Recladding Costs For Monolithic Homes In NZ (2025)

Welcome to your go,to guide on understanding the real cost to reclad a monolithic house in New Zealand. If you own a home built in the 1990s or early 2000s with monolithic cladding, you’ve likely heard concerns about water damage, weather,tightness issues, and declining resale value. Recladding isn’t just a cosmetic fix, it’s a critical step in protecting your property’s structure and long term value. In this post, we’ll walk you through what monolithic cladding is, why recladding is often necessary, what influences the cost, and how much you should realistically expect to spend. Whether you’re weighing up quotes or just exploring options, this guide will help you make informed decisions.

On average, the cost to reclad a monolithic house in New Zealand typically ranges from $100,000 to $300,000, depending on the home’s size, level of damage, and cladding materials used. Key factors include labour, council consent, scaffold hire, and timber repairs. Prices may rise if hidden issues like rot or asbestos are found during the process.

What Is A Monolithic House?

A monolithic house is a type of home that features a solid, continuous exterior surface, usually made from plaster or similar materials applied over a sheet or panel system. These homes became popular in New Zealand during the 1990s and early 2000s for their sleek, modern look and cost effective construction.

Monolithic cladding gives the appearance of a smooth wall with no visible gaps, joins, or overlaps. While visually clean and modern, this style of construction has raised major concerns in recent years, especially due to poor weather tightness.

Common Materials Used In Monolithic Cladding

Most monolithic homes in New Zealand were built using one of the following materials.

•  Fibre cement sheets (like Harditex or Monotek)
•  Polystyrene panels with a plaster finish
•  Stucco (cement plaster applied over mesh or lath)

These materials are often coated with a textured plaster finish and painted to match the home’s design. The end result is a uniform exterior without the visible gaps found in traditional weatherboard or brick cladding.

 Why Monolithic Homes Are Prone To Leaking

The problem isn’t just the material, it’s how the system was built. Many monolithic houses were constructed without a proper drainage cavity between the cladding and the timber framing. That means any water that gets in can’t escape, leading to trapped moisture.

If there’s even a small crack in the exterior, around windows, doors, or rooflines, water can seep in and get stuck behind the cladding. Over time, this causes timber framing to rot. Because the damage happens behind the surface, it’s often not visible until the problem becomes severe.

This issue is known as leaky building syndrome, and thousands of monolithic homes across New Zealand have been affected.

How To Tell If Your Home Has Monolithic Cladding

Not sure if your home falls into this category? Here are a few signs.

•  Smooth, plaster,like exterior walls without joints or overlapping boards
•  Built between 1990 and 2004 (the peak period for monolithic construction)
•  No visible drainage or ventilation gaps in the cladding system
•  Painted stucco or plaster finish over large, flat wall areas
•  Soft or musty smell inside the home, especially near skirting boards or window frames
•  Hairline cracks on the outside walls, especially near windows or corners

If your home checks some or all of these boxes, it’s worth getting a professional inspection. Identifying monolithic cladding early can help you plan for maintenance or recladding before serious damage occurs.

Why Recladding May Be Necessary

If you own a monolithic,clad home, you may be wondering whether recladding is truly essential. The short answer: it often is. Recladding isn’t just about improving how your home looks, it’s about protecting your health, your investment, and your peace of mind. Here’s a closer look at why recladding may be necessary and what can happen if you delay the process.

Structural And Health Risks Due To Moisture Issues

Monolithic cladding systems, especially those built in the 1990s and early 2000s, were not designed with proper drainage or ventilation. Once moisture gets in, it often has nowhere to go. Over time, water can seep behind the cladding and soak into the timber framing. That moisture creates a perfect environment for timber rot and mold growth.

Rotten framing weakens your home’s structure, which compromises its safety. At the same time, mold and dampness can cause serious health problems for you and your family, especially for those with asthma or allergies. You may not see the damage at first, but the longer it goes unchecked, the worse, and more expensive, it becomes.

Long Term Damage And Insurance Complications

If water damage remains hidden for years, it can spread deep into the framework. What starts as a small moisture issue can turn into a full,blown structural repair job. That means higher costs, longer repair timelines, and more disruption to your life.

