Fire rated sealant in Bagmore
Fire stopping only performs as intended if it’s done to the detail: the right depth, the right backing and the right product for the substrate. That detail is what we take care over. If you have fire stopping disturbed by later work and gaps flagged on a fire risk assessment, we can put it right.
Somewhere as small as Bagmore, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

When it isn’t the sealant
We will not take on work that will not last, so these are the limits:
- Assessing a building’s fire safety
- Big openings where sealant alone isn’t the tested solution
- Fire doors that need new seals, closers or hardware
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.
Surfaces we seal
- Service penetrations
- Pipe & cable gaps
- Door frames
- Flats & HMOs
- Linear gaps
- Plasterboard & masonry
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How to look after the new joints
After the cure time, these simple habits help:
- Keep the record of products and locations with your fire safety documents
- Include hidden areas like risers in routine checks
- Keep photos of seals that will be hidden
- Allow for resealing whenever new services are run
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint, so ask us which we used.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is normally a straightforward job.
Commercial buildings in Bagmore
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Letting a property close to Alton station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a church, hall or community building such as Church of St. Mary, older buildings that have had new heating or wiring often have service gaps worth checking.

Questions from Bagmore
Is Bagmore in your area for fire rated sealant?
Yes. We work across London and the South East, and Bagmore is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Will you come out to Bagmore?
Yes. Bagmore is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Are you insured?
Yes. Mr Mastic is fully insured.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
What fire rating will the seal have?
We don’t issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves; we install to those details and record what we did.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Is intumescent sealant the same as fire-rated sealant?
Intumescent means it swells when heated. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.
What affects the quote in Bagmore
We quote each job individually. This is what makes a difference:
- Mould in or behind the old joints
- Access and height
- Whether old sealant or filler has to be cut out
- How many areas need sealing
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
To make quoting easier, let us know:
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
- The problem you’ve noticed
- Where the job is, and your postcode

How it works
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before we start. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Somewhere like Bagmore needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- We apply and tool the sealant to the product’s tested detail.
- We record what was done and flag anything that needs a different system.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Mention any tricky access
- Clear items away from the joints we’re working on

Related advice
Different surfaces, different methods
Linear gaps
Linear gaps run along the head of walls, at floor edges and between panels. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. We follow the manufacturer’s tested detail for each.
Why act early in Bagmore
If an assessor has flagged gaps, it makes sense to close them before the next review. Getting them done and written up means you can show the action was taken. Where a wall is exposed, as many are in small places like Bagmore, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.
