About our fire stopping in Sidlow
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. If you’re dealing with fire-rated sealant that has cracked or shrunk back and improvised or mixed-product fire seals, we can help. For commercial sealant work in Sidlow, 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 Sidlow 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.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Questions we’re asked in Sidlow
Can you take on a job at a hospital such as East Surrey Hospital?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can work at a site such as Reigate College fit around teaching?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you guarantee your work?
Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.
Can you seal any opening with fire-rated sealant?
No. Sealant is the right product only where the tested detail says so. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards, and we flag those rather than improvise.
Is the BS 476 change in 2029 relevant to fire stopping?
For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications, though transitional rules apply. In Scotland, the Technical Handbook sets its own guidance.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
What will the job cost?
We don’t publish prices, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.
Fire stopping around Sidlow: how the place shapes the job
At about 21 miles from central London, Sidlow is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. Fire stopping of openings and penetrations in England falls under Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
Hospital estates such as East Surrey Hospital (1.9 miles north-east of Sidlow) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Holiday works at schools like Dovers Green School often leave service openings to seal before pupils return.

When to bring in a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Putting right a botched joint often costs more than sealing it well at the start, 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.
Signs you need fire stopping in Sidlow
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.
Most enquiries start with something like this:
- Old intumescent sealant that has split away
- Hidden openings found during inspections
- Unsealed openings around new pipes and cables
- Open linear gaps along the top of fire-resisting walls
Offices at parks like Fontigarry Farm Business Park, 0.7 miles south of Sidlow, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

On site: what to expect
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access, and we clear our waste as we work. If others near Sidlow need work, visits can be combined. A fixed quote is given before anything starts.

How the quote is worked out
We price every job individually. The main factors are:
- Distance, for remote addresses
- Working within restricted access windows
- Joint width, depth and condition
- Access and working height
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Before you send an enquiry
To price the job accurately, we need to understand the site. Useful things to include:
- Any specification or named product
- Your programme or deadline
- The asbestos register, for older buildings
- Drawings or a marked-up plan, if available
A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or phone 01277 525 020 or email drawings and photos to discuss it first.
How the job changes by surface
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed.
Plastic pipes
Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail.
