Fire stopping for Oxted sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
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 each bead is tooled to a neat concave finish. For a site in Oxted, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- 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.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Warn occupants and staff about the work
- Clear stock, furniture or equipment away from the joints
- Share the asbestos register for older buildings

Fire stopping for commercial buildings in Oxted
We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance. The enquiries we see most involve service penetrations left open after M&E works and unsealed joints where partitions meet the slab, across joints between fire-resisting walls and floors, pipe penetrations and small duct penetrations where the tested detail allows. Whoever orders the work in Oxted, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around Oxted, penetration and linear seals tend to be one-building jobs. With the specification and photographs of the gaps, we can give a fixed quote and bring the right products.
We stand by our work with a 12-month guarantee. That covers our preparation and application.

General trades versus a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
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.

Common questions from Oxted clients
Is a hospital such as Foetal Alcohol Spectrum Disorders Clinic somewhere you can work?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Do you work in occupied care homes around Oxted?
Yes. We agree rooms and times with the manager and work a few areas at a time. We follow the home’s own procedures throughout.
Is fire stopping in Scotland covered by different guidance?
Our work covers Greater London, the South East and every Scottish council area. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance, with proprietary products tested for the end use.
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?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Do you have third-party installer accreditation for fire stopping?
No. We are not members of a third-party fire-stopping installer scheme. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. Where a client or main contractor requires a scheme member, we will say so right away rather than waste your time.
For managing agents and facilities managers
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Fire stopping around Oxted: how the place shapes the job
Oxted lies roughly 18 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. Fire stopping of openings and penetrations in England falls under Approved Document B. 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.
At a healthcare site like Foetal Alcohol Spectrum Disorders Clinic, 0.6 miles north of Oxted, new services through compartment walls are a constant, and each needs the specified seal. For a school such as Hazelwood School, penetration sealing fits best at the end of the summer works. Halls and meeting rooms at places like St Agatha's Hall sometimes gain new services, and any compartment wall crossed needs the specified seal.
Oxted is about 7 miles east of Redhill, in Surrey. Anywhere in RH8, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 379 places across Surrey fall within our area, including Oxted. For work in that direction, see our London page, about 18 miles away.

Landmarks near Oxted
Around Oxted, our work takes us to commercial buildings near Oxted School and Hurst Green Infant School and the streets around them.

Why deal with it now?
Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme which is why earlier is better. Small buildings around Oxted suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What we can’t put right
We check first that sealant really is the fix. It won’t put right:
- Approving the work on behalf of building control
- Construction that lacks the fire resistance the seal relies on
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If in doubt, give us a call on 01277 525 020 or send photos by email and we will say what we think.
What we seal
- Cable penetrations
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
Different surfaces, different methods
Linear joints
Head-of-wall gaps, slab edges and wall junctions are linear joints. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers.
Drylining partitions
Drylined fire walls are tested in a particular build-up. We check that the product’s detail covers that partition type and board thickness first.
