How we handle remedial sealant in Chirnside
If a joint has been resealed and is leaking again, it’s worth a proper look. Send pictures when you drop us a line at info@mrmastic.co.uk, along with when it was last resealed. If you have repeat leaks from the same joint and products that weren’t meant for the joint, we can help, whatever the surface.
For a place like Chirnside, 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. We just plan the journey and access beforehand.
Your job is guaranteed for a year, as with all our work.

What we do, step by step
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most joints, depending on how much old sealant has to come out. For a place like Chirnside, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- 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.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property

Why deal with it now?
Mould under a bead can’t be reached by cleaning. Removal is the only way to get at it, so the joint can be treated and resealed. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start.

- Anti-fungal sanitary silicone in wet areas

Do you need remedial sealant in Chirnside?
Products get mixed up: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. None of them last.
The problems people generally mention when they call are:
- Wide, uneven beads that look worse than the old ones
- Beads that never stuck properly
- Mould trapped under a layer of silicone
- A second bead peeling off the first
Letting a property close to Reston station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
Before booking anyone
- Whether you can choose the colour
- Is the old sealant removed completely?
- The length of the guarantee
- Whether they’re fully insured
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Keep the room well ventilated
- Look for stains below bathrooms now and then
- Find out why the sealant failed first
- 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.
Signs to act on: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Any of them means it’s time for remedial work.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Common questions in Chirnside
Can you do remedial sealant in Chirnside?
Yes. Our work covers the whole of Scotland, and Chirnside is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
I let a flat near Reston station. Can you help?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Someone sealed over the old bead. Can you fix it?
Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s what makes the new bead last.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses.
Where are you based?
We work from Crawley. Our applicators cover Chirnside.
What happens if the problem is the tray or the plumbing?
That’s why we look for the cause first. If the fault is elsewhere, you will know before any work is done.
How long does the work take?
The number of joints and layers decides it. You’ll have a timescale before any work begins.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Remedial sealant around Chirnside
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. Private landlords in Scotland must be registered and 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.
For site and facilities teams at buildings such as Chirnside Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. If you live in an older home near North Church, walls and floors in older homes can move, and sealant and grout show it first.

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
