Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Settle who seals which penetrations at the start of a project
- Look above ceilings when tiles are lifted for other jobs
- Treat an open penetration as a priority repair
- Have penetrations checked while they can still be seen
Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way, or a new specification from the designer.
Ask every contractor who works in risers or voids to report openings they create. It costs little and catches breaches early.
Fire stopping in Sandford St Martin, done properly
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, ring 01277 525 020 or send photos by email with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we’ll confirm with the quote. We work on joints between fire-resisting walls and floors, pipe penetrations and small duct penetrations where the tested detail allows, and the failures we’re asked to look at most are improvised or mixed-product fire seals and expanding foam used as fire stopping. For commercial sealant work in Sandford St Martin, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Barn and farm-building conversions near places like Sandford St Martin often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
A 12-month guarantee applies to all our work in Oxfordshire. Should something we installed fail, call 01277 525 020 or send photos by email and we will come back to it.

Penetration seals near Sandford St Martin
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 Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Central London is about 63 miles from Sandford St Martin. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product.
For a unit at a site such as Enstone Airfield Industrial Estate, which lies west of Sandford St Martin, new power or data runs between office and warehouse can breach a compartment wall.

What we’re called out for in Sandford St Martin
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.
What tends to prompt an enquiry:
- Damaged fire seals in risers and voids
- Head-of-wall gaps with no fire seal
- Improvised or mixed-product fire seals
- Unsealed penetrations discovered above suspended ceilings
For a building such as Church of St Martin, new heating or data runs are the usual reason penetrations need sealing.

On site: what to expect
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Sandford St Martin are usually planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Preparing the site
- Tell us your opening times and when work is allowed
- Have the specification and drawings to hand
- For older buildings, check the asbestos register before work

What else we do in Sandford St Martin
Why it’s worth doing now in Sandford St Martin
Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed which is why earlier is better. One visit to deal with every failing joint makes more sense than several trips to a place like Sandford St Martin, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

Should maintenance staff do it?
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Writing the fire-stopping specification
- Openings that need collars, wraps, batts or boards rather than sealant
- Issuing fire ratings or certificates for seals
If you’re not sure, just phone 01277 525 020 or email us and we will give you a straight answer before you book.
Joints and surfaces we work on
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Linear gaps at wall heads
- Cable penetrations
- Joints between fire-resisting walls and floors
- Service gaps in risers
