Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules.
Fire stopping in Havenstreet
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 job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. Each seal follows the manufacturer’s tested detail rather than guesswork. We work on small duct penetrations where the tested detail allows, linear gaps at wall heads and cable penetrations, and what we’re called in for most is fire seals cut back for extra cables and never reinstated and non-fire-rated filler around services. A single leaking joint is often how a building in Havenstreet first comes to us: we look at the rest while we are there and tell you what we find.
A job near Havenstreet is usually planned around one visit, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

How the job changes by surface
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 we work within it.
Masonry and concrete
Block walls and concrete floors are common substrates for penetration seals. Dust and loose debris are cleared out of the opening, with backing added if the detail requires it.
Maintenance after handover
Problems stay small when the joints are checked regularly. Specifically:
- Flag new cables with no seal around them
- Look above ceilings when tiles are lifted for other jobs
- Ask which product is in place before decorating
- Foam or ordinary sealant is never a fire-seal repair
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. 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. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.
Site staff or a sealant specialist?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Signs you need fire stopping in Havenstreet
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 what we find most often.
Things that normally lead to an enquiry:
- Service penetrations left open after M&E works
- Penetration schedules that need working through
- Open linear gaps along the top of fire-resisting walls
- Unsealed penetrations discovered above suspended ceilings
Schools such as Ryde Academy often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

- Their approach to joint depth and backing
- How the existing material will be dealt with
- Their plan for phasing and protecting the area
From enquiry to sign-off
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Jobs in and around smaller places like Havenstreet are usually planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- 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.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Let us know about inductions and permits
- Move anything stored against the joints
- Let building users know which areas are affected

Fire-rated sealing for Havenstreet buildings
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. There are two care or nursing homes within about 2 miles of Havenstreet. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. We install fire-rated sealant to the tested detail where it is specified.
Tenant changes at parks like Wootton Business Park (2 miles west of Havenstreet) bring new data and services, and openings through fire-resisting walls need the specified seal. On a hospital site such as St Mary's Hospital, which lies west of Havenstreet, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
Havenstreet is about 2 miles south-west of Ryde, in the Isle of Wight. Havenstreet sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Havenstreet is one of 125 places in the Isle of Wight on our list. Portsmouth is covered too, some 9 miles away.

Questions we are asked in Havenstreet
How does the move away from BS 476 affect penetration seals in Havenstreet?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Will you work in a care home in Havenstreet without moving residents out?
Yes. We work around residents’ routines, a room or two at a time. Tell us about any infection-control or safeguarding requirements and we will work to them.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
Is colour matching possible?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Do you seal on top of existing 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.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
