Fire stopping for Chiddingly sites

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

Fire stopping for commercial buildings in Chiddingly

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. Each seal follows the manufacturer’s tested detail, not a rule of thumb. If you have fire sealant pulled out of the opening and non-fire-rated filler around services, we can help, on small duct penetrations where the tested detail allows, cable penetrations and service gaps in risers alike. A specialist sealant contractor works differently from a general builder: on jobs in Chiddingly, preparation and product choice get the time they need.

Smaller places such as Chiddingly still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

A 12-month guarantee applies to all our work. If an installation problem shows up, give us a call on 01277 525 020 or email the details over and we will arrange a return visit.

When to call us in Chiddingly

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in.

Any of the following is a good reason to get the joints checked over:

  • Seals that don’t match their tested detail
  • Open linear gaps along the top of fire-resisting walls
  • Non-fire-rated filler around services
  • Seals disturbed by maintenance and left open

Hospital estates such as Hellingly Hospital Railway (3.1 miles south-east of Chiddingly) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

Before you book anyone

  • How the joint faces will be prepared and primed
  • Will failed sealant be removed rather than covered?
  • Who will actually carry out the work
  • Proof of insurance

How to choose a sealant contractor

Cost factors for service penetrations

There’s no standard rate for sealant work, because every site is different. What we look at:

  • How much existing material needs removing
  • Quantities, in metres or numbers
  • Backing rod, priming and other preparation
  • Induction, permit and paperwork requirements

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.

Sending details for a quote

However big the job, the same details help:

  • Approximate linear metres or a joint schedule
  • The site address and postcode
  • The product your specification calls for
  • When you need the work done

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Should maintenance staff do it?

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Compartment walls and floors in Chiddingly

Chiddingly lies roughly 43 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls. Fire stopping of openings and penetrations in England falls under Approved Document B. 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. Our part stays the same: the specified product, installed to its tested detail.

Tenant changes at parks like Oakwood Business Park, 1.1 miles to the south of Chiddingly, bring new data and services, and openings through fire-resisting walls need the specified seal. In a school such as Chiddingly Primary School, fire-rated sealant goes in around service penetrations where it is specified.

Questions we’re asked in Chiddingly

Is Chiddingly too small for you to travel to?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

What happens to BS 476 references for fire stopping in Chiddingly?

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.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

Are you fully insured?

Yes. We’re fully insured, and the certificate can go with your quote.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day.

Diagnose, treat, sign off

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. Jobs in and around smaller places like Chiddingly are typically planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

What we need from you

  • Tell us your opening times and when work is allowed
  • For older buildings, check the asbestos register before work
  • Confirm the product named in the specification
