About our fire rated sealant in Westminster
Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. 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 open gaps behind door architraves and gaps filled with a product that isn’t fire-rated, we can put it right, whatever the surface.
In London’s blocks of flats, service risers and common parts have pipes and cables passing through walls and floors. For managing agents and building owners in Westminster, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
Every job comes with a one-year guarantee, wherever you are in Greater London.

Different surfaces, different methods
Service penetrations
A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. Each one is sealed to the product’s tested detail, and tell you if sealant alone isn’t the right fix.
Masonry and concrete
Holes through concrete and block are rarely neat. We measure the gap at its widest point against the product’s tested range.
Landlords, agents and businesses in Westminster
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What else we do in Westminster
Fire rated sealant in Westminster: local notes
Many London buildings have tight access and loading restrictions, so out-of-hours working can be arranged where needed. In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, 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, Westminster can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Community buildings like Christ Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there. For site and facilities teams at buildings such as Harris Westminster Sixth Form, fire-stopping around service openings should be restored whenever new services go in.

When it is not the sealant
To be straight with you, there are a few things sealant will not fix:
- Fire risk assessments, which need a qualified assessor
- Openings too large for sealant, which need batts, boards or another system
- Construction that doesn’t provide fire resistance on its own
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before you book.

How it works
There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes from a few hours to a few days, depending on the number of gaps and the access. In Westminster, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- We put in whatever backing or fill the product detail specifies.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- We record the locations and products used for your records.
Preparing for the visit
- Mention any leaks or damp you’ve noticed

Advice
What happens if it’s left?
Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing when the building is next checked. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Westminster, the repair is bigger than the sealant job would have been.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

Take a look at what affects the cost and what customers say.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Westminster questions
Do you work for landlords with property near London Victoria station?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Do you work for hotels and guest houses in Westminster?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Do you cover Westminster?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
Is the work guaranteed?
Yes. Every job comes with a 12-month guarantee.
Can you fill the gap behind a fire door frame?
Yes. We often seal open gaps hidden behind the architrave. The door and its fittings are a separate job for a door specialist.
