What Exterior Cladding Does for Your Home

Exterior cladding is fitted over the existing outer surface of your property - whether that's bare masonry, pebbledash, painted render or weathered timber boarding. It creates a new, protective skin that keeps moisture out, improves the look of the building and can add a layer of insulation depending on the system chosen.

For homeowners in Mattishall and the surrounding villages, cladding is often the most practical answer when a wall has deteriorated past the point where patching and repainting makes sense. Instead of repeatedly treating a failing surface, you cover it with something more durable and lower-maintenance.

We fit cladding systems suited to Norfolk homes of all types - detached houses, bungalows, semi-detached properties and outbuildings. The same approach applies whether you want to re-clad the whole facade or just one gable end that takes the worst of the weather.

The Warning Signs That Tell You It's Time to Act

This is the angle most homeowners need help with. A failing outer wall rarely announces itself dramatically. More often, it gives you a series of quieter signals over months or years - and those signals are easy to dismiss until the damage becomes expensive.

Here are the warning signs worth taking seriously:

• Damp patches on internal walls or ceilings. If moisture is getting through the outer leaf of the wall, you'll eventually see it inside. Cold, slightly discoloured patches on plaster, especially after a wet spell, are a strong indicator that the wall's weather-resistance has broken down.
• Crumbling or spalling masonry. When the face of a brick or block breaks away, it's usually because water has got in, frozen and expanded inside the material. Once this starts, it accelerates. Repointing alone won't fix a brick that has begun to spall.
• Cracked or bubbling render. Render that has cracked allows water behind it. Once water sits between the render and the wall, frost pushes the render away from the masonry. Patches of render that sound hollow when tapped have already lost adhesion.
• Persistent damp smell in rooms that back onto an outside wall. This is one of the first signs of penetrating damp, even before you see visible moisture on the plaster.
• Paint or external coating that peels or flakes repeatedly. If you have re-painted the same wall two or three times and the paint keeps failing within a year or two, the wall surface itself is the problem, not the paint. Water is pushing out from within.
• Efflorescence - white salt deposits on the wall face. These white, chalky streaks form when moisture moves through masonry and carries dissolved salts to the surface. The staining itself is not the problem; it is evidence that water is moving through the wall.
• Warped or split timber cladding. If your property already has timber boards fitted, boards that have cupped, split or pulled away from fixings are letting water in behind them. Localised repair is sometimes possible, but widespread movement usually means the whole run needs replacing.

What Causes These Problems in the First Place

Understanding what causes wall deterioration helps you make a more informed decision about the remedy. The root causes fall into a handful of categories.

Age of the original finish. Pebbledash, sand and cement render, and painted masonry all have a working life. A render coat that was applied twenty or thirty years ago may simply have reached the end of what it can do. The material dries out, loses flexibility and begins to crack under normal thermal movement.

Thermal movement. Walls expand and contract slightly with changes in temperature. Over many years, a rigid finish that cannot flex with the wall will develop hairline cracks at corners, around window reveals and along horizontal lines. Those cracks widen gradually and become water entry points.

Poor original application. Render that was mixed too wet, applied to a surface that wasn't prepared properly, or put on in too thick a single coat is prone to early failure. A common problem is render that was applied directly over a very smooth surface without adequate keying, so it never fully bonds.

Lack of maintenance. Gutters that have overflowed for years down a wall, downpipes that discharge at the wall base rather than into a drain, and missing or cracked sealant around window frames all allow far more water into the wall than normal weather exposure would cause on its own.

Rising damp at the base. Where ground levels have built up against the wall - soil or paving sitting above the damp-proof course - moisture can travel up through the masonry. This shows as damage concentrated in the lower section of the wall.

Why Cladding Is Often the Right Fix

When a wall has reached the point where the original finish has failed or is failing in multiple places, you have a choice: strip and re-render, or clad over the existing surface. Stripping and re-rendering is disruptive, messy and still leaves you with a surface that will need maintenance in another twenty years. Cladding, by contrast, removes the maintenance burden for a much longer period and can dramatically improve the appearance of the property at the same time.

