Fire Rated Sealant in East Marden
Intumescent and fire-rated sealant around gaps, frames and service penetrations for homes and businesses in East Marden and across West Sussex. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Joints picked up in a fire-stopping survey
- Open gaps behind door architraves
- Open joints along the top of partitions
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Never patch a fire seal with standard sealant
- Don’t paint over fire sealant until it has cured
- Keep photos of seals that will be hidden
- Ask every contractor to reseal any fire stopping they disturb
Include fire stopping in your regular building checks. Watch for cracking, gaps or seals that have been disturbed and get them seen to.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
Fire rated sealant for homes and businesses in East Marden
We can work through a building room by room or floor by floor, noting the locations and products as we go. That record is useful for your files and for whoever looks at the building next. We work on door frames, pipe & cable gaps and linear gaps, and people most often call us about gaps where walls meet ceilings or slabs and holes left by a change of layout.
For holiday lets, converted business premises or a community building near East Marden, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
Big or small, it’s backed by our 12-month guarantee.

FAQs for East Marden
Do you cover smaller places like East Marden?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What guarantee comes with fire rated sealant in East Marden?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
What fire rating will the seal have?
We don’t issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer; we install to those details and record what we did.
Can I choose the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
Is standard sealant good enough for a fire gap?
No. It looks sealed but won’t perform as fire stopping. Use a product tested for that gap and service and we can apply it for you.
Fire rated sealant around East Marden
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
In and around East Marden, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint. If you look after a church, hall or community building such as Church of St Peter, gaps around pipes and cables are worth checking after any building work there.

When it isn’t the sealant
We’ll always be straight with you, so here’s what new sealant won’t do:
- Big openings where sealant alone is not the tested solution
- Deciding what fire stopping a building needs
- A wall that is not a fire-resisting element to begin with

What happens on the day
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes from a few hours to a few days, depending on the number of gaps and the access from start to finish. Somewhere like East Marden 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.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Finally, we list where we worked and what we used, for your records.

What the job involves on each surface
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Gaps that are too big for sealant alone need a different detail.
Masonry and concrete
For masonry and concrete, we use a product tested in that substrate. The gap is cleaned of dust first so the seal has something sound to bond to.
How we quote for fire rated sealant
Every job gets its own quote. This is what makes a difference:
- Whether old sealant or filler has to be cut out
- How many areas need sealing
- The product the joint needs
- Working hours on commercial sites
Doing several joints on one visit usually makes better use of the time than several visits. You will get one clear quote for the whole job.
What to tell us for a quote
To help us quote quickly, let us know:
- Any previous sealing or DIY work
- What’s wrong with the joints now
- A few photos by email, if you can
- Where the property is
Need a quote? Please call 0345 464 0079 or email us with a few details. You’ll know what we plan to do, and what it will cost, before any work begins.
Why act early in East Marden
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the work involved is often modest. Older cottages and farmhouses around East Marden can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you do try it yourself, take your time over the 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.
