Mapesbury Fire Rated Sealant
Intumescent and fire-rated sealant around gaps, frames and service penetrations for householders, landlords and businesses in Mapesbury. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- New service routes left unsealed after building work
- Cracked or shrunken fire-rated sealant
- Open holes round services passing through fire walls
Looking after it afterwards
To keep the joints looking good and working properly:
- Ask every contractor to reseal any fire stopping they disturb
- Check risers, ceiling voids and cupboards during building checks
- Check whether a sealant can be painted before decorating over it
- Allow for resealing whenever new services are run
Keep the record we give you with the building’s fire safety documents. It saves time at the next inspection or assessment.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.
Fire rated sealant for homes and businesses in Mapesbury
Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then the sealant goes in to the depth the product’s details set. We work on linear gaps, pipe & cable gaps and flats & HMOs, and common reasons people get in touch are unsealed gaps around fire door frames and gaps around pipes and cables through fire-resisting walls.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. Timings and access are agreed with the building before work starts in Mapesbury.
A 12-month guarantee comes as standard.

What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Issuing a fire rating or certificate for a building
- Doors that are not fire doors in the first place
- Large holes that need a different fire-stopping system
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.

How the visit works
You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes a few hours for a handful of gaps, and longer for a whole building for a typical job. 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.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- We remove any old or unsuitable filler and clean the gap.
- Backing or fill is fitted where the product’s tested detail calls for it.
- 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.
Getting ready for the visit
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed

How we quote for fire rated sealant
Your quote is based on your job. We take into account:
- The number of rooms or windows
- Whether the work is at height
- Any working-time requirements on site
- The old material and how stubborn it is
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.
Helping us quote
To help us quote quickly, let us know:
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
- How we’d reach the joints
- Pictures of the joints, sent by email
Getting a quote is simple: let us know what needs doing and where. Photos by email help us understand the job, and we will take it from there.
Why deal with it now?
Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

FAQs for Mapesbury
Do you take on hotel work around Mapesbury?
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.
Is parking an issue for fire rated sealant in Mapesbury?
Parking in Mapesbury, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Do you cover Mapesbury?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
What fire rating will the seal have?
We don’t certify fire stopping or quote ratings. Our part is installing the specified product to its tested details and list the locations and products for you.
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.
Will you assess my building’s fire safety?
No. Your fire risk assessor, designer or building control decides that. Our job is applying the sealant to their specification.
What should I tell you?
Let us know what needs doing and where. If we need more, we’ll ask.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
What fire rated sealant looks like in Mapesbury
Commercial buildings in London often have strict access rules and limited loading, so out-of-hours working can be arranged where needed. Mapesbury has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.
Managing a site like St Joseph's RC Infant School? Then fire-stopping around service openings should be restored whenever new services go in. Rented homes near Wembley Stadium station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Flats and HMOs
In occupied buildings, we plan the order of work with you. We agree access to each flat and the common parts before work begins to keep disruption down.
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We fill it with a fire-rated product suited to the materials either side.
