Fire stopping in Moulsford
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate and we’d rather say that up front. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on cable penetrations, service gaps in risers and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are head-of-wall gaps with no fire seal and openings found when ceilings come down for a refit. A specialist sealant contractor works differently from a general builder: in Moulsford, that means joint design, primers and backing rod as standard.
A job near Moulsford is typically planned around one visit, with the specification and photographs 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. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

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 one of these:
- Large openings beyond what any sealant detail covers
- Deciding what a wall or floor needs, which belongs to the designer
- Issuing fire ratings or certificates for seals
Not sure which it is? You can call the office on 01277 525 020 or email the details over and we’ll tell you honestly before you book.
What we seal
- Service gaps in risers
- Cable penetrations
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Small duct penetrations where the tested detail allows

Common questions from Moulsford clients
Is Moulsford too small for you to travel to?
Not at all. Moulsford is within our area. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Do you decide the fire-stopping details for buildings in Moulsford?
No. The designer or fire engineer sets the detail and building control accepts it. Our part is installing the specified product to its tested detail, and telling you if the detail calls for something other than sealant.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Do you guarantee your work?
Yes. Workmanship is guaranteed for 12 months on every job.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Can staff carry on working while you’re here?
In most cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Work for main contractors and building owners
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.
Penetration seals near Moulsford
Approved Document B is the English guidance that covers fire stopping around 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. Central London is about 46 miles from Moulsford. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.
In a school such as Cranford House School, fire-rated sealant goes in around service penetrations where it is specified. In a building such as Church of St John the Baptist, any service penetration through a fire-resisting wall should be sealed to the specified detail.
Moulsford is about 6 miles south-east of Didcot, in Oxfordshire. We cover commercial sites throughout Moulsford, for single jobs and planned programmes alike. Moulsford is one of 423 places we cover in Oxfordshire. For work in that direction, see our Reading page, about 10 miles away.

Why act early in Moulsford
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is typically a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. One visit to deal with every failing joint makes more sense than several trips to a place like Moulsford, rather than one at a time. Photos of every joint help us quote for the whole job.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Surface 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.
Drylining partitions
Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers.
Maintenance after handover
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Arrange inspection before areas are covered up
- Treat an open penetration as a priority repair
- Check risers and ceiling voids after each round of works
- Brief every trade that openings they make must be sealed
Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted.
Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.
