Fire rated sealant for homes and businesses in Chelwood Common
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 is the part we focus on. Common call-outs are for standard silicone or caulk in a fire-stopping gap and gaps where walls meet ceilings or slabs, on linear gaps, plasterboard & masonry and door frames.
In a village or hamlet like Chelwood Common, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
Whatever the size of the job, you get the same 12-month guarantee.

Different surfaces, different methods
Flats and HMOs
Conversions usually leave a mix of old and new service holes. The gaps on your list are sealed with a fire-rated product and the locations noted.
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. The sealant is chosen for what passes through and how wide the gap is.

Workplaces and buildings in Chelwood Common
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.
For site and facilities teams at buildings such as Danehill Church of England Primary School, service openings in fire-resisting walls need checking after any refurbishment.

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What sealant work cannot fix
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Walls or floors that weren’t built to resist fire
- Deciding what fire stopping a building needs
- Large holes that need a different fire-stopping system
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before booking.
Surfaces we seal
- Linear gaps
- Flats & HMOs
- Pipe & cable gaps
- Door frames
- Plasterboard & masonry
- Service penetrations
Aftercare tips
After the cure time, these simple habits help:
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Get damaged fire seals looked at promptly
- Ask which product was used before you paint
- Ask every contractor to reseal any fire stopping they disturb
Don’t drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Sealing them early helps on every front.

Do the sealants smell?
Some sealants have a smell while they cure. Opening a window helps.

Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant.

Do you need fire rated sealant in Chelwood Common?
Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.
These are the problems we are asked about most:
- Damaged fire sealant left by other trades
- Linear gaps at the head of walls
- Standard silicone or caulk in a fire-stopping gap
- Joints picked up in a fire-stopping survey
For buildings such as Chelwood Gate Church, service openings in its walls need the right fire-rated sealant, as in any building.
