Remedial sealant for homes and businesses in South Mundham
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. We’re often asked to deal with smears and lumps from a botched reseal and sealant peeling off a dusty or damp surface, on leaking tray & enclosure joints, expansion joints and mouldy bath & shower sealant.
Homes around South Mundham are mostly houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. Sealant and grout wear out here just as they do anywhere: old material cut out, joints cleaned and a fresh finish laid.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What happens if it’s left?
Repeat failures have a cause. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Around South Mundham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.
Why book with us
- Anti-fungal silicone where joints get wet
- A choice of colours where the product allows
- Every job guaranteed for a year
- Approved under the ARBOMaster scheme
What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere like South Mundham needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property
- Move anything stored near the joints

Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
What if the leak is not the sealant?
Then we explain what we’ve found. You may need a plumber or bathroom fitter.
What affects the cost of remedial sealant
We quote each job individually. This is what makes a difference:
- Access and height
- How much old sealant there is and how hard it is to remove
- When we can work, for business premises
- Which sealant suits the joint
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Roughly how big the job is
- The type of property
- Photos by email, if that’s easy
- What’s wrong with the joints now
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work.

Remedial sealant around South Mundham
South Mundham is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Letting a property close to Chichester station? Then a joint that keeps failing is best fixed properly while the property is empty. In the older streets around The Parish Church of St Stephen, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

What we’re called out for in South Mundham
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks. Then the only fix is removal and a new bead.
Look out for any of the following:
- A shower that leaks however often it’s resealed
- Mould trapped under a layer of silicone
- Sealant applied over old sealant that has lifted
- Thick, messy sealant smeared over tiles
Schools such as North Mundham Primary School are buildings too, and washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
What to look for in a quote
- Who does the work, and how experienced they are
- Whether the sealant suits the joint
- How the joint is cleaned and prepared
- Whether they’re fully insured
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
What we cannot put right
To be straight with you, some problems need a different trade:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Older mastics that may need an asbestos check before removal
- Failed tanking or loose tiles behind the sealant
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.
