Welborne questions
Is Welborne within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Fareham station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can old silicone be taken off without scratching the tiles?
Yes. The old bead is cut and lifted with tools that suit the surface, then clean off the residue. Any existing damage is pointed out before any work starts.
What happens if the problem is the tray or the plumbing?
We check for that before we reseal. If the fault is elsewhere, you will know before any work is done.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Welborne.
Can failed expansion joints be resealed?
Yes. The depth is set with backing so the sealant only bonds to the two sides.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we are using and why.
Remedial sealant for homes and businesses in Welborne
Getting old sealant out properly is slow, careful work. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. New sealant only bonds to a clean, dry joint. We work on mouldy bath & shower sealant, botched or over-sealed joints and expansion joints, and common reasons people get in touch are leaks that keep coming back after resealing and a second bead peeling off the first.
Homes around Welborne are mostly houses and cottages rather than flats. Sealant and grout wear out here just as they do anywhere: everything old comes out before the new sealant or grout goes in.

What remedial sealant looks like in Welborne
Welborne is close to 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. There are hotels and other places to stay in and around Welborne. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
Homes close to Church of St Francis include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. Rented homes near Fareham station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

What affects the quote in Welborne

- Access and height
- Working hours on commercial sites
- The number and length of the joints
- Which sealant suits the joint
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
What we need to know
To make quoting easier, please include:
- The rough size of the job
- The address or postcode of the job
- Whether it’s a home or a business
- Whether it has been sealed before

Do you need remedial sealant in Welborne?
A lot of failed joints have been sealed over rather than replaced. Silicone does not bond to silicone, so the new layer peels, and damp and mould settle between them.
Signs it’s time to call us include:
- Caulk or the wrong sealant used in a wet area
- Sealant applied over old sealant that has lifted
- Leaks that keep coming back after resealing
- Worktop sealant that has shrunk and split
If you look after a building such as The Henry Cort Community College, 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.
Questions to ask before you book
- Whether they seal over old material or remove it
- How the joint is cleaned and prepared
- Who turns up on the day
- When the joint can take water or movement
Why act early in Welborne
Repeat failures have a cause. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. In a small place like Welborne, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

What sealant work can’t fix
Before booking, it’s worth knowing the limits too:
- Tiles that have come away from the wall
- A tray or worktop that needs refixing first
- Older mastics that may need an asbestos check before removal
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer.
Where we work in Welborne
- Botched or over-sealed joints
- Expansion joints
- Failed movement joints
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Shrunken worktop sealant
How the job changes by surface
Mouldy bath & shower sealant
Mould that has grown into silicone doesn’t clean out for good. The sealant is cut out completely, the joint treated with a mould remover and dried ahead of a new anti-fungal bead.
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed with a low-modulus product.
How it works
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours for most joints, depending on how much old sealant has to come out. For a village or hamlet like Welborne, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you are told about anything else we found.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Mention any tricky access
- Clear items away from the joints we’re working on
