Fire rated sealant in Holt End
We do not 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. Common call-outs are for old fire sealant that has split or come away and gaps left after a refit or conversion, on door frames, flats & HMOs and pipe & cable gaps.
For holiday lets, converted business premises or a community building near Holt End, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

What the job involves on each surface
Door frames
A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.
Plasterboard walls
We check that the board around the gap is sound. Loose material is removed so the sealant has a firm edge.
Common problems we fix in Holt End
Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. Rushed fire stopping is common.
Most people get in touch when they notice something like this:
- Cracked or shrunken fire-rated sealant
- New service routes left unsealed after building work
- Door frames with gaps between frame and wall
- Open holes round services passing through fire walls
Letting a property close to Alton station? Then any gap left by new services in shared walls should be closed with a fire-rated product.
Questions to ask before you book
- What guarantee comes with the work
- Who does the work, and how experienced they are
- Whether VAT is included
- Whether all the old sealant comes out first
What happens if it’s left?
Sealant is not the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap is not suitable for sealant, we will tell you. Around Holt End, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and give you a clear quote before we start.

The process
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Holt End, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your files.
Before we arrive
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before

Holt End: your questions answered
Will you come out to Holt End?

Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in.
Can you work in occupied buildings?
Yes. We regularly work in flats, HMOs, schools and offices while they’re in use, with access planned around residents or staff. Out-of-hours work can be arranged where it’s needed.
Can I use normal mastic around a pipe through a fire wall?
No. It might close the gap, but it isn’t a fire-rated seal. Use a product tested for that gap and service, or ask us to do it.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.

Fire rated sealant around Holt End
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Managing a site like St Mary's Bentworth Church of England Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices. Community buildings like St. Mary's Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
