Fire rated sealant in Abbey Wood
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. Each gap is sealed to the product maker’s tested detail for its size and substrate, with a record of the products and locations if you need one. If you are dealing with seals cut through by electricians, plumbers or data installers and door frames with gaps between frame and wall, we can help, on linear gaps, door frames and service penetrations alike.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Abbey Wood, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

What happens if it’s left?
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

Landlord and commercial work in Abbey Wood
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
We work for landlords and letting agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
The process
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes anything from a few hours to several days, depending on how many gaps there are. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products.
Getting ready for the visit
- Clear the area around the work
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks

Related advice
How we quote for fire rated sealant
For a quick quote, just ask. The main things that affect it are:
- How many areas need sealing
- Which sealant suits the joint
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.
What we need to know
Photos help, but a description is a good start. Please mention:
- Pictures of the joints, sent by email
- What’s wrong with the joints now
- The address or postcode of the job
- Roughly how big the job is
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or email us.

Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Different surfaces, different methods
Linear gaps
Long, narrow gaps appear where walls meet slabs and ceilings. We seal them to the tested detail, with backing where it’s needed.
Plasterboard walls
In plasterboard walls, the condition of the board edge matters. Loose material is removed so the sealant has a firm edge.
Fire rated sealant around Abbey Wood
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, 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.
As a London address, Abbey Wood can be tricky for parking: let us know about parking bays, permits or a driveway. Schools such as Alexander McLeod Primary School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. If you let a flat or house near Abbey Wood station, any gap left by new services in shared walls should be closed with a fire-rated product.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
