Fire Rated Sealant in Slindon
Fire-stopping gaps in Slindon need attention? We cut out the old, prepare the joints and apply the right sealant.
- Fire seals that have cracked with movement
- Gaps where walls meet ceilings or slabs
- Sealant items on a fire risk assessment action list
Fire rated sealant in Slindon, done properly
We don’t assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. If you have standard silicone or caulk in a fire-stopping gap and open holes round services passing through fire walls, we can help.
Somewhere as small as Slindon, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

How the job changes by surface
Door frames
Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details so the architrave can be refitted.
Linear gaps
Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Keep photos of seals that will be hidden
- Include hidden areas like risers in routine checks
- Store the list of sealed gaps with your building paperwork
- Include fire stopping when you schedule refits
File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.
If a fire risk assessment has flagged a gap, don’t leave it for the next one. Get it sealed and recorded so the item can be closed.
How it works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes from a few hours to a few days, depending on the number of gaps and the access, depending on the size of the job. Somewhere like Slindon needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out and the faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products.
Getting ready for the visit
- Clear items away from the joints we’re working on
- Let us know about parking restrictions
- Keep children and pets away from the work area

Commercial buildings in Slindon
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For buildings such as The Parish Church of St Mary, service openings in its walls need the right fire-rated sealant, as in any building. For site and facilities teams at buildings such as Slindon CofE Primary School, fire-stopping around service openings should be restored whenever new services go in.

Should I try it myself first?
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.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Slindon: your questions answered
Is Slindon in your area for fire rated sealant?
Yes, Slindon is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.
Is Slindon within the area you cover?
Yes, Slindon is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
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.
Can new sealant go over the old?
No. We remove every bit of old sealant first.
Do you carry out fire risk assessments?
No. We follow the requirements from your assessor, designer or building control and install to the manufacturer’s details.
Can you fill the gap behind a fire door frame?
Yes, where the gap suits a sealant detail. We seal the frame-to-wall gap, not the door itself and we’ll tell you if we spot problems with the door.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Why act early in Slindon
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. Where a wall is exposed, as many are in small places like Slindon, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

- Walls or floors that weren’t built to resist fire
- Assessing a building’s fire safety
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

What we are called out for in Slindon
A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.
Any of these means the joints need attention:
- Holes left by a change of layout
- Sealant items on a fire risk assessment action list
- Gaps filled with a product that isn’t fire-rated
- Open joints along the top of partitions
Rented homes near Barnham station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
