What exterior cladding is for

Cladding gives the outside of a wall a durable, weatherproof skin. It protects the structure behind it from rain, reduces maintenance on exposed masonry or timber frames, and changes the appearance of a building significantly. We fit and repair cladding on homes and outbuildings based from Haverhill, and cover Sawston and the surrounding villages.

The material you choose affects cost, maintenance, longevity and the way the finished wall looks. There is no single right answer, and anyone who tells you one material is always better than the others is simplifying things too much. Here is what you actually need to know about each option.

Timber cladding - character, but it asks something of you

Timber is the traditional choice and still the most popular for residential projects where appearance matters. It is available as featheredge boards, shiplap, tongue-and-groove, or square-edged boards, and it can be painted, stained or left to weather to a natural grey.

Pros:

• Looks genuinely good on houses, extensions and garden buildings.
• Easy to work with on site - individual boards can be cut to length without specialist equipment.
• When a section gets damaged, you replace the affected boards only, not the whole panel.
• Sustainably sourced softwood and hardwood options are widely available.

Cons:

• Softwood cladding needs repainting or re-staining roughly every five to eight years if you want to maintain the colour and the protection. Leave it and the paint fails, then the timber follows.
• It must be back-primed on all faces before installation. Boards that are only painted on the face absorb moisture from the back and fail prematurely - this is a very common cause of early deterioration.
• Hardwoods such as oak are significantly more expensive than softwood, though they need less frequent treatment.
• Ground clearance matters. Timber cladding should finish at least 150mm above any surface that holds water, or the bottom boards rot within a few years.

Typical installed cost for painted softwood featheredge: around £80 to £120 per square metre, depending on profile and access.

Fibre cement cladding - low maintenance, predictable appearance

Fibre cement boards are made from a mix of cement, sand and cellulose fibre, pressed into boards that mimic timber profiles. The main brands produce boards in a range of finishes, including smooth painted, textured painted and wood-grain embossed.

Pros:

• Once fitted and painted, maintenance is minimal. The boards do not rot, do not absorb moisture and do not need regular re-treatment in the way timber does.
• They are resistant to insect damage and do not swell or shrink significantly with temperature change.
• Good performance around windows and other junctions where moisture ingress is a risk.
• Available in profiles that closely resemble timber from a normal viewing distance.

Cons:

• Heavier than timber, which affects handling on site and means fixings and batten specification need to be correct for the weight.
• Cutting requires dust control because the cement content produces fine particulate. This is a health and safety consideration for the installer, not a problem with the finished product.
• Up close, the embossed wood-grain finish does not fool anyone who looks carefully. If an authentic timber appearance matters, actual timber is better.
• If a board cracks from impact (a ladder falling against it, for example), the repair is a full board replacement rather than a local fill.

Typical installed cost for fibre cement weatherboard: around £90 to £130 per square metre, depending on the profile and the number of penetrations to work around.

Composite cladding - the long-life option

Composite boards are made from a mix of wood fibre and PVC or polymer, pressed into boards that look similar to timber. They are factory-finished in a colour-through material, so surface damage does not show raw wood beneath.

Pros:

• Very low maintenance once installed. No painting, no re-staining, and resistant to rot and insect damage.
• The colour is held through the board's thickness, so minor surface scratches are less visible than on painted materials.
• Good stability - far less expansion and contraction than solid timber.
• Most manufacturers publish independent test data for weathering and UV resistance.

Cons:

• Higher upfront cost than painted softwood. Typically £110 to £160 per square metre installed.
• The range of profiles is more limited than timber. If you want an unusual section, you may not find it in composite form.
• Quality varies significantly between manufacturers. Board density, UV stability and the fixing system all differ. It is worth checking whether the product has been independently tested for weather resistance before you commit.
• Expansion gaps are essential during installation. Boards fitted too tight will buckle in summer heat.

Which material should you actually choose?

If you want the best appearance and are happy to maintain it, painted hardwood or well-specified softwood is hard to beat. If you want to minimise future maintenance and the timber look is not critical, fibre cement or composite both perform well. For outbuildings and extensions where a strong visual result matters less than longevity, composite is often the most practical choice over a twenty-year horizon.

For any project in Sawston or nearby, the honest answer starts with a look at your wall - what it is built from, what access is like, what is happening at the junctions with windows and the roof. The material choice follows from that, not the other way around.
