Remedial sealant & repairs in Moredun, Edinburgh
Our applicators work in Moredun on removing failed, mouldy or leaking sealant and putting it right. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Kitchen joints letting water behind the worktop
- Smears and lumps from a botched reseal
- Repeat leaks from the same joint
Common problems we fix in Moredun
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks. Then the only fix is removal and a new bead.
Keep an eye out for these signs:
- Dark patches showing through the sealant
- Torn expansion joints
- Sealant that came away because the surface wasn’t prepared
- Over-sealed joints coming away
If you look after a building such as Liberton High School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
What your quote should include
- How much experience the applicator has
- Which colour the sealant will be
- Whether all the old sealant comes out first
- What product goes in the joint
About our remedial sealant in Moredun
Remedial jobs in Moredun usually fall into a few patterns: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. Each is stripped back and done again properly. Typical jobs include movement joints that have split or pulled away and black mould underneath the bead, across failed movement joints, shrunken worktop sealant and botched or over-sealed joints.
From stone-built tenements to new flats and suburban houses, Moredun is in a city with every kind of home. Scottish water is generally soft, so limescale is less of a problem than in hard-water areas, but mould still grows into sealant and grout in a steamy bathroom.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Remedial sealant in Moredun: local notes
Moredun is close to 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. 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.
Rented homes near Shawfair station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants. Homes close to Liberton Parish Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

What affects the quote in Moredun
For a quick quote, just ask. The main things that affect it are:
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- Mould in or behind the old joints
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
What to tell us for a quote
To help us quote quickly, please include:
- A few pictures by email, if you can
- The rough size of the job
- If it’s domestic, commercial or a hotel
- What’s wrong with the joints now
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, send an email to info@mrmastic.co.uk.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Don’t point over movement joints
- Clean sealant with mild products only
- Never seal over old silicone
- Ask why a joint failed before redoing it
Clean gently: no scraping, scouring pads or harsh chemicals.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.

How the visit works
Good joint work is mostly preparation, so that’s 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 a typical bath or shower, longer where several layers have been applied. Inside a flat in Moredun, the job is planned with you; outside, shared parts may need the factor or other owners involved. It helps to know which it is when you get in touch.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.

Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, tray edges and screen profiles included.
Windows & doors
Frames resealed over the top end up with hard, layered mastic. All of it is cut out and the frame and wall cleaned before backing and resealing.
Why it’s worth doing now in Moredun
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 removal is most of a remedial job. In a tenement flat in Moredun, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
Instead of a standard rate, 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.
