Remedial sealant in Charlestown
If a joint fails again and again, something is causing it. A tray that moves, a worktop that is not fixed, the wrong sealant or water getting in elsewhere will defeat even a perfect bead. Finding that cause comes before any new sealant. If you’re dealing with products that weren’t meant for the joint and sealant applied over old sealant that has lifted, we can put it right.
For a place like Charlestown, the job is the same as anywhere: old material out, joints cleaned and dried, and a fresh, even finish. We just plan the journey and access beforehand.
Big or small, it’s backed by our 12-month guarantee.

Surface by surface
Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, matched to the frame colour.
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, and silicone residue is cleaned off the tiles too. New sealant needs a fully clean surface.
How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most joints, depending on how much old sealant has to come out. Around Charlestown, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- 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.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you are told about anything else we found.
How to prepare
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints
- Mention any tricky access

Advice
Why it’s worth doing now in Charlestown
Remedial work takes longer than a straight reseal, but not by much: it takes a few hours, depending on how many layers have to come out. Compared with chasing the same leak every few months, it’s time well spent. In a place like Charlestown, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk and we will talk you through it.

Signs you need remedial sealant in Charlestown
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
These are the problems we are asked about most:
- Beads that never stuck properly
- Sealant applied over old sealant that has lifted
- A shower that leaks however often it’s resealed
- Dark patches showing through the sealant
Rented homes near Dunfermline City station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

Can old silicone be taken off without scratching the tiles?
Yes. Careful removal is most of a remedial job, particularly on softer surfaces like acrylic.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can you reseal a split movement joint?
Yes. Failed movement joints are cut out and resealed with backing and a flexible sealant suited to the movement.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
When something else is needed
In fairness, there are a few things sealant will not fix:
- Older mastics that may need an asbestos check before removal
- Failed tanking or loose tiles behind the sealant
- A bath, tray or worktop that moves until it’s properly fixed
If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before booking.

Bathrooms and kitchens in Charlestown
Charlestown is within about 1 mile of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. Private landlords in Scotland must be registered and meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Failed sealant around a bath or shower is worth sorting between tenancies.
If you live in an older home near Limekilns Parish Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Clean sealant with mild products only
- Find out why the sealant failed first
- Do not point over movement joints
- Never seal over old silicone
Keep an eye on the joint at first, particularly where the original failure was caused by movement. Should anything change, drop us a line at info@mrmastic.co.uk.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
