Remedial sealant in Prestonpans
Remedial work is what we do when sealant has failed or been done badly. New sealant over old, smeared beads, unsuitable products and hidden mould all have to come out before the joint can be done properly. We work on leaking tray & enclosure joints, shrunken worktop sealant and botched or over-sealed joints, and common reasons people get in touch are a second bead peeling off the first and beads that never stuck properly.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses. Where a building moves, cracked grout and split sealant are usually the first signs.
All of our work is guaranteed for twelve months.

What remedial sealant looks like in Prestonpans
Prestonpans is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. Mould is another matter: a bathroom that stays damp still turns sealant and grout black.
If you live in an older home near Prestongrange Parish Church, older homes can move a little, which is hard on rigid grout and tired sealant. For landlords with property near Prestonpans station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

How the visit works
There is not much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours, depending on how many layers have to come out from start to finish. Somewhere like Prestonpans may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Before we arrive
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints

Leave it or put it right?
Another bead over the top will not fix a failed joint. It can’t bond to what’s underneath, so the leak carries on and there’s now more to remove. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Do you need remedial sealant in Prestonpans?
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks. Then the only fix is removal and a new bead.
It’s worth asking for a quote if you see:
- Decorators’ caulk around a bath or shower
- Leaks that keep coming back after resealing
- Sealant that came away because the surface wasn’t prepared
- Over-sealed joints coming away
Managing a site like Preston Lodge High School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.
Questions to ask before booking
- Whether you can choose the colour
- What happens if they find a problem under the old sealant
- What preparation is included
- What product goes in the joint
When something else is needed
New sealant cannot fix everything, and we will tell you before any work starts. It won’t solve:
- Sealant in an older building that needs testing for asbestos first
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Cracks in the fitting rather than the joint
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think.

Should I try it myself first?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Looking after it afterwards
To keep the joints looking good and working properly:
- Clean sealant with mild products only
- Air the bathroom so the sealant can dry
- Deal with small splits early
- Don’t add new sealant on top of old
Keep the room ventilated: run the fan during and after showers, or open a window.
If a joint has failed more than once, stop resealing it. Have someone find out why, otherwise the next attempt will fail too.
