What exterior cladding actually does

Exterior cladding is a protective layer fixed over your building's outer walls. It keeps wind-driven rain from saturating the masonry or render beneath, improves thermal performance, and gives the facade a uniform, finished look. Done properly, it adds decades of weather protection to a home without the ongoing maintenance that bare render demands.

We fit cladding systems to houses, bungalows, garages and outbuildings across Tuddenham and the surrounding area, working out of our base in nearby Mildenhall.

The warning signs that your walls need attention

Most homeowners notice the cosmetic problems first - staining, flaking paint, or green algae creeping up the lower courses. These are real warning signs, but they are rarely the whole story. By the time a wall looks bad on the outside, moisture has usually been working its way in for some time.

Below are the signs that tell us a wall needs cladding or has an existing cladding system that is failing:

• Damp patches inside - a persistent damp patch on an internal wall, especially after heavy rain, suggests the outer skin is no longer keeping water out.
• Blown or bubbling render - render that has separated from the masonry behind it lets water pool in the gap and accelerates the problem.
• Cracked or spalling brickwork - once water gets into brick and freezes overnight, it expands and breaks the face off. Once spalling starts, it does not stop on its own.
• Rotting timber boards or sills - if the property already has timber cladding and the boards feel soft underfoot or at the base, the moisture barrier beneath has probably failed.
• Paint that will not stay on - if you have repainted the same wall twice in five years and it still peels, moisture is pushing through from behind. Painting over it again is wasted money.
• Cold spots in winter - walls that feel noticeably colder on the inside, or rooms that cost more to heat than they should, often have inadequate or missing insulation in the wall build-up.
• Gaps around window and door frames - where old cladding has shrunk or shifted, gaps open up around frames and let water channel straight to the timber lintels behind.

What causes cladding to fail?

Poor installation is the single most common cause of premature failure. Cladding relies on a correctly detailed drainage cavity behind the boards, proper flashings at every junction, and the right fixings for the material in question. When any of these are wrong, water finds its way in and has nowhere to escape.

Material choice matters too. Untreated or poorly treated timber will absorb moisture and split. Cheap composite boards can delaminate at the edges when they are cut and the cut face is left unsealed. Fibre cement is durable but brittle if the fixing centres are too wide and it flexes under wind load.

Age plays a part on older properties where cladding was fixed with the technology available at the time. Flashings that were lead-dressed rather than purpose-formed tend to lift at the edges as the lead fatigues. Silicone sealants that were used as a shortcut instead of proper flashings harden, crack and fail entirely within ten years.

Cladding materials - what is available and what each one suits

We fit four main types of exterior cladding system, and we will always talk through which suits your property before starting work.

Timber cladding is the most traditional option and suits both modern and period homes. Featheredge, shiplap and square-edge boards all give different appearances. Timber needs periodic treating or painting but is repairable board by board if damage occurs. It is not suited to areas with very poor drainage or overhanging vegetation that keeps it permanently damp.

Composite cladding is made from a blend of wood fibre and plastic, pressed into boards or panels. It does not rot or need painting, and the colour is stable for many years. It is heavier than timber and needs adequate fixing noggins behind it. The surface can look slightly uniform compared to real timber, which matters on some properties.

Fibre cement cladding is produced from cement, sand and cellulose fibre. It is non-combustible, which makes it a practical choice where building regulations require a fire-rated external wall system. It is factory primed and can be finished in almost any colour. It is harder and more rigid than timber or composite, which makes cutting and detailing slower on site.

Metal cladding - typically aluminium or steel with a polyester powder coat finish - is used on contemporary homes, extensions and outbuildings. It is extremely durable, fully weatherproof and low maintenance. Standing seam and cassette profiles give a very clean, architectural look. It is the most expensive option but requires very little attention once installed.

What to ask before any cladding work starts

Before you commit to cladding your home, there are a few questions worth getting clear answers to. Ask whether a drainage cavity is included in the specification - cladding fixed flat against the wall with no air gap behind it traps moisture and defeats the purpose. Ask how the junctions at windows, doors, eaves and ground level will be detailed - the flashings at these points are where most failures begin. Ask whether the existing wall surface needs preparation and what that involves. And ask specifically what fixings are being used and whether they are appropriate for the material.
