Surface by surface
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so we spend extra time cleaning.
Mouldy bath & shower sealant
Mould that has grown into silicone doesn’t clean out for good. All of it comes out, and the joint is treated and dried ahead of a new anti-fungal bead.
Remedial sealant in Thornwood, done properly
If a joint fails again and again, something is causing it. Movement, the wrong product or a leak from somewhere else will defeat even a perfect bead. We look for the cause before we reseal. Common call-outs are for sealant applied over old sealant that has lifted and products that weren’t meant for the joint, on expansion joints, shrunken worktop sealant and botched or over-sealed joints.
From stone-built tenements to new flats and suburban houses, Thornwood 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.
Each job carries a 12-month guarantee, large or small.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Find out why the sealant failed first
- Air the bathroom so the sealant can dry
- Look for stains below bathrooms now and then
- Do not point over movement joints
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
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.
What else we do in Thornwood
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Why deal with it now?
Stripping out botched sealant adds time to a reseal, but rarely a lot: the work takes a few hours for most joints, depending on how much old sealant has to come out. Compared with chasing the same leak every few months, it’s time well spent. In a tenement flat in Thornwood, 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.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.
Why book with us
- Old sealant always removed completely
- White, clear, grey or coloured to suit, where the product allows

Your questions about remedial sealant in Thornwood
Could a leaking bath seal in my Thornwood flat reach the neighbours below?
Yes, and the first sign is often a mark on the ceiling below. Cutting out the old sealant and laying a fresh bead puts a stop to it.
I let a flat near Partick station. Can you help?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned.
Is there any odour?
Some sealants have a smell while they cure. Opening a window helps.
How long before the joint can be used?
It depends on the product and the conditions. Before we leave, we’ll tell you the cure time.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can you take off two layers of silicone?
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 cover Thornwood?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, Thornwood included.
How the visit works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours, depending on how many layers have to come out. In a city area like Thornwood, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.
- First we find out how and where the joint has failed.
- All the old sealant comes out, including any layers underneath.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- The new joint is tooled neatly and we explain anything else we found.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Keep children and pets away from the work area
- Mention any tricky access

Signs you need remedial sealant in Thornwood
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks, faster where ventilation is poor. Then the only fix is removal and a new bead.
The most common problems we see are:
- Kitchen joints letting water behind the worktop
- Sealant that came away because the surface wasn’t prepared
- Caulk or the wrong sealant used in a wet area
- Leaks that keep coming back after resealing
Letting a property close to Partick station? Then botched sealant from a previous quick fix is easier to strip out between tenants.
