Fire rated sealant for homes and businesses in Green End
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, with a record of the products and locations if you need one. Common call-outs are for fire stopping disturbed by later work and gaps filled with a product that isn’t fire-rated, across flats & HMOs, service penetrations and linear gaps.
For holiday lets, converted business premises or a community building near Green End, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
All of our work is guaranteed for twelve months.

Signs you need fire rated sealant in Green End
Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.
Look out for these signs:
- New service routes left unsealed after building work
- Fire seals that have cracked with movement
- Gaps around pipes and cables through fire-resisting walls
- Open joints along the top of partitions
If you look after a building such as Sandon Junior Mixed and Infant School, fire-stopping around service openings should be restored whenever new services go in.
Questions to ask before booking
- Which colour the sealant will be
- Which sealant they’ll use, and why
- What preparation is included
- Are they insured?
How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It generally takes a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Green End, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Finally, we list where we worked and what we used, for your records.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises
- Try not to wet indoor joints just before the visit

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.
Advice
Fire rated sealant around Green End
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’re given, installing the product to its tested details.
For landlords with property near Ashwell & Morden station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For buildings such as Church of All Saints, service openings in its walls need the right fire-rated sealant, as in any building.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Questions from Green End
Is Green End within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Ashwell & Morden station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Can new sealant go over the old?
No, and we never do. 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 certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and list the locations and products for you.
Can you tell me which gaps need fire stopping?
No. We follow the requirements from your assessor, designer or building control, and apply each product to its tested details.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few photos.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Photograph sealed gaps before they’re covered up
- Allow for resealing whenever new services are run
- Tell trades working in the building that fire seals must be put back
- Store the list of sealed gaps with your building paperwork
Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint and we will tell you which one you have.
Open gaps don’t only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
For landlords and businesses
For anyone letting property in or around Green End, several properties can be quoted together. Send us the addresses and the work at each.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

What happens if it’s left?
Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. Where a wall is exposed, as many are in small places like Green End, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
