Exterior Cladding: What It Is and What It Does

Exterior cladding is a layer of material - uPVC, timber, fibre cement or composite board - fixed over the outer face of a wall. Its job is to deflect rain, manage wind-driven moisture and give the building a clean, finished appearance. When it's working properly, the wall behind it stays dry and the interior stays warm. When it fails, moisture gets into the structure and the damage can spread quickly.

Cladding on residential properties is exposed to wet winters and strong winds. Over time, boards can crack, warp, fade or pull away from fixings. The question most homeowners face eventually is whether a targeted repair will do, or whether the whole lot needs to come off and be replaced.

When Repair Makes Sense

Repair is the right answer when the damage is limited in scope and the rest of the cladding is structurally sound. There's no point in spending money on full replacement if three boards are cracked and the remaining twenty are fine. A good contractor will identify and fix isolated problems without pushing you toward a larger job.

Repair tends to work well in these situations:

• One or a few boards are cracked, split or missing - perhaps from an impact or a branch coming down in high winds.
• A section of trim or corner piece has come loose or broken away, but the boards behind it are intact.
• A fixing has failed on one area and boards have begun to pull away, but the rest of the system is secure.
• A small area of sealant around a window reveal has failed and is letting in water, but the cladding itself is undamaged.

In these cases, matching replacement boards can often be sourced, the damaged section removed and new boards fitted without disturbing the rest. With uPVC, colour matching can be tricky on older installations because fading means new boards may look noticeably brighter. A contractor should flag this before starting.

When Replacement Is the Better Option

Replacement makes more sense than repair when the problems are widespread or when the underlying installation has fundamental faults. Patching over a poorly installed system just defers the cost.

Consider full replacement when:

• Boards are warping, bowing or cracking across a large area - this usually means the original fixings or battens were inadequate, or a breather membrane was never fitted.
• There is damp in the wall behind the cladding - this suggests the system has been failing for some time and the structure may need attention before new cladding goes on.
• The original material is uPVC that has become brittle and discoloured after many years. uPVC doesn't have an indefinite lifespan, and widespread brittleness means the whole installation is near the end of its useful life.
• The fixings are corroded or the batten framework behind the boards is rotten - in this case, removing and replacing everything is safer than trying to work around it.
• You're planning to upgrade the material - for example, moving from uPVC to fibre cement or a composite board - because you want a different appearance or better long-term performance.

The Risk of Ignoring the Problem

Cladding failures don't stay contained. A cracked board or a failed sealant joint lets water into the cavity behind the cladding. If there's no breather membrane (common on older installations), that water has nowhere to go and begins saturating the wall. Saturated walls lead to damp internally, damage to insulation if any is present, and in timber-framed properties, the risk of rot in the structural frame. A repair that costs a few hundred pounds now can avoid a remediation job costing several thousand later.

Cladding is sometimes installed without a properly ventilated cavity. These installations can look acceptable from the outside while concealing moisture problems behind the boards. If a property has older cladding with no visible ventilation strip at the base, it's worth having it assessed.

What a Proper Assessment Involves

Before recommending repair or replacement, a contractor should inspect the cladding up close - not just from the pavement. That means checking the fixings, pressing boards to test for movement, looking at all junctions with windows and roof edges, and ideally removing one board in a suspect area to check what's behind. If a contractor quotes for replacement without any of this, ask why.

Costs: Repair Versus Replace

Isolated cladding repairs - replacing a few boards and re-sealing junctions - typically cost from around £200 to £800 depending on the material and access required. Full replacement on a semi-detached house runs from roughly £4,000 to £9,000, with fibre cement and composite materials at the higher end and uPVC at the lower. These are indicative figures; the actual cost depends on the size of the elevation, whether scaffolding is needed and the condition of what's behind the existing cladding.

If the wall behind has moisture damage, allow for remediation costs on top. A contractor who quotes for the new cladding without mentioning what they found behind the old boards is not giving you the full picture.

Choosing the Right Material If You're Replacing

Replacing cladding is an opportunity to choose a better material if the original wasn't performing well. uPVC is the lowest-cost option and needs almost no maintenance, but the appearance divides opinion and cheaper grades can become brittle. Fibre cement boards are durable, can be painted in a wide range of colours and look closer to traditional materials. Composite boards sit between the two in price and performance. Timber is an option for homeowners who want a natural look, but it requires regular painting or staining to stay in good condition.

The right choice depends on your budget, the style of the property and how much ongoing maintenance you're prepared to do. Ask the contractor to show you examples of each material on finished properties before you decide.

If you're unsure whether your cladding needs a repair or a full replacement, arrange a survey. A good survey inspects it properly, explains what it finds and sets out the options in writing.
