What Exterior Cladding Is and What It Protects Against

Exterior cladding forms a protective layer over your home's walls, keeping rain, wind and frost away from the underlying structure. It also gives properties a cleaner, more finished appearance.

When cladding is in good condition, it works quietly in the background. Problems become visible as boards split, warp, come loose, discolour badly or allow water to get in behind them. At that point, you face a choice: repair what is there, or strip it back and start again.

Why This Decision Matters

Getting the repair-versus-replace decision wrong costs money in one of two ways. Spending money on repairs to a system that is fundamentally failing means you will be back in the same situation within a few years. On the other hand, replacing perfectly sound cladding unnecessarily is an expensive job that did not need doing yet.

The right answer depends on the age of the existing system, the extent of the damage, the condition of the battens and fixings beneath the boards, and whether there is any moisture damage to the wall behind. None of these factors can be assessed properly without a hands-on inspection.

When Repair Is the Right Call

Repairs make sense when the damage is genuinely localised and the rest of the system is in sound condition. Specific situations where repair is appropriate include:

• One or two boards that have been cracked by impact damage while the surrounding boards are secure and undamaged
• A failed sealant joint around a window or at a corner junction that has allowed water ingress, where the boards themselves are intact
• A small section of loose cladding caused by a fixing failure, where the battens behind are dry and sound
• Surface discolouration or algae growth on otherwise structurally sound boards, which can often be treated with cleaning and, on timber, a fresh coat of stain or paint

For uPVC systems, individual boards can often be sourced to match and slotted in without disturbing the rest of the installation. With timber, matching the profile is usually straightforward, though matching the weathered colour takes time. Composite boards vary more by manufacturer and age, and finding an exact match for older systems is not always possible.

A repair on localised damage to an otherwise sound system can extend the working life of your cladding by several years. It is a sensible approach when the fundamentals are good.

When Replacement Makes More Sense

There are situations where patching and repairing becomes a false economy. Replacement is generally the better option when:

• The damage is widespread across a significant portion of the clad area, not contained to one or two boards
• The battens behind the cladding have rotted or are no longer holding fixings securely. This is more common than people expect, particularly in older timber-battened systems where ventilation was not built in correctly
• There is evidence of persistent damp in the wall behind the cladding. Repairing the cladding without addressing what has caused the moisture to get in simply delays the next problem
• The existing boards are brittle, heavily faded or distorted across the whole elevation, indicating the material has reached the end of its serviceable life
• The original installation was poorly done - boards not properly overlapped, inadequate fixings or missing ventilation - and the issues are structural rather than surface-level

An honest assessment of an ageing or failing system will sometimes reveal that the cost of doing the repairs properly, including addressing the underlying issues, is not far short of the cost of a clean replacement. In that case, starting fresh with a new system makes more financial sense and gives a better long-term outcome.

The Importance of What Is Behind the Boards

This point deserves its own section because it is frequently underestimated. The boards themselves are only part of the story. Behind them sit the battens, the fixings and, in some cases, an insulation or breather membrane layer. If water has been getting in behind the cladding for any length of time, timber battens can rot, and the wall surface can be damaged.

When assessing the scope of a repair or replacement, removing a sample section of boarding is the only way to see what condition the underlying structure is in. If any contractor proposes extensive repairs without checking what is behind the boards, that should prompt a question about how they know the substrate is sound.

Where battens need replacing alongside new boards, this adds to the cost but is not optional. Fixing new cladding to rotten or failed battens means the new installation will fail prematurely.

Typical Costs: Repair Versus Replacement in Context

Repair costs depend heavily on how easy the damaged section is to access and whether the existing boards can be matched. A straightforward single-board replacement on an accessible wall might cost a few hundred pounds including access. More involved repairs - multiple boards, junction resealing, replacing failed battens - can run into the thousands depending on the area.

Full replacement of exterior cladding typically costs in the range of £50-£140 per square metre installed, depending on the material chosen. uPVC sits at the lower end of that range; quality timber and composite systems sit higher. These figures are for the boards, battens, fixings and trims, with the wall surface in reasonable condition behind.

If the wall itself needs attention before new cladding can go on - cracked render made good, damp treated - that work is additional and should be quoted separately so you can see clearly what you are paying for.

How to Get a Useful Assessment

When you ask a contractor to look at failing or damaged cladding in Dickleburgh, ask them to explain specifically what is wrong, whether the battens and fixings behind have been checked, what the cause of the problem is, and why they are recommending repair or replacement. The reasoning matters as much as the recommendation.

A diagnosis that consists of nothing more than "those boards need coming off" without any explanation of why, or without checking the substrate, is not a thorough assessment. You should come away from a survey with a clear understanding of what has failed, why it failed, and what the proposed work will actually fix.
