About our bathroom resealing in Biggar
It isn’t only bathrooms. Worktop upstands, sink edges and splashback joints get wet every single day, and water that gets into the back edge of a worktop can swell the board. We reseal them with a kitchen-suitable silicone, matched to the worktop where it’s on show. If you have mouldy sealant that has gone black and shrunken sealant along the back of a worktop, we can put it right, whatever the surface.
For a place like Biggar, 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. The journey and access are simply planned in advance.
Big or small, you get the same 12-month guarantee.

Aftercare tips
To keep the joints looking good and working properly:
- Give the silicone its full cure time
- Do not leave water standing on kitchen joints
- Run the extractor fan during and after every shower
- Keep scourers and sharp tools away from the bead
Treat the new bead gently when you clean: a mild bathroom cleaner and a soft cloth is enough. Scourers and blades can nick the surface, because a damaged bead gives mould a foothold.
Each shower pushes a little more water through a failed joint. Left alone, it soaks into the floor, the wall behind the tiles or the ceiling below. Resealing early stops it.

Why it’s worth doing now in Biggar
Tired sealant is not a reason to replace a bath or shower. Replacing the joint is usually all it takes. If we find a deeper problem, you’ll hear it from us. In a place like Biggar, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll go through it with you.

Common problems we fix in Biggar
Older sealant shrinks and hardens. Along worktops it tends to pull back from the wall, leaving a thin gap where water and food collect. Hot pans and harsh cleaners do not help.
If you can see any of these, it’s time to have the joints looked at:
- Water escaping at the shower enclosure
- Sealant that has split, shrunk or peeled away
- Smears of silicone across the tiles
- Gaps between the worktop and the wall
In the older streets around Biggar Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Common questions in Biggar
Can you do bathroom resealing in Biggar?
Yes, Biggar is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
Do you work for hotels and guest houses in Biggar?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Is the work guaranteed?
Yes, for 12 months. Good ventilation and gentle cleaning help it last.
Can mouldy silicone be sorted out?
Yes, we can. We strip the bead, treat the joint and lay new anti-fungal silicone.
How long does it take to reseal a bath or shower?
One bath or shower is around two hours’ work, including cutting out the old sealant. A whole bathroom plus the kitchen may take most of the day.
Is white the only colour available?
There’s a choice: clear, white and colours chosen to suit the room. We will talk it through when we quote.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
How long before the new sealant can get wet?
Silicone is touch-dry quite quickly, but it takes longer to cure. Keep water off it for around 24 hours, or as long as we advise for that product.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
A careful DIYer can reseal a simple joint, 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.
Biggar homes and their sealant
Biggar has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room. Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. But mould still grows into sealant and grout in a room that does not dry out.
If you look after a building such as Biggar High 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.

Basins & vanity units
A vanity top has a joint along the wall and sometimes at the sides. If water gets in, the cabinet underneath can swell, so a neat, continuous bead matters.
Wet rooms
Not every wet room leak is a sealant problem. We reseal the joints and will tell you if the water seems to be coming from somewhere else.
