Signs you need fire stopping in Linwood
When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.
Site and facilities staff are often the first to spot these:
- Openings left by services added after handover
- Fire-stopping items raised at inspection or handover
- Old intumescent sealant that has split away
- Fire stopping installed outside its tested range
Around Linwood, fire-stopping design belongs to the designer and building control; installation to the specification is our part.

About our fire stopping in Linwood
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. We work on linear gaps at wall heads, small duct penetrations where the tested detail allows and joints between fire-resisting walls and floors, and what we are called in for most is head-of-wall gaps with no fire seal and service penetrations left open after M&E works. Looking for mastic applicators who cover Linwood? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Rural conversions around Linwood can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Linwood: questions and answers
How does the move away from BS 476 affect penetration seals in Linwood?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Can you produce the fire-stopping design for a job in Linwood?
No. The designer or fire engineer sets the detail and building control accepts it. Our part is installing the specified product to its tested detail, and telling you if the detail calls for something other than sealant.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
What do you charge?
Every job gets its own fixed quote. For yours, speak to us on 01277 525 020 or use the quote form with a description of the work.
Do you offer coloured sealant?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Why deal with it now?
Open penetrations multiply: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable, rather than turning into a full building survey and reseal. Halls, stores and units around places like Linwood may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

What the job involves on each surface
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest against the detail’s limits, and any that don’t are flagged.
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers and the installation has to fit inside those limits.

Diagnose, treat, sign off
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a building around Linwood, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Getting the site ready
- Confirm the product named in the specification
- Let us know about inductions and permits
- Share your working hours and any access restrictions
