Exterior cladding problems rarely appear overnight. Most issues develop slowly, giving you time to act before water gets into the wall structure. Knowing what to look for means you can sort a problem while it is still straightforward, rather than waiting until the damage has spread deeper into the building fabric.
The most common warning sign is visible cracking or crazing across rendered surfaces. Hairline cracks let in moisture, which then freezes and expands in cold weather, widening the crack further. Once water is behind the surface layer, the render begins to pull away from the wall, a process called delamination. You may notice a hollow sound if you tap suspect areas, or see bubbling and blistering paint above the affected zone.
If you are seeing damp patches appear on internal walls, especially after heavy rain, the outer surface is very likely no longer doing its job. The moisture is travelling through the wall from outside. Efflorescence, the white powdery deposit that forms on masonry, is another indicator: it means water is moving through the brick or block and depositing salts on the surface as it dries out.
Staining around window reveals and below sills is worth taking seriously. Where cladding or render meets a window frame, the junction is one of the first places to fail. If sealant has shrunk or cracked, or if flashing is missing, water will work its way in at that point every time it rains.
Age is the straightforward answer for many properties. Older cement render becomes brittle over time and loses its ability to flex with the natural movement of the building. Even small amounts of thermal expansion and contraction, repeated over years, open up fine cracks that gradually widen.
Poor original installation is another significant cause. If render was applied in the wrong conditions, too cold, too hot, or onto a surface that was not properly prepared, it will fail prematurely. The same applies to cladding boards: if the fixing centres were wrong, or if the boards were butted too tightly without allowance for expansion, problems will follow.
Lack of maintenance accelerates failure. Blocked gutters and downpipes that allow water to run down the face of a wall will saturate the surface repeatedly. Moss and algae growth traps moisture against the wall, and roots from climbing plants can work into cracks and force them open.
Some properties need more than a repair to the outer face. If you are losing heat through solid walls, or if condensation is forming regularly on the inner face of external walls, an insulated cladding system will address both the weather protection and the thermal performance in a single installation. Solid-wall homes without cavity insulation are the most likely candidates.
The signs that suggest this level of work include persistent cold spots on external walls in winter, high heating bills relative to the size of the property, and walls that feel damp to the touch from the inside even when there is no obvious leak. A thorough inspection of the wall buildup will confirm whether insulation is appropriate.
We fit a range of cladding systems to suit different property types and budgets. The most widely used options for Norwich homeowners include:
Basic uPVC cladding to a single gable end typically costs in the region of £800 to £1,500 depending on the size and access requirements. Full-house uPVC cladding to a standard semi-detached property is usually in the range of £3,500 to £7,000. Insulated render systems cost more because the materials are more expensive and the installation is more involved: expect figures in the range of £80 to £150 per square metre for a full EWI system, all in.
These are honest ballpark figures based on typical UK costs. The only way to get an accurate number for your property is to have it inspected and measured. Call us to arrange a roof and cladding survey for your Norwich home.
We work across Norwich and into the surrounding villages.
Before you agree to any cladding work, ask the contractor to explain exactly what they will do to the wall surface before the cladding goes on. Preparation is where poor jobs cut corners. The existing render or masonry should be checked for soundness, any loose material removed, and the surface treated where necessary to prevent ongoing moisture ingress behind the new cladding.
Ask to see examples of completed work and check that the contractor understands how to handle junctions around windows, doors, soffits and eaves. These are the points where water finds a way in if the detailing is not right. A price that looks low often reflects a contractor skipping this preparation or detailing work.
If your wall has any existing damp, that problem needs to be identified and dealt with before cladding goes on. Cladding over a damp wall without fixing the cause will trap moisture and make the problem worse, not better.
