How we handle remedial sealant in Stanmore
A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. Typical jobs include thick, messy sealant smeared over tiles and a shower that leaks however often it’s resealed, on leaking tray & enclosure joints, expansion joints and botched or over-sealed joints.
Being in a small place like Stanmore 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.
A one-year guarantee comes with the work, just as it does everywhere we cover.

How the visit works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours, depending on how many layers have to come out. In a small place like Stanmore, access is normally 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.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you are told about anything else we found.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints

Different surfaces, different methods
Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, tray edges and screen profiles included.
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is generally part of the cause. Along with resealing, we will mention if the room needs better ventilation.
When something else is needed
In fairness, there are a few things sealant will not fix:
- A tray or worktop that needs refixing first
- Older mastics that may need an asbestos check before removal
- Cracks in the fitting rather than the joint
If you are not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.

Common problems we fix in Stanmore
Joint depth matters. A bead bonded on three sides, or laid too thick, can’t flex, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.
These are the problems we are asked about most:
- A shower that leaks however often it’s resealed
- Dark patches showing through the sealant
- Decorators’ caulk around a bath or shower
- Over-sealed joints coming away
In the older streets around Church of St Nicholas, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Don’t point over movement joints
- Check ceilings under showers for marks
- Run the fan after every shower
- Deal with small splits early
Watch the joint over the first few weeks, especially if movement was the problem. Should anything change, call 0345 464 0079 or send us an email.
If a joint has failed more than once, stop resealing it. Get the cause found first, or the next bead will go the same way.
FAQs for Stanmore
Is Stanmore within the area you cover?

Do I have to be there?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Do you have insurance?
Yes, we are fully insured for every job we do.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
How long will it take to strip and reseal the joint?
Allow a few hours for a typical bath or shower, longer where several layers have been applied. You’ll know the timing when we quote.
Where do you work from?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
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.
What happens if it’s left?
Adding more sealant is the usual quick fix, and it rarely works. It does not grip the old layer, so the leak carries on and there’s now more to remove. Older cottages and farmhouses around Stanmore can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.
