Homeowner Problems
Identify the problem affecting your home, understand potential risks, and discover what to do next.
Every home can develop problems over time, from water ingress and structural concerns to plumbing faults, electrical hazards, deteriorating building materials and heating or ventilation issues. Understanding the warning signs and possible causes is the first step towards finding an appropriate solution. Explore the problem categories below to identify your situation, access available New Zealand-specific guidance and understand when professional assistance may be required. We’ll continue expanding these resources as new guides become available.
Safety First — When to Get Urgent Help
Some property problems can present immediate safety risks. Fire, suspected gas leaks, exposed or wet electrical wiring, rapidly rising floodwater, significant structural movement or signs of possible collapse all require urgent attention. Keep people away from affected areas and leave the building if necessary. If anyone is in immediate danger, call 111.
Do not touch exposed electrical wiring or water-damaged electrical equipment, operate electrical switches where a gas leak is suspected, climb onto an unsafe roof or enter an area showing signs of structural instability. Avoid contact with sewage or potentially contaminated floodwater. Keep clear of dangerous areas and contact an appropriately qualified professional rather than attempting hazardous repairs yourself.
If there is no immediate danger, document the problem with photographs taken from a safe location and arrange an assessment by an appropriately qualified tradesperson or specialist. Where significant property damage has occurred, contact your insurer promptly and keep records of the damage, professional advice and any emergency work undertaken.
What Problem Is Affecting Your Home?
Problems affecting New Zealand homes can involve water ingress, structural movement, plumbing, electrical systems, building materials or indoor comfort. Because different faults can produce similar symptoms, identifying the right problem category is an important first step. Explore the six categories below to understand potential causes, recognise warning signs and find appropriate guidance. Our Water Ingress & Dampness guides are already available, with further problem resources being developed progressively.
Water Ingress & Dampness
Water leaks, damp walls, ceiling stains, mould, condensation and drainage problems can have different causes. Explore eight detailed guides covering warning signs, possible causes, repair options and recommended next steps.
Structural & Foundation Problems
Cracks in walls, uneven floors, sticking doors and signs of foundation movement can indicate structural concerns. Understand the warning signs, potential risks and when assessment by a structural engineer or other specialist may be necessary. (Detailed guides coming soon)
Plumbing & Water System Problems
Leaking pipes, blocked drains, low water pressure and hot-water system faults can disrupt everyday life and cause costly damage. Understand common warning signs, possible causes and when professional plumbing assistance may be required. (Detailed guides coming soon)
Electrical & Safety Problems
Flickering lights, frequently tripping circuits, overheating power points and damaged wiring may indicate electrical hazards. Recognising the warning signs and knowing when to stop using affected equipment and call a licensed electrician can help protect your home. (Detailed guides coming soon)
Building Defects & Materials Problems
Rotting timber, deteriorating cladding, corrosion, defective workmanship and potentially hazardous materials can affect a home’s condition, safety and value. Learn to recognise warning signs, understand possible risks and identify when specialist assessment may be needed. (Detailed guides coming soon)
Heating, Ventilation & Comfort Problems
Cold rooms, uneven heating, poor ventilation, inadequate insulation and uncomfortable indoor temperatures can affect a home’s comfort and energy efficiency.

Which Professional Might You Need?
- Water Ingress & Dampness: An appropriately qualified roofer, licensed plumber or drainlayer can investigate roof, pipe and drainage leaks. Complex moisture problems involving cladding, windows or concealed building defects may require an experienced building surveyor or weathertightness specialist.
- Structural & Foundation Problems: A structural engineer can investigate significant cracking, movement, damaged structural elements and foundation concerns. Where ground instability, settlement or slope movement is suspected, a geotechnical engineer may also be required to assess underlying soil and ground conditions.
- Plumbing & Water Systems: An appropriately licensed plumber can investigate leaking pipes, low water pressure, faulty plumbing fixtures and hot-water system problems. Blocked or damaged wastewater drains may require an authorised drainlayer, while complex water supply or drainage issues may need specialist investigation.
- Electrical & Safety Problems: A licensed electrician can investigate faulty wiring, frequently tripping circuits, overheating electrical fittings and other electrical safety concerns. More complex installations or suspected compliance issues may require an authorised electrical inspector or specialist electrical contractor.
- Building Defects & Materials: An experienced building surveyor or suitably qualified builder can investigate deterioration, defective workmanship, cladding concerns and damaged building materials. Suspected asbestos or other hazardous materials may require specialist assessment, testing and appropriately licensed removal contractors.
- Heating, Ventilation & Comfort: A qualified heating, ventilation or heat-pump specialist can assess inadequate heating, poor airflow and inefficient systems. Insulation installers, experienced building professionals or indoor environmental specialists may also be needed to investigate heat loss, ventilation deficiencies and indoor air quality concerns.
