Fire-rated sealing for Marlow buildings
In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. Marlow is about 30 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.
Hotels such as Chequers Hotel (less than half a mile south of Marlow) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. At a university such as Buckinghamshire New University (Wycombe Campus), 3.9 miles north of Marlow, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.
Marlow is about 4 miles south of High Wycombe, in Buckinghamshire. Anywhere in SL7, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across Buckinghamshire, 308 places are covered, including Marlow. Sites around Reading have their own page, about 12 miles away.
Anyone looking for fire stopping in SL7 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. Streets here include Station Road, High Street and Willowmead Square, and sites on any of them can send details for a fixed quote. Marlow sits on or close to the A404 and B482, which helps when planning parking and deliveries for the job. Just outside Marlow, we also work in Bisham (1 mile south), Marlow Bottom (1 mile north), Burroughs Grove (1 mile north), Temple (2 miles south) and Little Marlow (2 miles north-east). Bigger towns within reach include High Wycombe (4 miles north), Chesham (12 miles north-east), Amersham (10 miles north-east), Beaconsfield (6 miles north-east), Chalfont St Peter (10 miles east) and Princes Risborough (11 miles north). Marlow is one of the busier places in Buckinghamshire, and its commercial and public buildings are all within our area.
What’s near Marlow
In Marlow, that means premises near Butcher's Tap and Sir William Borlase's Grammar School and the streets around them. There’s a railway station in Marlow itself: Marlow station. Well-known places in the area include Eden (4 miles north) and High Wycombe Castle (4.1 miles north). Green spaces nearby include Carpenter's Wood.
Fire stopping in Marlow, done properly
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. Those on your schedule are closed with the specified product. We work on cable penetrations, service gaps in risers and joints between fire-resisting walls and floors, and the failures we’re asked to look at most are unsealed joints where partitions meet the slab and seals that don’t match their tested detail. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Marlow, that means joint design, primers and backing rod as standard.
Older buildings in towns like Marlow have often been rewired and replumbed several times, and each change can leave unsealed holes in walls and floors. Intumescent or fire-rated sealant is used wherever the specification asks for it, built up exactly as tested.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Our process
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Most work in Marlow is one building at a time: a school, a unit, an office or a block. We start with your photos, drawings or a site visit, then send a fixed quote.
- We start with your penetration schedule, drawings or specification.
- 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 first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Getting the site ready
- Send asbestos survey details if the building is pre-2000
- Explain the parking and delivery arrangements
- Move anything stored against the joints

When it isn’t the sealant
Being straight saves everyone time. Fresh joints won’t solve:
- Walls or floors that aren’t fire-resisting to begin with
- Fire doors, dampers or other fire safety equipment
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If you are not sure, just give us a call on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Service gaps in risers
- Cable penetrations
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
Looking after the joints
Your facilities or cleaning team can help the joints last. Share these points with them:
- Treat an open penetration as a priority repair
- Check risers and ceiling voids after each round of works
- Ask which product is in place before decorating
- Agree the fire-stopping specification before services go in
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.
Do you need fire stopping in Marlow?
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint, and a product not tested for that movement may crack. The tested detail for a linear joint states the width and movement it covers.
Typical triggers for a call:
- Unsealed penetrations discovered above suspended ceilings
- Fire sealant pulled out of the opening
- Seals that don’t match their tested detail
- Fire seals cut back for extra cables and never reinstated
On a site such as Globe Business Park, which lies east of Marlow, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.
Questions to ask before you book
- Who will actually carry out the work
- Their public liability cover
- Whether old or failed sealant will be cut out, not overlaid
- How they’ll work around occupants
How the job changes by surface
Masonry and concrete
Block walls and concrete floors are common substrates for penetration seals. Dust and loose debris are cleared out of the opening, with backing added if the detail requires it.
Risers and ceiling voids
Service risers and the voids above ceilings are where openings collect. Access is often tight, so we agree it with you in advance.
Marlow: questions and answers
Would you work within a site like Marlow Community Hospital?
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.
Will you plan work around the academic year at somewhere like Buckinghamshire New University (Wycombe Campus)?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Is BS 476 being phased out?
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, with clause 2.1.14 covering service penetrations.
Can you fire stop behind the services contractors?
Yes, where there is a specification for those walls and floors. Openings left by new services are among the most common jobs we see.
Do you need to see the site first?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
What do you charge?
It depends on the job: quantities, access, the product and any phasing. Call for a quote.

Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
