What Exterior Cladding Does for Your Building

Cladding is the outer skin of a building. It keeps rain and wind off the structural walls, improves thermal performance, and determines how a property looks from the street. When it fails, water finds its way in behind it and the real damage - to insulation, timber framing, and interior walls - builds up quietly over months before you see it indoors.

We install and replace exterior cladding on homes and commercial buildings across Newmarket and the wider area. Whether the original cladding has failed or the building simply needs a modern, lower-maintenance finish, we'll recommend the right system and fit it properly.

The Warning Signs You Should Not Ignore

Most cladding problems start small and visible. Catching them at that stage is far cheaper than waiting until water has penetrated the wall structure. Walk around the outside of your property and look for these signs.

• Cracking or crumbling render. Hairline cracks in rendered cladding let water in every time it rains. Frost then expands the water inside the crack, breaking the render further. What starts as a hairline becomes a gap within one or two winters.
• Bubbling or blistering paint or coating. This usually means moisture is trapped between the cladding surface and the layer beneath it. The coating has lost its bond and is no longer keeping water out.
• Soft, spongy or warped timber boards. Timber cladding that has not been kept sealed will soak up rain. Once the fibres swell repeatedly and dry out, boards warp, split and rot from the back face first, so the damage is often worse than it looks from the front.
• Staining or dark streaking. Persistent damp staining down the face of cladding, especially below joints or window sills, points to failed flashings, missing or cracked sealant, or boards that have shrunk away from each other and opened up gaps.
• Loose or missing fixings. Boards that flex in the wind or that have started to pull away at the edges are a straightforward fix if caught early. Left alone, the movement works water behind the board on every wet and windy day.
• Damp patches on internal walls. By the time moisture is visible inside, it has usually been travelling through the wall for some time. This is a late sign, not an early one.
• Mould or moss growth on the cladding surface. Persistent organic growth means the surface is retaining moisture rather than shedding it. This indicates the original finish or surface treatment has broken down.

What Causes Exterior Cladding to Fail

Understanding why cladding fails helps you ask better questions when getting work done and avoid repeating the same problems with a new system.

Poor original installation is behind a large proportion of premature failures. Boards fitted without adequate ventilation behind them trap moisture between the cladding and the wall. Render applied over an unsuitable substrate, or without the correct mesh and bonding coat, will crack within a few years regardless of product quality.

Neglected maintenance shortens the life of any system. Timber cladding needs re-sealing or repainting on a regular cycle. Render and composite materials need periodic inspection of joints and sealant lines. Once the protective surface layer breaks down, deterioration accelerates.

Failed fixings and movement affect older properties where original screws or nails have corroded. As fixings rust, they stain the boards and lose their grip, letting boards shift with thermal expansion. Over time, joints open up and gaps appear.

Inadequate or missing flashings at window heads, sills, abutments and roof lines are a very common cause of water ingress behind cladding. Water that cannot get in through the face of a board will find a way in at the junction between cladding and another element if the flashing is missing, poorly fitted or has cracked over time.

Age and UV degradation affect every material eventually. Pigments fade and surface coatings break down. Some render systems have a practical lifespan of fifteen to twenty years before recoating or replacement becomes necessary.

What a Proper Survey Covers

Before any work is specified or priced, the cladding and the wall behind it need to be assessed properly. A good survey checks not just the visible face of the cladding but the fixings, the ventilation gap (if there is one), the condition of any breather membrane behind the boards, the flashings at every junction, and the substrate the cladding is fixed to.

If the survey reveals that the wall behind is damp or that insulation has been saturated, that needs to be factored into the scope of work. Fitting new cladding over a wet wall will trap the moisture and cause the same problems to repeat.

When Repair Is Enough and When You Need Full Replacement

Not every cladding problem requires a full strip and re-clad. Localised cracking in render, individual failed boards, or isolated joint failures can often be repaired in a targeted way. The test is whether the failure is local or systematic. If boards are failing across the whole elevation, if the breather membrane behind is degraded, or if fixings are corroding right across the wall, partial repairs buy only a short amount of time before the next failure.

Full replacement costs more upfront but means the whole system - fixings, battens, membrane, boards or panels and finishes - is new and performing as intended. It also gives you the chance to upgrade the insulation layer behind the cladding at the same time, which can have a measurable effect on heating costs.

Cladding Options for Newmarket Properties

The right material depends on the building type, the budget, and how much ongoing maintenance you are prepared to do. Common systems include treated and painted timber, composite boards (wood fibre and polymer), fibre cement panels, and through-colour render systems. Each has genuine advantages and trade-offs in terms of cost, appearance and maintenance requirement. We'll explain the options that suit your building and give you honest advice on what each one involves over time.

Commercial Cladding Work

We work on commercial properties as well as homes. Offices, warehouses, light industrial units, and public-facing buildings all require cladding that performs well and looks presentable.
