Exterior cladding is a weather-resistant outer skin fixed to the walls of a building. It keeps rain and wind away from the structural wall, can carry insulation within its build-up, and changes the appearance of a property. Systems range from traditional timber featheredge boarding through to composite, fibre cement, and metal panels. Each material has its own lifespan, maintenance needs, and installation requirements.
For many homeowners in Cambourne, the question is not which new cladding to choose - it is whether the cladding that is already there needs a repair, or whether the money is better spent replacing the whole system.
Cladding does not usually fail all at once. The warning signs tend to build gradually, and catching them early is the difference between a modest repair and a full-scale replacement. Look out for:
Any one of these issues warrants a closer inspection. Several of them together usually means the system has been underperforming for some time.
Repairing rather than replacing cladding makes sense when the damage is localised and the underlying framework and membrane are still sound. A typical scenario is a run of boards on one elevation that has taken the worst of the weather while the other sides remain in good condition. Replacing those boards, treating the battens, and repainting the repaired section to match is a fraction of the cost of stripping the whole building.
Repair is also the right answer when the cladding system is relatively new and the problem stems from a specific fault - a flashing that was not fitted correctly at a window head, for example, allowing water to track behind two or three boards. Fix the flashing, replace the damaged boards, and the rest of the system can continue as normal.
A partial repair on timber cladding typically costs from £300 to £800 for a small area, depending on access and the number of boards involved. That is obviously subject to the specifics of your property and the extent of the damage, but it is a useful ballpark when comparing the options.
There are situations where continuing to repair is false economy. If the timber behind the face boards is extensively rotted, if the breathable membrane has deteriorated and is no longer waterproof, or if the batten framework has moved or failed, individual board replacement will not solve the problem - it will just delay it.
Full replacement also makes more sense when:
A full reclad of a typical semi-detached house in the Cambridge area costs roughly £8,000 to £20,000 depending on the material chosen, the height and complexity of the building, and whether insulation is included. That range is wide because the variables are significant - a straightforward bungalow with easy access is very different from a two-storey property with complex roof junctions.
If replacement is the right path, the choice of material matters. Each system has real strengths and real drawbacks that affect both cost and long-term performance.
Timber featheredge is the most familiar choice and suits traditional-style homes well. Treated softwood is the affordable starting point, but it needs painting or staining every five to ten years to stay in good condition. Hardwood and modified timber boards need less maintenance but cost more upfront. Timber cladding installed and maintained correctly typically lasts 25 to 30 years.
Composite cladding removes most of the maintenance burden. It will not rot, split, or need repainting, and the colour is consistent through the board rather than just on the surface. It costs more than treated softwood to install - typically £80 to £160 per square metre fitted - but the reduced maintenance cost over 20 or 30 years can offset the difference.
Fibre cement is non-combustible and dimensionally very stable, meaning it does not expand and contract with temperature changes in the same way timber does. It is an increasingly popular choice on residential projects, particularly extensions and detached garages. Installed cost is typically £90 to £180 per square metre.
Metal cladding suits contemporary architecture and outbuildings. Aluminium is lightweight and corrosion-resistant; steel panels offer a more industrial finish. Metal systems tend to be at the higher end of the price range but have very long service lives when the coating is maintained.
When weighing repair against replacement, ask yourself three questions. First, is the damage contained to the boards and surface only, or has it reached the membrane and battens? Second, how old is the existing system, and is it likely to need further repairs within the next five years? Third, are you planning other work on the property - an extension, a loft conversion, or significant internal renovation - that would benefit from improved external insulation at the same time?
If the damage is surface-only and the system is less than halfway through its expected life, repair is almost always the right answer. If the damage is deeper or the system is ageing, getting a proper assessment will tell you whether you are pouring good money after bad.
Whether you repair or replace your cladding, the soffit boards under the eaves, the fascias at the roof line, and the bargeboards on any gable ends should be checked at the same time. They are part of the same weather-resistant envelope and they are often the first to show rot or paint failure. If scaffolding is going up for a cladding project, that is the practical moment to address them - not as a separate job later.
The only way to know for certain whether repair or replacement is the right option is to have someone who knows cladding look at the wall properly - not from the ground, and not from photographs.
