How we handle fire stopping in Henley-on-Thames
It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance in Henley-on-Thames and nearby. If you have penetration schedules that need working through and old intumescent sealant that has split away, we can help, whatever the surface. Most enquiries from Henley-on-Thames start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Buildings in a smaller place such as Henley-on-Thames that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.
Every job we finish is backed by a 12-month workmanship guarantee, 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
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:
- Issuing fire ratings or certificates for seals
- Deciding what a wall or floor needs, which belongs to the designer
- Walls or floors that aren’t fire-resisting to begin with
If in doubt, ring 01277 525 020 or email drawings and photos and we’ll say what we think before you book.
What we seal
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Linear gaps at wall heads
- Cable penetrations
- Service gaps in risers
Compartments and services around Henley-on-Thames
Henley-on-Thames is about 35 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. 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.
For an estates team at a campus like University of Reading, 2.9 miles south of Henley-on-Thames, summer M&E works are usually followed by a round of penetration sealing. Older community buildings such as Holy Trinity Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Nearby you will also find Frazer Nash Archives (0.5 miles south-east). Open spaces near Henley-on-Thames include Sonning Hill and Hurley Chalk Pit.
After the work
Your facilities or cleaning team can help the joints last. Share these points with them:
- Treat an open penetration as a priority repair
- Ask which product is in place before decorating
- Don’t let anyone top up a fire seal with the wrong product
- Brief every trade that openings they make must be sealed
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown, and report them promptly.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job; found late, it can be one of many.
What sets the cost
Quotes vary with the job. Expect it to depend on:
- Induction, permit and paperwork requirements
- Location, for remote and island sites
- Joint width, depth and condition
- Quantities, in metres or numbers
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.
Details that help us quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Rough lengths or quantities, or drawings if you have them
- Any dates the work must fit around
- Any specification or named product
- Asbestos survey details if the building is older
Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. If you have questions first, speak to us on 01277 525 020 or email a schedule or drawings.
When to call us in Henley-on-Thames
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps, and a product not tested for that movement may crack. The tested detail for a linear joint states the width and movement it covers.
If one of these sounds familiar, it’s time for a closer look:
- Hidden openings found during inspections
- Improvised or mixed-product fire seals
- Fire seals cut back for extra cables and never reinstated
- Unsealed joints where partitions meet the slab
In a hotel such as Imperial Hotel And Associated Buildings, which lies north-east of Henley-on-Thames, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.
What to look for in a quote
- How long is the guarantee, and what does it include?
- Will failed sealant be removed rather than covered?
- How the joint faces will be prepared and primed

Questions about Henley-on-Thames
What does the BS 476 change mean for fire-rated sealant in Henley-on-Thames?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Can you seal around new services in a hotel near Henley-on-Thames?
Yes, where the specification calls for fire-rated sealant. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
Do you need to see the site first?
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.
How much does the work cost?
Each job is quoted on its own details. For yours, give us a call on 01277 525 020 or use the quote form.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. If neighbouring businesses or buildings around Henley-on-Thames need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.
- We read the specification, drawings or penetration schedule you send.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
What we need from you
- Have the specification and drawings to hand
- Explain the parking and delivery arrangements
- Agree which areas must stay open

What the job involves on each surface
Metal pipes
Sealant details often cover copper and steel pipework. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail and we confirm each before sealing.
Cables and cable bundles
New data and power cables are the most common breach we see. Openings around new cables are resealed to the detail.
