Remedial sealant & repairs in Barnton, Edinburgh
Professional remedial sealant in and around Barnton, with every bit of old sealant taken out first and a one-year guarantee.
- A shower that leaks however often it’s resealed
- Worktop sealant that has shrunk and split
- A second bead peeling off the first
Why act early in Barnton
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. Private landlords in Barnton must meet the Repairing Standard, and damp or leaks can fall short of it, so failed sealant is best replaced before it becomes a complaint.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Why choose Mr Mastic in Barnton

Remedial sealant for homes and businesses in Barnton
If a joint fails again and again, something is causing it. Movement, the wrong product or a leak from somewhere else will defeat even a perfect bead. We look for the cause before we reseal. If you have dark patches showing through the sealant and smears and lumps from a botched reseal, we can put it right, whatever the surface.
In Scotland’s cities, including the area around Barnton, many older flats had their bathrooms added into small rooms later on. Rooms like that are often small and slow to dry out, and steam with nowhere to go is what turns sealant black and grout grey.
Each job carries a 12-month guarantee, whatever its size.

How it works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for most joints, depending on how much old sealant has to come out. Parking in city streets around Barnton can be tight or controlled, so it helps to know about permits or nearby bays. If you are in a flat, let us know how we get in at the street door.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- 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.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive

When it is not the sealant
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Cracks in the fitting rather than the joint
- Tiles that have come away from the wall
- A bath, tray or worktop that moves until it’s properly fixed
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly before you book.
Joints and surfaces we work on
- Failed movement joints
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Expansion joints
- Shrunken worktop sealant
Different surfaces, different methods
Mouldy bath & shower sealant
Black mould inside the bead will not scrub out. The sealant is cut out completely, the joint treated with a mould remover and dried before anti-fungal sanitary silicone goes in.
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We take care not to make it worse, and point out any existing damage.
What we are called out for in Barnton
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks, especially in damp, poorly aired rooms. Then the only fix is removal and a new bead.
The most common problems we see are:
- Products that weren’t meant for the joint
- Beads that never stuck properly
- Torn expansion joints
- Black mould underneath the bead
If you let a flat or house near Edinburgh Gateway station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
Before you book anyone
- Which sealant they’ll use, and why
- Who does the work, and how experienced they are
- The length of the guarantee
- Is VAT in the price?
Looking after it afterwards
Looking after new joints is easy:
- Find out why the sealant failed first
- Keep movement joints clear of mortar and paint
- Report a tray that rocks or a worktop that lifts
- Never seal over old silicone
If the joint ever needs renewing, have it cut out, not sealed over. New silicone does not bond to old, so the old bead should always come out first.
Warning signs: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Any of them means it’s time for remedial work.
Bathrooms and kitchens in Barnton
Barnton is within about 1 mile of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. 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.
For site and facilities teams at buildings such as Craigmount High School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Barnton questions
Do you work for landlords with property near Edinburgh Gateway station?
Yes, we work for letting agents and landlords. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Is Barnton in your area for remedial sealant?
Yes, Barnton is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
How long will it take to strip and reseal the joint?
Longer than a simple reseal, because every layer has to come out. For most joints, it’s a few hours, and we confirm the time with your quote.
