About our fire stopping in Kingsfold

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. The enquiries we see most involve openings found when ceilings come down for a refit and head-of-wall gaps with no fire seal, across small duct penetrations where the tested detail allows, service gaps in risers and pipe penetrations. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Kingsfold it comes down to the same thing: the right product in a properly prepared joint.

Smaller places such as Kingsfold 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.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Compartment walls and floors in Kingsfold

Central London is about 28 miles from Kingsfold. 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. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Either way, we install the specified product to its tested detail.

On a hospital site such as Horsham Hospital, 3.2 miles south of Kingsfold, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. Office fit-outs on sites such as Northlands Business Park, 1.7 miles to the west of Kingsfold, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

Kingsfold is about 3 miles north of Horsham, in West Sussex. We send applicators to Kingsfold for service penetrations, handled exactly as we handle every other area. Kingsfold is one of 373 places we cover in West Sussex for service penetrations. For work in that direction, see our Brighton page.

We also cover Paynes Green (2 miles north-west), Capel (2 miles north), Ockley (3 miles north-west), Forest Green (4 miles north-west) and Beare Green (4 miles north). A short drive away, we cover Crawley (6 miles east), Horsham (3 miles south), Haywards Heath (13 miles south-east), Burgess Hill (14 miles south-east), East Grinstead (14 miles east) and Broadfield (6 miles east).

What affects the price in Kingsfold

The price varies from site to site. Expect it to depend on:

  • The product specified
  • Distance, for remote addresses
  • Removal of failed or old sealant
  • Any access equipment needed

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What to include in your enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • Any dates the work must fit around
  • Asbestos survey details if the building is older
  • Whether the building will be occupied during the work
  • Drawings or a marked-up plan, if available

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 photographs and a few notes.

From enquiry to sign-off

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. If others near Kingsfold need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Getting the site ready

Commercial clients in Kingsfold

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

General trades versus a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Common questions from Kingsfold clients

Can you work on a hospital site such as Horsham Hospital?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you cover business parks and estates near Kingsfold, such as Northlands Business Park?

Yes. Our area takes in Kingsfold and its surroundings, with estates and business parks such as Northlands Business Park included. Send details of the unit and the work through our quote form for a quick quote.

Is the work guaranteed?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Do you certify or sign off fire stopping?

No. Sign-off belongs to the designer or building control, not the installer. We’ll confirm the product and detail installed, and you can tell us what other records you need at quote stage.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Looking after the joints

Regular inspection catches problems early. In particular:

  • Agree the fire-stopping specification before services go in
  • Foam or ordinary sealant is never a fire-seal repair
  • Have penetrations checked while they can still be seen
  • Put resealing into every M&E and fit-out package

Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original, or a new specification from the designer.

On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.

What happens if it’s left?

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach and each detail can be checked as we go. Converted and older buildings near places like Kingsfold tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