Cladding is particularly suitable where:

• The existing render or masonry is structurally sound but cosmetically poor or weather-worn
• The property has had repeated render failures and the homeowner wants a long-term solution
• The wall is visible from the front or side and appearance matters as well as performance
• The property is occupied and a minimum of disruption is needed during installation

It is not always the right answer. If there is active structural movement in the wall, or if rising damp or serious water ingress has caused damage to the inner leaf, that problem needs addressing before any new surface is fitted. Fitting cladding over a genuinely wet wall traps moisture and makes the underlying problem worse. A proper inspection of the wall should happen before any product is chosen.

The Cladding Systems We Fit

The main options for Norfolk properties are uPVC weatherboard, timber boarding and aluminium composite systems. Each has its own strengths depending on the property type and what the homeowner is trying to achieve.

uPVC weatherboard is the most widely fitted system on domestic properties. It is low maintenance, does not need painting and is resistant to sustained damp exposure. Boards are available in a range of profiles and colours and can be matched to the existing window and door frames. Typical installed costs for uPVC cladding run from around £80 to £130 per square metre depending on the profile, preparation needed and access requirements.

Timber cladding suits properties where the look of natural materials matters - rural settings, barn conversions and period homes. Properly treated softwood or hardwood boards can last well, but they do require periodic maintenance: oiling or staining every few years depending on exposure. Untreated or poorly maintained timber will deteriorate, which is why this option needs honest consideration before you choose it.

Aluminium composite panels are more often seen on commercial or mixed-use buildings but can work on contemporary residential properties. They are extremely durable and the factory-applied finishes hold their colour for many years without repainting. They are typically more expensive than uPVC but the maintenance requirement over the life of the installation is very low.

What the Installation Process Involves

Regardless of the material chosen, cladding installation follows a similar sequence. The existing wall surface is inspected and any loose render, damaged pointing or active damp issues are dealt with before work starts. A timber or aluminium frame - called a batten system or carrier frame - is fixed to the wall. This creates a ventilated gap between the wall and the cladding boards, which allows any moisture that does get behind the cladding to escape rather than sit against the wall. The boards are then fixed to the frame, working from the bottom up, with joints sealed and external corners finished with purpose-made trims.

Window and door reveals need careful detailing. This is where poor cladding installations fail - water tracks along the top of a window frame, finds a gap at the junction between the cladding and the window surround, and gets behind the boards. Good installation means fitting proper sill extensions, sealing every joint and checking that water sheds away from all openings.

Scaffolding is usually needed for anything above ground-floor level. Access costs should be included in any quote you receive; be cautious of any price that doesn't make clear whether access is included.

What to Ask Before You Agree to Any Work

Before you commit to a cladding installation, it is worth asking these questions of any contractor:

• Will the existing wall surface be inspected before any product is specified? You need to know the wall is dry and sound before the cladding goes on.
• Is a ventilated cavity included in the specification? Boards fixed directly to the wall without a ventilated gap behind them are more prone to moisture problems.
• How will window and door reveals be dealt with? Ask to see examples of completed work at these junctions.
• Is scaffolding included in the price, or is it additional?
• What surface preparation is included - will any loose render or damaged pointing be cut out and made good before the frame is fixed?

A quote that answers all of these points clearly is a good sign that the contractor has thought through the job properly rather than just putting a number on square metreage.

Typical Costs for Exterior Cladding

Exterior cladding costs depend on the material, the condition of the existing wall, access requirements and the level of preparation needed. uPVC systems usually sit at the lower end of the price scale; timber and aluminium composite systems tend to sit higher. A full re-clad of the front and side elevations of an average detached house might run from £4,000 to £10,000 or more depending on size and specification.

These are realistic typical ranges. Any firm quote will depend on a proper look at the property. Be cautious of any price given without a site visit - the condition of the existing wall and the access situation both affect the cost significantly.
