About our fire rated sealant in Alkerton
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. If you have unsealed gaps around fire door frames and open holes round services passing through fire walls, we can help, whatever the surface.
For a small place like Alkerton, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
You get a one-year guarantee, the same in Alkerton as everywhere else we work.

Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Leave it or put it right?
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. Older cottages and farmhouses around Alkerton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
Why choose Mr Mastic in Alkerton

The process
There is not much for you to do on the day. Show us the job and we will take it from there. The work itself takes from a few hours to a few days, depending on the number of gaps and the access from start to finish. Somewhere as small as Alkerton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your records.
How to prepare
- Tell us if parking is tricky
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can
Getting a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we will take it from there.
Advice
How the job changes by surface
Masonry and concrete
Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it before applying the sealant.
Service penetrations
Service penetrations are where new gaps often appear. We clean out what’s there and reseal to the right depth over any backing the detail calls for.
Fire rated sealant around Alkerton
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, which is often where open fire-stopping gaps are first noticed. We work to the specification you’re given, installing the product to its tested details.
If you look after a building such as Shenington Church of England Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. If you look after a church, hall or community building such as Church of St Michael, service openings in its walls need the right fire-rated sealant, as in any building.

What affects the quote in Alkerton
Some jobs are bigger than they look, and some smaller. The main factors:
- How easy the joints are to reach
- The amount of work
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
Asking for a quote
What to tell us when you ask for a quote:
- Any previous sealing or DIY work
- The type of property
- Photos by email, if that’s easy
- The address or postcode of the job
If you are in Alkerton and need fire rated sealant, call 0345 464 0079 or email us. Tell us what the problem is and where, and we will agree the price before any work begins.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Your questions about fire rated sealant in Alkerton
Is there a guarantee on fire rated sealant in Alkerton?
All our work, in Alkerton and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Is Alkerton in your area for fire rated sealant?
Yes. We work across London and the South East, and Alkerton is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Can you match the sealant colour?
In most cases you can choose. We will tell you which colours the right product comes in.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you certify the fire stopping?
We don’t certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and list the locations and products for you.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
How long will you be here?
That depends on the amount of work, but most jobs take a few hours for a handful of gaps, and longer for a whole building. We will tell you when we quote.
Honest limits
It helps to know what we can’t do:
- Deciding what fire stopping a building needs
- Openings too large for sealant, which need batts, boards or another system
- Issuing a fire rating or certificate for a building
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before you book.