Many insurance companies are also cautious when it comes to monolithic homes. Some refuse to provide full coverage unless a reclad has already been completed. Others may not pay out for damage caused by long term moisture issues, especially if the cladding system is known to have problems.

Waiting too long to reclad could limit your insurance options, or leave you underinsured when you need help the most.

Legal And Resale Implications If Left Unrepaired

Buyers are more informed than ever. When they hear “monolithic cladding,” most immediately think of leaky homes. Even if your property hasn’t had issues, its resale value will likely drop due to buyer hesitation. Many banks won’t approve full mortgages on monolithic homes without proof of recladding or a clean building report.

If you decide to sell a monolithic home that hasn’t been reclad, you may be required by law to disclose past leaks, moisture damage, or non compliant repairs. This can create legal risks, lower offers, or even stop the sale altogether. Recladding helps eliminate those obstacles and gives potential buyers more confidence.

Council Requirements And Building Code Compliance

In New Zealand, any significant recladding work must meet the latest building code standards. That means you’ll need building consent before starting the job. Councils will inspect your property, review your plans, and make sure your new cladding system meets weather tightness requirements.

While this may sound like extra hassle, it’s a necessary step. It ensures your home is safe, legal, and protected from future damage. Once the reclad is complete and signed off, you’ll receive a Code Compliance Certificate (CCC), a must, have if you plan to sell or refinance your home. Choosing to reclad isn’t just a financial decision, it’s a safeguard for your home, your health, and your future. Whether you’re dealing with known issues or simply planning ahead, taking action now can help you avoid far greater costs and complications down the line.

Key Factors That Affect Recladding Costs

Recladding a monolithic house isn’t a one size fits all job. The final price can vary significantly from one home to another. Below are the key factors that influence how much you’ll end up paying. Understanding these will help you plan more accurately, avoid surprises, and make better decisions when budgeting for your project.

Size Of The House

The bigger the house, the higher the cost, simple as that. Larger homes require more materials, more labour, and often more time to complete. A small, single,storey home might be manageable within a modest budget, but a two,storey house with complex design features will naturally push the price up. Most builders calculate costs based on square metres, so the more surface area there is to reclad, the more you’ll pay.

Accessibility And Site Conditions

Is your home easy to access? Can scaffolding be set up without issues? If your property is on a slope, has limited access, or sits close to other buildings, expect to pay more. Difficult terrain or tight spaces can slow down work and increase labour costs. Site conditions also affect how materials are delivered and stored, which adds to overall complexity and time on site.

Extent Of Damage Discovered During The Process

This is often the biggest wildcard in any recladding job. Once the old cladding is removed, builders might find rotting timber, mold, or even structural damage. If this happens, repairs become unavoidable, and costly. You won’t always know the full extent of the damage until work begins, which is why it’s smart to set aside a contingency budget of at least 10% to 20% for surprises.

Type Of New Cladding Chosen

Not all cladding materials are priced the same. Some are more affordable but require regular maintenance, while others have a higher upfront cost but last longer and offer better performance. Popular options include.

•  Weatherboard (timber or fibre cement): classic and durable
•  Brick veneer: stylish but more expensive and labour,intensive
•  Modern plaster systems with cavity: visually similar to monolithic but far more reliable

Your choice of cladding will impact not just your budget, but also the home’s appearance, insulation, and future maintenance costs.

Labour And Material Costs In Your Region

Where you live in New Zealand plays a big role in pricing. Labour rates in Auckland or Wellington may be higher than in smaller towns. Material availability and transport costs can also vary. If your area is experiencing a construction boom, high demand can drive up both labour and material prices. Getting multiple quotes from local contractors helps you gauge realistic pricing.

Whether You’re Living In The Home During Work

Living in your home while it’s being reclad can reduce costs, but only to a point. If your presence delays work or limits access to certain areas, contractors may charge more for the added inconvenience. On the flip side, moving out means additional expenses like rent, moving costs, and storage. It’s a balance between comfort, safety, and budget, and worth considering carefully before work begins.

Average Cost Range To Reclad A Monolithic House In NZ

If you’re thinking about recladding your monolithic home, you’re probably asking the same question most homeowners do: How much is this really going to cost me? The answer depends on a few key factors, mainly how much damage your home has, what materials you choose, and where you’re located. But let’s break it down into ballpark figures to give you a clearer idea.

