Fire stopping in Lower Swanwick
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. Most enquiries involve service penetrations left open after M&E works and seals that don’t match their tested detail, across small duct penetrations where the tested detail allows, linear gaps at wall heads and joints between fire-resisting walls and floors. Facilities teams, main contractors and managing agents in Lower Swanwick tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
A job near Lower Swanwick is typically planned around one visit, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What happens if it’s left?
Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these, and the other benefits follow. Converted and older buildings near places like Lower Swanwick tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Surface by surface
Risers and ceiling voids
Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically and tell you about openings outside the list.
Cables and cable bundles
New data and power cables are the most common breach we see. Openings around new cables are resealed to the detail, and we tell you if the bundle exceeds what sealant covers.
Maintenance after handover
Problems stay small when the joints are checked regularly. Specifically:
- Keep general-purpose fillers away from compartment walls
- Report damaged or disturbed seals as soon as they’re spotted
- Put resealing into every M&E and fit-out package
- Ask which product is in place before decorating
Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail, by someone who knows the system.
Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small compared with dozens found at once.
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Plastic pipes whose detail calls for a collar or wrap
- Signing off or certifying a building’s fire stopping
- Reviewing a building’s overall fire safety
Not sure which it is? You can call 01277 525 020 or email us and we’ll tell you honestly.

Questions about Lower Swanwick
Is Park Gate Business Centre, near Lower Swanwick, within your area?
Yes. Our area takes in Lower Swanwick and its surroundings, with estates and business parks such as Park Gate Business Centre included. Send details of the unit and the work through our quote form for a quick quote.
Is Lower Swanwick too small for you to travel to?
Not at all. Lower Swanwick is within our area. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
How long does a typical visit take?
That varies with the scale of the job, but the work usually takes a single visit for a short list of penetrations, or a phased programme for a whole building. For bigger or phased jobs, we’ll set out a timescale with the quote.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
What’s the quickest route to a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
Do you guarantee your work?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
What changes on 2 September 2029?
From 2 September 2029, Approved Document B in England drops its references to BS 476 classes, subject to the Government’s transitional arrangements. The European route, BS EN 13501-2, then applies. Your designer will choose products with the right evidence.

Where services cross fire walls in Lower Swanwick
In England, Approved Document B covers fire stopping of openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail. Central London is about 67 miles from Lower Swanwick. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal.
For an estates team at a campus like Solent University, 4.8 miles west of Lower Swanwick, summer M&E works are typically followed by a round of penetration sealing. For a building at a site such as Park Gate Business Centre (1.5 miles south-east of Lower Swanwick), a check of penetration seals after each fit-out is good practice. For a building such as Church of St Leonard, new heating or data runs are the usual reason penetrations need sealing.

From enquiry to sign-off
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Rural sites near Lower Swanwick may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- 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.
- Foam, ordinary sealant and debris come out first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Getting the site ready
- Point out any areas we must not close
- Tell us your opening times and when work is allowed
- Confirm the product named in the specification
