Ventilation & condensation
Wet windows, a steamy bathroom or mould that returns after cleaning? Get help with ventilation and condensation, including extractor fan installation and shower dome supply and installation.
For homeowners, landlords and property managers in Taranaki.
Recognise the problem
When moisture keeps collecting indoors
Tell us which rooms are affected and when the problem appears. The pattern helps establish whether ventilation work, treatment or further investigation is the right starting point.
A bathroom that stays steamy
The mirror, ceiling and walls remain wet after showers. The room may have a fan already, but moisture is still affecting the finishes.
Mould returns after cleaning
Repeated surface treatment has not resolved the problem. Airflow, cold surfaces or a leak may need attention alongside the mould itself.
The work
Ventilation work matched to the room
Healthy & Dry can help with the practical moisture problems below. The solution and any installation work are agreed after reviewing the property.
- Review of the affected rooms, visible condensation and how moisture builds up.
- Practical ventilation and airflow improvements within the agreed scope.
- Shower dome supply and installation where the enclosure is suitable.
- Extractor fan installation where it is the right solution, with electrical connection and testing arranged through a certified electrician.
- Mould treatment of agreed affected surfaces alongside ventilation work.
- Related repairs and repainting where moisture has damaged finishes.
We first check whether an extractor fan is the right solution and identify a suitable location with a power point nearby. Healthy & Dry installs the fan and arranges a certified electrician to connect and test it before handover. The location and electrical requirements are confirmed before work starts.
Shower domes
Shower dome supply and installation
A shower dome may be an option for containing steam within a suitable shower enclosure. Healthy & Dry supplies and installs shower domes, with the fit and installation scope confirmed before ordering.
Send a clear photo of the whole shower, the top of the enclosure and its surroundings. If you already have dimensions or a product in mind, include those too. Final measurements and suitability need to be checked before a product is selected.
What to consider
- Shower shape, dimensions and the top edge of the enclosure.
- Ceiling clearance, door movement and access for fitting.
- The condition of the shower lining and enclosure.
- Existing extraction and any other moisture problems in the room.
Treat a dome as a separate improvement. It does not establish that a rental property's ventilation meets the healthy homes standards; required ventilation must still be considered.
How it works
From the first enquiry to agreed work
Describe the pattern
Tell us which windows or rooms get wet, when it happens and what ventilation is already in place. Add photos of the room and shower if relevant.
Choose the starting point
Healthy & Dry reviews the work enquiry. An unclear moisture source or a need for written findings may require a separate Detections assessment.
Confirm the work
Agree the ventilation or shower dome work, product suitability, installation location and price. For an extractor fan, we identify a suitable location with a nearby power point and confirm the electrical requirements.
Complete and review
Healthy & Dry carries out the agreed installation. For extractor fans, we arrange a certified electrician to connect and test the fan before handover. We explain the relevant operating or care instructions.
Before we start
Useful steps before the visit
- Photograph condensation and affected finishes before wiping them dry.
- Note whether the problem follows showers, cooking, overnight conditions or rainfall.
- Describe the existing fan, opening windows and any ventilation equipment.
- Keep using the extractor after showering while moisture clears, following its operating instructions. A run-on timer or humidity control can be discussed with the electrician.
- For rental properties, discuss the proposed work and access with the landlord or property manager.
Do not open electrical fittings, climb into unsafe roof spaces or block ventilation openings. If water may be affecting electrics, keep clear and seek help from the appropriate qualified trade.
Scope, cost and timing
Agree the solution before buying equipment
The price depends on the room, product, access and the extent of treatment or repair work. A shower dome needs its own fit and supply check; there is no single installed price for every enclosure.
Tell us if the property is occupied and whether the bathroom is the only one available. Work dates, product availability and any separate trade visits are confirmed before booking.
Ventilation work cannot repair an active leak or automatically resolve every cause of dampness. If those issues emerge, agree the investigation or repairs before extending the work.
Healthy & Dry enquiry
Which rooms are getting wet?
Start with what you notice. Healthy & Dry will discuss the practical work and whether more information or a visit is needed.
Useful details to include
- Town, affected rooms and when condensation appears
- Photos of the windows, ceiling, existing fan or shower
- Whether you want shower dome supply and installation
- Any leaks, previous treatment or Healthy Homes report
This is a work enquiry. The installation quote confirms the fan work, electrician connection and testing, and any additional repairs. A separate site assessment is agreed if needed.
Your questions
Frequently asked questions
Have a question about ventilation, condensation or shower domes? Read the answers below, or use the enquiry form to discuss your property.
Why are the windows wet even when the room feels warm?
Moist air can condense on colder glass and frames. The pattern matters: showers, cooking, overnight moisture and cold surfaces can all contribute. Describe the affected rooms and when it happens so ventilation work can be considered alongside other possible causes.
The bathroom already has a fan. Why is it still steamy?
The presence of a fan does not establish how well it removes moist air. Its operation, the route outdoors and the room's ventilation need consideration. Healthy & Dry first checks whether fan installation is the right solution. We identify a suitable location near a power point, install the fan and arrange a certified electrician to connect and test it before handover.
Do you supply and install shower domes?
Yes. Healthy & Dry offers shower dome supply and installation. The enclosure, dimensions, clearances and condition are checked before selecting the product and confirming the work. Include photographs of the whole shower and its top edge with your enquiry.
Will a shower dome fit any shower?
Suitability needs to be checked for the particular enclosure. Shape, dimensions, ceiling clearance and the top edge all matter. Photographs help with the first discussion, but do not replace checking the fit before a product is ordered.
Does a shower dome replace the required rental ventilation?
Do not rely on a dome as proof of compliance. Tenancy Services sets requirements for opening windows and outdoor extraction, with specific alternatives and exemptions. A property's ventilation needs to be checked against those requirements separately from the dome installation.
Can you treat the mould and repaint as well?
Related mould treatment, repairs and repainting can be discussed through Healthy & Dry. The affected surfaces and moisture contributor need to be considered first. These tasks are included only when they form part of the confirmed scope and price.
Do I need an assessment before ventilation work?
Not every enquiry needs the same starting point. If the cause is unclear, dampness may be coming from a leak or you need written findings, ask about an assessment through Detections. That assessment is separate from Healthy & Dry's treatment and installation work.
What determines the cost?
The room, product, fit, access and any associated repairs or trade work affect the price. Send the property location, photos and your priorities first. The work, price and timing are confirmed before anything is booked or ordered.
