Fire stopping across Southwood
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
When to bring in a specialist
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Fire stopping in Southwood, done properly
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate and we’d rather say that up front. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you are dealing with non-fire-rated filler around services and head-of-wall gaps with no fire seal, we can help, whatever the surface. For commercial sealant work in Southwood, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
In places the size of Southwood, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

When it isn’t the sealant
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Signing off or certifying a building’s fire stopping
- Deciding what a wall or floor needs, which belongs to the designer
- Reviewing a building’s overall fire safety
Not sure which it is? You can phone 01277 525 020 or use the quote form and we will tell you honestly before you book.
What we seal
- Cable penetrations
- Linear gaps at wall heads
- Service gaps in risers
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
Leave it or put it right?
The longer openings stay, the more there tend to be: each new service adds to the list. Keeping on top of it after each round of works keeps the job small. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Why appoint us
- Clear, fixed quotes
- Joints cleaned back to sound surfaces
- CHAS accredited
- Fully insured, including public liability cover
Southwood: questions and answers
Can work at a site such as Farnborough College of Technology fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you seal penetrations in a hotel in Southwood after a refit?
Yes, where fire-rated sealant is the specified product. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
Do you work in Southwood?
Yes. We take on work across Southwood.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Penetration seals near Southwood
Southwood is about 34 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal. For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. We install whatever has been specified, to the product’s tested detail.
Halls and meeting rooms at places like St John the Baptist sometimes gain new services, and any compartment wall crossed needs the specified seal. Tenant changes at parks like Southwood Business Park, under half a mile to the east of Southwood, bring new data and services, and openings through fire-resisting walls need the specified seal. For a site team at a college like Farnborough College of Technology, 2.1 miles to the east of Southwood, fire-rated sealing is best scheduled after the summer works.

How a job runs
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area.

Different surfaces, different methods
Linear joints
Joints at the top of partitions may need to move as the slab above deflects. We use the product and backing the detail names for that movement.
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.
