Remedial Sealant in Craigmillar
Our applicators work in Craigmillar on removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Beads that never stuck properly
- Worktop sealant that has shrunk and split
- Black mould underneath the bead
Remedial sealant in Craigmillar
A joint that keeps letting you down needs more than another bead. Send pictures when you email us at info@mrmastic.co.uk, and say how long ago it was last done. We work on expansion joints, shrunken worktop sealant and botched or over-sealed joints, and people most often call us about leaks that keep coming back after resealing and gaps opening along the back of the worktop.
In Scotland’s cities, including the area around Craigmillar, 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.
All our work is covered by our one-year guarantee.

Looking after it afterwards
Aftercare is simple:
- Get the cause of a repeat leak found before resealing
- Clean sealant with mild products only
- Always have old sealant cut out, not covered
- Don’t point over movement joints
Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
What we’re called out for in Craigmillar
Movement tears sealant that is not designed for it. Flexing baths, rocking trays and building movement joints split any bead that’s too stiff or too thin.
Look out for these signs:
- A second bead peeling off the first
- Decorators’ caulk around a bath or shower
- Repeat leaks from the same joint
- Kitchen joints letting water behind the worktop
For site and facilities teams at buildings such as Castlebrae Community High School, we reseal washrooms and kitchens in schools and businesses as well as homes.

What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a typical bath or shower, longer where several layers have been applied. Inside a flat in Craigmillar, the job is planned with you; outside, shared parts may need the factor or other owners involved. Tell us which applies when you book.
- 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.
- The joint is tooled and you are told about anything else we found.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions
- On commercial sites, let us know about site rules

When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Older mastics that may need an asbestos check before removal
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Water damage behind tiles that needs a tiler
If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer before booking.

Remedial sealant in Craigmillar: local notes
Craigmillar is within about 3 miles of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. In Scotland, private landlords have to meet the Repairing Standard, which includes keeping fixtures and fittings in reasonable repair. Tired, leaking sealant is worth putting right before a new tenant moves in.
In the older streets around Robin Chapel, timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you let a flat or house near Brunstane station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
Craigmillar is about 2 miles east of Newington, in Edinburgh. Whether you are in the middle of Craigmillar or further out, remedial sealant is available for homes and businesses alike. Craigmillar is one of 175 towns and villages in Edinburgh we cover for remedial sealant.

Why act early in Craigmillar
Hidden water does the most damage: soaked floorboards, ceiling stains below and blown plaster. Dealing with the joint now is a small job by comparison. Scottish rain finds any gap around a frame or wall joint, and in a tall building in Craigmillar, damp can travel a long way before it shows.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Take a look at how sealant jobs are priced and what customers say.
Different surfaces, different methods
Movement & expansion joints
A sealant stuck to the back of the joint can’t stretch. Backing rod or bond-breaker tape prevents it, so the sealant grips the two sides only.
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. We strip it, degrease the joint and reseal in a colour to suit.
Craigmillar questions
Do you work in hotels near Craigmillar?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Could a leaking bath seal in my Craigmillar flat reach the neighbours below?
It can. Tenement floors are generally timber, and water from a failed seal can find its way down to the flat below. Replacing tired sealant early is the simplest way to avoid that.

Yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before any work starts.

Yes. You get our 12-month guarantee.

Yes. From our base in Crawley, we cover South East England, London and all of Scotland, Craigmillar included.
