Fort William questions
Do you work for landlords with property near Fort William station?
Yes, landlords and agents are among the people we work for. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Do you take on hotel work around Fort William?
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.
Can I choose the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Where do you work from?
We are based in Crawley, and we work across South East England, London and Scotland.
Fire rated sealant for homes and businesses in Fort William
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate. If you’re dealing with fire seals that have cracked with movement and gaps filled with a product that isn’t fire-rated, we can put it right.
Commercial work around smaller Scottish places tends to mean hotels, guest houses, schools and halls rather than offices. All of them have washrooms, kitchens and fire-rated joints that need looking after.
Whatever the size of the job, it’s backed by our 12-month guarantee.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
What happens if it’s left?
Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing once someone inspects it. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
Why us?
- We are fully insured
- Homes, businesses and hotels
- Neat joints and a tidy finish
- Anti-fungal silicone where joints get wet
What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours for a handful of gaps, and longer for a whole building. Outside jobs in Fort William need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We start with the survey or action list, checking the size and surfaces of every gap.
- We remove any old or unsuitable filler and clean the gap.
- Backing or fill is fitted where the product’s tested detail calls for it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Locations and products are noted so you have them on file.
How to prepare
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property
- Tell us about any water getting in
How to get a quote
We do not publish a price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To arrange one, send an email to info@mrmastic.co.uk.

- Fire stopping disturbed by later work
- Gaps where walls meet ceilings or slabs
- Open gaps behind door architraves
- Gaps around pipes and cables through fire-resisting walls

Fire rated sealant around Fort William
If you run a hotel, guest house or holiday let in a coastal place like Fort William, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Fort William has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.
If you look after a building such as Lochaber High School, service openings in fire-resisting walls need checking after any refurbishment. Community buildings like St Andrew's Episcopal Church are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Check whether a sealant can be painted before decorating over it
- Report cracked or damaged seals as soon as you notice them
- Keep general-purpose foam and caulk away from fire-stopping gaps
- File the fire-stopping record where your assessor can find it
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and have them put right.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the job gets bigger.
