Fire-stopping gaps in Cookham Dean need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.

Fire rated sealant for homes and businesses in Cookham Dean
Ordinary silicone or decorators’ caulk in a fire-stopping gap isn’t a fire-rated seal. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. Common call-outs are for unsealed gaps around fire door frames and linear gaps at the head of walls, across service penetrations, pipe & cable gaps and door frames.
If you have holiday lets, a converted barn used for business or a community building near Cookham Dean, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Every job is covered by our 12-month guarantee, wherever you are in Windsor and Maidenhead.

When to call us in Cookham Dean
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It looks sealed, but it isn’t fire-rated.
Signs it’s time to call us include:
- Gaps around pipes and cables through fire-resisting walls
- Joints picked up in a fire-stopping survey
- Gaps left after a refit or conversion
- Cracked or shrunken fire-rated sealant
Managing a site like Cookham Dean CofE Primary School? Then fire-stopping around service openings should be restored whenever new services go in.

How the job changes by surface
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. We seal it with a product tested for that service and gap size.
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Gaps that are too big for sealant alone need a different detail.
Common questions in Cookham Dean
Do you work for landlords with property near Cookham station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Will you come out to Cookham Dean?
Yes. Cookham Dean is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you tell me which gaps need fire stopping?
No. We work from the specification you give us, and apply each product to its tested details.
What does intumescent mean?
An intumescent sealant expands when it gets hot. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Where is Mr Mastic based?
We are a Crawley-based firm. We work across South East England, London and Scotland.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

Yes. Just list everything you need and you’ll get one quote.
Fire rated sealant around Cookham Dean
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. There are hotels and other places to stay in and around Cookham Dean. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
Letting a property close to Cookham station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Photograph sealed gaps before they’re covered up
- Flag any open gap you spot round a pipe or cable
- Tell trades working in the building that fire seals must be put back
- Include fire stopping when you schedule refits
Tell other trades that the gaps have been sealed, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Sealing them early helps on every front.
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It usually takes a few hours for a handful of gaps, and longer for a whole building. In a small place like Cookham Dean, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work
