Installing weatherboard cladding is essential for many homeowners who want to protect their homes from the elements. Whether you’re updating your exterior or repairing existing cladding, getting the installation right can prevent moisture damage and improve the durability of your property.
This guide will explain the different types of weatherboard materials, the installation process, and the key considerations to remember.
Let’s get straight to the point.
Weatherboards are angled pieces of wood, metal, or plastic installed at the base of doors to prevent moisture and water from seeping in and protect the structure from damage. Common types include wooden, fibre cement, and uPVC weatherboards, each with benefits and drawbacks.
Proper installation is key to preventing moisture problems, such as efflorescence and wood rot, and ensuring durability. Installing weatherboards involves preparing the surface, cutting the material, securing it, and applying sealant.
Regular maintenance, such as repainting wooden weatherboards or checking uPVC for cracks, is essential to keeping them effective. Weatherboard problems like water infiltration, wood rot, and cracking can be addressed with waterproof sealants, replacing damaged boards, and routine inspections.

What Is A Weatherboard?
A weatherboard is an angled or bevelled piece of wood, metal, or rigid plastic installed at the bottom of a door to prevent moisture and water from seeping into the structure. It acts as a barrier between the door and the ground, stopping rain from entering and causing decay in wooden doors or damage to other materials.
Many doors, especially composite and uPVC doors, have built-in seals that prevent moisture from entering. However, these seals can wear out, compress, and lose effectiveness over time. This is where weatherboards become invaluable, offering extra protection, particularly for wooden doors more vulnerable to moisture damage.
Types of Weatherboards
- Wood: Often used for traditional or wooden doors. Requires regular maintenance.
- Metal: Durable and often used in modern constructions.
- Rigid Plastic (uPVC): Common in modern doors, lightweight, and low-maintenance.
Key Steps In Installing Weatherboards
Installing weatherboards on doors or exteriors is essential for protecting the structure from weather elements, including wind, rain, and temperature variations. Ensuring a precise installation is crucial for creating a durable, watertight seal that prevents moisture damage. Here are the main steps:
1. Preparation
Before starting the installation, make sure the working surface and the weatherboard itself are prepared:
- Surface Cleanliness: Ensure the surface where the weatherboard will be installed is clean and completely dry. A dirty or damp surface can hinder adhesion and compromise the longevity of the installation.
- Measurement: Accurately measure the door frame width to determine the required length of the weatherboard. This step is vital for achieving a precise fit.
- Protection for Wooden Doors: Apply a coat of primer and paint before installing the weatherboard on a wooden door. This protective layer prevents moisture from seeping into the wood, which can cause swelling, warping, or rotting over time.
2. Cutting The Weatherboard
Properly cutting the weatherboard to size ensures it fits seamlessly across the door’s width:
- Measuring and Marking: Mark the weatherboard according to the door frame width, ensuring accuracy in measurements.
- Allow for Expansion: Cut the weatherboard slightly shorter than the actual width of the door frame to accommodate natural expansion and contraction due to temperature changes. This prevents cracking and misalignment that could lead to leaks.
- Safety Precautions: When cutting, use appropriate safety gear, such as gloves and eye protection, especially if working with hardwood or materials that produce dust.
3. Fitting The Weatherboard
Securing the weatherboard effectively is crucial for its longevity and performance against the elements:
- Positioning: Carefully place the weatherboard at the base of the door. Ensure it covers the gap between the door and the floor, preventing water ingress and draughts.
- Fastening: Depending on the material, fasten the weatherboard with screws or nails. Screws are often preferable as they provide a tighter fit and greater durability, particularly for external doors exposed to weather.
- Sealing: After fastening, apply a high-quality exterior-grade sealant around the edges of the weatherboard. This step is vital for preventing water from seeping through tiny gaps, particularly in areas where the weatherboard meets the door frame. Proper sealing also protects against moisture infiltration, which can lead to mould, wood rot, and insulation issues.
