Exterior cladding is one of the harder-wearing parts of a home's exterior, but it does not last forever. Boards split, fixings corrode, joints open up, and colours fade. When problems appear, the first question is always the same: is it worth repairing what is there, or is it time to strip it back and start again?
Dereham Roofers works across Swaffham and mid-Norfolk, including Dereham, Fakenham, Watton, North Elmham, Hingham, Shipdham, Swanton Morley, Beetley, and nearby villages. We fit and replace timber, composite, and fibre cement cladding, and we are straightforward about which route makes financial sense for a given job.
Cladding does several jobs at once. It protects the underlying wall structure from wind, rain, and UV exposure. It contributes to the thermal performance of the building envelope when fitted with insulation behind. And it defines how the property looks from the street. When cladding fails in any of these functions, the consequences work their way inward - damp patches on internal walls, heat loss, and deterioration of the wall structure behind.
A well-installed cladding system uses treated battens fixed to the wall, a breather membrane in many cases, and boards or panels secured with stainless steel fixings to prevent rust staining. The base of the system allows moisture to drain rather than collect. Getting those fundamentals right at the start is what separates a twenty-year job from one that needs attention again within five.
These are honest typical UK price ranges. Actual costs vary with wall condition, access requirements, any scaffolding needed, and the specific product selected.
This is the question that drives most cladding enquiries, and the answer is rarely obvious from the outside. Some situations are straightforward; others need an honest assessment of what is happening behind the boards before anyone can give a useful recommendation.
Repair makes sense when the damage is genuinely limited in extent and the rest of the system is performing well. If a handful of boards have split, a section of batten has rotted, or fixings have failed in one area, targeted replacement of those elements is entirely reasonable. The key question is whether the surrounding cladding is in sound condition and correctly installed. If it is, there is no point in stripping a whole elevation for the sake of a few damaged boards.
Timber cladding lends itself to repair more readily than other materials because individual boards can be sourced and replaced. A good match in profile and species is important; a patch of noticeably different timber will stand out unless the whole elevation is repainted or treated after the repair. Composite and fibre cement boards can also be replaced individually, though matching discontinued profiles or colours from older installations can sometimes be difficult.
Repair is also appropriate when the problem is one of surface finish rather than structural failure. Peeling paint on timber that is otherwise sound, for example, is a maintenance issue rather than a cladding failure. Strip back, treat any areas of incipient rot with preservative filler or a consolidant, and repaint. That is straightforward work that extends the life of perfectly good boards.
There are situations where repair is effectively throwing good money after bad. A common problem is widespread board failure - where more than a third to a half of the boards on an elevation are cracked, split, cupped, or showing signs of moisture ingress. At that point, the cost of replacing boards piecemeal approaches the cost of full replacement, and you do not get the benefit of a fresh, correctly installed system underneath.
Full replacement also becomes the better option when the battens behind the cladding are failing. Battens rot when the cladding above them has been allowing water ingress for an extended period, or when they were installed without adequate treatment in the first place. You cannot simply re-board over rotten battens; they must come out. Once the battens are off, the wall behind can be properly inspected, any underlying masonry or render issues can be dealt with, a new membrane can be fitted, and fresh treated battens can go up before any new boards are fixed.
Hidden batten rot is one of the more expensive surprises in cladding work, because it is not visible until the old boards come down. Any contractor assessing existing cladding for repair should probe the base of the battens where moisture is most likely to have accumulated, and check for soft spots around window and door frames where water tends to track in at junctions.
With older cladding installations, finding a matching board profile can be genuinely difficult. Composite cladding in particular has evolved quickly over the past fifteen years, and profiles from early-generation products are often no longer manufactured. The same applies to certain fibre cement ranges. If you cannot match the existing boards closely, a partial repair will always be visible - and on an elevation that faces the street, that matters.
In these cases, replacing the whole affected elevation with a current product is often more cost-effective than hunting down a close-but-not-quite match. It also gives you a consistent, correctly installed system across the full face rather than a patchwork of old and new with potentially different performance characteristics.
Whether you are leaning towards repair or replacement, these are the questions worth putting to any contractor before you agree to work:
A contractor who can give clear, specific answers to these questions without hesitation is demonstrating that they understand the work properly. Vague answers are a reason to pause.
A full cladding replacement is not simply a case of pulling off the old boards and nailing up new ones. The correct sequence matters. Old boards and battens are removed carefully to avoid damaging the wall behind. The wall is inspected for damp, spalled masonry, failed mortar, or cracked render, and any issues addressed before anything goes back on. New treated battens are fixed plumb and level. A vapour-permeable breather membrane is fitted where the system and wall type require one. Boards are installed from the bottom up with the correct fixings and overlaps. Trims, sills, and flashings are fitted at every junction - windows, doors, eaves, and any interface with roof elements.
The finished result should be tight, clean, and properly weatherproofed at every edge. Ask the contractor to walk you through each of these steps before work starts so there are no surprises about what is and is not included.
Because Dereham Roofers works in roofing as well as cladding, we pay particular attention to where the two meet. The junction between cladding and eaves, verges, or flat roof edges is a common source of water ingress if it is not properly detailed. Flashings at these points must be correctly lapped and sealed. If a previous contractor left these junctions poorly finished, that is often where the original moisture problem began.
If your cladding assessment reveals roofline issues at the same time, it is worth asking whether both can be dealt with in a single visit rather than by separate contractors working around each other.
