Fire rated sealant for homes and businesses in Mongewell
We can work through a building room by room or floor by floor, noting the locations and products as we go. That record is useful for your files and for whoever looks at the building next. Typical jobs include damaged fire sealant left by other trades and sealant items on a fire risk assessment action list, on linear gaps, service penetrations and flats & HMOs.
For holiday lets, converted business premises or a community building near Mongewell, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

What the job involves on each surface
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall.
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. Each one is sealed to the product’s tested detail.
What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of gaps, and longer for a whole building. Somewhere like Mongewell needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start with the survey or action list, checking the size and surfaces of every gap.
- We remove any old or unsuitable filler and clean the gap.
- We put in whatever backing or fill the product detail specifies.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- We record the locations and products used for your records.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can
Ask for a quote
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Advice
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Check whether a sealant can be painted before decorating over it
- Check risers, ceiling voids and cupboards during building checks
- Allow for resealing whenever new services are run
- Keep the record of products and locations with your fire safety documents
Any fire seal that is cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.

Work for landlords, hotels and businesses
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Why act early in Mongewell
For some gaps, sealant is not the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap isn’t suitable for sealant, we’ll tell you. In a small place like Mongewell, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts.
Why choose Mr Mastic in Mongewell
- Anti-fungal silicone where joints get wet
- Full insurance on every job

Fire rated sealant in Mongewell: local notes
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.
For buildings such as St Mary's Church, older buildings that have had new heating or wiring often have service gaps worth checking. If you look after a building such as Crowmarsh Gifford Church of England School, fire-stopping around service openings should be restored whenever new services go in. If you let a flat or house near Cholsey station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Mongewell questions
Is Mongewell within the area you cover?
Yes, Mongewell is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

How long does the job take?
It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on how many gaps there are. We’ll tell you when we quote.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Can you tell me how many minutes the seal will last?
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.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Can you match the sealant colour?
Usually, yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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.
