Fire stopping in Timsbury
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. The enquiries we see most involve service penetrations left open after M&E works and seals that don’t match their tested detail, across cable penetrations, joints between fire-resisting walls and floors and service gaps in risers. Whoever orders the work in Timsbury, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Rural conversions around Timsbury can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

When to call us in Timsbury
Mixing products or improvising a detail breaks the link with the test evidence. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.
What tends to prompt an enquiry:
- Openings left by services added after handover
- Open linear gaps along the top of fire-resisting walls
- Fire sealant pulled out of the opening
- Fire-stopping items raised at inspection or handover
Where a unit on an estate such as Yokesford Hill Industrial Estate (1.1 miles south-east of Timsbury), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
Before you book anyone
- Their public liability cover
- Whether primer will be used where the manufacturer specifies it
- Their pre-qualification and accreditations
- Is the sealant right for the movement and the substrate?
Different surfaces, different methods
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, but many need a collar or wrap. We check the pipe material and diameter against the detail before we start.
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point so we know it sits within the tested range.
Penetration seals near Timsbury
Timsbury is about 69 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product. 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.
Wherever services are added at a hospital such as Romsey Hospital, 2.6 miles to the south-east of Timsbury, the compartment line has to be made good with the specified product. Older community buildings such as Church of St Andrew that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
Timsbury is about 3 miles north-west of Romsey, in Hampshire. Commercial clients in Timsbury use us for work on service penetrations. We work across 723 places in Hampshire. There’s a separate page for Southampton, about 9 miles away.

Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Signing off or certifying a building’s fire stopping
- Reviewing a building’s overall fire safety
If you’re not sure, just speak to us on 01277 525 020 or email us and we will give you a straight answer.
Surfaces we seal
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Cable penetrations
- Service gaps in risers
Cost factors for service penetrations
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- Travel to remote or island sites
- How much existing material needs removing
- Whether the work must be split into stages
- Specialist products, such as fire-rated or hygienic sealants
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.
Before you send an enquiry
The more we know, the firmer the quote. Helpful details to send:
- The asbestos register, for older buildings
- The product your specification calls for
- Drawings or a marked-up plan, if available
- What the building is and how it’s used
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.
Diagnose, treat, sign off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and our waste is bagged and taken away as we go. For a building around Timsbury, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- First we confirm the product and tested details named in the specification.
- 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.
- We gun the sealant in to the specified depth around each service and tool it.
- We walk the completed areas with you and confirm the records agreed at quote stage.
What we need from you
- Tell us which areas need to stay in use
- Point out parking and an unloading spot
- Send your site hours and access windows

Questions about Timsbury
Is Timsbury too small for you to travel to?
No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
What does the BS 476 change mean for fire-rated sealant in Timsbury?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Are you fully insured?
Yes. We are fully insured, including public liability cover.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
How long does a job like this take?
It depends on the scope, though a typical visit usually takes a single visit for a short list of penetrations, or a phased programme for a whole building. For bigger or phased jobs, we’ll set out a timescale with the quote.
How do we ask for a quote?
The quote form is the simplest route, though you can also phone 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Should maintenance staff do it?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
