Exterior cladding is the outer protective layer fixed to the walls of your home. It keeps rain, wind and frost from reaching the wall structure beneath and, depending on the material, can significantly improve the appearance and thermal performance of the building. Common systems on residential properties include uPVC panels, fibre cement boards and timber boarding, all of which we fit and replace for homeowners in Littleport and the wider Ely area.
How long cladding performs well depends partly on the quality of the original installation, but also on how it is looked after once fitted. A well-installed system that is never inspected or cleaned can develop small problems that grow into expensive ones. A straightforward maintenance routine, carried out at the right intervals, will extend the life of the system and catch minor issues before they become major repairs.
All cladding materials accumulate dirt, algae and green mould over time, particularly on elevations that see less direct sunlight. Beyond appearance, algae and moss hold moisture against the surface, which accelerates degradation in some materials and can compromise sealants at joints and junctions.
A soft brush and clean water is the starting point for most systems. Upc panels generally need little more than a wash down once or twice a year with warm soapy water to remove surface grime. Avoid abrasive pads or solvents, which can scratch the surface and remove any UV-resistant coating, reducing the material's resistance to fading.
Fibre cement boards should be cleaned similarly. Avoid high-pressure washing on fibre cement at close range, as sustained pressure can erode the surface coating and allow moisture absorption into the board itself. A lower-pressure rinse from a garden hose, used from a reasonable distance, is safer.
Timber cladding needs more careful attention. A gentle wash removes surface dirt, but timber should be dried naturally and inspected for any areas where the surface treatment has worn away. Exposed timber will absorb moisture quickly, which leads to swelling, cracking and eventual rot at joints. Do not pressure-wash timber cladding at all: the water is forced into grain and joints where it sits and causes damage.
An annual inspection of your cladding, ideally in early spring after the coldest months have passed, is the single most effective maintenance habit you can adopt.
Walk around the full perimeter of your property and look for the following:
None of these checks require you to get onto scaffolding. A careful walk around the ground floor level and an inspection of the upper elevations from ground with binoculars if needed will cover most of what matters.
The sealant at junctions is what keeps water out at the points where the cladding meets other surfaces: window frames, door surrounds, corner trims and roof-to-wall details. Sealants have a finite life. Most good-quality exterior sealants will remain effective for seven to ten years, but this varies with the quality of product used originally, how well it was applied, and how much movement occurs at the joint.
When sealant cracks or pulls away, water tracks directly into the joint and behind the boards. This is one of the most common causes of moisture damage behind cladding systems, and it is almost always avoidable with timely re-sealing. If you spot a failed sealant line in your annual inspection, have it raked out and replaced before the next wet season. This is a relatively minor job when done promptly and a much more expensive one if left until water has already reached the wall behind.
If your home has timber cladding, the maintenance requirements are higher than for other systems, and the consequences of skipping them are more severe. Unprotected or poorly maintained timber will begin to absorb water, which causes the boards to swell and push joints open, then dry and contract, then crack. Over several cycles this leads to splits that allow further moisture ingress and, eventually, rot at the ends or lower edges of boards.
Pre-treated or factory-finished timber boards are better than untreated ones, but the surface treatment still needs refreshing. The interval depends on the product and the exposure of the elevation, but most systems need re-oiling, re-staining or repainting every three to five years. Check the end grain of boards in particular: this is where moisture enters most readily when the treatment wears off. Any boards where the end grain is bare or absorbing water should be treated as a priority.
Copper-based or pigmented stains generally outperform clear or lightly tinted finishes on timber in terms of longevity, because the pigment reflects UV radiation that degrades the surface. If you are maintaining or replacing the finish on timber cladding, it is worth asking your supplier or contractor which product they recommend for the specific species and installation you have.
A straightforward maintenance schedule for most cladding systems looks like this:
This level of routine maintenance is not time-consuming or expensive. It is far cheaper than the alternative, which is discovering that a failed sealant line has been admitting water behind the boards for two or three years.
Not every maintenance task needs a contractor. Cleaning, visual inspection and simple sealant replacement at accessible ground-floor level are things most homeowners can manage safely. But if your inspection reveals boards that have pulled away from fixings at height, signs of moisture reaching the wall behind the cladding, rot in timber framing or battens, or any junction where you cannot see clearly whether it is sealed, these are situations where a contractor needs to assess the extent of the problem before any work begins.
Working at height on ladders to fix or replace boards carries a real risk of injury, and disturbing boards incorrectly can make a small leak into a larger one if the membrane behind is damaged in the process.
If your cladding is due for inspection, if your maintenance has slipped and you are unsure what condition the system is in, or if you are considering new cladding for your home, call us to arrange a survey. We will give you a straight assessment of what you have and what, if anything, it needs.
