Long Crendon Remedial Sealant
Failed sealant joints in Long Crendon need attention? We remove the old material, prepare the joints and seal them properly.
- Thick, messy sealant smeared over tiles
- Black mould underneath the bead
- Leaks that keep coming back after resealing
About our remedial sealant in Long Crendon
Getting old sealant out properly is slow, careful work. We cut out every layer, clear the residue and degrease the surfaces, without scratching tiles, trays or frames. Only then can new sealant bond. We work on failed movement joints, botched or over-sealed joints and shrunken worktop sealant, and the jobs we see most are decorators’ caulk around a bath or shower and beads that never stuck properly.
In a smaller place like Long Crendon, homes are mostly houses and bungalows rather than flats, from older cottages to newer builds. Sealant and grout wear out here just as they do in a big town.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

Your questions about remedial sealant in Long Crendon
Is Long Crendon within the area you cover?
Yes. Long Crendon is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Haddenham & Thame Parkway station. Can you help?

Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.
Is remedial work guaranteed?
Yes. Remedial work carries the same 12-month guarantee as all our work.
Can old silicone be taken off without scratching the tiles?
Yes. The old bead is cut and lifted with tools that suit the surface, and the residue is cleaned away. We point out any damage that’s already there.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Do you have insurance?
Yes. We are fully insured, and we can confirm the details when we quote.
Can failed expansion joints be resealed?
Yes. Where mortar or filler has been used instead of sealant, it’s removed where it can be, and reseal with a flexible product.
How the visit works
Before we leave, we go over the finished joints with you. The visit itself usually takes a few hours for most joints, depending on how much old sealant has to come out, depending on the size of the job. A visit to Long Crendon is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we find out how and where the joint has failed.
- Every layer of old sealant is cut and cleaned out.
- The joint is cleaned, treated for mould and left to dry.
- Moving joints get backing and a flexible sealant to suit.
- Finally we finish the joint and talk you through what we found.
Getting ready for the visit
- Mention any tricky access
- Clear the area around the work
- Let us know about parking restrictions

Signs you need remedial sealant in Long Crendon
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 any of the following:
- Wide, uneven beads that look worse than the old ones
- Sealant applied over old sealant that has lifted
- Repeat leaks from the same joint
- Dark patches showing through the sealant
In the older streets around Church of St Mary, walls and floors in older homes can move, and sealant and grout show it first.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
When it is not the sealant
To be straight with you, some problems need a different trade:
- Sealant in an older building that needs testing for asbestos first
- Plumbing leaks behind walls or under trays
- A cracked shower tray or bath (that needs repair or replacing)
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.
Surfaces we seal

- Botched or over-sealed joints

How to look after the new joints
After the cure time, these simple habits help:
- Do not add new sealant on top of old
- Have loose fittings fixed before resealing
- Find out why the sealant failed first
- Air the bathroom so the sealant can dry
If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant cannot hold back a problem underneath.
Warning signs: 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 quote in Long Crendon
The price is agreed before any work begins. It takes into account:
- Any mould that needs treating
- The type of sealant required
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

- Where the job is, and your postcode
- Any access issues, like height or stairs
- Photos by email, if that’s easy
- Roughly how big the job is
