If exterior cladding on your North Walsham home has failed or been damaged, there are practical steps you can take to protect your property while the repair or replacement is arranged.
Exterior cladding acts as a weatherproof skin over your home's walls. When it is working correctly, rain runs off the surface, the cavity behind it ventilates freely, and the wall structure stays dry. When a section fails - through rot, impact damage, cracked boards, or failed junctions - rain and wind start getting behind the system. From that point, the damage to the wall and substrate underneath gets worse with every wet day.
At Cromer Roofers we fit and repair timber, composite, and fibre cement cladding across North Norfolk, including North Walsham. We know that the time between a failure becoming obvious and the repair being done is not always short - materials need ordering, scaffolding needs scheduling, and surveys take time. This page is about what you can and cannot do in the meantime to prevent a manageable problem from becoming a serious one.
Before you do anything, it helps to understand the extent of the problem. From ground level - and only from ground level - take a careful look at the affected section. Note what you can see:
A single cracked or bowed board is a contained problem. A section where multiple boards have failed or where the junction sealant has gone on a window above the damaged area is a more urgent situation because water is actively being directed into the wall. Knowing which category you are in helps you communicate clearly with the contractor and helps you prioritise the interim steps below.
There is a short list of genuinely helpful things a homeowner can do while waiting for a professional, and it is worth being specific about each of them.
Seal a cracked junction from ground level. If a window or door reveal has cracked sealant at the junction between the frame and the cladding, and you can reach it safely from ground level, applying exterior-grade mastic sealant is a sensible temporary measure. Clean the crack out with a stiff brush first, remove any loose old sealant, and press new mastic firmly into the joint. This is not a permanent repair but it reduces water ingress at that specific point while you wait. Use a mastic rated for exterior use on the relevant material - the label will specify this.
Clear debris from around the base. Leaves, soil, and plant material piled against the bottom boards trap moisture. Clear these away and make sure there is a clear gap between any garden beds or planting and the base of the cladding. This costs nothing and removes one source of ongoing moisture.
Direct water away from the damaged section. If a gutter or downpipe directly above the affected section is blocked or broken and is discharging water onto the wall, that is a separate problem making the cladding situation worse. Clearing the gutter blockage from the ground - with a telescopic gutter-cleaning tool if needed - reduces the volume of water hitting the damaged section.
Monitor internally for signs of damp. Check the internal wall surface that corresponds to the damaged elevation. Cold patches, a damp smell, or visible moisture on plaster or paintwork tell you the water has already reached the wall structure. Photograph these signs and report them to the contractor - it changes the scope of the repair.
Some of the most common DIY attempts on failed cladding make the eventual professional repair harder, more expensive, or both. These are the ones to avoid.
Do not attempt to refix loose boards yourself. A board that has bowed or pulled away from the wall has done so because the fixing has failed or the board has swollen and distorted. Screwing it back flat without investigating what is behind it can split the board further, damage the breather membrane, and push moisture further into the cavity. The underlying cause does not go away just because the board is flat again.
Do not use a pressure washer on the damaged section. It is tempting to wash away the algae and dirt to get a clearer look at the damage. On compromised cladding, a pressure washer drives water directly into any crack, gap, or loose fixing hole with far more force than rain ever would. On timber boards in particular, it also raises the grain and forces water into the wood structure.
Do not apply exterior filler to large cracks in timber boards. Small chips on fibre cement can be filled as a temporary measure. On timber, a crack that is large enough to be visible is usually a sign that the board has split along the grain - which means it has absorbed enough moisture to distort. Filling it traps moisture inside the crack and accelerates rot rather than preventing it.
Do not work at height on cladding. Any section of failed cladding above ground-floor level is not safe to approach from a domestic ladder. Cladding boards are not structural and cannot bear weight; a ladder placed against them or leant on them can dislodge adjacent boards and create additional damage. Scaffolding or a proper access platform is the only safe way to work on cladding above ground level, and that is what a professional contractor will arrive with.
Do not cover the wall with polythene sheeting or plastic membrane if you can avoid it. This is a common instinct when a section of cladding is visibly open to the weather. The problem is that an airtight cover traps any moisture already in the wall and prevents it from drying out. If you need temporary weather protection, a breathable cover secured at the top and left open at the bottom is better than a sealed one. Better still, describe the situation to the contractor and ask how urgently they can attend.
The more clearly you can describe the situation when you call, the more accurately the contractor can advise you and prioritise the visit. Useful information to have ready includes:
Photographs taken from ground level are genuinely helpful and mean the contractor arrives better prepared, with a clearer idea of access requirements and materials needed.
Once the contractor arrives, the first step is always to take off at least some of the damaged boards to assess the substrate behind. This is not optional - it is the only way to know whether the damage is limited to the boards or has reached the wall. Any repair that does not include this step is incomplete.
If the substrate is sound, new boards are cut and fitted with correctly rated fixings, the breather membrane is checked or replaced, and junctions are resealed. If the substrate has taken water damage, that needs to be treated or replaced before new cladding goes back on. Putting new boards over a wet or rotted substrate just restarts the same problem.
If your cladding has failed and you are not sure how urgent the situation is, call us. We cover North Walsham and the surrounding area and can talk you through what you are seeing and how quickly it needs to be dealt with. Getting the right advice early is the simplest way to keep a straightforward repair from becoming a much larger job.
