Exterior Cladding in Newmarket - Repair or Replace?

Expert Exterior Cladding
in Newmarket

What exterior cladding is and why it matters

Exterior cladding is a protective layer fixed over your external walls. It keeps wind and rain off the structure, reduces heat loss and gives the building a finished appearance. When it is working, most homeowners barely notice it. When it starts to fail, water gets in behind it, and that is when the damage to the wall behind - and sometimes to the internal structure - becomes expensive.

At Mildenhall Roofers, we fit and repair timber, composite, fibre cement and metal cladding systems on homes across Newmarket and the wider area.

The repair versus replace question

This is genuinely the first decision to get right. The wrong choice costs money in one of two ways: paying for a repair that fails within a year or two, or paying for a full replacement when a repair would have served the home for another decade. Neither outcome is good. The right answer depends on the material, the age of the installation, how widespread the damage is, and what is happening behind the boards.

When repair is the right call

Repair makes sense when the damage is genuinely isolated. A single board that has cracked, split or been mechanically damaged - by a ladder, a ball or a poorly placed aerial bracket - can almost always be replaced on its own. The key question is whether matching material is still available. Timber boards can usually be matched reasonably well. Composite profiles are trickier because ranges change, but many profiles have been in production long enough that boards can be sourced.

Repair also makes sense when the fixing system is intact and the issue is at a specific junction - a corner seal that has cracked, a window reveal that has not been properly finished, or a bottom course that has dropped slightly. These are detailing problems and they can be put right without touching the rest of the cladding.

If the substrate behind the boards is sound and dry, and the bulk of the installation is performing well, a targeted repair is the better value option. Exterior cladding in reasonable condition can be repaired for a few hundred pounds on a small area, compared to several thousand for a full re-clad.

When replacement is the right call

Full replacement becomes the right answer in several situations. The first is widespread failure - if more than roughly a third of the boards are warped, cracked, delaminating or showing surface breakdown, the rest will not be far behind. Doing a piecemeal repair on a system that is nearing the end of its life means you will be back spending money on it repeatedly.

The second situation is concealed water damage behind the boards. If water has been tracking in for a while, the battens and possibly the wall behind may have suffered. That work cannot be done properly without stripping the cladding back entirely. Fitting new boards over damaged battens and wet masonry is not a repair, it is postponing a bigger problem.

The third situation is when the original installation was poor to begin with. A badly ventilated cavity, inadequate fixings, boards fitted directly onto masonry without a cavity, or poorly sealed junctions will fail again regardless of how many times individual boards are replaced. If the system was never installed correctly, repair will not make it correct.

Material-specific guidance

Different cladding materials age differently, and that affects the repair-or-replace calculation.

• Timber cladding that has been properly painted or stained and maintained can last thirty years or more. If it has been neglected - paint peeling for several seasons, end grain left unsealed - the boards may have absorbed water and begun to rot. Rot in timber cladding rarely stays contained to one board. Check adjacent boards and any horizontal sections carefully before deciding a single-board repair is sufficient.
• Composite cladding generally holds up well, but early-generation composite products from more than fifteen years ago sometimes show surface degradation that cannot be repaired cosmetically. If the boards are chalking, fading unevenly or showing surface delamination, replacement is usually cleaner than trying to resurface them.
• Fibre cement cladding is durable and repairable if damaged mechanically. The main failure mode is at cut edges and fixings - water gets into uncoated edges and causes the board to swell and eventually crack. If you see cracking at fixing points or along cut edges, those specific boards need replacing, but the system as a whole may be fine.
• Metal cladding rarely fails in the panel itself. Problems are almost always at fixings, sealants or cut edges. These are repairable in most cases.

The inspection that makes the decision clear

The only way to answer the repair-or-replace question properly is a physical inspection. That means removing at least one or two boards to check the cavity and battens behind, not just looking at the surface from the ground. We carry out this inspection before we quote any cladding job, because the quote is meaningless otherwise.

A common problem is that a homeowner accepts a repair quote from someone who has only looked at the outside, the repair is done, and within eighteen months the same area is failing again because the batten behind was already rotten.

What a full re-clad involves and what it costs

A full exterior re-clad on a typical semi-detached house involves stripping back all existing boards, checking and replacing any damaged battens, making good the substrate, fitting new battens at the correct centres, installing the new cladding with the correct clip or fixing system, and finishing all junctions at windows, corners, soffits and the base of the wall. Scaffolding is needed for any two-storey elevation.

Exterior cladding replacement in the East of England typically costs between £80 and £150 per square metre installed, depending on the material chosen and the complexity of the detailing. A full semi-detached house re-clad on the front and sides will usually fall in the range of £4,000 to £10,000 depending on size and material. These figures should be used as a planning guide only - a quoted price needs to be based on a site visit.

Getting the decision right the first time

If you are weighing up repair against replacement on your Newmarket home, call us to arrange a cladding survey. We will check what is behind the boards, give you an honest view of how much usable life the current system has, and quote for both options where repair is genuinely viable so you can make an informed choice.