4. Final Touches
Adding the finishing touches enhances the appearance of the weatherboard and ensures all gaps are sealed effectively:
- Painting or Staining: If you’ve installed a wooden weatherboard, apply a coat of paint or stain to match the door’s finish. This step enhances the aesthetic appeal and adds another protective layer against weathering and fading from UV exposure.
- Inspection: Check for any gaps, loose fittings, or irregularities along the edges of the weatherboard. Adjust or re-fasten screws as needed to ensure a tight fit. Inspecting areas needing additional sealant is essential to maintain the weatherboard’s watertight function.
- Maintenance Tips: Periodic checks are recommended to ensure the sealant remains intact and the weatherboard performs optimally.
Maintenance Of Weatherboards
Regular maintenance is essential for weatherboards to remain effective. Depending on the material, weatherboards can be affected by UV light, temperature changes, and general wear and tear.
- Wooden Weatherboards: Require regular painting or staining to maintain their protective finish. Check for any signs of rot or damage, especially after heavy rainfall.
- Fibre Cement Weatherboards Should be inspected for cracks or chips compromising their waterproofing. Ensure that the protective coating is intact.
- uPVC Weatherboards: Clean periodically with soapy water to remove dirt and debris. Inspect for any cracks caused by temperature fluctuations.
Common Weatherboard Problems
Weatherboard homes can be durable, but if not installed or maintained properly, they may encounter several issues:
- Water Infiltration: Gaps during installation or worn-out sealants can allow water to seep in, damaging the structure.
- Rotting Wood: Wooden weatherboards that aren’t treated or regularly maintained can rot over time, compromising their integrity.
- Warping and Cracking: uPVC and fibre cement boards can warp or crack due to temperature fluctuations, particularly in extreme weather conditions.
- Installation Issues: Improper installation can trap moisture beneath the weatherboards. This trapped moisture can lead to problems like efflorescence (white staining), peeling paint, and rot. To avoid these issues, it is important to follow the manufacturer’s instructions and ensure all joints are properly sealed during installation.
By addressing these common problems and following best practices for installation and maintenance, homeowners can prolong the life and performance of their weatherboard homes.
Solutions For Common Problems
- Waterproof Sealant: Regularly apply waterproof sealant to prevent water from entering through gaps.
- Replacement: Replace any damaged or cracked weatherboards to prevent further issues.
- Routine Inspections: Conduct regular inspections, especially after adverse weather conditions, to identify and address problems early.
Weatherboard Designs And Materials
1. Wooden Weatherboards
Wooden weatherboards are popular in Australia for their natural aesthetic and versatility. They are commonly made from radiata pine, western red cedar, or spotted gum.
- Pine: Requires painting or staining to protect against UV damage, moisture, and decay.
- Cedar and Spotted Gum: These woods can be left untreated but will naturally weather and discolour over time.
Wooden weatherboards come in various profiles and can be installed horizontally, vertically, or diagonally. To ensure durability, selecting and treating wood according to AS 1684 (for timber framing) and AS 5604 (for timber durability) standards is important. These standards guide choosing timber suitable for the climate and conditions specific to different regions across Australia.
2. Bevelled Back Wooden Weatherboards
Bevel-back weatherboards are a widely used horizontal cladding. While they provide a classic look, they can allow air leakage through the laps, potentially allowing water to penetrate if not installed correctly.
3. Vertical Shiplap Wooden Weatherboards
Shiplap boards have a snug fit and limit air and water infiltration. However, slight gaps can form over time, allowing air and moisture to pass through.
4. Fibre Cement Weatherboards
Fibre cement weatherboards are a popular modern alternative due to their durability and low maintenance. These boards are often designed with specific profiles that imitate the appearance of traditional wood.
- Advantages: Resistant to water absorption, more stable than wood, and less likely to warp.
- Disadvantages: They require a special waterproof coating and precise installation per the manufacturer’s guidelines.
5.uPVC Weatherboards
uPVC weatherboards are lightweight and durable and available in various colours and profiles. They are easy to install and provide excellent water resistance.
- Advantages: Low maintenance, resistant to UV damage, and suitable for direct repair on low-risk buildings.
- Disadvantages: Susceptible to temperature fluctuations, which can cause cracking or warping over time.
