Fire rated sealant in Larkfield, done properly
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. 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 are often asked to deal with linear gaps at the head of walls and joints picked up in a fire-stopping survey, across pipe & cable gaps, service penetrations and flats & HMOs.
If you have holiday lets, a converted barn used for business or a community building near Larkfield, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
Your job is guaranteed for a year, as with all our work.

Your questions about fire rated sealant in Larkfield
Do you work for landlords with property near New Hythe station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Do you take on hotel work around Larkfield?
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 you tell me which gaps need fire stopping?
No. That’s for a fire risk assessor, designer or building control. We apply fire-rated sealant to the requirements they set.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Will we have a record of what was sealed?
Yes. We note each location and the product that went in.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Where is Mr Mastic based?
Our base is Crawley. Our area covers South East England, London and Scotland.
What happens on the day
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Somewhere as small as Larkfield, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Finally, we list where we worked and what we used, for your records.
Before we arrive
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints

Work for landlords, hotels and businesses
We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Surface by surface
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. We follow the manufacturer’s tested detail for each.
Flats and HMOs
Working in occupied flats needs some planning. Access to flats and common areas is agreed in advance.
DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Workplaces and buildings in Larkfield
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. Larkfield 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 church, hall or community building such as Church of the Holy Trinity, service openings in its walls need the right fire-rated sealant, as in any building. Schools such as Brookfield Junior School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. Letting a property close to New Hythe station? Then any gap left by new services in shared walls should be closed with a fire-rated product.

What happens if it’s left?
Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own that doesn’t depend on other work. In a small place like Larkfield, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.

What else we do in Larkfield
Honest limits
In fairness, some problems need a different trade:
- A wall that is not a fire-resisting element to begin with
- Problems with the door itself rather than the gap around the frame
- Sign-off of the building, which sits with building control or your assessor
If you’re not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
What we seal
- Pipe & cable gaps
- Door frames
- Linear gaps
- Flats & HMOs
- Service penetrations
- Plasterboard & masonry
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Allow for resealing whenever new services are run
- Keep photos of seals that will be hidden
- Check whether a sealant can be painted before decorating over it
- Check risers, ceiling voids and cupboards during building checks
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. A lot of damaged fire stopping comes from later work.
Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes.
