Fire rated sealant for homes and businesses in Botley
We don’t assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. Common call-outs are for cracked or shrunken fire-rated sealant and sealant items on a fire risk assessment action list, on door frames, flats & HMOs and linear gaps.
Commercial work around a smaller place like Botley normally means a pub, a shop, a school or small business units rather than office blocks. Each needs the same care with its sealant as any larger building.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or drop us an email.

Why it’s worth doing now in Botley
Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing when the building is next checked. In an older home around Botley, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email.

Signs you need fire rated sealant in Botley
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it is not installed as tested. Rushed fire stopping is common.
Any of these means the joints need attention:
- Damaged fire sealant left by other trades
- Gaps left after a refit or conversion
- Unsealed gaps around fire door frames
- Open holes round services passing through fire walls
If you let a flat or house near Botley station, any gap left by new services in shared walls should be closed with a fire-rated product.
What to look for in a quote
- What insurance they hold
- How long the guarantee is
- Whether they seal over old material or remove it
- Which sealant they’ll use, and why
When it isn’t the sealant
We will always be straight with you, so here’s what sealant can’t fix:
- Deciding what fire stopping a building needs
- A wall that is not a fire-resisting element to begin with
- Big openings where sealant alone is not the tested solution
If you are not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer before you book.

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Fire rated sealant around Botley
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.
Schools such as Botley Church of England Controlled Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. Community buildings like Church of All Saints are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

How it works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes a few hours for a handful of gaps, and longer for a whole building, depending on the size of the job. In a smaller place like Botley, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your records.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints
