How we handle fire rated sealant in Alperton
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. Typical jobs include sealant items on a fire risk assessment action list and gaps around pipes and cables through fire-resisting walls, across door frames, plasterboard & masonry and flats & HMOs.
In London, a commercial job often starts with access: loading bays, building rules and lifts. For a building in Alperton, we agree timings and access before anything starts.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

How the job changes by surface
Flats and HMOs
Conversions usually leave a mix of old and new service holes. We seal the ones on your specification with a tested product and record where they are.
Door frames
Frame gaps are generally hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size.
How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on how many gaps there are. In Alperton, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products.
Preparing for the visit
- Mention any tricky access
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions

Alperton questions
I let a flat near Wembley Central station. Can you help?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Do you take on hotel work around Alperton?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Can ordinary silicone be used in a fire-stopping gap?
No. Where a fire-rated seal is needed, it has to be a product tested for that use.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can you fill the gap behind a fire door frame?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product following the tested details. The door, its seals and closer are for a door specialist.
Fire rated sealant in Alperton: local notes
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 are given, installing the product to its tested details. Alperton has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.
If you look after a church, hall or community building such as St James Church Alperton, service openings in its walls need the right fire-rated sealant, as in any building. Rented homes near Wembley Central station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

What to look for in a quote
- Who turns up on the day
- Which colour the sealant will be
- What product goes in the joint
- What the quote includes, VAT included or not
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Leave it or put it right?
Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, so we follow the maker’s details on every gap. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
