What Exterior Cladding Is For

Exterior cladding is a system of boards or panels fixed to the outside face of a wall, designed to protect the structure beneath from rain, frost and wind while improving the appearance of the building. It is not simply a cosmetic product - done properly, it forms a weather-resistant skin that can extend the life of a wall significantly and reduce the need for repeated repainting or repointing.

We fit cladding to homes in Harleston and the surrounding area as part of our wider exterior work. The choice of material is the decision that shapes everything else: cost, maintenance, appearance and longevity all vary considerably between the main options available.

The Main Cladding Materials

There are three materials that are genuinely practical for most domestic properties: timber, uPVC and composite boards. Each one suits a different set of circumstances, and no single option is best for everyone.

Timber Cladding

Timber is the most traditional cladding material and, when specified and maintained correctly, it can be very long-lasting. Feather-edge boarding, shiplap and tongue-and-groove profiles are all common on domestic properties. Hardwoods such as oak and western red cedar are more durable and more resistant to moisture than softwoods, though they cost more to buy and work with.

Pros:

• Natural appearance that suits older or rural properties very well
• Can be stained or painted in a wide range of colours
• Easier to repair in sections than uPVC or composite - damaged boards can be replaced individually
• Good thermal performance when installed over insulation

Cons:

• Requires regular maintenance - staining or painting every few years is non-negotiable on untreated or softwood boards
• Vulnerable to rot if water is allowed behind the boards or if end grain is left unsealed
• Softwood is cheaper upfront but costs more in maintenance over a decade than harder-wearing alternatives
• Movement is inevitable as timber expands and contracts with temperature and moisture - fixings and joints must allow for this

For homes in Harleston where appearance is the priority and the owner is willing to commit to upkeep, timber is a strong choice. For owners who want to reduce ongoing maintenance, the alternatives below are more practical.

uPVC Cladding

uPVC (unplasticised polyvinyl chloride) cladding is the most widely fitted type on domestic properties across the UK. It comes in a range of profiles - hollow-back boards, solid boards and various lap styles - and is available in a growing range of colours, including woodgrain foil finishes that mimic the look of timber from a short distance.

Pros:

• Very low maintenance - washing down with a hose or soft brush once or twice a year is typically all it needs
• Does not rot, rust or require painting
• Significantly cheaper upfront than composite and usually cheaper than good-quality hardwood timber
• Widely available and quick to install

Cons:

• Hollow-back profiles can sound thin when knocked or in heavy rain - solid boards perform better acoustically
• Colour choices are more limited than timber, and foil finishes can fade or peel over time, particularly on south-facing elevations with high sun exposure
• Not easily repairable at board level in the same way timber is - damaged sections often require a longer run of boards to be lifted
• Can look obviously plastic at close range, which some homeowners and planners dislike in certain settings
• Thermal expansion is significant in uPVC; boards must be fixed with this in mind or joints will open and close visibly with temperature changes

uPVC is the most sensible choice for most homeowners in Harleston who want a low-maintenance result at a reasonable cost. It performs well and, properly fitted, should last for many years without significant attention.

Composite Cladding

Composite cladding boards are made from a mixture of wood fibre and plastic (usually polyethylene), pressed or extruded into boards that look considerably closer to real timber than uPVC does. The category has expanded rapidly in the past decade and quality varies considerably between manufacturers and grades.

Pros:

• Much more realistic timber appearance than uPVC, including texture and depth of colour
• Very low maintenance compared to real timber - generally needs only an occasional wash
• Resistant to rot, insects and moisture when correctly installed with appropriate fixings and ventilation
• More dimensionally stable than solid timber - less movement with temperature and humidity changes
• Better scratch and impact resistance than uPVC in most grades

Cons:

• Significantly more expensive than uPVC - good composite cladding costs noticeably more per square metre for materials alone
• Cheaper composite boards can absorb moisture if the wood fibre content is high and the sealing is poor - end caps and correct detailing are critical
• Heavier than uPVC, which affects the fixing and batten specification required
• Not all products are equal; it is worth asking what the manufacturer states about performance and expected lifespan before committing

Composite is the premium practical option. For homeowners in Harleston who want the look of timber without the maintenance, and who are prepared to spend more upfront, it is worth serious consideration. Typical installed costs for composite cladding in the UK currently run from around £80 to £150 or more per square metre depending on profile and grade, compared to roughly £40 to £80 per square metre for uPVC installed.

What the Installation Requires

All three materials need a proper fixing framework. Cladding is not fixed directly to the wall face - it is fixed to a batten system that sits proud of the wall, creating a ventilated cavity behind the boards. That cavity is important. It allows any moisture that gets past the face of the cladding to drain and dry out rather than sitting against the wall structure. Without it, even good-quality cladding will eventually cause problems.

The battens must be fixed securely into the masonry or timber frame of the building, not just into render. On older properties, this sometimes means the render needs to be cut back or stripped in sections to get fixings into sound material. The bottom of the installation needs a starter strip and a pest mesh or drainage channel to keep insects and debris out of the cavity while allowing airflow and drainage.

Window and door reveals, soffits, corners and pipe penetrations all need to be finished carefully. These are the details where water will find a way in if the workmanship is not thorough. A clean-looking cladding job that has poorly sealed reveals will let in more water than the original wall did.

What to Ask Before You Agree to Any Quote

When getting quotes for exterior cladding in Harleston, these are the questions worth putting to every contractor:

• What preparation do you plan to do to the existing wall before battening out?
• What batten size and fixing centres are you specifying, and are they appropriate for the board weight?
• How will you handle the reveals around windows and doors?
• Is there a ventilated cavity behind the cladding, and how will the bottom edge be finished?
• Can you show me the specific product you are proposing, including the manufacturer's installation guidance?

A contractor who can answer these questions specifically and consistently is demonstrating that they understand what a proper installation involves. If the answers are vague, that is worth noting before you sign anything.
