Fire stopping for Broad Street sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
When something else is needed
Honesty saves time and money. New sealant won’t cure:
- Gaps in walls that were never built as compartment walls
- Plastic pipes whose detail calls for a collar or wrap
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If in doubt, phone 01277 525 020 or email a schedule or drawings and we will say what we think.
Joints and surfaces we work on
- Pipe penetrations
- Cable penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
About our fire stopping in Broad Street
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail, not a rule of thumb. The enquiries we see most involve old intumescent sealant that has split away and seals that don’t match their tested detail, across service gaps in risers, joints between fire-resisting walls and floors and cable penetrations. For commercial sealant work in Broad Street, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Barn and farm-building conversions near places like Broad Street 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.
Every job we finish is backed by a 12-month workmanship guarantee, in Broad Street as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Work for main contractors and building owners
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Broad Street can form part of a wider programme.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Why deal with it now?
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, so it makes sense to get it right first time. Older rural buildings around Broad Street move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Questions about Broad Street
Can you seal penetrations in a hotel in Broad Street after a refit?
Yes. We install fire-rated and intumescent sealant where it is specified. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
What does the BS 476 change mean for fire-rated sealant in Broad Street?
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.
Do you work in Broad Street?
Yes. Broad Street is in our area. To discuss a job, phone 01277 525 020 or email the details over.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited and a Constructionline member.
Will you come and look before quoting?
It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs normally get a visit.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
What affects the price in Broad Street
Quotes vary with the job. It mainly depends on:
- The size and state of each joint
- Quantities, in metres or numbers
- Removal of failed or old sealant
- How accessible the joints are
There’s no price list, because the scope varies so much from one building to the next. Call for a quote.
What we need to price the job
Diagnosis starts before we arrive. Tell us:
- Any dates the work must fit around
- Specification clauses that apply
- The type of building and who uses it
- The site address and postcode
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call 01277 525 020 or email the details over.
Compartment walls and floors in Broad Street
Fire stopping of openings and penetrations in England falls under Approved Document B.

Our part stays the same: the specified product, installed to its tested detail. Broad Street has several hotels close by, all within 2 miles. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.

- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.

Advice
What the job involves on each surface
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.
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.
