Fire rated sealant for homes and businesses in Wembley Park
A fire seal relies on being installed the way it was tested: the right depth, the right backing and the right product for the substrate. That is the part we focus on. If you have gaps left after a refit or conversion and unsealed gaps around fire door frames, we can put it right, whatever the surface.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. In Wembley Park, building managers may need both fire-rated sealant around those openings and new sealant in shared washrooms.
Big or small, it’s backed by our 12-month guarantee.

Common problems we fix in Wembley Park
Many open fire-stopping gaps are made after the building is finished. Electricians, plumbers and data installers drill through walls and ceilings and the hole they leave does not always get resealed.
The most common problems we see are:
- Unsealed gaps around fire door frames
- Gaps where walls meet ceilings or slabs
- Holes left by a change of layout
- Gaps flagged on a fire risk assessment
As a London address, Wembley Park can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
Before you book anyone
- Is the old sealant removed completely?
- How much experience the applicator has
- Whether VAT is included
- What insurance they hold
Commercial buildings in Wembley Park
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, 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. Wembley Park 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 building such as Michaela Community School, service openings in fire-resisting walls need checking after any refurbishment. Community buildings like St Augustine are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

When something else is needed
We will not take on work that will not last, so here’s what sealant cannot put right:
- Walls or floors that weren’t built to resist fire
- Problems with the door itself rather than the gap around the frame
- Assessing a building’s fire safety
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.

- Flats & HMOs

What happens if it’s left?
Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it 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, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes anything from a few hours to several days, depending on how many gaps there are, depending on the amount of work. In Wembley Park, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products.
How to prepare
- Clear items away from the joints we’re working on
- Tell us about any previous sealing or DIY attempts
- Keep children and pets away from the work area

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Get damaged fire seals looked at promptly
- Keep photos of seals that will be hidden
- Check risers, ceiling voids and cupboards during building checks
- Do not paint over fire sealant until it has cured
Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. We can tell you which product we used.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole.
Wembley Park: your questions answered
Do you work for hotels and guest houses in Wembley Park?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Can parking be tricky for a visit in Wembley Park?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do you provide details of the products used?
Yes. Every gap we seal is listed with the product used so it’s there for the next inspection.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
What does intumescent mean?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant, and the choice depends on the gap.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Where do you work from?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.

Other services in Wembley Park
Different surfaces, different methods
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.
Door frames
Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.
