Remedial sealant in Denholm, done properly
Remedial work is what we do when sealant has failed or been done badly. New sealant over old, smeared beads, unsuitable products and hidden mould all need stripping out. If you’re dealing with a shower that leaks however often it’s resealed and decorators’ caulk around a bath or shower, we can help.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses. Where a building moves, cracked grout and split sealant are usually the first signs.
Our work is backed for twelve months.

What we do, step by step
There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours for a typical bath or shower, longer where several layers have been applied. Outdoor work around Denholm depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- First we find out how and where the joint has failed.
- We strip the joint completely, removing any layers below.
- 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.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can

Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Is Denholm within the area you cover?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
When is the sealant fully cured?
Cure times vary by product. Before we leave, we will tell you the cure time.
What should I tell you?
A short description and the location, plus photos if you have them. We will ask anything else we need to know.
Where is Mr Mastic based?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Can you reseal a split movement joint?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Are you insured?
Yes. We are fully insured for domestic and commercial work.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Do you need remedial sealant in Denholm?
Some joints fail because water is reaching them from behind. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.
People normally contact us after spotting one of these:
- Mould trapped under a layer of silicone
- Movement joints that have split or pulled away
- Repeat leaks from the same joint
- Wide, uneven beads that look worse than the old ones
For an older house near a landmark such as Minto Parish Church, older homes can move a little, which is hard on rigid grout and tired sealant.

What sealant work can’t fix
We’d rather tell you now than do work that will not last, so these are the limits:
- A tray or bath that’s cracked
- Failed tanking or loose tiles behind the sealant
- Sealant in an older building that needs testing for asbestos first
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.
Joints and surfaces we work on
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Botched or over-sealed joints
- Failed movement joints
- Leaking tray & enclosure joints
- Expansion joints
Why act early in Denholm
Stripping out botched sealant adds time to a reseal, but rarely a lot: the work takes a few hours for a typical bath or shower, longer where several layers have been applied. Compared with chasing the same leak every few months, it’s time well spent. In a place like Denholm, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.
Why us?
- Over 20 years’ experience
- Neat joints and a tidy finish
- A choice of colours where the product allows
- Colour picked to suit the job

Remedial sealant around Denholm
Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. 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 covers keeping fixtures and fittings in a reasonable state of repair. Tired, leaking sealant is worth putting right before a new tenant moves in.
For site and facilities teams at buildings such as Craigmount School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

How the job changes by surface
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. We treat the exposed joint once the bead is out.
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant will not fix it. We’ll tell you what we find.
Aftercare tips
So the new joints stay in good condition:
- Keep bleach and abrasives off the bead
- Look for stains below bathrooms now and then
- Never fill a movement joint with mortar or grout
- Don’t wait for a small gap to become a leak
Do not let anyone seal over it later. New silicone does not bond to old, so the old bead should always come out first.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
