How we handle fire rated sealant in Crosslet
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. We work on flats & HMOs, service penetrations and door frames, and common reasons people get in touch are seals cut through by electricians, plumbers or data installers and gaps where walls meet ceilings or slabs.
In a smaller place like Crosslet, commercial jobs are more likely to be a hotel, guest house, school, surgery or community hall than an office block. All of them have washrooms, kitchens and fire-rated joints that need looking after.
You get a 12-month guarantee, the same in Crosslet as everywhere else we work.

Workplaces and buildings in Crosslet
If you run a hotel, guest house or holiday let in a coastal place like Crosslet, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Scotland has its own building regulations, the Building (Scotland) Regulations, with technical handbooks. We install fire-rated sealant to the product’s tested details, though we do not certify buildings or do fire risk assessments.
If you look after a building such as Dumbarton Academy, gaps opened by contractors for new cabling are a common finding in schools and offices.

What affects the quote in Crosslet
There’s no set price list. The quote depends on:
- Whether there’s mould to deal with
- Working hours on commercial sites
- How many areas need sealing
- The size of the job
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. 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.
What to tell us for a quote
When you call or email, these details help:

- A few photos by email, if you can
- Access, such as stairs, a lift or height

Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for a handful of gaps, and longer for a whole building. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your records.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in

When to call us in Crosslet
Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.
Most people get in touch after spotting one of these:
- Open holes round services passing through fire walls
- Joints picked up in a fire-stopping survey
- Standard silicone or caulk in a fire-stopping gap
- Cracked or shrunken fire-rated sealant
For landlords with property near Dumbarton East station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
Questions to ask before you book
- How much experience the applicator has
- What happens if the job turns out different
- Are they insured?

Different surfaces, different methods
Flats and HMOs
Converted houses often have gaps around old and new services. We seal the ones on your specification with a tested product and the locations noted.
Linear gaps
Gaps along the top of partitions are easy to miss above a ceiling. We work along the whole run so there are no open sections left.
Questions from Crosslet
Will you come out to Crosslet?
Yes. Crosslet is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
How do Scotland’s building regulations apply to fire-rated sealant in Crosslet?
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 carry out fire risk assessments, so your fire risk assessor or building control will advise on what’s needed.
Can ordinary silicone be used in a fire-stopping gap?
No. It looks sealed but will not perform as fire stopping. A tested fire-rated product is needed, or ask us to do it.
Do you offer different sealant colours?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Can you tell me which gaps need fire stopping?
No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
What happens if it’s left?
Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job. Around Crosslet, water from a failed joint in an older stone home can soak into timber and plaster.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start.
