Commercial sealant for homes and businesses in Dunbar
Commercial work is planned around the building, not the other way round. Rooms can be done one at a time, floor by floor or in batches, and early starts or out-of-hours working can be arranged where it helps. We work on office washrooms & kitchens, welfare facilities and retail & leisure sites, and common reasons people get in touch are washrooms that need sorting before an inspection and black, stained silicone in guest bathrooms.
For a place like Dunbar, the journey and timings are planned in advance, so the job can fit around guests, residents or opening hours where possible.
We stand behind the work with a 12-month guarantee.

Different surfaces, different methods
Student & care accommodation
Care homes need careful planning around residents, with each bathroom handed back with its cure time.
Welfare facilities
Staff welfare areas are needed every shift. Work can be split into sections so some facilities stay open.
Aftercare tips
So the new joints stay in good condition:
- Add sealant to your planned maintenance checks
- Schedule work around occupancy
- Note the date each area was done
- Pass on the cure time to whoever cleans the rooms
Squeegees in guest and staff showers help: walls and trays dry faster, and so does the sealant.
Black sealant in a staff washroom or guest bathroom draws complaints. Left long enough, it spreads through the bead, so the fix is replacement.
What commercial sealant looks like in Dunbar
If you run a hotel, guest house or holiday let in a coastal place like Dunbar, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. In Scotland, private landlords have to meet the Repairing Standard, so landlords with several properties often need sealant work across them all.
If you look after a church, hall or community building such as Abbey Church of Scotland, halls and community kitchens see heavy use, and their sealant shows it. If you let a flat or house near Dunbar station, several rental properties can be resealed on one programme.

How it works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a single washroom, longer for a whole building. For a place like Dunbar, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First we visit and agree the scope, the sequence and the working hours.
- Room by room, we protect the area and remove all the old sealant.
- Joints are cleaned, treated for mould and dried.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
- We check every room and give its cure time for housekeeping.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can
- Mention any parking rules near the property

Related advice
Leave it or put it right?
Replacing a whole washroom takes time, money and several trades. If the fittings are in good order, new sealant is often all it needs. We’ll tell you if we find anything that needs another trade. In a place like Dunbar, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, 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.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
When it isn’t the sealant
Before booking, it’s worth knowing the limits too:
- A shower tray, bath or basin that’s cracked or broken
- Failed tanking or loose tiles behind the sealant
- A broken extractor fan behind the mould problem
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before booking.

Dunbar: your questions answered
Do you work in hotels near Dunbar?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
I let a flat near Dunbar station. Can you help?
Yes, we work for landlords and letting agents. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Can you work outside opening hours?
In many cases. Tell us your opening hours and quiet times, and we will see what can be arranged.
Where are you based?
Our base is Crawley. We work across South East England, London and Scotland.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
How long do rooms need to be out of use?
Follow the cure time we give you, which is usually around 24 hours. Planning the order of rooms keeps that downtime manageable.
What affects the cost of commercial sealant
The price is agreed before any work begins. It’s based on:
- Any mould that needs treating
- How many areas need sealing
- The type of sealant required
- The size of the job
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What we need to know
To make quoting easier, please include:
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- If someone has resealed it before
