How it works
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 anything from a few hours to several days, depending on how many gaps there are. Around Alexandria, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- 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.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Locations and products are noted so you have them on file.
Before we arrive
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks

Fire rated sealant for homes and businesses in Alexandria
We don’t assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We work on pipe & cable gaps, linear gaps and service penetrations, and people most often call us about door frames with gaps between frame and wall and sealant items on a fire risk assessment action list.
For holiday lets, guest houses and community buildings in or near Alexandria, the washrooms and kitchens need the same care as any city building, and fire-rated joints should be kept in good order.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

How we quote for fire rated sealant
We quote each job individually. These are the things that affect it:
- The product the joint needs
- Whether there’s mould to deal with
- Working hours on commercial sites
- Whether the work is at height
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. You will know the price before we begin.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Where the job is, and your postcode
- How we’d reach the joints
- The rough size of the job
- The type of property
We quote each job on its own. Simply drop us a line at info@mrmastic.co.uk and describe the job and send pictures if you have them.

Questions from Alexandria
Can you help a landlord with a rental near Alexandria station?
Yes, landlords and agents are among the people we work for. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Are the rules for fire-rated sealant different in Scotland?
Scotland has its own building regulations, the Building (Scotland) Regulations, with their own 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.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Where is Mr Mastic based?
We’re based in Crawley, and we work across South East England, London and Scotland.
How long does fire rated sealant take?
A typical job takes a few hours for a handful of gaps, and longer for a whole building, including preparation and clearing up. We will confirm how long when we quote.
Do you come to Alexandria?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
Is it OK to seal over old sealant?
No. The old sealant always comes out first, so the new sealant bonds properly.
Can you tell me which gaps need fire stopping?
No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.
What the job involves on each surface
Flats and HMOs
Conversions generally leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product and record where they are.
Door frames
Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size.
Commercial buildings in Alexandria
Scotland has its own building regulations, the Building (Scotland) Regulations, with technical handbooks. Fire-rated sealant is installed to the manufacturer’s tested details, though we don’t certify buildings or do fire risk assessments.
If you look after a building such as Vale of Leven Academy, gaps opened by contractors for new cabling are a common finding in schools and offices. For landlords with property near Alexandria station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Community buildings like St Andrew's Parish Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Local landmarks in Alexandria

Why deal with it now?
A quick fill with any sealant to hand is not fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Around Alexandria, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Combining jobs into one visit is normally more efficient than separate visits. We will give you a clear price for the lot.

Landlords, agents and businesses in Alexandria
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Keep pictures of seals that will be hidden
- Include fire stopping when you schedule refits
- Check risers, ceiling voids and cupboards during building checks
- Keep general-purpose foam and caulk away from fire-stopping gaps
Don’t drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Sealing them early helps on every front.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
