Remedial sealant for homes and businesses in Scottish Borders
Two decades of sealant work means we recognise most failures quickly. We are fully insured ARBOMaster approved applicators, and every remedial job comes with a 12-month guarantee. We work on botched or over-sealed joints, leaking tray & enclosure joints and expansion joints, and the jobs we see most are sealant applied over old sealant that has lifted and caulk or the wrong sealant used in a wet area.
For a place like Scottish Borders, the job is the same as anywhere: everything old is cut out, the joints are cleaned and dried, and new sealant or grout goes in. The journey and access are simply planned in advance.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

What affects the quote in Scottish Borders
For a quick quote, just ask. The main things that affect it are:
- How easy the joints are to reach
- The amount of work
- Any mould that needs treating
- The old material and how stubborn it is
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
For a quote, email us at info@mrmastic.co.uk with the location and a short description of the problem. We’ll send you a clear quote before any work starts.
Landlords, agents and businesses in Scottish Borders
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
What we do, step by step
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours for most joints, depending on how much old sealant has to come out, including the tidy-up. Somewhere like Scottish Borders may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First we find out how and where the joint has failed.
- Every layer of old sealant is cut and cleaned out.
- We clean the joint, treat any mould and let it dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
How to prepare
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before
- Mention any tricky access
Getting a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
Advice
Signs you need remedial sealant in Scottish Borders
Movement tears sealant that isn’t designed for it. A bath that flexes, a tray that rocks or a building joint that opens and closes will split a rigid or thin bead.
If you can see any of these, it’s time to have the joints looked at:
- Beads that never stuck properly
- Movement joints that have split or pulled away
- Black mould underneath the bead
- A shower that leaks however often it’s resealed
If you live in an older home near Tweedsmuir Parish Church, walls and floors in older homes can move, and sealant and grout show it first.
Before you book anyone

- Whether all the old sealant comes out first

Scottish Borders questions
Is Scottish Borders in your area for remedial sealant?
Yes, Scottish Borders is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
Is Scottish Borders within the area you cover?
Yes, we do. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can you remove sealant that’s been put over old sealant?
Yes. We cut out all the layers and clean off the film, before resealing with a single bead.
When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you when we finish.
Do you work for letting agents?
Yes, often. Several properties can go on one quote.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can failed expansion joints be resealed?
Yes. Backing sets the depth and stops the sealant sticking to the back.
When it isn’t the sealant
To be straight with you, some problems need a different trade:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Water damage behind tiles that needs a tiler
- A bath, tray or worktop that moves until it’s properly fixed
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before you book.
Surfaces we seal
- Expansion joints
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Failed movement joints

Remedial sealant around Scottish Borders
Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. But mould still grows into sealant and grout in a room that does not dry out. Private landlords in Scotland must be registered and meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Failed sealant around a bath or shower is worth sorting between tenancies.
Around Scottish Borders, as everywhere, remedial sealant is only as good as the preparation behind it.

Typical jobs here are in homes near Crook Inn and the streets around them. Other landmarks nearby include Oliver Castle (0.9 miles south-west). The countryside around Scottish Borders includes Glenwhappen Rig.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Leave it or put it right?
A failed seal rarely means a new bathroom. If the bath, tray and tiles are sound, remedial resealing normally puts it right. Where something else has failed, you’ll hear it from us. Around Scottish Borders, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
