How we handle fire rated sealant in Timsbury
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. If you have unsealed gaps where pipes and cables go through a wall and unsealed gaps around fire door frames, we can put it right, on flats & HMOs, plasterboard & masonry and pipe & cable gaps alike.
Work in a small place like Timsbury is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. 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.
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.
Common questions in Timsbury
Is Timsbury in your area for fire rated sealant?
Yes. Our work covers London and the South East, and Timsbury is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing.
Can you help a landlord with a rental near Mottisfont & Dunbridge station?
Yes. We work for landlords and letting agents as well as homeowners. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do you guarantee your work?
Yes. All our work carries our one-year guarantee.
Do you work in flats, HMOs and commercial buildings?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we will plan the work to suit.
How long will you be here?
Most jobs take a few hours for a handful of gaps, and longer for a whole building, including the preparation. We’ll confirm how long when we quote.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Where is Mr Mastic based?
We work from Crawley. We cover Timsbury and the rest of Hampshire, along with the rest of our area.
When something else is needed
We’ll always be straight with you, so here’s what new sealant will not do:
- Doors that are not fire doors in the first place
- Construction that does not provide fire resistance on its own
- Openings too large for sealant, which need batts, boards or another system
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think.
Surfaces we seal

What we’re called out for in Timsbury
Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. Rushed fire stopping is common, especially where it was squeezed in at the end of a project.
The problems people normally mention when they call are:
- Fire stopping disturbed by later work
- New service routes left unsealed after building work
- Unsealed gaps around fire door frames
- Gaps where walls meet ceilings or slabs
If you look after a building such as Stanbridge Earls School, gaps opened by contractors for new cabling are a common finding in schools and offices.
What to look for in a quote
- What the cure time is
- Is VAT in the price?
- Who does the work, and how experienced they are
- How long the guarantee is
Different surfaces, different methods
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.
Door frames
Frame gaps are generally hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size.
What happens on the day
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a few hours for a handful of gaps, and longer for a whole building in most cases. Somewhere like Timsbury needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- We remove any old or unsuitable filler and clean the gap.
- Where the tested detail needs backing or fill, we fit it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
