Fire rated sealant in Selmeston
Fire stopping only performs as intended if it’s done to the detail: the right depth, the right backing and the right product for the substrate. That detail is what we take care over, gap by gap. Common call-outs are for ordinary sealant used where a fire-rated product was needed and joints picked up in a fire-stopping survey, across flats & HMOs, linear gaps and plasterboard & masonry.
For holiday lets, converted business premises or a community building near Selmeston, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
There’s a 12-month guarantee on every job, large or small.

Fire rated sealant around Selmeston
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 work to the specification you’re given, installing the product to its tested details.
If you let a flat or house near Berwick (Sussex) station, any gap left by new services in shared walls should be closed with a fire-rated product.
Selmeston is about 5 miles north of Seaford, in East Sussex.

Different surfaces, different methods
Service penetrations
New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in with backing where the detail needs it.
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail and we’ll flag it.
What affects the cost of fire rated sealant
We quote each job individually. This is what makes a difference:
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- How easy the joints are to reach
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
Asking for a quote
What to tell us when you ask for a quote:
- The type of property
- How we’d reach the joints
- What’s wrong with the joints now
- The address or postcode of the job
For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we’ll explain what’s involved.
The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It usually takes a few hours for a handful of gaps, and longer for a whole building. In a small place like Selmeston, access is normally 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.
- 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.
- We record the locations and products used for your records.
Getting ready for the visit
- Move anything stored near the joints
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children

When to call us in Selmeston
Buildings are refitted and reconfigured over the years. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
Common reasons people contact us are:
- Open holes round services passing through fire walls
- Standard silicone or caulk in a fire-stopping gap
- Joints picked up in a fire-stopping survey
- Gaps left after a refit or conversion
If you look after a church, hall or community building such as The Parish Church of St Mary, gaps around pipes and cables are worth checking after any building work there.
What to look for in a quote
- What the quote includes, VAT included or not
- How the joint is cleaned and prepared
- Whether you can choose the colour
- Who turns up on the day
What happens if it’s left?
A quick fill with any sealant to hand is not fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Around Selmeston, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
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 fails, we can still redo it.
FAQs for Selmeston
Can you help a landlord with a rental near Berwick (Sussex) station?
Yes. We work for letting agents and landlords as well as householders. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Is Selmeston in your area for fire rated sealant?

Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you’ll get one quote.
Is intumescent sealant the same as fire-rated sealant?
An intumescent sealant expands when it gets hot. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Can you tell me how many minutes the seal will last?
Ratings and certificates are not something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves.
What does fire rated sealant cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
Are you fully insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
When something else is needed
We won’t take on work that will not last, so these are the limits:
- Issuing a fire rating or certificate for a building
- Construction that does not provide fire resistance on its own
- Large holes that need a different fire-stopping system
If you are not sure, just phone 0345 464 0079 or email us and we will give you a straight answer.
