How we handle fire rated sealant in Knotty Green
Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through. We are often asked to deal with gaps left after a refit or conversion and fire stopping disturbed by later work, across service penetrations, flats & HMOs and pipe & cable gaps.
Somewhere as small as Knotty Green, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
Whatever the size of the job, you get the same 12-month guarantee.

Common problems we fix in Knotty Green
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.
Common reasons people contact us include:
- Gaps around pipes and cables through fire-resisting walls
- Gaps where walls meet ceilings or slabs
- Unsealed gaps around fire door frames
- Joints picked up in a fire-stopping survey
For site and facilities teams at buildings such as St Mary and All Saints CofE Primary School, fire-stopping around service openings should be restored whenever new services go in.

Workplaces and buildings in Knotty Green
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
For buildings such as Church of St Michael and All Angels, older buildings that have had new heating or wiring often have service gaps worth checking. If you let a flat or house near Beaconsfield station, any gap left by new services in shared walls should be closed with a fire-rated product.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Make resealing part of every contractor’s brief
- Check whether a sealant can be painted before decorating over it
- Include hidden areas like risers in routine checks
- Keep the record of products and locations with your fire safety documents
Do not add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. Ask us if you are not sure which product was used.
Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
Questions from Knotty Green
Is Knotty Green within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Beaconsfield station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
What should I tell you?
Tell us what needs doing and where, with pictures by email if possible. If we need more, we’ll ask.
Can you do several jobs on one visit?
Yes. More than one area can be quoted together.
Can I use normal mastic around a pipe through a fire wall?
No. It looks sealed but won’t perform as fire stopping. Use a product tested for that gap and service and we can apply it for you.
Can new sealant go over the old?
No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
How much does fire rated sealant cost in Knotty Green?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or email us and tell us what needs doing and where.
Can you tell me which gaps need fire stopping?
No. That is for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.
Why act early in Knotty Green
Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own that doesn’t depend on other work. In a small place like Knotty Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
Why book with us
- Sanitary silicone with an anti-fungal additive in wet areas
- Neat joints and a tidy finish
- Domestic, commercial and hotel work
- Old sealant always removed completely
What the job involves on each surface
Plasterboard walls
We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.
Flats and HMOs
Working in occupied flats needs some planning. We agree access to each flat and the common parts before we start to keep disruption down.
The process
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Knotty Green, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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 and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your files.
Before we arrive
- Let us know about earlier repairs to the joints
- Mention any tricky access
- Tell us if parking is tricky