Basic Reclad With Minimal Repair

If your home is in good shape structurally and you’re recladding mostly for resale or peace of mind, you’re likely looking at a basic reclad. This involves removing the old monolithic cladding, checking the framing, and putting on a new complaint cladding system, without uncovering major damage.

• Estimated cost: $100,000 to $150,000
• Cost per square metre: Around $450 to $650

This range typically covers:

•  New cladding materials
•  Labour
•  Scaffolding
•  Basic timber repairs (if needed)
•  Council consent and inspection fees

This is usually for single, storey homes or smaller properties in good condition.

Moderate Reclad With Typical Damage

Most monolithic homes fall into this category. Once the cladding is removed, there are often signs of moisture damage or minor framing issues that need to be repaired. The builder may need to replace sections of timber, install new window flashings, or upgrade the wall system to meet current building code standards.

• Estimated cost: $160,000 to $250,000
• Cost per square metre: Around $650 to $950

This covers a more thorough rebuild, including.

•  Partial timber replacement
•  Upgraded insulation or wall systems
•  Replacement of outdated joinery (in some cases)
•  Delays from extra inspection or remediation work

This is common for two, storey homes or those built in high, risk zones with poor ventilation or drainage.

Full Reclad With Structural Repair

If your home has major structural damage, like widespread timber rot, failed cladding systems, or previous repair attempts that didn’t meet the code, you’ll need a full reclad with significant repair work. This is often the most expensive scenario.

• Estimated cost: $250,000 to $400,000
• Cost per square metre: $950 to $1,500

This includes everything from the moderate reclad level, plus.

•  Major framing replacement
•  Full window joinery upgrades
•  Architectural input and project management
•  Temporary accommodation (if the house is uninhabitable)

This is usually needed in homes where leaking has gone undetected for years.

Other Costs To Factor In

Even with clear estimates, there are extra costs many homeowners overlook. These can include.

• Scaffold hire: Can range from $10,000 to $25,000 depending on house height and access
• Window and joinery replacement: $1,000 to $2,500+ per window
• Building consent fees: Often between $5,000 and $15,000 depending on council
• Design and consultancy fees: Architectural drawings, engineers, and project managers may cost another $10,000 to $30,000
• Accommodation: If you have to move out, this could add thousands to your total cost

Recladding isn’t a small expense, but it’s often the best decision for protecting your home and securing its long term value. The key is to plan ahead, get professional advice, and prepare for surprises once the walls come down. Want a more accurate estimate? Talk to a reclad specialist in your area who’s worked on similar homes, they’ll give you a clearer view based on your home’s condition.

What’s Included In A Reclad Project?

When you’re preparing to reclad a monolithic house, it helps to know what the entire process involves from start to finish. Recladding isn’t just about putting on a new exterior. It’s a complex, step-by-step job that uncovers hidden issues, restores the home’s structure, and ensures everything meets building standards. Here’s what you can expect during a full reclad project.

Site Setup And Scaffolding

Before any cladding comes off, your building team will set up the site. This includes putting up safety barriers, installing scaffolding around the home, and laying down protective covers to prevent damage to the surrounding area. Scaffolding is a major part of the recladding budget, it allows workers to access all sides of your home safely and efficiently. For multi-story houses or homes on sloped sections, scaffolding costs will be higher.

Removing The Old Cladding

Once the site is ready, the team begins carefully removing the existing monolithic cladding. This part of the job must be done with precision. If not handled correctly, it could cause unnecessary damage to the internal structure. As the cladding comes off, it also reveals the real condition of the framing underneath. This is often where unexpected issues are discovered, such as timber rot or water damage.

Timber Framing Inspection And Repair

With the cladding removed, the timber framing is fully exposed. A qualified builder or building inspector will check for moisture, mold, decay, or any signs of structural weakness. If there’s damaged timber, it must be replaced before the new cladding goes on. These repairs are essential to ensure your home meets New Zealand’s building code and remains weather tight for years to come.

