About our remedial sealant in Botany
A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. We work on mouldy bath & shower sealant, botched or over-sealed joints and failed movement joints, and the jobs we see most are mould trapped under a layer of silicone and products that weren’t meant for the joint.
From stone-built tenements to new flats and suburban houses, Botany is in a city with every kind of home. Generally soft Scottish water means less limescale, but steam and poor ventilation still let mould into the sealant and grout.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What the job involves on each surface
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant will not fix it. We will tell you what we find.
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We take care not to make it worse, and tell you about any damage we find.
Why it’s worth doing now in Botany
Repeat failures have a cause. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
Doing several joints on one visit is usually more efficient than separate visits. You will get one clear quote for the whole job.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Never fill a movement joint with mortar or grout
- Find out why the sealant failed first
- Keep bleach and abrasives off the bead
- Have loose fittings fixed before resealing
Leave the new joint to cure fully before it gets wet or moves: usually around 24 hours, or as long as we advise.
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.
Bathrooms and kitchens in Botany
There are hotels and other places to stay in and around Botany. Hotel bathrooms are part of our work as well as homes, and can be done room by room. 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.
If you let a flat or house near Summerston station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. For site and facilities teams at buildings such as Cleveden Secondary 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.

Common questions in Botany
Can a failed shower seal in a tenement flat in Botany leak into the flat below?
Yes. With flats above and below, a leak from a failed seal rarely stays in one flat. A proper reseal, with all the old sealant cut out, stops it at the source.
Do you work for hotels and guest houses in Botany?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
What if the leak is not the sealant?
That is why we look for the cause first. If the fault is elsewhere, you’ll know before any work is done.
How much does remedial sealant cost in Botany?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can you fix a reseal that hasn’t worked?
Yes. Repeat leaks normally come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.
Where are you based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do you guarantee remedial jobs?
Yes. Our one-year guarantee covers the work, and we are ARBOMaster approved.

Want a quote for remedial sealant? Please drop us a line at info@mrmastic.co.uk with a few details. We’ll explain what we’d do and send you a clear quote before we start.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
A DIY attempt does not rule out a professional job. We cut it out and start again.

The process
On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before work begins. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. For a job in Botany, tell us the floor, how the door entry system works and where we can park nearby.
- We start by checking the joint for movement, leaks and the reason it 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.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can
- Clear the area around the work
