What remedial sealant looks like in Bosham
Bosham is within about 2 miles of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. Bosham has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
In the older streets around The United Reformed Church, walls and floors in older homes can move, and sealant and grout show it first. For site and facilities teams at buildings such as Bosham Primary School, 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.

Remedial sealant in Bosham, done properly
Getting old sealant out properly is slow, careful work. We cut out every layer, clear the residue and degrease the surfaces, without scratching tiles, trays or frames. New sealant only bonds to a clean, dry joint. We work on expansion joints, failed movement joints and leaking tray & enclosure joints, and the jobs we see most are floor or wall movement joints that have failed and kitchen joints letting water behind the worktop.
Around Bosham, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
You get a 12-month guarantee, the same in Bosham as everywhere else we work.

Other services in Bosham
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
We also work for property managers and facilities teams. Several sites can be quoted together, and we are fully insured for the work.
Bosham: your questions answered
Can you help a landlord with a rental near Bosham station?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you cover smaller places like Bosham?
Yes. Bosham is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we are fully insured.
How long does the work take?
Allow a few hours for a typical bath or shower, longer where several layers have been applied. We’ll give you a timescale when we quote.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What happens if it’s left?
Leaks that are left keep doing damage out of sight: soaked floorboards, ceiling stains below and blown plaster. By comparison, sorting the joint is quick. In a small place like Bosham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

What the job involves on each surface
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, tray edges and screen profiles included.
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out.
When to call us in Bosham
Products get mixed up: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. Each fails in its own way.
If you can see any of these, it’s time to have the joints looked at:
- Mould trapped under a layer of silicone
- Sealant applied over old sealant that has lifted
- Torn expansion joints
- Gaps opening along the back of the worktop
For landlords with property near Bosham station, botched sealant from a previous quick fix is easier to strip out between tenants.
Questions to ask before booking
- How long the guarantee is
- Whether all the old sealant comes out first
- Whether the sealant suits the joint
- Whether VAT is included
Can I do it myself?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
When it isn’t the sealant
We’d rather tell you now than do work that won’t last, so these are the limits:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Sealant in an older building that needs testing for asbestos first
- A tray or worktop that needs refixing first
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before you book.
Joints and surfaces we work on
- Expansion joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Shrunken worktop sealant
- Failed movement joints
- Leaking tray & enclosure joints
How it works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours, depending on how many layers have to come out, depending on the amount of work. For a village or hamlet like Bosham, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking the joint for movement, leaks and the reason it failed.
- All the old sealant comes out, including any layers underneath.
- We clean the joint, treat any mould and let it dry.
- Moving joints get backing and a flexible sealant to suit.
- The new joint is tooled neatly and we explain anything else we found.
How to prepare
- Clear the area around the work
- Mention if the joints have been sealed before
- For business premises, tell us about site rules or sign-in
