Fire stopping near Shelvin

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Why deal with it now?

The longer openings stay, the more there tend to be: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable. Older rural buildings around Shelvin move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Fire stopping in Shelvin

Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it, matching the product and detail it names. With no specification in place, the first step sits with your designer or fire engineer, not with us. We work on linear gaps at wall heads, joints between fire-resisting walls and floors and service gaps in risers, and the failures we’re asked to look at most are fire-stopping items raised at inspection or handover and builders’ foam or ordinary silicone in compartment walls. A single leaking joint is often how a building in Shelvin first comes to us: we look at the rest while we’re there and tell you what we find.

Around smaller places like Shelvin, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

What affects the price in Shelvin

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Whether old sealant has to be cut out first
  • Distance, for remote addresses
  • The site’s rules and procedures
  • How much there is to seal

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’ll have a fixed figure to work with.

Before you send an enquiry

Whether it’s one area or a whole building, the same details help:

  • Specification clauses that apply
  • Asbestos survey details if the building is older
  • The site address and postcode
  • The type of building and who uses it

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or email drawings and photos with what you know.

How the job changes by surface

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access to these areas is planned with you in advance along with any permits your site needs.

Linear joints

Joints at the top of partitions may need to move as the slab above deflects. We use the product and backing the detail names for that movement.

Our process

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself normally taking anything from one day to a planned run of visits, depending on the number of seals and the access. Jobs in and around smaller places like Shelvin are usually planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We read the specification, drawings or penetration schedule you send.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Tell staff and tenants when we will be in
  • Send your site hours and access windows

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Advice

Questions we’re asked in Shelvin

What does the BS 476 change mean for fire-rated sealant in Shelvin?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Is Shelvin too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

How many days will you need on site?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

Do you take on small jobs?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Can staff carry on working while you’re here?

In the majority of cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.

What will the job cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we’ll price it properly.

Fire stopping around Shelvin: how the place shapes the job

Shelvin is about 59 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal. 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. We install whatever has been specified, to the product’s tested detail.

For a building such as Church of St Martin, new heating or data runs are the usual reason penetrations need sealing. Offices at parks like Barham Business Park (to the west of Shelvin) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. For a hotel such as Broome Park Hotel, 0.6 miles north-west of Shelvin, penetration seals are worth checking after any refit or services upgrade.

For managing agents and facilities managers

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

What sealant work can’t fix

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Approving the work on behalf of building control
  • Walls or floors that aren’t fire-resisting to begin with
  • Fire doors, dampers or other fire safety equipment

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

What we seal

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