Fire rated sealant in Langley End, done properly
A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That detail is what we take care over. Common call-outs are for joints picked up in a fire-stopping survey and open joints along the top of partitions, on service penetrations, plasterboard & masonry and flats & HMOs.
If you have holiday lets, a converted barn used for business or a community building near Langley End, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
For anyone letting property in or around Langley End, jobs at different addresses can be quoted together. Send us the addresses and the work at each.
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Fire rated sealant around Langley End
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Letting a property close to Stevenage station? Then any gap left by new services in shared walls should be closed with a fire-rated product. Community buildings like All Saints Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Langley End: your questions answered
Do you cover smaller places like Langley End?
Yes. Langley End is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Stevenage station?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Do you take on fire stopping in schools and offices?
Yes. Occupied flats, HMOs, offices and schools are all fine, with access planned around residents or staff. Out-of-hours work can be arranged.
How long does the job take?
It depends on the size of the job, but most jobs take anything from a few hours to several days, depending on how many gaps there are. We’ll tell you when we quote.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Is standard sealant good enough for a fire gap?
No. Where a fire-rated seal is needed, it has to be a product tested for that use.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes from a few hours to a few days, depending on the number of gaps and the access and we leave things clean and tidy. In a small place like Langley End, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
How to prepare
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area

Signs you need fire rated sealant in Langley End
Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
Keep an eye out for any of the following:
- Door frames with gaps between frame and wall
- Gaps around pipes and cables through fire-resisting walls
- Fire seals that have cracked with movement
- Gaps filled with a product that is not fire-rated
Managing a site like The John Henry Newman School? Then fire-stopping around service openings should be restored whenever new services go in.
Before you book anyone
- What happens if the job turns out different
- Whether they seal over old material or remove it
- Who does the work, and how experienced they are
- How the surfaces are prepared before sealing
When something else is needed
New sealant cannot fix everything, and we will tell you before any work starts. It will not solve:
- A wall that is not a fire-resisting element to begin with
- Assessing a building’s fire safety
- Problems with the door itself rather than the gap around the frame
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.
Joints and surfaces we work on

What the job involves on each surface
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.
Door frames
We deal with the gap around the frame, not the door. Doors, seals and closers are for a door specialist.
