Fire stopping near Anthill Common
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Leave it or put it right?
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is typically a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. For buildings around smaller places like Anthill Common, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

Fire stopping in Anthill Common
On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. Most enquiries involve service penetrations left open after M&E works and builders’ foam or ordinary silicone in compartment walls, on linear gaps at wall heads, pipe penetrations and cable penetrations. A specialist sealant contractor works differently from a general builder: in Anthill Common, that means joint design, primers and backing rod as standard.
For a smaller site near Anthill Common, we plan to do all the penetrations in one go, with the specification and photos sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Anthill Common: questions and answers
Is a hospital such as Queen Alexandra Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
What does the BS 476 change mean for fire-rated sealant in Anthill Common?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
How long does a job like this take?
It depends on the scope, but the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Do you work in Anthill Common?
Yes. Anthill Common is in our area and the rest of Hampshire, within our coverage of Greater London, South East England and Scotland. To discuss a job, call the office on 01277 525 020 or send photos by email.
Can you quote from photos?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
After the work
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Include service cupboards in routine inspections
- Foam or ordinary sealant is never a fire-seal repair
- Record which product was used where
After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.
Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate, which saves guesswork.
Where services cross fire walls in Anthill Common
At about 59 miles from central London, Anthill Common is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.
Hospital estates such as Queen Alexandra Hospital (4.2 miles south of Anthill Common) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Hotels like The George Hotel, 1.5 miles to the north of Anthill Common, are refurbished in phases, and each phase can open up compartment walls. Older community buildings such as Church of All Saints that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

What sealant work can’t fix
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Gaps in walls that were never built as compartment walls
- Approving the work on behalf of building control
- Fire risk assessments, a job for a competent assessor
If you’re not sure, just phone 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.
Surfaces we seal
- Pipe penetrations
- Cable penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Linear gaps at wall heads
Building owners, agents and FMs in Anthill Common
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Diagnose, treat, sign off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. If others near Anthill Common need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

- We sort the openings by the detail each one needs.
