What Exterior Cladding Is and What It Does

Exterior cladding is a layer of boards or panels fixed to the outside of a building, covering the existing wall surface. It can go over masonry, old render, pebbledash or timber frame. The purpose is to seal out wind and rain, improve insulation where required, and give a clean, low-maintenance external finish that does not need painting every few years.

Cladding is widely used on homes across Norfolk - on gable ends, rear extensions, full elevations and outbuildings. The right system depends on the substrate beneath it, the look you want and what you are trying to solve. Understanding that helps you make a sensible decision rather than simply buying whatever a contractor first suggests.

The Main Cladding Materials Available

Timber is used, particularly on partial elevations or where a more natural appearance is important.

• uPVC cladding - typically £50-£90 per square metre installed. Available in a range of profiles and finishes including smooth and woodgrain effects. Virtually no ongoing maintenance. Lighter weight than composite and easy to work with on site.
• Composite cladding - typically £90-£160 per square metre installed, depending on board thickness and profile. A denser, more substantial feel than hollow-backed uPVC. Manufacturer finish on quality boards can last 20 years or more before attention is needed.
• Fibre cement boards - typically £80-£140 per square metre installed. A cement-based panel available pre-painted or for site painting. Heavy and rigid, with good fire resistance. Requires proper fixings for the substrate and sealed cut edges to perform correctly.
• Timber cladding - installed costs vary considerably, broadly £90-£200 per square metre depending on species and finish. Larch and western red cedar are popular choices. Timber needs treating every three to five years unless thermally modified or factory pre-finished with a durable coating.

These price ranges are indicative UK figures and will vary depending on access, wall height, the amount of preparation required and the complexity of the detailing around windows and doors.

What Good Installation Involves

Regardless of which material is chosen, the installation process follows the same core stages. Understanding these helps you ask the right questions of any contractor you approach.

• Substrate survey - the wall behind the cladding must be inspected for damp, cracks, rot (in timber-framed structures) or loose existing finishes before anything goes on over it.
• Breather membrane - a vapour-permeable membrane is fixed to the wall before the battens go on. This lets moisture vapour escape from the wall while keeping wind-driven rain out.
• Batten framework - horizontal or vertical battens create a ventilated cavity between the membrane and the back of the cladding boards. Ventilation prevents condensation accumulating behind the boards.
• Board fixing - boards are fixed with stainless steel or other non-corrosive fixings. Correct centres and edge clearances matter for the long-term performance of the boards.
• Detailing - trims, corners, window reveals and soffit junctions are where most installation problems appear later. Careful measuring, cutting and siliconing here is what separates a lasting job from one that lets water in within a few years.

Repair or Replace? The Core Question for North Elmham Homeowners

This is the decision many homeowners face, and it is rarely straightforward. Existing cladding that has been on a property for ten years or more will have weathered, and some of it may be showing signs of wear. The question is whether targeted repair makes sense, or whether stripping and replacing the whole lot is the better investment.

The honest answer depends on what is wrong, where the damage is, what material the existing cladding is made from and what your budget is. Below is a framework for thinking it through.

When Repair Is the Right Choice

Repair makes sense when the damage is genuinely localised - a small section of boards that have been physically damaged, a corner trim that has lifted, or a handful of boards that have discoloured or cracked while the rest of the elevation is sound. In these cases, replacing the affected section and re-sealing around it can restore the performance of the cladding at a fraction of the cost of full replacement.

Repair is also worth considering when the existing material is still in production and an accurate match is achievable. Fitting mismatched boards on a visible elevation looks poor and can be worse than leaving the original damage. Before committing to repair, ask your contractor to confirm they can obtain boards that genuinely match in profile, colour and finish.

Other situations where repair tends to make sense:

• A single elevation has taken impact damage (falling tree branch, vehicle contact) while the rest of the cladding is performing well.
• Seals around windows or doors have failed but the boards themselves are intact. Resealing and re-trimming these areas is straightforward work.
• Fixings have corroded and boards are loose but undamaged. Re-fixing with correct stainless fixings is a reasonable repair on otherwise sound boards.
• The property was recently clad and the issue is a defect in a small area of the original installation.

When Replacement Makes More Sense

Replacement becomes the better option when the damage is widespread, when the existing cladding is failing structurally, or when the material is no longer available in a matching specification. Replacing a patchwork of boards from different batches across a large elevation rarely looks acceptable and the cost of repeated repairs over time can exceed the cost of doing the job once.

