If you are weighing up exterior cladding options for your Bar Hill home, understanding what each material actually does in practice will help you make the right call.
Exterior cladding is not just about appearance. The material you choose determines how long the system lasts, how much maintenance it needs, how it performs in wet and frosty weather, and what it costs to install and to keep in good order. There is no single best option - the right material depends on your building, your budget and what you want from it over the next ten, twenty or thirty years.
Ely Roofers fits and replaces cladding systems on homes across Bar Hill and the wider area around Ely. We work with several different materials and will tell you plainly what each one involves, including the drawbacks, so you can make an informed decision.
Sand and cement render is a common finish on post-war housing. Applied in two or three coats over masonry, it is relatively inexpensive and provides solid weather resistance when done correctly.
Pros: Low material cost, widely understood by tradespeople, easy to patch in small areas, takes paint well.
Cons: Prone to cracking as buildings move with temperature change; cracks let water in and frost widens them quickly. Needs repainting every several years to remain weatherproof. Heavy - not suitable for all substrates without mechanical fixings. When it fails over a large area, the cost of stripping and re-rendering can be significant.
Sand and cement render suits properties where the wall behind is solid masonry in good condition and where the owner is prepared to carry out periodic maintenance. It is a practical, cost-effective choice when the budget for the initial job is the priority.
Modern thin-coat render systems use a polymer or silicone base rather than pure cement. They are typically applied over an insulation board fixed to the wall (these are called External Wall Insulation or EWI systems), giving the dual benefit of a new weatherproof skin and improved thermal performance in one job.
Pros: Flexible enough to resist the fine cracking that plagues cement render; many silicone finishes are self-cleaning to a degree; can improve wall insulation significantly; wide choice of texture and colour.
Cons: Higher material cost than sand and cement; requires the insulation boards and reinforcing mesh to be fitted correctly or the system will fail; not straightforward to patch a small section without visible join lines; the overall job is more complex and takes longer.
Polymer and silicone systems are worth considering when a property has poor wall insulation, when the existing render has failed across most of an elevation, or when the homeowner wants a finish that needs less frequent redecoration. The upfront cost is higher but the ongoing maintenance demand is lower.
Timber boarding - whether feather-edge, shiplap or tongue-and-groove - is a traditional choice that suits a wide range of house styles. It can be used on a whole elevation or as a feature section alongside other finishes.
Pros: Attractive natural appearance; relatively straightforward for a skilled installer; individual boards can be replaced without disturbing the whole elevation; takes paint or stain well.
Cons: Requires regular maintenance - typically a coat of preservative stain or paint every few years; if maintenance lapses, end grain and joints absorb water and rot sets in relatively quickly; needs adequate back-ventilation or moisture builds up behind the boards; cost of quality hardwood boarding has risen considerably.
Softwood timber is cheaper but needs more frequent treatment. The choice of species and finish significantly affects how long the system performs before intervention is needed.
Fibre cement cladding boards are made from a mix of cement and cellulose fibre. They come in various sizes and profiles and can be finished to resemble timber boarding, flat panels or other textures.
Pros: Much more resistant to moisture, rot and insect damage than timber; does not expand and contract as much as timber, so fixings remain secure longer; can be pre-painted at the factory; relatively low maintenance once fitted.
Cons: Heavier than timber, which affects fixing requirements and scaffolding; cannot be bent or shaped on site easily; cut edges need sealing carefully or moisture can enter the core; not all boards look convincing as a timber replacement close up; mid-range material cost.
Fibre cement is a practical middle ground for homeowners who want the look of boarding without the ongoing maintenance commitment of real timber. It works well on elevations exposed to persistent rain.
UPVC and composite boards are at the low-maintenance end of the market. They are lightweight, do not need painting and are resistant to rot and moisture.
Pros: Very low ongoing maintenance; lightweight and straightforward to fix; wide range of colours and profiles available; cost-competitive on material price.
Cons: Appearance divides opinion - some profiles look noticeably plastic; colour can fade over time and exact matches for repairs become harder to source; expands and contracts with temperature, so fixings and joints need to accommodate movement; not easily recyclable at end of life.
UPVC cladding is a practical choice for homeowners who want to spend as little time as possible on exterior maintenance. It is used widely on contemporary new-build properties and works well on extensions and outbuildings where appearance is less critical.
Before choosing a cladding material, it is worth asking a few practical questions. How exposed is the wall? What is the substrate - masonry, timber frame, or something else? Does the existing wall have a damp problem that needs addressing before anything goes over it? What is the planning position if you want to change the appearance significantly?
A new cladding system fitted over a damp wall will not cure the damp - it will trap it. That is why we always check the wall behind before recommending a system, not after the job has started.