Installing The New Cladding System

After repairs are complete, the builders begin installing the new cladding. This could be a weatherboard, modern plaster systems with drainage cavities, or another compliant material. The key here is making sure the new cladding includes proper ventilation, flashing, and moisture barriers. These features were often missing in older monolithic homes, which is why they failed over time. A correctly installed system keeps your home dry, energy-efficient, and compliant with current standards.

Painting, Finishing, And Council Sign Off

The final stage of the reclad includes painting the new exterior (if required), installing trims, fixing window flashings, and sealing all edges. Once complete, the council will inspect the work to make sure it passes all required checks. After sign-off, you’ll receive a code compliance certificate (CCC), which proves your home has been restored to meet legal and safety standards. This certificate is important for future resale and insurance purposes.

Each of these steps plays a critical role in the success of your recladding project. Understanding what’s included helps you ask better questions, manage your budget wisely, and avoid surprises once work begins. If you’re planning a reclad soon, make sure you’re working with a team experienced in monolithic homes and fully transparent about the process.

Hidden Costs You Should Plan For

When you’re budgeting to reclad a monolithic house, it’s easy to focus on the main expenses, materials, labour, and council consent. But real-world projects often come with surprises that push the total cost higher than expected. To avoid getting caught off guard, you need to prepare for hidden costs that may surface once work begins. Here’s what to look out for.

Unexpected Timber Rot

Once the old cladding is removed, builders will inspect the timber framing underneath. If the house has suffered from long-term water ingress (common in monolithic homes), there’s a good chance some of the framing will be rotted or compromised. This isn’t always visible from the outside. Fixing it means replacing parts of the timber, and that adds both time and labour costs to your project. In many cases, rot repairs alone can add tens of thousands of dollars to your reclad budget.

Asbestos Removal (If Present)

Some older homes, especially those built before the 1990s, may contain asbestos in the cladding, soffits, or ceiling linings. If any asbestos is discovered, it must be removed by licensed professionals. This process is highly regulated in New Zealand and can’t be skipped or done cheaply. Testing, safe removal, and disposal come with extra costs and will likely delay the timeline.

Extended Consent Or Inspection Delays

Getting council consent is a required part of the recladding process, but it’s not always fast or predictable. If your plans are complex or if issues are found during inspections, delays can occur. These delays don’t just stall the work, they can also increase labour charges if builders are kept waiting or if scaffolding needs to stay up longer than planned. Delays also mean a longer disruption to your daily life.

Temporary Accommodation If Needed

In some cases, it may not be safe or practical to stay in the home during the recladding process. If the job involves removing large sections of cladding at once or if major structural repairs are needed, you may have to move out. Paying for short-term rental accommodation, even for a few weeks, can be a significant unplanned expense, especially in high-demand housing areas.

Project Management Or Architect Fees

Many recladding projects benefit from having a project manager or architect involved, especially when dealing with complex repairs or changes to the exterior design. While this professional input helps keep everything on track and up to code, it does come at a cost. Fees for project managers or architects can vary widely, but even basic oversight adds another layer to your overall budget.

Even with a detailed quote, you should allow a buffer, ideally 15–20% of your reclad budget, to cover these hidden costs. Being financially prepared means you can handle surprises without stress, delays, or cutting corners. A smart homeowner doesn’t just plan for what they can see, they plan for what might be uncovered once the walls come down.

Cost Saving Tips Without Cutting Corners

Recladding a monolithic house is a major investment. But that doesn’t mean you have to overspend to get it done right. If you’re a homeowner planning this kind of project, you can save a significant amount of money without putting your home’s quality or safety at risk. These tips are designed to help you cut costs wisely while still meeting New Zealand’s building standards and avoiding expensive mistakes down the line.

Get Multiple Quotes From Licensed Builders

Always get at least three detailed quotes before choosing a builder. This gives you a clear idea of the price range and helps spot any overcharging or lowball estimates. Make sure each quote includes everything: labour, materials, scaffolding, council fees, and estimated repair work. Avoid quotes that seem too good to be true, they usually are. Ask about the builder’s past experience with reclads and check their references or online reviews.

