5 Most Common Cladding Problems and How to Fix Them

As a property owner or manager, you know that your property’s exterior is its first line of defence against the elements. And while cladding plays a key role in protecting the underlying structure, it’s not immune to problems of its own. From water infiltration to unsightly stains, cladding issues can compromise your building’s integrity and appearance if left unchecked. In this post, we’ll explore the most common cladding problems and provide practical solutions to help you keep your façade in top condition. Let’s dive in!

Water Infiltration

One of the most prevalent and potentially damaging cladding issues is water infiltration. When moisture finds its way behind the cladding, it can lead to a host of problems, from rot and mould to structural damage.

Causes of Water Infiltration

  • Improper installation or sealing of cladding panels
  • Damage to the cladding surface, such as cracks or holes
  • Failure of flashing or other moisture barriers
  • Clogged or inadequate drainage systems

How to Fix Water Infiltration

The first step in addressing water infiltration is to identify and repair the source of the problem. This may involve:

  • Resealing joints and gaps between cladding panels
  • Replacing damaged panels or sections of the façade
  • Installing or repairing flashing and moisture barriers
  • Clearing gutters and drains to ensure proper water flow

If the infiltration has caused extensive damage, you may need to remove and replace affected sections of the cladding and underlying structure. It’s best to consult with a professional to assess the extent of the damage and develop an appropriate repair plan.

Fading or Discoloration

Another common issue, particularly with timber and some composite cladding materials, is fading or discoloration over time. While this may not pose a structural risk, it can detract from your building’s aesthetic appeal.

Causes of Fading

  • Prolonged exposure to UV radiation
  • Moisture damage or staining
  • Improper cleaning or maintenance
  • Natural weathering and ageing of the material

How to Fix Fading

The approach to addressing fading will depend on the severity of the issue and the type of cladding material. Some potential solutions include:

  • Applying a fresh coat of stain or paint (for timber cladding)
  • Using a colour-restoring product specifically designed for your cladding material
  • Replacing severely faded or discoloured panels
  • Installing a UV-resistant coating to prevent future fading

If you’re unsure about the best course of action, consult with a cladding specialist who can assess the condition of your façade and recommend an appropriate treatment.

Cracking or Warping

Cladding panels that are cracked, warped, or otherwise misshapen can compromise the integrity of your building’s exterior and allow moisture to penetrate behind the façade.

Causes of Cracking and Warping

  • Improper installation or support of the cladding panels
  • Exposure to extreme temperatures or moisture
  • Impact damage from hail, falling objects, or other sources
  • Natural expansion and contraction of the cladding material

How to Fix Cracking and Warping

Depending on the extent of the damage, you may be able to repair individual panels by:

  • Filling cracks with a suitable sealant or patching compound
  • Securing warped panels back into place with additional fasteners
  • Replacing severely damaged panels with new ones

To prevent future issues, ensure that your cladding is properly installed and supported, with room for natural expansion and contraction. Consider adding protective barriers in areas prone to impact damage, such as near trees or high-traffic zones.

Mould and Algae Growth

Mould and algae growth on cladding not only looks unsightly, but can also indicate underlying moisture problems that may lead to more serious issues down the line.

Causes of Mould and Algae

  • Persistently damp or shaded areas of the façade
  • Poor ventilation or drainage behind the cladding
  • Accumulation of dirt, debris, or organic matter on the surface

How to Fix Mould and Algae Growth

To remove mould and algae from your cladding, start by:

  • Cleaning the affected areas with a soft-bristled brush and a suitable cleaning solution (follow the manufacturer’s guidelines for your specific cladding material)
  • Ensuring proper ventilation and drainage behind the cladding to prevent future growth
  • Trimming back nearby vegetation to allow more sunlight and airflow

If the growth is extensive or keeps recurring, it may be a sign of a more serious moisture issue that requires professional attention.

Loose or Detached Panels

Over time, the fasteners or adhesives holding your cladding panels in place may fail, leading to loose or even completely detached sections of the façade.

Causes of Loose Panels

  • Improper installation or inadequate fastening methods
  • Exposure to strong winds or impact damage
  • Deterioration of the cladding material or supporting structure

How to Fix Loose Panels

If you notice loose or detached cladding panels, it’s essential to address the issue promptly to prevent further damage. This may involve:

  • Securing loose panels with additional fasteners or adhesives
  • Replacing damaged or missing fasteners
  • Installing additional support structures behind the cladding

In some cases, you may need to replace the affected panels entirely to ensure a secure and seamless façade.

Final Thoughts

Ultimately, while cladding isn’t always immune to damage, regular inspections and prompt repairs can prevent minor issues from escalating into major headaches.

Of course, choosing the right cladding material is also essential for minimising maintenance and ensuring long-term durability. If you’re considering a cladding renovation or new installation, be sure to explore our guide on understanding the different types of cladding and their unique benefits.
