Remedial Sealant in Oxgangs
We cover Oxgangs for removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Kitchen joints letting water behind the worktop
- Products that weren’t meant for the joint
- Torn expansion joints
The process
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for most joints, depending on how much old sealant has to come out, depending on the size of the job. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Oxgangs, it helps to know the floor, the door entry arrangements and the nearest parking.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.
- Moving joints get backing and a flexible sealant to suit.
- Finally we finish the joint and talk you through what we found.
Before we arrive
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work

About our remedial sealant in Oxgangs
Water on the floor doesn’t always mean failed silicone. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. If that is what we find, we will tell you rather than reseal something that won’t fix it. Typical jobs include decorators’ caulk around a bath or shower and beads that never stuck properly, across leaking tray & enclosure joints, botched or over-sealed joints and shrunken worktop sealant.
Scotland’s cities have a lot of flats, from sandstone or granite tenements to modern blocks, as well as houses in the suburbs. Generally soft Scottish water means less limescale, but steam and poor ventilation still let mould into the sealant and grout.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Air the bathroom so the sealant can dry
- Find out why the sealant failed first
- Never seal over old silicone
- Do not wait for a small gap to become a leak
Where we have pointed out another fault, have it put right, because the new sealant can’t hold back a problem underneath.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Signs you need remedial sealant in Oxgangs
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, so it starts lifting sooner than it should.
Common reasons people contact us include:
- Decorators’ caulk around a bath or shower
- Leaks that keep coming back after resealing
- Wide, uneven beads that look worse than the old ones
- Worktop sealant that has shrunk and split
For site and facilities teams at buildings such as Firrhill High School, we reseal washrooms and kitchens in schools and businesses as well as homes.
Questions to ask before booking
- Is the old sealant removed completely?
- What preparation is included
- How much experience the applicator has
- Is VAT in the price?
Remedial sealant in Oxgangs: local notes
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 includes keeping fixtures and fittings in reasonable repair. Failed sealant around a bath or shower is worth sorting between tenancies.
If you let a flat or house near Slateford station, a joint that keeps failing is best fixed properly while the property is empty.

Different surfaces, different methods
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, including the screen profile and tray edges.
Mouldy bath & shower sealant
Repeat mould usually points to a damp, poorly aired room. We will reseal and tell you if extraction looks to be the issue.
Questions from Oxgangs
Can a failed shower seal in a tenement flat in Oxgangs leak into the flat below?
Yes, it can. In a tenement, water that gets past failed sealant or cracked grout can run under the bath or tray and through to the ceiling below. It’s worth sorting sealant and grout before it gets that far.
Do you work for landlords with property near Slateford station?
Yes, rental work is part of what we do. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
Where are you based?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. We’ll take all the sealant out, look for why it failed and reseal it properly.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Can you strip sealant from an acrylic tray safely?
Yes, with care. The old bead is cut and lifted with tools that suit the surface, then clean off the residue. We point out any damage that is already there.
Someone sealed over the old bead. Can you fix it?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s what makes the new bead last.
