Fire rated sealant in Hartwell, done properly
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it. If you have sealant items on a fire risk assessment action list and cracked or shrunken fire-rated sealant, we can help, whatever the surface.
For a small place like Hartwell, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.
Whatever the size of the job, you get the same one-year guarantee in Hartwell and across Buckinghamshire.

Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Commercial buildings in Hartwell
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.
For landlords with property near Aylesbury station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Community buildings like St Mary's Church are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Hartwell questions
Is Hartwell in your area for fire rated sealant?
Yes. Our work covers London and the South East, and Hartwell is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
Do you work for landlords with property near Aylesbury station?
Yes. We work for landlords and agents as well as householders. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Can you work in occupied buildings?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we will plan the work to suit.
Is intumescent sealant the same as fire-rated sealant?
An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all and which one is used depends on the job.
Do you guarantee your work?
Yes, always. There’s a 12-month guarantee on every job, wherever you are.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
How the job changes by surface
Service penetrations
Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. The sealant is chosen for what passes through and how wide the gap is.
Door frames
Frame gaps are normally hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.
Signs you need fire rated sealant in Hartwell
A lot of fire stopping is out of sight: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.
Most people get in touch after spotting something like this:
- New service routes left unsealed after building work
- Standard silicone or caulk in a fire-stopping gap
- Open gaps behind door architraves
- Gaps where walls meet ceilings or slabs
Schools such as Stone Church of England Combined School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.
What your quote should include
- Whether all the old sealant comes out first
- What product goes in the joint
- How the joint is cleaned and prepared
- How long the guarantee is
What happens on the day
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as Hartwell, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We plan the order of work and access, floor by floor or flat by flat.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Clear items away from the joints we are working on
- For business premises, tell us about site rules or sign-in
