Photos, a specification or a quick description of the joints is enough to start a fixed quote.
How we handle fire stopping in Newnham Murren
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. If you have hidden openings found during inspections and seals that don’t match their tested detail, we can put it right. Looking for mastic applicators who cover Newnham Murren? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Smaller places such as Newnham Murren still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Work we carry out in Oxfordshire comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or email us and we’ll arrange a return visit.

After the work
Regular inspection catches problems early. In particular:
- Look above ceilings when tiles are lifted for other jobs
- Ask which product is in place before decorating
- Have penetrations checked while they can still be seen
- Flag new cables with no seal around them
After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.
Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate, and it helps at inspections.
Why act early in Newnham Murren
An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail, and doing it once, properly, is cheaper. For buildings around smaller places like Newnham Murren, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

From enquiry to sign-off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Newnham Murren are usually planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Share your working hours and any access restrictions
- Warn occupants and staff about the work
- Have the specification and drawings to hand

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

What we are called out for in Newnham Murren
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint. 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:
- Builders’ foam or ordinary silicone in compartment walls
- Unsealed penetrations discovered above suspended ceilings
- Damaged fire seals in risers and voids
- Old intumescent sealant that has split away
Schools such as Crowmarsh Gifford Church of England School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.
Before you book anyone
- Are they CHAS accredited or on Constructionline?
- How they handle RAMS and site documents
- The terms of the workmanship guarantee
- Is the sealant right for the movement and the substrate?
Honest limits
Before quoting, we check that sealant is the right answer. It won’t put right:
- Openings that need collars, wraps, batts or boards rather than sealant
- Issuing fire ratings or certificates for seals
- Writing the fire-stopping specification
Not sure which it is? You can call 01277 525 020 or email us and we’ll tell you honestly before you book.
Surfaces we seal
- Linear gaps at wall heads
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
Fire stopping in Newnham Murren: the local picture
In England, Approved Document B covers fire stopping of openings and penetrations. 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. What we install is set by the specification, and it goes in to the tested detail. Newnham Murren lies roughly 44 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.
Hotels like George Hotel (to the north-west of Newnham Murren) are refurbished in phases, and each phase can open up compartment walls. For a unit at a site such as Hithercroft Industrial Estate, 1 mile to the west of Newnham Murren, new power or data runs between office and warehouse can breach a compartment wall.

It doesn’t need to be a full survey. A few details are enough to get going:
- Any specification or named product
- Drawings or a marked-up plan, if available

Your questions answered
Is a hospital such as Wallingford Community Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What does the BS 476 change mean for fire-rated sealant in Newnham Murren?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Can the building stay open while you work?
In the majority of cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
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.
How long will the new sealant last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
