Fire stopping across Holyport
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
General trades versus a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
About our fire stopping in Holyport
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal. The enquiries we see most involve hidden openings found during inspections and head-of-wall gaps with no fire seal, across pipe penetrations, service gaps in risers and joints between fire-resisting walls and floors. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Holyport it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Rural conversions around Holyport 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.

FAQs: Holyport
How does the move away from BS 476 affect penetration seals in Holyport?
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.
Do you seal service penetrations in hotels around Holyport?
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.
Can the building stay open while you work?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Do you cover Holyport?
Yes. Sites across Holyport are covered.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.
Are you CHAS accredited?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Aftercare for building managers
A few simple habits keep the new joints working:
- Ask which product is in place before decorating
- Flag new cables with no seal around them
- Ask the designer to confirm details early on refits
- Include service cupboards in routine inspections
During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.
Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.
Commercial clients in Holyport
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Why deal with it now?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down and each detail can be checked as we go. Converted and older buildings near places like Holyport tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Compartments and services around Holyport
Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. Holyport has several hotels close by, all within 2 miles. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
Industrial units on estates such as Trade Park, 0.6 miles to the north-east of Holyport, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal. For a hospital such as St Mark's Hospital, 2.5 miles to the north-west of Holyport, penetration sealing is usually phased ward by ward, with infection-control rules agreed first. In a hotel such as Chauntry House Hotel (1.3 miles north-east of Holyport), new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. If others near Holyport need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- 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.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
What we need from you
- Make sure the joints can be reached
- Send your site hours and access windows
- Point out parking and an unloading spot

How the job changes by surface
Plastic pipes
Plastic pipes soften and collapse in a fire. Some intumescent sealants are tested on smaller plastic pipes, though larger ones typically call for a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
Drylining partitions
Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers first.
