Fire Rated Sealant in Oaklands
Fire rated sealant across Oaklands and nearby, with old sealant always removed completely.
- Gaps where walls meet ceilings or slabs
- Damaged fire sealant left by other trades
- Fire seals that have cracked with movement
How it works
Before we leave, we go over the finished joints with you. The visit itself usually 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. For a job in Oaklands, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- Where the tested detail needs backing or fill, we fit it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- We record the locations and products used for your records.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can

Do you need fire rated sealant in Oaklands?
Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It may look fine, but it is not a fire-rated seal.
Signs it’s time to call us include:
- Fire stopping disturbed by later work
- Standard silicone or caulk in a fire-stopping gap
- Cracked or shrunken fire-rated sealant
- Open joints along the top of partitions
Rented homes near Welwyn North station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.
What your quote should include
- Whether all the old sealant comes out first
- The length of the guarantee
- When the joint can take water or movement
- What happens if they find a problem under the old sealant
Why act early in Oaklands
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. Around Oaklands, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

- Anti-fungal silicone where joints get wet

Fire rated sealant around Oaklands
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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 Church of St Michael and All Angels, service openings in its walls need the right fire-rated sealant, as in any building. For site and facilities teams at buildings such as Oaklands Primary School, service openings in fire-resisting walls need checking after any refurbishment.

How to look after the new joints
To keep the joints looking good and working properly:
- Include hidden areas like risers in routine checks
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Ask every contractor to reseal any fire stopping they disturb
- Take pictures of fire stopping before ceilings or boxing go back
Any fire seal that is cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Closing it is normally a straightforward job.

Questions from Oaklands
Is Oaklands in your area for fire rated sealant?
Yes, Oaklands is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing.
Will you come out to Oaklands?
Yes, Oaklands is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
How long does fire rated sealant take?
It depends on the size of the job, but most jobs take a few hours for a handful of gaps, and longer for a whole building. We will give you a better idea when we quote.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.

Your quote is based on your job. We take into account:
