About our fire rated sealant in Upper Winchendon
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 new service routes left unsealed after building work and joints picked up in a fire-stopping survey, we can put it right, whatever the surface.
In a village or hamlet like Upper Winchendon, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

When something else is needed
We’ll always be straight with you, so here’s what sealant cannot fix:
- Sign-off of the building, which sits with building control or your assessor
- Walls or floors that weren’t built to resist fire
- Fire risk assessments, which need a qualified assessor
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
Surfaces we seal
- Flats & HMOs
- Pipe & cable gaps
- Service penetrations
- Plasterboard & masonry
- Linear gaps
- Door frames
Different surfaces, different methods
Linear gaps
Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both from the manufacturer’s details.
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.
What fire rated sealant looks like in Upper Winchendon
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
If you look after a church, hall or community building such as Parish Church of St Mary Magdalene, older buildings that have had new heating or wiring often have service gaps worth checking. For landlords with property near Aylesbury Vale Parkway station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Why act early in Upper Winchendon
A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Older cottages and farmhouses around Upper Winchendon can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and send you a clear quote before we start.

Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Will we have a record of what was sealed?
Yes. We note each location and the product that went in so it’s there for the next inspection.
Will you assess my building’s fire safety?
No. Your fire risk assessor, designer or building control decides that. We apply fire-rated sealant to the requirements they set.
Do you do fire sealant around door frames?
Yes. Gaps behind architraves are a common job for us. Doors, seals and closers need a door specialist.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Where is Mr Mastic based?
We are a Crawley-based firm. We work across South East England, London and Scotland.
Signs you need fire rated sealant in Upper Winchendon
Gaps around door frames are easily missed. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.
It’s worth asking for a quote if you see:
- Unsealed gaps around fire door frames
- New service routes left unsealed after building work
- Unsealed gaps where pipes and cables go through a wall
- Ordinary sealant used where a fire-rated product was needed
For site and facilities teams at buildings such as Waddesdon Church of England School, gaps opened by contractors for new cabling are a common finding in schools and offices.
What to look for in a quote
- Whether the sealant suits the joint
- How hidden problems are handled
- Who does the work, and how experienced they are
- Whether they seal over old material or remove it
