About our fire stopping in South Town
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on linear gaps at wall heads, small duct penetrations where the tested detail allows and pipe penetrations, and what we are called in for most is unsealed joints where partitions meet the slab and service penetrations left open after M&E works. Whoever orders the work in South Town, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For a smaller site near South Town, we plan to do all the penetrations in one go, with the specification and photos sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

FAQs: South Town
Is South Town too far out for you?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Is a hospital such as Alton Community Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is your workmanship covered by a guarantee?
Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.
Can you seal any opening with fire-rated sealant?
No. It depends on the tested detail for that wall or floor and service. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards.
Will you come and look before quoting?
It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it.
Do you certify or sign off fire stopping?
No. Sign-off belongs to the designer or building control, not the installer. We’ll confirm the product and detail installed, and you can tell us what other records you need at quote stage.
Honest limits
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Plastic pipes whose detail calls for a collar or wrap
- Issuing fire ratings or certificates for seals
- Construction that lacks the fire resistance the seal relies on
If you are not sure, just call 01277 525 020 or email the details over and we will give you a straight answer before you book.
Joints and surfaces we work on
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Cable penetrations
- Service gaps in risers
- Pipe penetrations
On site: what to expect
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes anything from one day to a planned run of visits, depending on the number of seals and the access, and our waste is bagged and taken away as we go. If others near South Town need work, visits can be combined. You will have a fixed quote before work starts.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- 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.
- We tell you about openings that need a different product.
What we need from you
- Point out parking and an unloading spot
- Make sure the joints can be reached
- Send your site hours and access windows

Advice
For managing agents and facilities managers
Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Maintenance after handover
Regular inspection catches problems early. In particular:
- Ask the designer to confirm details early on refits
- Foam or ordinary sealant is never a fire-seal repair
- Include service cupboards in routine inspections
- Arrange inspection before areas are covered up
Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.
On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts.
Where services cross fire walls in South Town
For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. South Town lies roughly 49 miles out from central London. 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.
Wherever services are added at a hospital such as Alton Community Hospital, 3.4 miles east of South Town, the compartment line has to be made good with the specified product. Holiday works at schools like Medstead Church of England Primary School often leave service openings to seal before pupils return.
South Town is about 4 miles west of Alton, in Hampshire. Any commercial site in South Town is covered. 723 places across Hampshire fall within our area, South Town among them. For work in that direction, see our Southampton page (20 miles or so).

What else we do in South Town
How the job changes by surface
Cables and cable bundles
Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. The detail limits bundle size and the gaps between and around cables and we work within those limits.
Plastic pipes
Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail, and we won’t substitute it for a specified collar.
Common problems we fix in South Town
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint, and a product not tested for that movement may crack. Linear joint details set a width range and movement capability, and the seal has to sit within them.
Any of the following is a good reason to get the joints checked over:
- Head-of-wall gaps with no fire seal
- Service penetrations left open after M&E works
- Builders’ foam or ordinary silicone in compartment walls
- Fire-rated sealant that has cracked or shrunk back
For a building such as Church of St Andrew, new heating or data runs are the usual reason penetrations need sealing.
