Remedial sealant for homes and businesses in Aberfoyle
Not every leak is a sealant leak. A cracked tray, a failed shower valve or a leaking waste can look just the same. When the fault is elsewhere, we say so instead of resealing for the sake of it. We work on leaking tray & enclosure joints, failed movement joints and botched or over-sealed joints, and people most often call us about movement joints that have split or pulled away and sealant applied over old sealant that has lifted.
For a place like Aberfoyle, 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.
Each job carries a 12-month guarantee.

Leave it or put it right?
Stripping out botched sealant adds time to a reseal, but rarely a lot: the work takes a few hours for most joints, depending on how much old sealant has to come out. Compared with chasing the same leak every few months, it’s time well spent. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

What remedial sealant looks like in Aberfoyle
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 Scotland, private landlords have to 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.
Homes close to St Mary's Church include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. Around Aberfoyle, as everywhere, remedial sealant is only as good as the preparation behind it.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Aberfoyle: your questions answered
What guarantee comes with remedial sealant in Aberfoyle?
All our work, in Aberfoyle and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Will you come out to Aberfoyle?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you fix expansion and movement joints?
Yes. Failed movement joints are cut out and resealed with backing and a flexible sealant suited to the movement.
Can you fix a reseal that hasn’t worked?
Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.
What does remedial sealant cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
What happens if the problem is the tray or the plumbing?
We will tell you. A cracked tray, faulty valve or leaking waste needs a different trade, so we will not pretend it will.
When it is not the sealant
In fairness, some problems need a different trade:
- Tiles that have come away from the wall
- Movement from fittings that aren’t supported
- Cracks in the fitting rather than the joint
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.

Surface by surface
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, tray edges and screen profiles included.
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so we spend extra time cleaning.
How it works
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. The job normally takes a few hours for most joints, depending on how much old sealant has to come out. Outside jobs in Aberfoyle need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints
How to get a quote
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, send an email to info@mrmastic.co.uk.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Use a soft cloth, not a scourer, on silicone
- Have loose fittings fixed before resealing
- Run the fan after every shower
- Always have old sealant cut out, not covered
Watch the joint over the first few weeks, particularly where the original failure was caused by movement. Should anything change, email us at info@mrmastic.co.uk.
If a joint has failed more than once, stop resealing it. Have someone find out why, otherwise the next attempt will fail too.
