How we handle remedial sealant in Mark Cross
Not every leak is a sealant leak. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that is what we find, we’ll tell you rather than reseal something that will not fix it. If you have movement joints that have split or pulled away and decorators’ caulk around a bath or shower, we can put it right.
Being in a small place like Mark Cross makes no difference to the job itself: the journey and access are simply agreed in advance. In the bathroom or kitchen, the work is the same as in any town.
A one-year guarantee comes as standard, so you are covered after we’ve gone.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Bathrooms and kitchens in Mark Cross
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
Rented homes near Wadhurst station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. If you live in an older home near St Marks, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

What we do, step by step
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours, depending on how many layers have to come out for a typical job. For a village or hamlet like Mark Cross, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking the joint for movement, leaks and the reason it failed.
- We strip the joint completely, removing any layers below.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- Finally we finish the joint and talk you through what we found.
Before we arrive
- Move anything stored near the joints
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before

I let a flat near Wadhurst station. Can you help?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Is Mark Cross within the area you cover?
Yes. Mark Cross 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.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.

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.

Yes. White, clear and grey are common, and other colours are available, and we’ll agree it with you first.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.

How we quote for remedial sealant
For a quick quote, just ask. The main things that affect it are:
- The size of the job
- Whether the work is at height
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.
Helping us quote
What to tell us when you ask for a quote:
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
- If someone has resealed it before
- If it’s domestic, commercial or a hotel
For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we’ll explain what’s involved.
When to call us in Mark Cross
One of the commonest remedial jobs is sealant on top of sealant. New silicone can’t stick to the old bead, so the new layer peels, and damp and mould settle between them.
Look out for these signs:
- Gaps opening along the back of the worktop
- A shower that leaks however often it’s resealed
- Movement joints that have split or pulled away
- Over-sealed joints coming away
If you look after a building such as Mark Cross Church of England Aided Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

How the job changes by surface
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, including the screen profile and tray edges.
Over-sealed & botched joints
Every layer has to come out, including the smears and film on surrounding tiles. Only a clean joint will take a new bead.
