When it isn’t the sealant
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Large openings beyond what any sealant detail covers
- Deciding what a wall or floor needs, which belongs to the designer
- Reviewing a building’s overall fire safety
If in doubt, call the office on 01277 525 020 or email the details over and we will say what we think.
Joints and surfaces we work on
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Service gaps in risers
- Cable penetrations
- Small duct penetrations where the tested detail allows
Fire stopping in Thorpe Green, done properly
A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in, and we say so if it doesn’t fit. If you are dealing with non-fire-rated filler around services and unsealed penetrations discovered above suspended ceilings, we can help, on service gaps in risers, pipe penetrations and cable penetrations alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Thorpe Green it comes down to the same thing: the right product in a properly prepared joint.
Barn and farm-building conversions near places like Thorpe Green often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

How the job changes by surface
Drylining partitions
Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness before sealing.
Metal pipes
Heat travels along metal pipework, and the tested detail may ask for insulation beyond the wall. We follow whatever the detail requires and flag anything we can’t match.
Site staff or a sealant specialist?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Thorpe Green: questions and answers
What happens to BS 476 references for fire stopping in Thorpe Green?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Is Thorpe Green too far out for you?
Not at all. Thorpe Green is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also call the office on 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
How the quote is worked out
We price every job individually. The things that drive the figure:
- Removal of failed or old sealant
- The site’s rules and procedures
- Which sealant the job calls for
- How accessible the joints are
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Before you send an enquiry
However big the job, the same details help:
- Your programme or deadline
- Rough lengths or quantities, or drawings if you have them
- The asbestos register, for older buildings
- How the joints are reached, and at what height
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call the office on 01277 525 020 or send details through our quote form.

How a job runs
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open.

Send that with the details and we’ll confirm the plan with the quote.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
What we need from you
- Share your working hours and any access restrictions
- For older buildings, check the asbestos register before work
- Confirm the product named in the specification
Ask for a quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Signs you need fire stopping in Thorpe Green
When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.
Typical triggers for a call:
- Fire stopping installed outside its tested range
- Expanding foam used as fire stopping
- Unsealed joints where partitions meet the slab
- Fire sealant pulled out of the opening
For a hospital such as St Peter's Hospital, 2 miles to the south of Thorpe Green, penetration sealing is typically phased ward by ward, with infection-control rules agreed first.
