Remedial sealant in Royston, done properly
Water on the floor does not always mean failed silicone. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. When the fault is elsewhere, we say so instead of resealing for the sake of it. We are often asked to deal with a shower that leaks however often it’s resealed and torn expansion joints, on expansion joints, mouldy bath & shower sealant and shrunken worktop sealant.
Royston is in one of Scotland’s four big cities, where many tenement bathrooms were fitted into rooms that weren’t built for them. Space is tight and ventilation can be poor, which is hard on sealant and grout.
Each job carries a 12-month guarantee, whatever its size.

Royston: your questions answered
I let a flat near Barnhill station. Can you help?
Yes, landlords and agents are among the people we work for. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
Could a leaking bath seal in my Royston flat reach the neighbours 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.
Can you take off two layers of silicone?
Yes. We cut out all the layers and clean off the film, then the joint is resealed once.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
Can I choose the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in and agree one before work begins.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do you come to Royston?
We do. Royston is part of the area we cover, and the service is the same as everywhere else.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, 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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Common problems we fix in Royston
One of the commonest remedial jobs is sealant on top of sealant. Silicone does not bond to silicone, so the new layer peels, and damp and mould settle between them.
It’s worth asking for a quote if you see:
- Movement joints that have split or pulled away
- Gaps opening along the back of the worktop
- Thick, messy sealant smeared over tiles
- Repeat leaks from the same joint
For site and facilities teams at buildings such as St. Roch's Secondary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

How to look after the new joints
So the new joints stay in good condition:
- Clean sealant with mild products only
- Keep an eye on the ceiling below the bathroom
- Act on a lifting corner straight away
- Never seal over old silicone
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant cannot hold back a problem underneath.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.

Remedial sealant in Royston: local notes
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. Glasgow has a lot of sandstone tenements, where most bathrooms sit above another flat.
Homes close to Townhead and Blochairn Parish Church include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. For landlords with property near Barnhill station, a joint that keeps failing is best fixed properly while the property is empty.
