How we handle commercial sealant in Duns
Wet areas get anti-fungal sanitary silicone, and kitchens get a food-safe product where it’s needed. We use sealants from Arbo and Everbuild, applied by ARBOMaster approved applicators. If you’re dealing with tired sealant in let properties and too many rooms to reseal without closing the building, we can put it right, whatever the surface.
For holiday lets, guest houses and community buildings in or near Duns, the washrooms and kitchens need the same care as any city building, and fire-rated joints should be kept in good order.
Each job carries a 12-month guarantee.

FAQs for Duns
Do you work in hotels near Duns?
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 Duns within the area you cover?
Yes. Duns is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
What should I tell you?
A short description and the location. If we need more, we will ask.
Where are you based?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Is there a guarantee?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
How soon can a room be used after resealing?
Follow the cure time we give you, which is normally around 24 hours. A room-by-room programme keeps only a few rooms out at once.
What the job involves on each surface
Hotel bathrooms
We work through hotel rooms in agreed batches, so most rooms stay available. Each room is handed back with its cure time for housekeeping.
Office washrooms & kitchens
A row of basins on a vanity top has a long joint that collects water. We renew it in one tidy, continuous bead.
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Do not leave a failed joint until the next refurbishment
- Note the date each area was done
- Tell cleaning staff when each room can be used
- Put a squeegee in each shower
Include sealant in routine room inspections. A quick look at each bathroom when rooms are checked spots problems early.
It’s easier to plan a programme than to react to failures. Rooms can be scheduled around occupancy and staff, instead of rooms closing without warning.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed 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.
Signs you need commercial sealant in Duns
In office kitchens and tea points, joints are wet and wiped all day, and grease and cleaning sprays break down sealant. The worktop and sink edges normally fail first.
Keep an eye out for any of the following:
- Tired sealant in let properties
- Tired sealant ahead of a health and safety audit
- Leaks from showers into rooms or ceilings below
- Mouldy washroom sealant that staff and guests notice
For buildings such as Old Parish Church, any kitchen and washrooms need the same sealant care as any other building.
Questions to ask before you book
- Whether they’re fully insured
- Which sealant they’ll use, and why
- How hidden problems are handled
- How the surfaces are prepared before sealing

If you’re in Duns and need commercial sealant, drop us a line at info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.
Why act early in Duns
Sealing over the old bead can seem the fastest option, but silicone does not bond to silicone, so it lifts. Doing it properly once is less disruptive than doing it badly twice. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, drop us a line at info@mrmastic.co.uk and we’ll give you an honest view and a quote.
Why book with us
- White, clear, grey or another colour, product permitting
- Trusted Arbo and Everbuild sealants
- Colour agreed with you before any work starts
- Anti-fungal silicone where joints get wet

What we do, step by step

- We agree when we’ll work, with early or out-of-hours slots where they can be arranged.
- Areas are protected and the failed sealant removed.
- Once dry, every joint is resealed and tooled.
- Housekeeping or site staff are told when each area can be used.
How to prepare
- Tell us about any water getting in
- Where the joints are inside, avoid wetting them before we arrive