Key indicators that full replacement is likely the right call:

• Widespread moisture ingress behind the boards. If a survey finds that damp has been trapped behind the cladding over a large area, the boards need to come off so the wall and substrate can be assessed and dried out before re-cladding. Fitting new boards over a wet wall stores up a serious problem.
• Batten rot. If the timber batten framework behind the boards has rotted - common on older installations where the membrane was inadequate or missing - the whole framework needs replacing anyway. Once the battens are out, replacing the boards at the same time is cost-effective.
• The material is discontinued or significantly changed. Cladding profiles and colour references change over time. If the boards fitted fifteen years ago are no longer made to the same specification, repairs will always show. At that point, replacing the full elevation with a consistent new system is the honest solution.
• Structural movement in the substrate. Cracks that have opened up in the wall behind the cladding, or evidence that the building has settled or shifted, need to be assessed and addressed before any cladding work is done. This is not a repair job - it requires a proper investigation first.
• Multiple failing sections across the elevation. If you are looking at damage in three or four areas of one elevation, the total cost of individual repairs often approaches or exceeds the cost of stripping and re-cladding. A single, properly installed replacement job also gives you consistent performance going forward.

The Borderline Cases

Some situations genuinely sit in between, and a trustworthy contractor should say so rather than defaulting to the higher-cost option. A common scenario is an older uPVC cladding installation where most boards are sound but a number of corner trims have split and three or four boards are discoloured. If the substrate is dry and the batten framework is intact, selective replacement of the affected pieces - with the best available colour match - may be entirely reasonable for a rear elevation that is not the main visual face of the property. On a front elevation, the bar for accepting a colour mismatch is higher.

Ask any contractor in this situation to show you the actual boards or samples they propose to use alongside the existing cladding before you approve the repair approach. If the match is close enough for your purposes, repair is a sensible saving. If it is not, you have the information to make an informed decision about going further.

Getting the Survey Right Before You Decide

The decision between repair and replacement cannot be made properly from a pavement inspection or a photo. The wall behind the cladding needs to be accessed and checked. At minimum, this means lifting a board or removing a trim to look at the membrane and battens. On a property where damp is suspected, a moisture meter reading of the substrate gives a much clearer picture than visual inspection alone.

Ask any contractor you invite to quote to tell you specifically what they found in the survey, not just what they recommend. "The boards need replacing" is not enough information. You want to know what condition the membrane is in, whether the battens are sound, whether there is any damp in the wall and whether there are any concerns about the substrate that need addressing before re-cladding. A contractor who cannot answer these questions specifically may not have looked carefully enough.

Costs: Repair Versus Replace in Realistic Terms

Repair costs vary enormously depending on the extent of the work. Replacing a single damaged board and resealing around a window might cost £150-£300 including materials and labour. Replacing a full corner section and associated trims on a gable might be £400-£800. These are rough benchmarks only - the actual figure depends on access, the material and the specific work involved.

Full re-cladding of a typical semi-detached house elevation might run to £3,000-£8,000 or more depending on size, height, material choice and preparation required. For a full house, costs for larger properties can go higher. These ranges assume work is carried out properly with correct preparation, membrane, ventilated battening and appropriate finishing.

If a quote for repair or replacement is significantly below these ranges, it is reasonable to ask in detail what is being included and what is not. The materials alone have a market cost that does not compress much.

Planning and Permissions

Most exterior cladding work on a standard house falls within permitted development rights and does not require planning permission. Listed buildings are always an exception and need listed building consent for any external alterations. Properties in conservation areas may also face restrictions on materials and colours. If your property in or around North Elmham falls into either category, check with the local planning authority before instructing any contractor to start work.

Finding Useful Information and Getting Quotes

When looking for information on cladding costs and contractors, it helps to know what questions to ask. Compare quotes on the basis of the same material specification, the same preparation work, the same finishing details and the same waste removal arrangements. A quote that lacks a written breakdown is harder to assess fairly against others.

Frequently Asked Questions

Can I clad over existing pebbledash?

Yes, in most cases. The pebbledash needs to be checked for stability first. Any loose or hollow sections should be made good, or the decision taken to hack it off completely before battening. Fitting cladding over actively failing render creates problems further down the line.

What is the most low-maintenance cladding option?

uPVC requires the least ongoing attention - an occasional wash down is typically all it needs. Quality composite boards are also low maintenance. Timber requires the most, needing treatment every few years unless you choose a factory pre-finished or thermally modified product.

How do I know if damp is getting behind my existing cladding?

Internal damp patches on an external wall, a musty smell in rooms on external walls, or visible staining or discolouration at the base of the cladding are all signs worth investigating. A contractor with a moisture meter can check the substrate without dismantling the whole installation.

Does new cladding need building regulations approval?

In most cases for a straightforward residential re-cladding, building regulations approval is not required. Where insulation is being added as part of the work - creating an external wall insulation system - the thermal performance implications may bring it within scope. Your contractor should flag this if it applies to your project.
