Fire stopping near Filching

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Common problems we fix in Filching

Plenty of openings were simply never closed, often hidden above suspended ceilings or behind boxing. Inspections, refurbishments and ceiling access normally bring them to light.

Site and facilities staff are often the first to spot these:

  • Expanding foam used as fire stopping
  • Fire-rated sealant that has cracked or shrunk back
  • Unsealed penetrations discovered above suspended ceilings
  • Fire seals cut back for extra cables and never reinstated

Tenant changes at centres like Hampden Park Retail Park, 2.7 miles east of Filching, often mean new services through walls between units.

Before you book anyone

  • Which product they’ll use, and why it suits the joint
  • How they handle RAMS and site documents
  • Do they follow the manufacturer’s priming guidance?
  • Will failed sealant be removed rather than covered?

How to choose a sealant contractor

Fire stopping for commercial buildings in Filching

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal, not a rule of thumb. We work on pipe penetrations, service gaps in risers and joints between fire-resisting walls and floors, and the failures we’re asked to look at most are fire stopping installed outside its tested range and fire-stopping items raised at inspection or handover. One point of contact handles commercial sealant work in Filching from the first photographs to the final walk-round, whether it’s one building or several.

Rural conversions around Filching 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.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Cost factors for service penetrations

To price the job, we consider:

  • The total length or number of joints
  • Travel to remote or island sites
  • The size and state of each joint
  • How accessible the joints are

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Sending details for a quote

A few photos plus some basic facts will normally do. Please tell us:

  • Whether an asbestos survey exists
  • The postcode of the building
  • What the building is and how it’s used
  • Approximate linear metres or a joint schedule

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

What the job involves on each surface

Linear joints

Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed and the installation has to fit inside those limits.

Plastic pipes

Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail.

For managing agents and facilities managers

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Fire-rated sealing for Filching buildings

A 2-mile radius around Filching takes in several hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. In England, Approved Document B covers fire stopping of 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.

Where a unit on an estate such as Chaucer Industrial Estate, which lies north-east of Filching, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. At a university such as University of Brighton Eastbourne Campus, which lies south-east of Filching, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

Filching is about 3 miles north-west of Eastbourne, in East Sussex. Across the BN26 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Filching is one of 308 places in East Sussex on our list. For work in that direction, see our Brighton page, about 16 miles away.

We take on service penetrations across the BN26 postcode area, for business premises of every kind.

Filching: questions and answers

Is Filching too far out for you?

No. Places such as Filching are covered as much as the big towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Would you work within a site like Eastbourne District General Hospital?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

What site paperwork can you supply?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

What does an EI 60 rating mean?

Penetration seals are tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. Results are classified under BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. That rating only holds when the product is installed to its tested detail.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

How do I request a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

How many days will you need on site?

It depends on the scope, though a typical visit typically takes anything from one day to a planned run of visits, depending on the number of seals and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Our process

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes anything from one day to a planned run of visits, depending on the number of seals and the access, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Filching are typically planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out first.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • Agree which areas must stay open
  • Tell us your opening times and when work is allowed

Getting a fixed quote

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

When something else is needed

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Writing the fire-stopping specification
  • Signing off or certifying a building’s fire stopping

If in doubt, phone 01277 525 020 or email us and we’ll say what we think.
