Fire stopping in Portmore
We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required. What we bring is careful installation of the specified sealant, to the maker’s guidance in Portmore and nearby. The enquiries we see most involve old intumescent sealant that has split away and openings found when ceilings come down for a refit, across cable penetrations, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows. One point of contact handles commercial sealant work in Portmore from the first photographs to the final walk-round, whether it’s one building or several.
Around smaller places like Portmore, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Work for main contractors and building owners
When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Penetration seals near Portmore
The area within 2 miles of Portmore holds a number of hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. For England, the fire stopping of penetrations is dealt with in Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
Schools such as Southlands School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. In a hotel such as Macdonald Elmers Court Hotel & Resort (1.2 miles south of Portmore), new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.
Portmore is about 2 miles north-east of Lymington, in Hampshire. Across the SO41 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 723 places in Hampshire, from busy centres to rural villages. Sites around Southampton have their own page, roughly 11 miles from Portmore.
Postcode districts covered here: SO41. If your site is on Warborne Lane, Jordans Lane and Main Road or close by, we can quote for service penetrations. Just outside Portmore, we also work in Warborne (1 mile west), Pilley (1 mile north-west), Bull Hill (1 mile north), Pilley Bailey (1 mile north) and Walhampton (1 mile south). Bigger towns within reach include Eastleigh (15 miles north-east), Fareham (15 miles east), Totton (10 miles north), Hedge End (14 miles north-east), Romsey (15 miles north) and Hythe (8 miles north-east).

Your questions answered
Would you work within a site like Lymington New Forest Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
How does the move away from BS 476 affect penetration seals in Portmore?
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.
How much does the work cost?
Each job is quoted on its own details. For yours, give us a call on 01277 525 020 or email us.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
What if there’s asbestos in the old mastic?
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.
Can staff carry on working while you’re here?
Normally, yes. Phased work can be planned so areas stay in use.
How long does a typical visit take?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
Do you need fire stopping in Portmore?
A common fault is a product that was never fire-rated in the first place: expanding foam or a general-purpose sealant pushed into a gap to tidy it. It may look closed, but it has no tested fire performance in that position, so it has to come out.
Clients typically get in touch after noticing something like this:
- Non-fire-rated filler around services
- Fire sealant pulled out of the opening
- Unsealed penetrations discovered above suspended ceilings
- Head-of-wall gaps with no fire seal
Halls and meeting rooms at places like Saint Nicholas Chapel sometimes gain new services, and any compartment wall crossed needs the specified seal.
What to look for in a quote
- Will RAMS and insurance details be available?
- Which product they’ll use, and why it suits the joint
- Their public liability cover
- Can the work be phased to keep areas open?
Why it’s worth doing now in Portmore
Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed. One visit to deal with every failing joint makes more sense than several trips to a place like Portmore. Photos of every joint help us quote for the whole job.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Why us?
- Public liability insurance in place
- Joints cleaned back to sound surfaces
- Clear, fixed quotes
- CHAS accredited contractor

Cost factors for service penetrations
We price every job individually. The things that drive the figure:
- Any access equipment needed
- Travel to remote or island sites
- Phasing around occupants
- Removal of failed or old sealant
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
What we need to price the job
A few photos plus some basic facts will normally do. It helps to include:
- Rough lengths or quantities, or drawings if you have them
- When you need the work done
- The type of building and who uses it
- A wide shot and a close-up of the area
Pricing a project or setting a maintenance budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, speak to us on 01277 525 020 or email a schedule or drawings.

Diagnose, treat, sign off
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking anything from one day to a planned run of visits, depending on the number of seals and the access. For work around Portmore, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- 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.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- 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.
Before we start on site
- Share the asbestos register for older buildings
- Arrange parking or a loading space
- Warn occupants and staff about the work
