Fire rated sealant for homes and businesses in Aldbury
Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it, so we follow the tested detail for each one. We are often asked to deal with gaps filled with a product that isn’t fire-rated and new service routes left unsealed after building work, on door frames, pipe & cable gaps and service penetrations.
In a village or hamlet like Aldbury, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Aldbury: your questions answered
Can you do fire rated sealant in Aldbury?
Yes. Our work covers London and the South East, and Aldbury is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Can you help a landlord with a rental near Tring station?
Yes. We work for landlords and letting agents as well as homeowners. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can I use normal mastic around a pipe through a fire wall?
No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. If it’s been used, we remove it and use the right product.
Is intumescent sealant the same as fire-rated sealant?
Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant and which one is used depends on the job.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
What do you need from me for a quote?
A short description and the location, plus pictures if you have them. We will ask anything else we need to know.
Common problems we fix in Aldbury
Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
The problems people usually mention when they call are:
- Damaged fire sealant left by other trades
- Joints picked up in a fire-stopping survey
- Fire seals that have cracked with movement
- Standard silicone or caulk in a fire-stopping gap
If you let a flat or house near Tring station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
Before booking anyone
- Whether they’re fully insured
- Whether VAT is included
- The length of the guarantee
- Whether they seal over old material or remove it
Honest limits
We’ll always be straight with you, so here’s what new sealant won’t do:
- Openings too large for sealant, which need batts, boards or another system
- Problems with the door itself rather than the gap around the frame
- Sign-off of the building, which sits with building control or your assessor
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.

Housing providers, facilities teams and property managers book us too in Aldbury and across Hertfordshire. We can quote a run of properties together.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out 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.
The process
You don’t 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. For a village or hamlet like Aldbury, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- We apply and tool the sealant to the product’s tested detail.
- We record what was done and flag anything that needs a different system.
How to prepare
- Let us know about earlier repairs to the joints
- On commercial sites, let us know about site rules
- Tell us if parking is tricky

Different surfaces, different methods
Masonry and concrete
Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it.
Service penetrations
New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in.
Fire rated sealant in Aldbury: 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, 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.
If you look after a church, hall or community building such as Church of St John the Baptist, gaps around pipes and cables are worth checking after any building work there. If you look after a building such as Aldbury Church of England Primary School, fire-stopping around service openings should be restored whenever new services go in.

Why act early in Aldbury
Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, and we work to the product details every time. Older cottages and farmhouses around Aldbury can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.
