How we handle fire stopping in Thursley
No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. The enquiries we see most involve unsealed openings around new pipes and cables and seals that don’t match their tested detail, on small duct penetrations where the tested detail allows, service gaps in risers and cable penetrations. Whoever orders the work in Thursley, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places like Thursley, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or email drawings and photos and we will come back to it.

Questions we’re asked in Thursley
How does the move away from BS 476 affect penetration seals in Thursley?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Is Thursley too far out for you?
No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Can staff carry on working while you’re here?
Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.
How long does a job like this take?
That varies with the scale of the job, though a typical visit typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

What else we do in Thursley
Commercial clients in Thursley
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Thursley can sit alongside others in a wider programme across Surrey.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Keeping the joints sound
For the best life from the joints:
- Get seals inspected before ceilings and boxing close
- Leave fire sealant to cure fully before covering it
- Ask the designer to confirm details early on refits
- Treat an open penetration as a priority repair
New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.
Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.
How the job changes by surface
Small ducts
Ducts are only sealed with sealant where the detail allows it. Dampers and ductwork systems themselves are outside our work.
Linear joints
Joints at the top of partitions may need to move as the slab above deflects. The specified product and backing for that movement are what goes in, with no gaps along the run.
On site: what to expect
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. Smaller jobs around Thursley can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- We read the specification, drawings or penetration schedule you send.
- 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.
- We fit the backing the detail asks for, to the stated depth.
- 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.
Before we start on site
- Arrange parking or a loading space
- Flag any permit to work we’ll need
- Clear stock, furniture or equipment away from the joints
Getting a fixed quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.
Related advice
Common problems we fix in Thursley
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps, and a product not tested for that movement may crack. Linear joint details set a width range and movement capability, and the seal has to sit within them.
Any of the following is a good reason to get the joints checked over:
- Open linear gaps along the top of fire-resisting walls
- Seals that don’t match their tested detail
- Unsealed openings around new pipes and cables
- Non-fire-rated filler around services
For a building such as Church of St Michael and All Angels, new heating or data runs are the usual reason penetrations need sealing.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- How joint depth will be controlled
- Proof of insurance
- How long is the guarantee, and what does it include?
