Cladding and IPS Panel Repairs in London

Cladding and IPS panel repair in London typically costs £80 to £450 depending on whether you need a resealed joint, a single replacement bathroom wall panel, or a section of IPS boxing rebuilt around pipework. Most jobs are a single two to three hour visit. The reason it matters more than it looks: water getting behind a cracked panel or a failed inspection hatch is one of the most common causes of hidden rot, mould and ruined plasterboard we find behind bathroom walls across London.

What an IPS Panel Is, and Why Your Bathroom Has One

IPS stands for Inspection Panel System. It is the boxing, usually PVC or laminate-faced MDF, built around bath and shower pipework so the plumbing is hidden but still reachable through a hinged or screw-fixed access hatch. You will find IPS boxing in almost every flat built or refitted in London since the 1990s, and it is standard in blocks with communal risers in Canary Wharf, in student and serviced accommodation, and in the rebuilt bathrooms of period conversions in Chelsea and Kensington where original pipe runs have been boxed in rather than chased into walls.

Cladding, in the context of this page, covers two separate things. First, bathroom wall cladding: the full PVC or laminate wet wall panels (brands such as Multipanel and Mermaid are common) used instead of tiles in showers and around baths. Second, exterior cladding: weatherboard, composite board, or render-effect panels fitted to extensions, loft conversions and the odd mansion block balcony, which we see fail from UV, movement and water ingress rather than impact.

Cladding and IPS Panel Repair Cost in London

Prices below are typical ranges for straightforward domestic jobs in inner and outer London. They assume ground or first floor access with no scaffolding. Confirm an exact figure once we've seen the panel and the damage, because the price swings a lot depending on whether a replacement panel has to be colour matched or sourced to order.

Two things change the price more than anything else. One is access: upper floor exterior cladding in tall terraces around Hampstead or Highgate can need a tower or scaffold, which adds separately to the quote. The other is matching: if a wet room panel system has been discontinued, which happens a lot with older Multipanel and Mermaid ranges, we may have to re-panel a whole wall rather than one sheet to avoid a visible seam. For a general sense of day-rate handyman pricing before you commit to a specific job, see our handyman prices in London guide.

Common Cladding and IPS Panel Problems We Fix

The jobs that come up most often, roughly in order of frequency:

• Cracked or split PVC wall panels around bath taps or shower mixers, usually from someone leaning on the panel or from the panel drying out and shrinking at a cut edge.
• Failed sealant at panel joints, which lets water track behind the panel into the timber frame or plasterboard, usually not noticed until the panel starts to bow.
• Broken or seized IPS access hatches, where the magnetic catch, hinge or push-fit clip has given up, often after years of being painted over or screwed shut by a previous tradesperson.
• Discoloured or yellowing panels near extractor fans and heat sources, which is a surface issue and is usually a replacement job, not a repair.
• Mould at the panel-to-bath or panel-to-floor junction, which is a sealant and ventilation issue nine times out of ten, not a panel fault.
• Loose or warped exterior cladding boards after wind or prolonged rain, common on rear extensions in Barnes, Dulwich and Putney where composite boarding was fitted at low cost during a loft or kitchen extension.
• Cladding pulling away from fixings around window reveals and soffits, which often points to a fixing that was never adequate for the board weight, not a one-off storm event.

The expensive mistake: leaving a cracked panel or a failed seal around an IPS hatch "for now" because it looks cosmetic. Water behind a bathroom panel doesn't evaporate the way it does on a tiled wall. It sits against timber and plasterboard in the dark, and by the time you see a stain or smell damp, the frame behind the panel is often already soft. A £60 to £150 reseal or panel swap, caught early, regularly prevents a £2,000 to £4,000 bathroom strip-out later. If a panel has been cracked for more than a few weeks, assume there's moisture behind it and get it checked rather than just resealed.

Repair or Replace: How We Decide

We repair where the damage is localised and the panel system is still available or easy to match. That usually means a straight crack, a loose joint, or a hatch mechanism fault. We recommend replacement when the panel has gone soft, when there's visible delamination (the laminate skin lifting from the backing board), when the colour or finish no longer exists to match, or when we lift the panel and find the timber frame behind it has already taken on moisture. In that last case, the honest answer is that the panel was never the real problem, and fixing it without addressing the frame just hides the issue again for another year or two.

For exterior cladding, the same logic applies but with weather thrown in. A single warped board on a south-facing extension wall in Clapham or Battersea can usually be swapped without touching its neighbours. But if two or three boards near each other have failed, it's worth checking the breather membrane and fixings behind the cladding rather than just replacing boards one at a time, because that pattern usually points to a water ingress issue, not board quality.

