Fire stopping for businesses in Findon Valley

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Fire stopping in Findon Valley

On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, give us a call on 01277 525 020 or email drawings and photos with the schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. The enquiries we see most involve penetration schedules that need working through and seals that don’t match their tested detail, across small duct penetrations where the tested detail allows, service gaps in risers and cable penetrations. Searching for sealant specialists in Findon Valley? We have been sealing commercial buildings since 2005.

Converted and extended buildings around places like Findon Valley can mix old and new construction, so the wall or floor a service passes through isn’t always what the drawings assume. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Site staff or a sealant specialist?

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.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Why deal with it now?

Open penetrations multiply: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small and avoids a much larger catch-up later. In a smaller place such as Findon Valley, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Common questions from Findon Valley clients

Do you cover business parks and estates near Findon Valley, such as Downlands Business Park?

Yes. Estates, retail parks and business parks around Findon Valley, Downlands Business Park among them, are all within reach. Photos and a short description are enough for a first look.

Is Findon Valley too small for you to travel to?

Not at all. Findon Valley is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

What does an EI 60 rating mean?

In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. An EI 60 seal kept its integrity and insulation for 60 minutes as tested and the installation has to match the test.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Do you approve fire stopping for building control?

No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. Our part is fitting the specified product to its tested detail.

How many days will you need on site?

The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.

Is sealant suitable for all service openings?

No. Sealant is the right product only where the tested detail says so. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we flag those rather than improvise.

Work for main contractors and building owners

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 will confirm with the quote.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Fire-rated sealing for Findon Valley buildings

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. Either way, we install the specified product to its tested detail. Central London is about 47 miles from Findon Valley. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product.

Older community buildings such as All Saints that have been rewired or given new heating can have service gaps through walls worth checking against the specification. For a hotel such as Findon Manor Hotel, 1.1 miles north of Findon Valley, penetration seals are worth checking after any refit or services upgrade.

When it isn’t the sealant

Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:

  • Fire doors, dampers or other fire safety equipment
  • Writing the fire-stopping specification
  • Construction that lacks the fire resistance the seal relies on

If in doubt, call 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

Where we work in Findon Valley

  • Joints between fire-resisting walls and floors
  • Small duct penetrations where the tested detail allows
  • Linear gaps at wall heads
  • Service gaps in risers
  • Pipe penetrations
  • Cable penetrations

From enquiry to sign-off

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work normally takes a single visit for a short list of penetrations, or a phased programme for a whole building. Several jobs near Findon Valley can be grouped on one trip. Tell us your site hours and we will plan around them.

  1. The specification and schedule come first, so we know which details apply.
  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. Unsuitable material is removed and the opening cleaned 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.

Before we start on site

  • Agree which areas must stay open
  • Send any specification or drawings in advance
  • Make sure the joints can be reached

Advice

When to call us in Findon Valley

Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.

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
  • Openings left by services added after handover
  • Snag lists that include open service penetrations

Hospital estates such as Worthing Hospital, 2.9 miles south-east of Findon Valley, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

What your quote should include

  • What the guarantee covers, and for how long
  • How the joint faces will be prepared and primed
  • Their plan for phasing and protecting the area
  • How joint depth will be controlled
