Questions about Horsham
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Horsham?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Can work at a site such as The College of Richard Collyer fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Do you guarantee your work?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.
What hours do you work?
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.
Can the building stay open while you work?
Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
How we handle fire stopping in Horsham
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail, not a rule of thumb. We work on cable penetrations, service gaps in risers and linear gaps at wall heads, and the usual reasons a site gets in touch are openings found when ceilings come down for a refit and service penetrations left open after M&E works. A specialist sealant contractor works differently from a general builder: in Horsham, that means joint design, primers and backing rod as standard.
Office and retail refurbishments in a large town such as Horsham add new services through existing fire-resisting walls. Each new penetration needs closing with the product the specification calls for, and fire-rated sealant goes in to the product’s tested detail where that is what’s specified.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

General trades versus a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Common problems we fix in Horsham
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.
It’s worth sending us details if you spot any of the following:
- Builders’ foam or ordinary silicone in compartment walls
- Service penetrations left open after M&E works
- Unsealed penetrations discovered above suspended ceilings
- Unsealed joints where partitions meet the slab
For a building such as Hope Chapel, new heating or data runs are the usual reason penetrations need sealing.

Looking after the joints
After handover, these steps help:
- File the specified details where the next contractor can find them
- Keep general-purpose fillers away from compartment walls
- Look above ceilings when tiles are lifted for other jobs
- Have penetrations checked while they can still be seen
After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail, by someone who knows the system.
Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts.
Compartments and services around Horsham
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Horsham has eight care or nursing homes no more than 2 miles away. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. We install fire-rated sealant to the tested detail where it is specified.
Large healthcare estates like Horsham Hospital, less than half a mile to the north-west of Horsham, change their services often, so penetration seals are worth checking after M&E work. Hotels such as The King's Head Hotel, less than half a mile to the south-west of Horsham, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Owners, agents and contractors
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
What happens if it’s left?
Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down and each detail can be checked as we go. In a town the size of Horsham, traffic, footfall and weather keep working on a failed joint. Catching it early keeps the fix simple.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Diagnose, treat, sign off
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Sites in a big town such as Horsham frequently have reception sign-in, inductions and permits to work. Tell us about inductions, permits and site hours so the plan fits.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out first.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Getting the site ready
- Have the specification and drawings to hand
- Point out parking and an unloading spot
- Send asbestos survey details if the building is pre-2000