Ask For Fixed Price Contracts When Possible

A fixed-price contract locks in the cost of the project, giving you financial certainty and peace of mind. This protects you from sudden price hikes due to material increases or labour costs. It’s especially useful in large projects like recladding, where unexpected delays or changes can quickly drive up the bill. Be sure to review the contract carefully to understand what’s included and what isn’t.

Choose Cladding That Suits Your Budget But Meets Code

Not all cladding materials cost the same. You don’t have to choose the most expensive option to get good results. Weatherboard, fibre cement, and certain plaster systems can all meet the building code when installed correctly. Talk to your builder about cost-effective options that still deliver durability and weather tightness. The key is choosing materials that balance price, appearance, and long-term performance.

Work With A Builder Experienced In Reclads

Recladding is not a simple job. It’s a specialised process that involves dealing with potential moisture damage, hidden rot, and strict council inspections. Hiring a builder who’s already completed several reclads means fewer surprises, smoother consent approvals, and higher quality work. An experienced builder will also help you avoid unnecessary expenses, because they know what to expect once the old cladding comes off.

Schedule Work During Off-Peak Seasons

Timing matters. Builders are often busiest in spring and summer, which means higher demand and potentially higher prices. If possible, schedule your reclad during quieter months, like late autumn or early winter. This can sometimes reduce costs and give you better access to the builder’s top crew. Just be sure the work won’t be heavily affected by weather, and always choose materials suitable for cooler, damp conditions.

Using these strategies, you can manage your recladding project with confidence, knowing you’re making smart decisions that protect your home and your wallet. You’re not just saving money; you’re investing in a safer, more valuable property.

Is Recladding Worth The Investment?

Recladding a monolithic house might feel like a massive expense, but for many homeowners in New Zealand, it turns out to be one of the smartest long-term decisions. When weighing up the costs, it’s important to look beyond the upfront price and consider the value it adds to your property, both financially and emotionally.

Impact On Resale Value

One of the biggest reasons homeowners choose to reclad is to protect their property’s market value. In today’s real estate market, homes with monolithic cladding often raise red flags for buyers, especially when there’s no record of repair or recladding work. Even if your house has no leaks, the stigma alone can affect its selling price and time on the market.

Buyers want peace of mind. When they see a recently re-clad home, they’re more confident in making an offer. A completed recladding job signals that the home is safe, weather-tight, and up to code. This reassurance can often justify a higher asking price. Real estate agents regularly report that reclad homes attract more serious buyers and sell faster than similar properties that haven’t been updated.

Peace Of Mind From Moisture Protection

Beyond property value, recladding gives you something just as important, peace of mind. Monolithic cladding systems often trap moisture behind the walls, especially if there’s no proper drainage or ventilation system in place. Over time, this can lead to timber rot, mold growth, and serious health risks.

Recladding involves not just replacing the exterior, but also inspecting and fixing any hidden damage inside the walls. Once the new cladding system is installed, usually with a cavity system to allow for proper drainage, you can rest easy knowing your home is dry, healthy, and protected from the elements.

Improved Appearance And Curb Appeal

Let’s be honest, many monolithic homes look dated. The plain, flat exterior might have been trendy decades ago, but tastes have changed. Recladding is a great opportunity to modernize the look of your home. Whether you go for timber weatherboards, brick veneer, or a modern plaster finish with crisp lines, a new cladding system instantly updates your home’s appearance.

Improving the outside look of your home also boosts curb appeal. That matters not just for resale, but for how you feel coming home every day. It’s a visible, high-impact change that makes your property stand out in the neighbourhood.

Long-Term Cost Savings From Preventing Further Damage

Putting off recladding often leads to bigger problems. Moisture trapped behind old monolithic cladding doesn’t just go away, it gets worse. Over time, what starts as a small leak can cause widespread damage to timber framing, internal walls, and even flooring. Once the rot spreads, the repair bill climbs quickly.

By recladding early, you can catch these issues while they’re still manageable. That means fewer structural repairs, less disruption to your life, and lower costs overall. It’s not just a fix, it’s a way to future-proof your home against weather damage and code compliance issues down the road.

Recladding isn’t cheap, but it’s often worth every dollar. You’re not just replacing an exterior, you’re restoring your home’s health, safety, and value. Whether you plan to sell soon or stay for years, a proper reclad offers both short-term benefits and long-term protection.
