Why act early in Lewiston
Sealant isn’t the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we’ll tell you. In a place like Lewiston, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.
Why choose Mr Mastic in Lewiston

About our fire rated sealant in Lewiston
We often work from an action list drawn up by a fire risk assessor on buildings across Lewiston. Send us the list or the survey and we will quote for the fire-rated sealant work on it. If you have gaps left after a refit or conversion and linear gaps at the head of walls, we can put it right, on plasterboard & masonry, flats & HMOs and pipe & cable gaps alike.
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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

How the job changes by surface
Plasterboard walls
We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. The sealant is chosen for what passes through and how wide the gap is.
Signs you need fire rated sealant in Lewiston
Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
Any of these means the joints need attention:
- Sealant items on a fire risk assessment action list
- Holes left by a change of layout
- Door frames with gaps between frame and wall
- Seals cut through by electricians, plumbers or data installers
Community buildings like Kilmore Parish Church of Scotland are part of the picture too: gaps around pipes and cables are worth checking after any building work there.
Questions to ask before booking
- Whether they seal over old material or remove it
- Is VAT in the price?
- How hidden problems are handled
- How the colour is chosen
The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take a few hours for a handful of gaps, and longer for a whole building. For a place like Lewiston, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Before we arrive
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work

What affects the quote in Lewiston
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
- Any mould that needs treating
- The size of the job
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What to tell us for a quote
What to tell us when you ask for a quote:
- Pictures of the joints, sent by email
- The address or postcode of the job
- The problem you’ve noticed
- If it’s domestic, commercial or a hotel
If you are in Lewiston and need fire rated sealant, email us at info@mrmastic.co.uk. Tell us what the problem is and where, and you’ll get a clear quote before any work starts.
What fire rated sealant looks like in Lewiston
There are hotels and other places to stay in and around Lewiston. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. Scotland has its own building regulations, the Building (Scotland) Regulations, with technical handbooks. Fire-rated sealant is installed to the manufacturer’s tested details; we do not certify buildings or carry out fire risk assessments.
Managing a site like Glen Urquhart High School? Then fire-stopping around service openings should be restored whenever new services go in.

What we can’t put right
We’ll always be straight with you, so here’s what new sealant won’t do:
- Fire doors that need new seals, closers or hardware
- Sign-off of the building, which sits with building control or your assessor
- Openings too large for sealant, which need batts, boards or another system
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before you book.
What we seal
- Linear gaps
- Door frames
- Flats & HMOs
- Pipe & cable gaps
- Plasterboard & masonry
- Service penetrations
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Questions from Lewiston
Are the rules for fire-rated sealant different in Scotland?
Building work in Scotland comes under the Building (Scotland) Regulations and their technical handbooks. Fire-rated sealant has to go in to the product’s tested details, and we follow them. We don’t certify buildings or do fire risk assessments; your assessor or building control can tell you what’s required.
Will you come out to Lewiston?
Yes. Lewiston 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.
Do you seal gaps around fire door frames?
Yes. The joint between frame and wall is sealed with a fire-rated sealant, to the product’s details. The door, its seals and closer are for a door specialist.
What fire rating will the seal have?
That is not something we state or certify. Your specification sets the requirement, and we apply a product tested for it.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Do you provide details of the products used?
Yes. You get a list of where we worked and what we used.
Do you carry out fire risk assessments?
No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.
How long does the job take?
It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on how many gaps there are. We will tell you when we quote.
