Fire rated sealant in Crabtree
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That is the part we focus on. We are often asked to deal with unsealed gaps around fire door frames and fire seals that have cracked with movement, across service penetrations, plasterboard & masonry and pipe & cable gaps.
For holiday lets, converted business premises or a community building near Crabtree, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
You get a one-year guarantee, the same in Crabtree as everywhere else we work.

How it works
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as Crabtree, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your records.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- On commercial sites, let us know about site rules
- Let us know about stairs, lifts or work at height

Advice
Crabtree questions
Do you work for landlords with property near Horsham station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Is Crabtree within the area you cover?
Yes, Crabtree is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you do fire sealant around door frames?
Yes. We seal the gap between the frame and the wall with a suitable fire-rated product. The door leaf and its hardware need a door specialist.
What’s the difference between intumescent and fire-rated sealant?
Intumescent means it swells when heated to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.
How do I get a quote for fire rated sealant in Crabtree?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Do you provide details of the products used?
Yes. We record the locations we have sealed and the products used for your files.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can you work in occupied buildings?
Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. We agree access and the order of work with you first.
What sealant work can’t fix
Before you book, it’s worth knowing the limits:
- Deciding what fire stopping a building needs
- Problems with the door itself rather than the gap around the frame
- Large holes that need a different fire-stopping system
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before booking.

For fire rated sealant in Crabtree, phone 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
How the job changes by surface
Door frames
Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details.
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes are not treated the same. We follow the manufacturer’s tested detail for each.
Leave it or put it right?
For some gaps, sealant isn’t the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. We’ll say so if a gap needs something other than sealant. Older cottages and farmhouses around Crabtree can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and give you a clear price before we start.

Letting a property close to Horsham station? Then new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For site and facilities teams at buildings such as Newells Preparatory School, service openings in fire-resisting walls need checking after any refurbishment.
