How the visit works
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. The work normally takes a few hours, depending on how many layers have to come out. In a small place like Sacombe, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- 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.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Remedial sealant in Sacombe
Two decades of sealant work means we recognise most failures quickly. We are ARBOMaster approved and fully insured, and every remedial job comes with a 12-month guarantee. We work on shrunken worktop sealant, expansion joints and mouldy bath & shower sealant, and people most often call us about wide, uneven beads that look worse than the old ones and worktop sealant that has shrunk and split.
Being in a small place like Sacombe makes no difference to the job itself: it just means planning the journey and access beforehand. In the bathroom or kitchen, the work is the same as in any town.
Your job is guaranteed for a year, as with all our work.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Aftercare tips
After the cure time, these simple habits help:
- Don’t point over movement joints
- Do not add new sealant on top of old
- Check ceilings under showers for marks
- Report a tray that rocks or a worktop that lifts
Give the new sealant its full cure time: generally around 24 hours, or as long as we advise.
Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Each one is worth getting looked at.
What affects the cost of remedial sealant
For a quick quote, just ask. The main things that affect it are:
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
- Whether there’s mould to deal with
- The number of rooms or windows
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- What’s wrong with the joints now
- The rough size of the job
- Photos by email, if that is easy
- Whether it has been sealed before
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you are ready, call 0345 464 0079 or email us.
Sacombe homes and their sealant
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
If you live in an older home near Church of St Katherine, older homes can move a little, which is hard on rigid grout and tired sealant.

When it isn’t the sealant
It helps to know what we can’t do too:
- Older mastics that may need an asbestos check before removal
- A bath, tray or worktop that moves until it’s properly fixed
- Cracks in the fitting rather than the joint
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.
What we seal
- Leaking tray & enclosure joints
- Expansion joints
- Botched or over-sealed joints
- Failed movement joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
When to call us in Sacombe
A lot of failed joints have been sealed over rather than replaced. New silicone can’t stick to the old bead, so the new layer peels, and damp and mould settle between them.
Signs it’s time to call us include:
- Gaps opening along the back of the worktop
- A shower that leaks however often it’s resealed
- Torn expansion joints
- Sealant that came away because the surface wasn’t prepared
Letting a property close to Watton-At-Stone station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
Questions to ask before you book

Your questions about remedial sealant in Sacombe
Can you do remedial sealant in Sacombe?
Yes, Sacombe is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing.
Do you work for landlords with property near Watton-At-Stone station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Where are you based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Should I try DIY first?
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 you reseal a split movement joint?
Yes. The depth is set with backing so the sealant only bonds to the two sides.
Someone resealed my shower and it’s leaking again. Can you help?
Yes, generally. First we check whether the leak is the sealant at all, then the joints are stripped and resealed.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
Why deal with it now?
Mould under a bead cannot be reached by cleaning. Removal is the only way to get at it, so the joint can be treated and resealed. Where a wall is exposed, as many are in small places like Sacombe, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
