What Exterior Cladding Does and Why It Matters

Exterior cladding is the outer skin of your home. It keeps wind, rain and frost out of the wall structure beneath, and when it fails, water finds its way into the fabric of the building. Repairs that might have cost a few hundred pounds can become thousands once damp reaches the internal wall, insulation or structural timbers.

Ely Roofers installs and replaces exterior cladding on homes in and around Wimblington. We cover the full job: stripping the old material, checking what is underneath, and fitting the right system for the building.

Warning Signs You Should Not Ignore

Cladding problems rarely appear overnight. They build up over months or years, and by the time a homeowner notices something is wrong, the damage has often gone deeper than the surface. Knowing what to look for means you can act before the repair bill grows.

• Cracking in render or mortar joints. Hairline cracks are normal on older render, but cracks wider than a couple of millimetres let water in. Frost then expands that water, widening the crack further with every cold night.
• Bulging or hollow-sounding panels. If you tap a rendered wall and hear a hollow thud rather than a solid knock, the render has lost its bond with the substrate behind it. That section is likely to fall away.
• Staining or tide marks on the wall face. Dark vertical streaks below window sills or around fixings are a sign water is tracking down the face of the cladding rather than being shed away from the building.
• Bubbling or flaking paint on internal walls. When damp crosses from the outer skin into the wall cavity or the inner leaf, it often shows up inside the house first as paint bubbling, plaster staining or a musty smell in a room.
• Rot in timber boards or window surrounds. Timber cladding that has not been maintained properly absorbs water at the end grain and at joints. Once rot sets in, the affected board cannot simply be repainted - it needs replacing.
• Loose or missing sections after wind or frost. Wind-driven rain and frost cycles are the most common causes of mechanical failure in cladding systems. If sections are moving or missing, the fixings behind them have likely corroded or pulled free.

What Causes Cladding to Fail?

Understanding the cause is just as important as fixing the symptom. The same problem recurring after a repair usually means the root cause was not dealt with first time round.

Age and natural weathering are the most straightforward cause. Render and painted timber have a finite life, and older properties that have never had their cladding system upgraded will eventually reach the point where patching is no longer cost-effective.

Poor original installation shortens that lifespan significantly. Render applied too thick in one coat, timber boards fixed without adequate back-ventilation, or panel systems with gaps at the joints all allow moisture to accumulate where it should not.

Movement in the substrate causes cracking even in newer systems. All buildings move slightly as temperature changes, and cladding that was not installed with enough flexible fixings or movement joints will crack at the weakest points first.

Failed or missing flashings are a frequently overlooked cause of localised water ingress. Where cladding meets a window frame, a roof verge, or a parapet wall, a flashing or sealant joint is needed to bridge the gap. When that seal breaks down, water enters at exactly the point where it is hardest to spot from ground level.

Vegetation is another factor. Ivy and other climbing plants may look attractive but their roots and tendrils work into cracks and joints, slowly forcing open gaps in the cladding skin. Removing the plant and repointing or patching behind it is the only long-term solution.

When Repair Is Enough and When Replacement Makes More Sense

Not every failing cladding system needs to come off entirely. Where the damage is localised - a single section of bulging render, a handful of rotten boards in an otherwise sound elevation - targeted repair is the practical choice. We will tell you honestly which category your property falls into.

Full replacement becomes the better option when the underlying fix has failed across a wide area, when the existing system has passed its practical life, or when a property owner wants to upgrade insulation or change the appearance of the building at the same time. Stripping everything back gives a clear view of the wall behind, which is also an opportunity to spot any structural issues that a surface repair would simply hide.

What a Good Cladding Job Involves

Whatever system is being fitted, the preparation matters most. The wall behind needs to be dry, structurally sound and clean before any new material goes on. Rushing that stage produces the same failure in a shorter time.

Fixings should be the correct type for the substrate - a stainless steel or galvanised fixing into masonry behaves very differently to a standard screw into timber batten. Using the wrong fixing is a common reason cladding panels loosen within a few years of being fitted.

Drainage and ventilation behind the cladding layer also need to be right. Cavity-drained systems rely on air movement to keep the back face of the boards or panels dry. Block off the bottom or top of the cavity and moisture will sit there.
