Comprehensive leak investigation
When it comes to dealing with leaks, it is important to pinpoint the problem areas to ensure that the issues are fully resolved.
If you are concerned that you may have a leak but aren't quite sure where, then Wellington Building Services can carry out both non-invasive and invasive leak investigations for you. These tests can determine the location and extent of the leak and allow an appropriate remediation plan to be developed. Non-invasive moisture testing leaves no visible damage to your property.
If you are dealing with a leaky home, any remediation work must be done to a high standard to prevent problems from recurring. From small-scale fixes to re-cladding a house or building, Wellington Building Services has years of experience dealing with building projects of all sizes. Our team can help you with all aspects of your project, including council consents if required.
Restore your building's integrity with our re-cladding services
When cladding systems fail, re-cladding is often the most durable solution. We remove affected materials, repair or replace any compromised framing, and install compliant, ventilated cladding systems that meet current code and look great. We align product choice with your maintenance goals and local conditions.
Our weathertightness remediation process is robust and compliant
A Clear, Staged Approach – From Investigation to Code Compliance Certificate
Addressing weathertightness problems may seem overwhelming. We offer guidance that extends past simple repairs and recladding, approaching each project strategically to achieve the best results and safeguard your asset with informed decisions. Our process is designed to give homeowners clarity, transparency, and confidence at every stage — with no surprises.
Step 1: Weathertightness Investigation
We begin by identifying whether your home has weathertightness issues and where water may be entering. What this may include:
- Non-invasive inspection (visual checks, moisture testing)
- Invasive investigation (localised opening of walls or cladding where required)
This step confirms the extent of the issue and whether remediation or recladding is necessary.
Step 2:
Report & Recommendations
You’ll receive a clear, easy-to-understand report outlining:
- Investigation findings
- Identified defects and risk areas
- Practical recommendations
- Whether recladding or targeted remediation is required
Step 3:
Design & Remediation Plans
If remediation or recladding is required:
- Detailed remediation and reclad plans are prepared
- Designs meet current Building Code requirements
- Junctions, drainage, and flashing details are clearly resolved
Optional at this Step
- For budgeting purposes, choose to have a cost estimate prepared on the provisional drawings
Step 6: Project Set Up
Once you accept our detailed, fixed quote, we commence planning for the construction and building programme, including:
- Finalising the building contract and insurance arrangements
- Developing the construction programme
- Booking a start date for works
- Scheduling resources for the project
Step 5: Project costing
Once drawings are consented, we provide a detailed, fixed quote for:
- Recladding works-based consent drawings
- Important Pricing Information
At this stage, we cannot necessarily provide a guide as to the cost of removal & replacement of rotten or damaged timber, as often these elements are concealed behind the cladding and can only be assessed once the cladding is removed.
Step 7: Demolition & Timber Assessment
After demolition:
-
Our contracted scope pauses at the completion of demolition pending the outcome of:Building consent compliance regime ( QA – get words for this from a WCC building consent approval letter – Townsend Rd)
A Registered Building Surveyor is engaged to:
- Inspect exposed framing
- Mark up timbers to be replaced
- Confirm which timbers are sound and which require replacement
Note: Depending on the extent of remediation, an amended building consent may be required. Once this inspection is complete & the amended consent plans are prepared, the full remediation scope can be accurately costed.
Why our process works
✔ Clear stages and responsibilities
✔ Transparent pricing at every step
✔ No assumptions about hidden damage
✔ Designed to protect homeowners from unexpected costs

Repair typically means fixing specific issues, such as replacing damaged cladding, repairing rot, or sealing leaks around windows and doors. Repairs target problem areas only and may be suitable if the damage is localised.
Reclad is where the exterior cladding is fully removed and replaced, and a more comprehensive approach is needed. To reclad, Plans and Consent will be needed, followed by a Building Surveyor. This option is usually recommended when damage or risk is widespread, or the original cladding system is failing across the home.
Choosing between recladding and repairs depends on the extent of moisture damage, risk of future leaks, and long-term durability. If you’re unsure, call us to assess the situation and get expert advice.
Yes. For reclads and significant remediation, a Building Surveyor leads the investigation and observation, and an Architect provides design and consent documentation. This pairing supports quality and compliance.
Often yes. We can prioritise high-risk areas first, then complete the remaining zones in phases to align with budget and weather windows.
It depends on the scope. Many projects are completed while homeowners remain in place with managed access and protection. We’ll confirm during planning.
Timeframes vary with house size and extent of repairs. After investigation and design, we’ll provide a clear programme with milestones and regular updates.
What are common signs my home isn’t weathertight?
Leaky buildings have become a big problem in New Zealand, often costing large amounts to fix. The most common buildings prone to leaking are those built between the late 1980s and mid-2000s using a monolithic cladding system, which gave the exterior walls a smooth, unbroken appearance. Often, leaky buildings are commercial buildings or apartment blocks, but houses can also suffer issues, especially those that have not been built to a high standard.
In these buildings, moisture can get trapped between the cladding and the inside walls, and without adequate ventilation, it can lead to issues including damp and mould.
Signs of a building that isn't weathertight include:
- rust or staining on the exterior walls
- cracks in the cladding
- no clearance between the ground and the cladding
- damp or rot around window and door frames
- lack of flashing around window and door frames and pipework
- stains or mould spots on interior walls or ceilings
- spongy feeling in floors
- water damage to carpet or vinyl flooring
- a musty smell
- If in doubt, call us now, and we can talk you through the best course of action.
