Fire rated sealant for homes and businesses in Wonersh
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. Each gap is sealed to the product maker’s tested detail for its size and substrate, and we can record what went where. If you have fire stopping disturbed by later work and standard silicone or caulk in a fire-stopping gap, we can put it right, whatever the surface.
For holiday lets, converted business premises or a community building near Wonersh, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
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.

What we do, step by step
At the end, we look at the finished work together and tell you how long to leave it. The visit itself usually takes anything from a few hours to several days, depending on how many gaps there are, depending on how much there is to do. In a small place like Wonersh, access is generally the main thing to plan. 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.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your files.
Preparing for the visit
- Mention if the joints have been sealed before
- Keep children and pets away from the work area
- Tell us if parking is tricky

What fire rated sealant looks like in Wonersh
There are hotels and other places to stay in and around Wonersh. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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.
Managing a site like Bramley CofE Aided Infant School and Nursery? Then fire-stopping around service openings should be restored whenever new services go in. For buildings such as Wonersh United Reformed Church, older buildings that have had new heating or wiring often have service gaps worth checking.

Signs you need fire rated sealant in Wonersh
Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.
It’s worth asking for a quote if you see:
- Fire stopping disturbed by later work
- Gaps where walls meet ceilings or slabs
- Gaps flagged on a fire risk assessment
- Ordinary sealant used where a fire-rated product was needed
For landlords with property near Chilworth station, any gap left by new services in shared walls should be closed with a fire-rated product.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Wonersh questions
Is Wonersh within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Chilworth station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Can you do several jobs on one visit?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few photos.
Can you tell me how many minutes the seal will last?
That isn’t something we state or certify. The requirement comes from your assessor, designer or building control, and we fit a product whose tested details meet it.
How long will you be here?
It depends on the size of the job, but as a guide it takes from a few hours to a few days, depending on the number of gaps and the access. We will give you a better idea when we quote.
Is standard sealant good enough for a fire gap?
No. It might close the gap, but it is not a fire-rated seal. Use a product tested for that gap and service, or ask us to do it.
When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Certifying a building or signing off its fire safety
- Assessing a building’s fire safety
- Construction that doesn’t provide fire resistance on its own
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before booking.
What we seal
- Door frames
- Flats & HMOs
- Linear gaps
- Service penetrations
- Plasterboard & masonry
- Pipe & cable gaps
Why it’s worth doing now in Wonersh
For some gaps, sealant is not the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. We will say so if a gap needs something other than sealant. Older cottages and farmhouses around Wonersh can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why choose Mr Mastic in Wonersh
- Anti-fungal silicone where joints get wet
- A 12-month guarantee on all work
- Trusted Arbo and Everbuild sealants
- ARBOMaster approved applicator

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Take photos of fire stopping before ceilings or boxing go back
- Never patch a fire seal with standard sealant
- Get damaged fire seals looked at promptly
- Ask which product was used before you paint
File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.
An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Sealing them early helps on every front.
