For landlords and businesses
Letting agents and landlords in Thornhill can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
How we handle bathroom resealing in Thornhill
Mr Mastic has more than 20 years’ experience of sealant work, and our applicators reseal bathrooms and kitchens across Thornhill. We’re fully insured ARBOMaster approved applicators, and every job carries our 12-month guarantee. We’re often asked to deal with lumpy, uneven sealant from a DIY attempt and leaking joints on a shower screen, on sinks & splashbacks, shower trays & enclosures and baths.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses. Older buildings can move a little, and that shows first in cracked grout and split sealant.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

FAQs for Thornhill
Do you work in hotels near Thornhill?
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.
Do you cover Thornhill for bathroom resealing?
Yes. Our work covers the whole of Scotland, and Thornhill is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
What colours of sealant can you use?
You’re not limited to white: clear, white and colours chosen to suit the room. We will talk it through when we quote.
How long will the resealing take?
It depends on how many joints there are and how much old sealant has to come out. For most single baths or showers, allow a couple of hours.
How much does bathroom resealing cost in Thornhill?
Size, access and the old material all affect the cost. Call for a quick quote.
When can I use the bath or shower again?
We give you the cure time before we leave, and it’s generally around 24 hours. Getting it wet too early can spoil the new joint.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
What we’re called out for in Thornhill
No sealant lasts indefinitely. Every shower, every splash and every wipe with a cleaner slowly wear it down, and how long it lasts comes down to use, cleaning and ventilation.
Common reasons people contact us are:
- Mouldy sealant that has gone black
- Gaps between the worktop and the wall
- Gaps where the bath or tray has moved
- Smears of silicone across the tiles
Managing a site like Wallace Hall Academy? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

How the job changes by surface
Wet rooms
Not every wet room leak is a sealant problem. We check the joints and say so if the fault looks to be elsewhere.
Sinks & splashbacks
Water getting under the rim of an inset sink can soak the worktop. We reseal the visible edge of the sink where it has failed.
Looking after it afterwards
Aftercare is simple:
- Run the extractor fan during and after every shower
- Don’t let bottles sit on the bead
- Dry worktop joints after washing up
- Never pick at the silicone with a blade
Wipe up standing water along the worktop joint and keep hot pans away from the silicone. The drier the joint stays, the longer it lasts.
There’s no need to wait for a full refurbishment. Sealant is a maintenance item, like the paint on a window frame, and renewing it as soon as it fails protects everything around it.
How the visit works
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a couple of hours for a single bath or shower. Outdoor work around Thornhill depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We cover the area around the joints we are working on.
- We cut away the old sealant and clean off what’s left.
- Mould is treated, then the joint is left to dry thoroughly.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- The joint is finished neatly and we explain when it can get wet.
How to prepare
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions

Related advice
Bathrooms and kitchens in Thornhill
In Scotland, private landlords have to 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. 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.
Around Thornhill, as everywhere, bathroom resealing is only as good as the preparation behind it.

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
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.
