, provide access to wet areas, the manhole for the roof space, and any subfloor entry. Don’t bleach or repaint mould-affected areas immediately beforehand, as it can hide indicators we need to document. If you’ve noticed patterns—worse after rain, after showers, or during cold mornings—tell us, as that timing helps pinpoint whether the driver is leaks or condensation.
