Fire Rated Sealant in Plumstead
Fire-stopping gaps in Plumstead need attention? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.
- Fire stopping disturbed by later work
- Joints picked up in a fire-stopping survey
- Gaps left after a refit or conversion
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Make resealing part of every contractor’s brief
- Do not paint over fire sealant until it has cured
- Include fire stopping when you schedule refits
Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.
If a fire risk assessment has flagged a gap, do not leave it for the next one. Have it sealed, then keep the record so the item can be closed.

Fire rated sealant in Plumstead: local notes
Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed. 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 work to the specification you’re given, installing the product to its tested details.
Plumstead is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For buildings such as St John's Church, older buildings that have had new heating or wiring often have service gaps worth checking.
Plumstead is about 8 miles east of London, in Greater London. From the centre of Plumstead to the outskirts, we cover fire rated sealant for every kind of property. Plumstead is one of 764 places in Greater London we cover. Our London page covers work nearby (8 miles or so).
All of SE18, SE28 and E16 is covered for fire rated sealant. If you need fire rated sealant at a property on Moy Lane, Love Lane and Tuam Road or anywhere close by, our applicators can take on the job. Plumstead is on the A206, which makes it straightforward to reach. We also cover the places around Plumstead: Woolwich (1 mile west), Shooter's Hill (1 mile south-west), East Wickham (1 mile south-east), Charlton (2 miles west) and New Charlton (2 miles west).

Different surfaces, different methods
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. They’re sealed with a fire-rated sealant over backing where the detail calls for it.
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.
Why it’s worth doing now in Plumstead
Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own that doesn’t depend on other work. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.
Why book with us
- Any old sealant cut out fully, not covered over
- An ARBOMaster approved applicator
- Anti-fungal silicone where joints get wet
- Fully insured

How it works
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. The work generally takes anything from a few hours to several days, depending on how many gaps there are. In Plumstead, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- Access to each area is agreed so the work can run in order.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
How to prepare
- Keep pets and children clear of the area while we work
- Clear the area around the work
- Tell us about any water getting in

Advice
Towns and villages near Plumstead
What else we do in Plumstead
Do you need fire rated sealant in Plumstead?
Door frames are a common weak spot. The gap between the frame and the wall is hidden behind the architrave, so it can be left open when a door is replaced.
Signs it’s time to call us include:
- Standard silicone or caulk in a fire-stopping gap
- Gaps flagged on a fire risk assessment
- Door frames with gaps between frame and wall
- Cracked or shrunken fire-rated sealant
If you look after a building such as South Rise Primary School, service openings in fire-resisting walls need checking after any refurbishment.
What to look for in a quote

Plumstead: your questions answered
Can you do fire rated sealant in Plumstead?
Yes, Plumstead is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear price.
Can parking be tricky for a visit in Plumstead?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you tell me how many minutes the seal will last?
We don’t 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; we install to those details and record what we did.
What do you need from me for a quote?
Tell us what needs doing and where, with pictures by email if possible. If we need more, we’ll ask.
Can you give us a record of the work?
Yes. Every gap we seal is listed with the product used so it’s there for the next inspection.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
