Fire stopping in North Street, done properly
Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. Site teams most often ask us about unsealed openings around new pipes and cables and snag lists that include open service penetrations, on pipe penetrations, service gaps in risers and small duct penetrations where the tested detail allows. One point of contact handles commercial sealant work in North Street from the first photos to the final walk-round, for single jobs and planned programmes alike.
Barn and farm-building conversions near places like North 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.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

On site: what to expect
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. For work around North Street, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Have the specification and drawings to hand
- Tell us which areas need to stay in use
- Tell us your opening times and when work is allowed

Signs you need fire stopping in North Street
Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.
If one of these sounds familiar, it’s time for a closer look:
- Openings found when ceilings come down for a refit
- Fire-stopping items raised at inspection or handover
- Seals disturbed by maintenance and left open
- Unsealed joints where partitions meet the slab
In a school such as Ropley Church of England Primary School, fire-rated sealant goes in around service penetrations where it is specified.
Questions to ask before you book
- How they’ll work around occupants
- Who will actually carry out the work
- What the guarantee covers, and for how long
- Do they follow the manufacturer’s priming guidance?
Cost factors for service penetrations
The price varies from site to site. Expect it to depend on:
- Removal of failed or old sealant
- Working within restricted access windows
- The size and state of each joint
- Location, for remote and island sites
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
Details that help us quote
Whether it’s one area or a whole building, these details speed things up:
- How the joints are reached, and at what height
- Clear photos of the problem areas
- The site address and postcode
- Specification clauses that apply
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
Questions about North Street
Is North Street too far out for you?
Not at all. North Street is within our area. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can you work at a site such as Lower Soldridge Business Park, by North Street?
Yes. Our area takes in North Street and its surroundings, with estates and business parks such as Lower Soldridge Business Park included. To start, just speak to us on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
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.
What changes on 2 September 2029?
In England, references to the older BS 476 national classes are being removed from Approved Document B from 2 September 2029. The European route, BS EN 13501-2, then applies. Product selection stays with your designer.
Can you send site paperwork?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
Can you tell us what fire stopping our building needs?
No, that isn’t our role. With the designer’s details in hand, we can price the sealant elements, and tell you if a detail needs another product.
Where services cross fire walls in North Street
Central London is about 51 miles from North Street. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal. 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. What we install is set by the specification, and it goes in to the tested detail.
On a site such as Lower Soldridge Business Park (1.4 miles north-east of North Street), every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. Large healthcare estates like Alton Community Hospital, 5.1 miles to the north-east of North Street, change their services often, so penetration seals are worth checking after M&E work.
North Street is about 6 miles south-west of Alton, in Hampshire. Any commercial site in North Street is covered, for single jobs and planned programmes alike. North Street is one of 723 places we cover in Hampshire for service penetrations. Southampton is covered too, around 18 miles from North Street.

When to bring in a specialist
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.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in North Street can sit alongside others in a wider programme across Hampshire.
Surface by surface
Small ducts
Ducts are only sealed with sealant where the detail allows it. The ductwork, its supports and any dampers are for the ductwork contractor.
Risers and ceiling voids
Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically.
