Contained mould cleaning
Affected walls, ceilings and sealant cleaned behind sheeting, with HEPA vacuums and a cleaner suited to the surface, never by dry brushing.
Per roomfrom $240
Mould cleaned out, and the cause put right
Dryhaven inspects damp and mould in homes, rented flats and offices, finds out why it grew, removes it under containment and fixes the leak or the condensation behind it. Every job comes with a written report of readings, photos and the work done.

Why the mould grew
Mould only grows where there is moisture. Cleaning it without finding that moisture buys a few months at most, so every inspection starts by looking for the water.
| What you see | The usual source of moisture | What we put right as well |
|---|---|---|
| Black spots in the top corners of a bedroom, worse each winter | Condensation, as warm air from breathing, cooking and drying laundry settles on a cold wall | Ventilation improved, and advice on heating and airing that fits how you live |
| A dark patch spreading under a window | Water running off the glass, or rain finding a gap around the frame | Frame seals renewed and the trickle vents checked |
| Mould on the wall behind a wardrobe or sofa | A cold outside wall where no air moves | Furniture spaced off the wall, and the cold spot insulated where it can be |
| A musty smell in the bathroom or under the sink | A slow leak from a pipe, a trap or a shower seal | The leak repaired and the wet boards dried and measured |
| Mould on a ceiling just under the roof | A roof leak, a blocked gutter or thin loft insulation | Roof or gutter repair arranged, insulation topped up |
| Mould low on ground floor walls with a tide mark | Damp coming through or up the wall from outside | Readings passed to a damp proofing specialist, as this needs separate work |
These are common patterns rather than a diagnosis. The readings taken in your home decide what is really going on.
An inspection that finds the water first
An inspector spends about an hour with you, carrying a pin meter, a thermal imaging camera and a small humidity logger. Walls, ceilings, floors and window frames are read room by room, and the outside of the building is checked for gutters, pipes and roof edges near the damp.
We also ask how the rooms are used, such as where laundry dries and whether the bathroom fan runs, because the answers change the plan. Samples go to a lab only when they would change what we do, for example when hidden mould is suspected inside a wall.
- Readings marked on a sketch of each room
- Humidity logged for a week when condensation is likely
- Outside walls, gutters and pipes checked
- Report, photos and a fixed price within three days
Removal and repairs we carry out
Guide prices for a typical home. Your fixed price is in the report, and work starts only once you have agreed to it.
Removing damaged materials
Plasterboard, carpet, underlay or skirting that mould has grown into is cut out, bagged inside the room and carried out sealed.
Typical wall sectionfrom $650
Ventilation and extraction
Kitchen and bathroom extractor fans, humidity controlled fans and trickle vents fitted or upgraded to carry damp air outside.
Per fan, fittedfrom $380
Leak and source repairs
Dripping pipes, failed shower seals, blocked gutters and gaps around window frames repaired by our own tradespeople.
Small repairfrom $180
Drying out after a leak
Dehumidifiers and air movers placed and checked, with readings taken until the structure is dry enough to repair.
Per weekfrom $320
Finishing and protection
Mould resistant paint and new sealant once the cause is fixed, so the room looks right and stays easy to wipe down.
Per roomfrom $160
Prices include containment and disposal. Lab samples, when the inspection calls for them, are added at cost and shown as a separate line.
From the first call to a room that stays dry
Most homes are finished within a week of saying yes. Larger drying jobs take longer, and the report tells you how long before you decide.
Inspection
About an hour on site, reading every affected room and looking at the outside of the building.
Report and price
Readings, photos, the likely causes and a fixed price arrive within three working days.
Contain and remove
The room is sealed, the air filtered, and the mould cleaned off or cut out and bagged.
Fix the cause
Leaks repaired, ventilation improved or insulation added, depending on what the readings showed.
Recheck
Six months later we come back with the meter to make sure the room has stayed dry.
Living at home while we work
Most households stay at home throughout. These are the precautions we take in every room we treat.
- Rooms sealed with sheeting and taped doors
- Air filtered through HEPA units
- No dry brushing or sanding of mould
- Waste bagged before it leaves the room
- Children and pets kept out of the work area
- Tools and floors cleaned before we go
Damp and mould can be a worry for anyone with asthma, allergies or a weakened immune system. We are not doctors and cannot give health advice, so if you are concerned about your own health or a family member's, please speak to your doctor. If someone is struggling to breathe, call your local emergency number.

From householders and landlords (example reviews)
The inspector found that the bedroom mould came from a cold corner and a bathroom fan that had never been wired to run. Cleaning took a morning, the new fan went in the same day, and the wall has stayed clean all winter.
For a landlord, the written report is what counts. It showed our tenant and us exactly where the leak was and what was fixed, with readings from before and after.
They told us plainly that the patch under the window was condensation and did not need the costly work another company had suggested. New trickle vents, a careful clean, and it has not come back.
Questions about damp and mould
Will bleach get rid of it?
Bleach can whiten mould on a hard surface, but it rarely reaches mould that has grown into plaster, wood or sealant, and it does nothing about the moisture. For a small patch on tiles, a household mould cleaner and better airing may be enough, and the report will say so.
Is the mould affecting our health?
We cannot answer that, because it is a medical question. Some people do react to mould and damp, so please talk to your doctor about any symptoms. If anyone is fighting for breath, ring your local emergency number at once.
Will it come back?
It can, if the moisture that fed it is still there. That is why we fix the cause as well as the mould and return after six months with the meter. If mould has returned on a wall we treated, we look at it again at no charge.
Do we need to move out?
Rarely. Most work takes place in one or two sealed rooms while the rest of the home is used as normal. The report tells you if a room should stay empty for a day or two.
Who pays in a rented home?
That turns on the tenancy agreement and on local housing rules, which differ between countries and even regions. Tenants and landlords both hire us, and the report helps both sides see what caused the mould and what was done about it.
How is the work paid for?
Inspections are paid on the day of the visit. For treatments we take a deposit when you agree the price and send the final invoice once the room is done; you pay our office directly, by arrangement.
