Remedial sealant in Whitwell, done properly
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. If you are dealing with caulk or the wrong sealant used in a wet area and floor or wall movement joints that have failed, we can help, whatever the surface.
Somewhere as small as Whitwell, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Why act early in Whitwell
A failed seal rarely means a new bathroom. If the bath, tray and tiles are sound, remedial resealing generally puts it right. If they’re not, we will tell you. In a small place like Whitwell, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

- Every job guaranteed for a year
- Over 20 years’ experience

Whitwell homes and their sealant
Whitwell 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, which wears sealant and grout out faster than in a quiet home. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Homes close to Church of St. Mary and St. Radegund include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. For site and facilities teams at buildings such as Niton Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Letting a property close to Shanklin station? Then a joint that keeps failing is best fixed properly while the property is empty.

We work in homes and buildings around The White Horse Inn and the streets around them. The nearest railway station is Shanklin station, about 4.5 miles north-east. Well-known places in the area include Arthur Webster Memorial Hospital for Children (4.5 miles north-east) and Blackgang Sawmill Museum (2.2 miles west). For a walk, there’s Stenbury Down.
How to look after the new joints
To keep the joints looking good and working properly:
- Never fill a movement joint with mortar or grout
- Do not wait for a small gap to become a leak
- Report a tray that rocks or a worktop that lifts
- Use a soft cloth, not a scourer, on silicone
Keep an eye on the joint at first, especially if movement was the problem. If anything changes, just ring 0345 464 0079 or email us.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
The process
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes a few hours for a typical bath or shower, longer where several layers have been applied, including the tidy-up. Somewhere like Whitwell 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.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in
- Mention any tricky access

Advice
Whitwell questions
Do you cover Whitwell for remedial sealant?
Yes, Whitwell is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.

Yes. We work for letting agents and landlords as well as householders. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Can you strip sealant from an acrylic tray safely?
Yes. We cut and lift the old sealant with tools suited to the surface, and the residue is cleaned away. Any existing damage is pointed out before any work starts.
Can you quote for more than one area?
Of course. Doing several areas at once is normally more efficient.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
What if resealing won’t fix my leak?
We check for that before we reseal. If we find the leak is elsewhere, we tell you before going further.

How we quote for remedial sealant
Jobs vary more than people expect. What affects the quote:
- Whether the work is at height
- The product the joint needs
- The size of the job
- Any mould that needs treating
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- What’s wrong with the joints now
- How we’d reach the joints
- Where the property is
- If someone has resealed it before
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, call 0345 464 0079 or send us an email.