What Happens During a Repair Visit

A typical IPS or bathroom cladding call-out runs like this: we assess the panel and the hatch mechanism, check for moisture behind the panel with a damp meter where there's any sign of staining or softness, and quote on the spot for straightforward jobs. If a replacement panel needs sourcing to match an existing system, we'll confirm the panel reference where possible and come back with a firm price before ordering anything. Sealant work is done with a sanitary-grade silicone rated for wet areas, not a general-purpose sealant, because standard caulk fails faster around baths and showers.

Where the job overlaps with plumbing, for example an IPS hatch that needs widening to reach an isolation valve, we coordinate with our plumbing services team rather than cutting into boxing blind. Where the frame behind a panel needs rebuilding in timber, that's handled as a carpentry job first, panel second. If the bathroom finish needs touching up afterwards around the panel edges, that's a short painting and decorating visit, not a separate call-out.

Areas We Cover

We handle cladding and IPS panel repairs across London, with particularly frequent call-outs in Chelsea, Kensington and Wimbledon, where older bathroom refits and period conversions mean a lot of boxed-in pipework that's now fifteen to twenty years old and due attention. We also work regularly in Knightsbridge, Mayfair, Belgravia, Notting Hill, Holland Park, Fulham, South Kensington, Marylebone, St John's Wood, Richmond, Kew, Hampstead, Highgate, Primrose Hill, Islington, Battersea, Clapham, Putney, Barnes, Dulwich and Canary Wharf. If you're outside these areas, ask, because coverage extends further and we'll tell you straight if a particular postcode is a stretch for same-week availability.

Questions to Ask Before You Book a Repair

Before you commit to any quote, worth asking:

• Will the panel be checked for moisture behind it, or just resealed on top?
• Is the replacement panel an exact match, or the nearest available? Ask to see a sample before the day of the job.
• What sealant is being used, and is it rated for continuous wet exposure?
• If exterior cladding, is access (tower, ladder, scaffold) included in the quote or billed separately?
• If the IPS boxing has to come off entirely, is there an allowance for finding something unexpected behind it (rot, old leak, poor original fixing)?

Any handyman who can't answer the moisture question clearly is probably planning to reseal and move on, which is fine for a cosmetic crack but not for anything that's been damaged more than a few weeks.

FAQ

What is an IPS panel?

IPS stands for Inspection Panel System. It's the boxing, usually PVC or laminate-faced board, built around bath and shower pipework in a bathroom, with a hinged or removable hatch so a plumber can reach isolation valves or traps without breaking into the wall. Almost every London flat with a refitted or newer bathroom has one, even if the homeowner has never noticed or opened it.

Can you repair a cracked bathroom cladding panel, or does it need replacing?

A small, recent crack with no softness or staining around it can usually be repaired by sealing and, if needed, patching. A crack that's been there more than a few weeks, or that shows any softness, discolouration or smell nearby, usually means moisture has got behind the panel, and the panel should be replaced so the frame behind it can be checked.

How much does it cost to replace a shower wall panel in London?

A single replacement PVC or laminate shower wall panel typically costs £120 to £220 including labour, for a straightforward swap where the colour and size match what's already there. Costs rise if the original panel system has been discontinued and a wider re-panel is needed to avoid a visible mismatch, or if the frame behind the panel also needs attention.

Is cladding or IPS panel repair covered by home insurance?

It depends on the cause and your policy. Sudden, accidental damage (a panel cracked by an impact) is sometimes covered; gradual damage from a slow leak or poor original sealant usually isn't, because most policies exclude wear, maintenance and gradual water ingress. Check your specific policy wording and speak to your insurer before assuming a repair will be covered.

How long does an IPS panel repair take?

Most single-panel or hatch repairs take 45 minutes to two hours. A full IPS boxing rebuild, including new timber frame and panel, typically takes half a day. Exterior cladding jobs vary more with weather and access, from a couple of hours for one ground floor panel to a full day if scaffolding or a tower is needed.

Can you match existing cladding panels, or will there be a visible seam?

Often yes, if the exact panel reference or a close colour match is still available, which we'll check before ordering anything. Where a panel system has been discontinued, which is common with wet wall boards more than ten years old, the honest option is usually to re-panel the full wall rather than leave a mismatched seam, and we'll flag that cost difference before starting.

Do I need a plumber or a handyman for IPS panel repairs?

For the panel, hatch or sealant itself, a handyman experienced in bathroom fit-outs is the right call. If the job involves accessing or altering pipework behind the panel, such as replacing an isolation valve, that part needs a plumber. We coordinate both under one visit where needed, rather than sending you to book two separate trades for one job.

What causes IPS panels and bathroom cladding to crack or discolour in the first place?

Most commonly: physical impact (leaning or sitting weight on a panel edge), heat from a nearby extractor or towel rail causing the laminate to lift, prolonged damp behind the panel from a failed seal, or simple age, since most PVC and laminate panel systems are rated for a working life of roughly ten to fifteen years before the finish starts to degrade.
