How we handle remedial sealant in Selsey
Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. We work on leaking tray & enclosure joints, expansion joints and botched or over-sealed joints, and people most often call us about floor or wall movement joints that have failed and a second bead peeling off the first.
Most bathrooms in a town like Selsey are in family homes, used every day, which is hard on sealant and grout. Black mould along the bath, a lifting bead by the sink or crumbling grout in the shower are the usual signs.
Whatever the size of the job, you get the same one-year guarantee in Selsey and across West Sussex.

Why deal with it now?
DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. Gaps in sealant and mould in the bead never get better on their own, and in a busy household in Selsey they spread with every shower and every downpour. Now is the easy time to put it right.
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. We take all of that into account in your quote.

Selsey homes and their sealant
Selsey is within about 1 mile 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. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
For an older house near a landmark such as St Peter's Church, older homes can move a little, which is hard on rigid grout and tired sealant.

Looking after it afterwards
To keep the joints looking good and working properly:
- Keep movement joints clear of mortar and paint
- Keep the room well ventilated
- Use a soft cloth, not a scourer, on silicone
- Do not add new sealant on top of old
Keep the room ventilated: run the fan during and after showers, or open a window.
If a joint has failed more than once, stop resealing it. Have someone find out why, or the next bead will go the same way.

What else we do in Selsey
Do you need remedial sealant in Selsey?
How a joint is built matters as much as the product. Sealant packed too deep, or stuck to the back of the joint as well as the sides, cannot stretch, and tears at the first real movement. Backing sets the depth and stops that.
The problems people usually mention when they call are:
- Leaks that keep coming back after resealing
- Sealant that came away because the surface wasn’t prepared
- Movement joints that have split or pulled away
- Black mould underneath the bead
If you look after a building such as Seal Primary Academy, 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 turns up on the day
- What the cure time is
- Are they insured?
- What happens if the job turns out different
Can I do it myself?
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.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Quotes for remedial sealant in Selsey
Some jobs are bigger than they look, and some smaller. The main factors:
- When we can work, for business premises
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- Whether the work is at height
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
Helping us quote
You do not need to know the technical terms. It helps if you can tell us:
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
- Roughly how big the job is
- If someone has resealed it before
We do not publish a price list, because every job is different. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or drop us an email.
Selsey questions
Is Selsey in your area for remedial sealant?
Yes, Selsey is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
Is remedial sealant in Selsey guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
Are you fully insured?
Yes. We’re fully insured for every job we do.
Do you work for letting agents?
Yes. As well as householders, we work for landlords, agents, businesses and hotels across West Sussex.
What happens if the problem is the tray or the plumbing?
We’ll tell you. If it’s a cracked tray, a failed valve or a leaking waste, resealing won’t fix it, and we will not reseal for the sake of it.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
What happens on the day
Before we leave, we go over the finished joints with you 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 job in Selsey, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- 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.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints

Different surfaces, different methods
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. We check both before any new sealant goes on.
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We work carefully to avoid adding to it, and tell you about any damage we find.
