- Approving the work on behalf of building control

Fire stopping in Oakhanger, done properly
Most of our fire stopping work happens after the building is up. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. If you’re dealing with head-of-wall gaps with no fire seal and damaged fire seals in risers and voids, we can put it right, on linear gaps at wall heads, joints between fire-resisting walls and floors and cable penetrations alike. For commercial sealant work in Oakhanger, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Rural conversions around Oakhanger can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

What happens if it’s left?
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is normally a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Around Oakhanger, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What else we do in Oakhanger
When to bring in a specialist
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
Diagnose, treat, sign off
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. Smaller jobs around Oakhanger can be grouped with others nearby. You will have a fixed quote before work starts.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Make sure the joints can be reached
- For older buildings, check the asbestos register before work
- Let building users know which areas are affected

Advice
Oakhanger: questions and answers
Is Southlands Industrial Park, near Oakhanger, within your area?
Yes. Our area takes in Oakhanger and its surroundings, with estates and business parks such as Southlands Industrial Park included. Send details of the unit and the work through our quote form for a quick quote.
Can you take on a job at a hospital such as Chase Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How many days will you need on site?
It depends on the scope, though a typical visit normally takes anything from one day to a planned run of visits, depending on the number of seals and the access. For bigger or phased jobs, we’ll set out a timescale with the quote.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
What changes on 2 September 2029?
From 2 September 2029, Approved Document B in England drops its references to BS 476 classes, with transitional arrangements set by the Government. After that, the European classification under BS EN 13501-2 is the route. Your designer will choose products with the right evidence.

What the job involves on each surface
Plastic pipes
Plastic waste pipes through slabs come up often. The detail decides whether sealant alone is enough.
Risers and ceiling voids
Service risers and the voids above ceilings are where openings collect. Access to these areas is planned with you in advance, including keys, permits and any isolations.
Do you need fire stopping in Oakhanger?
Openings in fire-resisting walls normally appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.
Any of the following is a good reason to get the joints checked over:
- Openings found when ceilings come down for a refit
- Fire-stopping items raised at inspection or handover
- Seals disturbed by maintenance and left open
- Expanding foam used as fire stopping
Industrial units on estates such as Southlands Industrial Park, 0.7 miles south of Oakhanger, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.

Where services cross fire walls in Oakhanger
At about 44 miles from central London, Oakhanger is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. We install whatever has been specified, to the product’s tested detail.
In a building such as St Mary Magdalene's Church, any service penetration through a fire-resisting wall should be sealed to the specified detail. Holiday works at schools like Mill Chase Academy often leave service openings to seal before pupils return.
