How we handle remedial sealant in Strachan
In Strachan, as anywhere, remedial jobs tend to look alike: over-sealed joints, hidden mould, repeat leaks and split movement joints. Each is stripped back and done again properly. If you have worktop sealant that has shrunk and split and sealant applied over old sealant that has lifted, we can put it right, on botched or over-sealed joints, shrunken worktop sealant and mouldy bath & shower sealant alike.
A bathroom in a place like Strachan gets the same daily wear as one in a city flat. Limescale is less of a problem with Scotland’s generally soft water, but mould still takes hold in damp sealant and grout.
Whatever the size of the job, you get the same one-year guarantee.

Strachan questions
Is Strachan in your area for remedial sealant?
Yes. Our work covers the whole of Scotland, and Strachan is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
Is Strachan within the area you cover?
Yes, we do. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you have insurance?
Yes. Mr Mastic is fully insured.
Can I choose the sealant colour?
Yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before we start.
Do you work for letting agents?
Yes. We work for householders, landlords, letting agents, businesses and hotels across Aberdeenshire.
What if resealing will not fix my leak?
We will tell you. If it’s a cracked tray, a failed valve or a leaking waste, resealing won’t fix it, so we won’t pretend it will.
Can you take off two layers of silicone?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s what makes the new bead last.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
How it works
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours, depending on how many layers have to come out, depending on the size of the job. Outdoor work around Strachan depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- 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.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Tell us if parking is tricky
- Clear items away from the joints we are working on
- For indoor joints, keep the area dry beforehand if you can

Advice
What we can’t put right
To be straight with you, there are a few things sealant won’t fix:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A tray or worktop that needs refixing first
- Failed tanking or loose tiles behind the sealant
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly before booking.
Surfaces we seal
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Failed movement joints
- Expansion joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
Why it’s worth doing now in Strachan
Another bead over the top won’t fix a failed joint. It does not grip the old layer, leaving the leak in place and one more layer to cut out later. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Get the cause of a repeat leak found before resealing
- Act on a lifting corner right away
- Keep bleach and abrasives off the bead
- Always have old sealant cut out, not covered
Where we’ve pointed out another fault, have it put right, because the new sealant can’t hold back a problem underneath.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
What remedial sealant looks like in Strachan
Private landlords in Scotland must be registered and meet the Repairing Standard, which includes keeping fixtures and fittings in reasonable repair. Failed sealant around a bath or shower is worth sorting between tenancies. Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. Mould is another matter: a bathroom that stays damp still turns sealant and grout black.
In and around Strachan, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

Surface by surface
Windows & doors
Frames resealed over the top end up with hard, layered mastic. We remove it all and clean back to sound surfaces.
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We work carefully to avoid adding to it, and tell you about any damage we find.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you are 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 does not work out, we can still put it right.

Common problems we fix in Strachan
Joints that move need sealant that can stretch. Flexing baths, rocking trays and building movement joints will split a rigid or thin bead.
If you can see any of these, it’s time to have the joints looked at:
- Black mould underneath the bead
- Repeat leaks from the same joint
- Smears and lumps from a botched reseal
- Over-sealed joints coming away
In the older streets around Strachan Parish Church And Churchyard, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
