Fire-rated sealant in Ashurst, West Sussex
Fire rated sealant across Ashurst and nearby, with every bit of old sealant taken out first.
- Cracked or shrunken fire-rated sealant
- Joints picked up in a fire-stopping survey
- Gaps left after a refit or conversion
The process
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for a handful of gaps, and longer for a whole building. In a small place like Ashurst, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start with the survey or action list, checking the size and surfaces of every gap.
- We remove any old or unsuitable filler and clean the gap.
- Backing or fill is fitted where the product’s tested detail calls for it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- Finally, we list where we worked and what we used, for your records.
Before we arrive
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules
- Tell us if parking is tricky

Advice
About our fire rated sealant in Ashurst
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. We work on plasterboard & masonry, door frames and service penetrations, and common reasons people get in touch are seals cut through by electricians, plumbers or data installers and fire seals that have cracked with movement.
If you have holiday lets, a converted barn used for business or a community building near Ashurst, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
All of our work is guaranteed for twelve months.

When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Big openings where sealant alone is not the tested solution
- Assessing a building’s fire safety
- Doors that aren’t fire doors in the first place

FAQs for Ashurst
Do you cover Ashurst for fire rated sealant?
Yes. We work across London and the South East, and Ashurst is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing.
Is there a guarantee on fire rated sealant in Ashurst?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Can new sealant go over the old?
No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Do you work in flats, HMOs and commercial buildings?

Can you do several jobs on one visit?
Yes. Just list everything you need and you will get one quote.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Is intumescent sealant the same as fire-rated sealant?
Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we’re using.
Different surfaces, different methods
Door frames
A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.
Masonry and concrete
Core-drilled and broken-out holes in concrete are often irregular. We check the gap size around the service to make sure it suits the product.
Workplaces and buildings in Ashurst
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.
For site and facilities teams at buildings such as Ashurst CofE Primary School, fire-stopping around service openings should be restored whenever new services go in.

Leave it or put it right?
An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the work involved is often modest. In a small place like Ashurst, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email and we will talk you through it.

When to call us in Ashurst
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.
Signs it’s time to call us include:
- Door frames with gaps between frame and wall
- Cracked or shrunken fire-rated sealant
- Damaged fire sealant left by other trades
- Gaps filled with a product that isn’t fire-rated
For buildings such as The Parish Church of St James, service openings in its walls need the right fire-rated sealant, as in any building.
