Fire stopping in Martyr Worthy
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
How the job changes by surface
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter and we work within those limits.
Drylining partitions
Drylined fire walls are tested in a particular build-up. We check that the product’s detail covers that partition type and board thickness before sealing.
Fire stopping in Martyr Worthy, done properly
It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on sites in Martyr Worthy. We work on cable penetrations, linear gaps at wall heads and joints between fire-resisting walls and floors, and the failures we are asked to look at most are service penetrations left open after M&E works and seals that don’t match their tested detail. Whether you call it commercial sealant work, mastic application or joint sealing, in Martyr Worthy it comes down to the same thing: the right product in a properly prepared joint.
Smaller places such as Martyr Worthy still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Why deal with it now?
Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed, so earlier action pays back. Converted and older buildings near places like Martyr Worthy tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
A quote for service penetrations depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

What we can’t put right
Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:
- Construction that lacks the fire resistance the seal relies on
- Signing off or certifying a building’s fire stopping
- Large openings beyond what any sealant detail covers
If in doubt, phone 01277 525 020 or email a schedule or drawings and we’ll say what we think.

Questions we are asked in Martyr Worthy
Is a smaller place like Martyr Worthy outside your area?
Not at all. Martyr Worthy is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Martyr Worthy?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Do you offer coloured sealant?
It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.

Cost factors for service penetrations
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Distance, for remote addresses
- Induction, permit and paperwork requirements
- Whether old sealant has to be cut out first
- The total length or number of joints
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
Details that help us quote
To price the job accurately, we need a clear picture of the site. Send us:
- What the building is and how it’s used
- When you need the work done
- Where the site is, with the postcode
- Access details, including height
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Diagnose, treat, sign off
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Martyr Worthy may need directions, gate codes or a contact on site. 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.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
Preparing the site
