Remedial sealant for homes and businesses in Back
If a joint has been resealed and is leaking again, it’s worth a proper look. Send photos when you drop us a line at info@mrmastic.co.uk. If you have repeat leaks from the same joint and a second bead peeling off the first, we can put it right.
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 generally the first signs.
The work is covered for a year after we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

How the job changes by surface
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant won’t fix it. We’ll tell you what we find.
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We take care not to make it worse, and point out any existing damage.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured for the work.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
FAQs for Back
Will you come out to Back?
Yes, we do. We work across all of Scotland, islands included, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is remedial sealant in Back guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you fix a reseal that hasn’t worked?
Yes. There’s normally a reason: sealant over sealant, movement or another leak, and we deal with the cause first.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
What we do, step by step
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes a few hours, depending on how many layers have to come out in most cases. For a place like Back, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- 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.
How to prepare
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work
- Move anything stored near the joints

When something else is needed
New sealant cannot fix everything, and we will tell you before any work starts. It will not solve:
- Sealant in an older building that needs testing for asbestos first
- Tiles that have come away from the wall
- A cracked shower tray or bath (that needs repair or replacing)
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.
Joints and surfaces we work on
- Failed movement joints
- Expansion joints
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Shrunken worktop sealant
Why it’s worth doing now in Back
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. 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.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

What remedial sealant looks like in Back
Back is within about 1 mile of 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.
Around Back, as everywhere, remedial sealant is only as good as the preparation behind it. For jobs in and around Back, choosing the right material for each joint is as important as a tidy finish.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
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.
