Your questions about fire rated sealant in Adelphi
Is parking an issue for fire rated sealant in Adelphi?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Can you help a landlord with a rental near London Charing Cross station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
What fire rating will the seal have?
That is not something we state or certify. The requirement comes from your assessor, designer or building control, and we fit a product whose tested details meet it, recording the locations and products.
What does fire rated sealant cost?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or send us an email.
Do you take on fire stopping in schools and offices?
Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. We agree access and the order of work with you first.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Fire rated sealant in Adelphi
Fire stopping only performs as intended if it’s done to the detail: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over, one gap at a time. If you are dealing with unsealed gaps where pipes and cables go through a wall and holes left by a change of layout, we can help, whatever the surface.
In London, a commercial job often starts with access: loading bays, building rules and lifts. Timings and access are agreed with the building before work starts in Adelphi, and room-by-room programmes can be planned where needed.
Our work is backed for twelve months, in Adelphi and everywhere else we cover.

Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself normally takes a few hours for a handful of gaps, and longer for a whole building, depending on the amount of work. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Finally, we list where we worked and what we used, for your records.
Before we arrive
- Tell us about any water getting in
- Tell us if parking is tricky
- Keep children and pets away from the work area
How to get a quote
We do not publish a price list, because every job is different. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or drop us an email.
Advice
Commercial buildings in Adelphi
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. Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange.
For buildings such as Savoy Chapel, older buildings that have had new heating or wiring often have service gaps worth checking. If you look after a building such as St Clement Danes CofE Primary School, service openings in fire-resisting walls need checking after any refurbishment.

What sealant work can’t fix
We will not take on work that will not last, so here’s what sealant cannot put right:
- Deciding what fire stopping a building needs
- Big openings where sealant alone is not the tested solution
- Doors that aren’t fire doors in the first place
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.
Surfaces we seal
- Service penetrations
- Door frames
- Flats & HMOs
- Linear gaps
- Plasterboard & masonry
- Pipe & cable gaps
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Check risers, ceiling voids and cupboards during building checks
- Never patch a fire seal with standard sealant
- Make resealing part of every contractor’s brief
- Store the list of sealed gaps with your building paperwork
File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.
A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record.

What the job involves on each surface
Flats and HMOs
Working in occupied flats needs some planning. Access to flats and common areas is agreed in advance so residents know what to expect.
Linear gaps
Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement, following the tested detail.
What we are called out for in Adelphi
Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Knocks, maintenance and building work damage it further.
The most common problems we see are:
- Open joints along the top of partitions
- Door frames with gaps between frame and wall
- Gaps flagged on a fire risk assessment
- New service routes left unsealed after building work
If you let a flat or house near London Charing Cross station, any gap left by new services in shared walls should be closed with a fire-rated product.
