How we handle fire stopping in Upton
A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. We work on cable penetrations, small duct penetrations where the tested detail allows and service gaps in risers, and the usual reasons a site gets in touch are builders’ foam or ordinary silicone in compartment walls and unsealed joints where partitions meet the slab. Whoever orders the work in Upton, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places like Upton, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Owners, agents and contractors
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

What else we do in Upton
What sealant work can’t fix
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Walls or floors that aren’t fire-resisting to begin with
- Large openings beyond what any sealant detail covers
Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we will tell you honestly before you book.
What we seal
- Pipe penetrations
- Linear gaps at wall heads
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Joints between fire-resisting walls and floors
Your questions answered
Is a smaller place like Upton outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Is hospital work, at somewhere like St John's Hospital, something you do?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
Is the BS 476 change in 2029 relevant to fire stopping?
It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence, subject to transitional arrangements. Scotland follows its own Technical Handbook, including clause 2.1.14 on service penetrations.
What does an EI 60 rating mean?
The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. An EI 60 seal kept its integrity and insulation for 60 minutes as tested; installing to the detail is what carries that across to site.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Quoting for work in Upton
Before we quote, we look at:
- Removal of failed or old sealant
- Location, for remote and island sites
- The total length or number of joints
- The size and state of each joint
The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote when you’re ready.
What we need to price the job
A good diagnosis starts with the right details. Tell us:
- Photos of the joints, close up and from further back
- Rough lengths or quantities, or drawings if you have them
- Where the site is, with the postcode
- The type of building and who uses it
Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to call the office on 01277 525 020 or email us.
On site: what to expect
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. If others near Upton need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Share the asbestos register for older buildings
- Tell us what induction or permit system the site runs
- Tell us which areas need to stay in use
Getting a fixed quote
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
Advice
What the job involves on each surface
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range, and any outside it are raised with you.
Drylining partitions
Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers before sealing.
Service penetrations in Upton buildings
For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Upton lies roughly 40 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product.
For an estates team at a campus like University Campus Aylesbury Vale, 3.3 miles to the east of Upton, summer M&E works are usually followed by a round of penetration sealing. Older community buildings such as Church of Saints Peter and Paul that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
Upton is about 3 miles south-west of Aylesbury, in Buckinghamshire. Businesses, contractors and managing agents in Upton can call on us for service penetrations. 308 places across Buckinghamshire fall within our area, including Upton. There’s a separate page for Oxford, about 15 miles away.

What’s near Upton
We work on buildings around The Seven Stars Public House. The closest station to Upton is Aylesbury Vale Parkway station, roughly 2.5 miles north.

When to call us in Upton
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.
Clients usually get in touch after noticing one or more of the following:
- Fire seals cut back for extra cables and never reinstated
- Service penetrations left open after M&E works
- Non-fire-rated filler around services
- Old intumescent sealant that has split away
On a hospital site such as St John's Hospital (under half a mile north-east of Upton), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
