About our fire rated sealant in White Waltham
Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. If you are dealing with ordinary sealant used where a fire-rated product was needed and gaps where walls meet ceilings or slabs, we can put it right, whatever the surface.
Somewhere as small as White Waltham, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
We stand behind the work with a 12-month guarantee.

Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Workplaces and buildings in White Waltham
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 are given, installing the product to its tested details.
Rented homes near Maidenhead station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For buildings such as Church of St Mary, gaps around pipes and cables are worth checking after any building work there.

- Openings too large for sealant, which need batts, boards or another system
- Doors that are not fire doors in the first place
- Construction that does not provide fire resistance on its own
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
What we seal

Aftercare tips
After the cure time, these simple habits help:
- Allow for resealing whenever new services are run
- File the fire-stopping record where your assessor can find it
- Photograph sealed gaps before they’re covered up
- Check whether a sealant can be painted before decorating over it
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.
If a fire risk assessment has flagged a gap, don’t leave it for the next one. Have it sealed, then keep the record so you can show it was dealt with.
Different surfaces, different methods
Masonry and concrete
Holes through concrete and block are rarely neat. We measure the gap at its widest point to make sure it suits the product.
Plasterboard walls
Plasterboard partitions are common in flats, offices and conversions. The sealant has to be one tested in plasterboard for each gap size.
What we do, step by step
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like White Waltham, the journey is planned in advance: 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 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.
- Any non-fire-rated filler is removed 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
- Let us know about stairs, lifts or work at height
- Mention any sign-in or site rules at work premises
- Mention any leaks or damp you’ve noticed

White Waltham questions
Is White Waltham in your area for fire rated sealant?
Yes. We work across London and the South East, and White Waltham is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.
Will you come out to White Waltham?
Yes. White Waltham 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.
Where is Mr Mastic based?

Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Is intumescent sealant the same as fire-rated sealant?
Intumescent means it swells when heated. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Can you tell me which gaps need fire stopping?
No. We follow the requirements from your assessor, designer or building control.
Do you guarantee your work?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we’ll sort it.

When to call us in White Waltham
A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
Any of these means the joints need attention:
- Linear gaps at the head of walls
- Joints picked up in a fire-stopping survey
- New service routes left unsealed after building work
- Open gaps behind door architraves
Schools such as White Waltham CofE Academy are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.
