How we handle fire stopping in Welling
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. If you have openings found when ceilings come down for a refit and seals that don’t match their tested detail, we can put it right. For commercial sealant work in Welling, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we will confirm with the quote.
Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

When it isn’t the sealant
Some faults sit outside our scope, and we say so rather than covering them up:
- Deciding what a wall or floor needs, which belongs to the designer
- Gaps in walls that were never built as compartment walls
- Large openings beyond what any sealant detail covers
If in doubt, phone 01277 525 020 or send details through our quote form and we’ll say what we think.
Surfaces we seal
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Cable penetrations
- Linear gaps at wall heads
- Service gaps in risers
Leave it or put it right?
A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
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.

Common questions from Welling clients
Do you seal service penetrations in hotels around Welling?
Yes, where fire-rated sealant is the specified product. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
Will you take on work at estates like Old Bexley Business Park, close to Welling?
Yes. Estates, retail parks and business parks around Welling, Old Bexley Business Park among them, are all within reach. Photos and a short description are enough for a first look.
Can the sealant be colour-matched?
That depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Are you CHAS accredited?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Can you work while the building is occupied?
Normally, yes. We phase the work so most of the building stays in use.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
How long will the new sealant last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Compartments and services around Welling
Welling has a number of hotels close by, all within 2 miles. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. The 2 miles around Welling include four care or nursing homes. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail.
On a hospital site such as Memorial Hospital, 2.1 miles west of Welling, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. Colleges such as Rose Bruford College (1.4 miles south of Welling) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. Tenant changes at centres like Broadway Shopping Centre (1.6 miles east of Welling) often mean new services through walls between units.

Different surfaces, different methods
Metal pipes
Metal pipes conduct heat, so their details often call for extra measures along the pipe, and some details add wrapping or a set length of insulation. If the detail needs something beyond sealant, we tell you.
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. Each gap is measured where it is widest so we know it sits within the tested range.
Our process
We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it.
