How we handle remedial sealant in Owslebury
Some sealant jobs aren’t a simple reseal, because someone has already had a go. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out before the joint can be done properly. We work on failed movement joints, mouldy bath & shower sealant and leaking tray & enclosure joints, and people most often call us about beads that never stuck properly and torn expansion joints.
For a small place like Owslebury, remedial sealant is planned like any other job: the journey and access are simply agreed in advance. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
There’s a 12-month guarantee on every job.

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.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.

Does remedial work come with a guarantee?
Yes, with our 12-month guarantee. If we’ve pointed out another problem, getting it fixed helps the new joint last.

What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for most joints, depending on how much old sealant has to come out, and the area is left clean. In a small place like Owslebury, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in
Getting a quote
Asking for a quote is easy: let us know the job and the location and its rough size. A few photos by email make the job easier to understand, and we will take it from there.
Related advice
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Have loose fittings fixed before resealing
- Use a soft cloth, not a scourer, on silicone
- Keep movement joints clear of mortar and paint
- Never seal over old silicone
Give the new sealant its full cure time: follow the cure time we give you.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.
Remedial sealant around Owslebury
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
In the older streets around Church of St Andrew, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Managing a site like Owslebury Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

Signs you need remedial sealant in Owslebury
One of the commonest remedial jobs is sealant on top of sealant. New silicone cannot stick to the old bead, so the top layer lifts and water and mould collect between the two.
Keep an eye out for any of the following:
- Repeat leaks from the same joint
- Decorators’ caulk around a bath or shower
- Worktop sealant that has shrunk and split
- Beads that never stuck properly
Letting a property close to Shawford station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- How the surfaces are prepared before sealing
- What insurance they hold
- When the joint can take water or movement
Surface by surface
Mouldy bath & shower sealant
Mould that has grown into silicone does not clean out for good. The sealant is cut out completely, the joint treated with a mould remover and dried before anti-fungal sanitary silicone goes in.
Worktops & kitchens
A loose worktop splits its sealant. It needs fixing down first, and we will tell you if we find it.
