Fire Rated Sealant in Stonymarsh
Our applicators work in Stonymarsh on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Gaps flagged on a fire risk assessment
- Holes left by a change of layout
- Cracked or shrunken fire-rated sealant
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
How we handle fire rated sealant in Stonymarsh
Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it. If you have gaps filled with a product that isn’t fire-rated and open holes round services passing through fire walls, we can help, on linear gaps, flats & HMOs and pipe & cable gaps alike.
Work in a small place like Stonymarsh is planned ahead, journey included, so it can be fitted around guests, clients or events where possible.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that 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. Somewhere as small as Stonymarsh, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Any non-fire-rated filler is removed.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts

Surface by surface
Masonry and concrete
Preparation counts on brick, block and concrete. We brush and vacuum the gap and use backing where the detail needs it before the sealant goes in.
Door frames
We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Report cracked or damaged seals as soon as you notice them
- Ask every contractor to reseal any fire stopping they disturb
- Take photos of fire stopping before ceilings or boxing go back
- Keep the record of products and locations with your fire safety documents
Any fire seal that’s cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.
Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.

Workplaces and buildings in Stonymarsh
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 are given, installing the product to its tested details.
If you look after a church, hall or community building such as Church of St Andrew, gaps around pipes and cables are worth checking after any building work there.

Stonymarsh questions
Can you do fire rated sealant in Stonymarsh?
Yes, Stonymarsh is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Do you work for landlords with property near Mottisfont & Dunbridge station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can ring 0345 464 0079 or email us with the details for a clear quote.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do you carry out fire risk assessments?
No. We work from the specification you give us, and apply each product to its tested details.
Do you certify the fire stopping?
We do not issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves.
How do I get a quote for fire rated sealant in Stonymarsh?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Can I use normal mastic around a pipe through a fire wall?
No. Standard sealants aren’t made or tested to stop fire. We cut it out and reseal with a fire-rated product.
Do you seal gaps around fire door frames?
Yes, where the gap suits a sealant detail. We seal the frame-to-wall gap, not the door itself.
Signs you need fire rated sealant in Stonymarsh
In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It may look fine, but it isn’t a fire-rated seal.
The most common problems we see are:
- Fire stopping disturbed by later work
- Gaps filled with a product that isn’t fire-rated
- Old fire sealant that has split or come away
- Gaps around pipes and cables through fire-resisting walls
If you let a flat or house near Mottisfont & Dunbridge station, any gap left by new services in shared walls should be closed with a fire-rated product.
