How the job changes by surface
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. The gap is cleaned of dust first so the seal has something sound to bond to.
Door frames
Frame gaps are usually hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.
How we handle fire rated sealant in Merston
We often work from an action list drawn up by a fire risk assessor on buildings across Merston. If you share the list, we can quote for the gaps that need fire-rated sealant. If you have gaps where walls meet ceilings or slabs and open gaps behind door architraves, we can put it right, on linear gaps, service penetrations and plasterboard & masonry alike.
For holiday lets, converted business premises or a community building near Merston, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
All our work comes with our one-year guarantee, wherever you are in West Sussex.

Common problems we fix in Merston
Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.

- Open joints along the top of partitions
- Old fire sealant that has split or come away
- Gaps flagged on a fire risk assessment
- Seals cut through by electricians, plumbers or data installers

Questions from Merston
Do you cover smaller places like Merston?
Yes. Merston 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 do fire rated sealant in Merston?
Yes. Our work covers London and the South East, and Merston is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Do you provide details of the products used?
Yes. You get a list of where we worked and what we used.
How long will you be here?
As a guide, most jobs take a few hours for a handful of gaps, and longer for a whole building. Bigger jobs take longer, and we will say how long yours will take.
What do you need from me for a quote?
Let us know what needs doing and where. We’ll ask anything else we need to know.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
What does intumescent mean?
An intumescent sealant expands when it gets hot to help seal the gap. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Will you assess my building’s fire safety?
No. We work from the specification you give us and install to the manufacturer’s details.
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 tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What affects the cost of fire rated sealant
We quote each job individually. This is what makes a difference:
- The type of sealant required
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
- How much there is to do
What it costs depends on the size of the job, 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.
What we need to know
Before you ask for a quote, have a think about:
- Photos by email, if that’s easy
- How we’d reach the joints
- If someone has resealed it before
- If it’s domestic, commercial or a hotel
It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you’re ready, ring 0345 464 0079 or send us an email.

Fire rated sealant around Merston
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.
For buildings such as Church of St Giles, gaps around pipes and cables are worth checking after any building work there. For site and facilities teams at buildings such as North Mundham Primary School, service openings in fire-resisting walls need checking after any refurbishment.
