Fire stopping for businesses in Rowfant

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

Fire stopping in Rowfant, done properly

Most of our fire stopping work happens after the building is up. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, and they are easy to forget. Those on your schedule are closed with the specified product. If you’re dealing with fire stopping installed outside its tested range and old intumescent sealant that has split away, we can help, on cable penetrations, pipe penetrations and small duct penetrations where the tested detail allows alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Rowfant is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places like Rowfant, 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 ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

FAQs: Rowfant

Do you cover business parks and estates near Rowfant, such as Rowfant Business Centre?

Yes. Our area takes in Rowfant and its surroundings, with estates and business parks such as Rowfant Business Centre included. To start, just call 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Would you work within a site like Langley Green Hospital?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you certify or sign off fire stopping?

No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. Our part is fitting the specified product to its tested detail, and any records you need can be confirmed with the quote.

What’s the quickest route to a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

Do you cover Rowfant?

Yes. Sites across Rowfant are covered.

Do you seal openings left by new services?

Yes, provided a specification covers them. Openings left by new services are among the most common jobs we see.

Are you fully insured?

Yes. We are fully insured, including public liability cover.

When to bring in a specialist

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Our process

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Rural sites near Rowfant may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. First we go through the drawings, schedule or specification for the seals.
  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. Mineral wool or other backing goes in wherever the detail asks.
  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.

What we need from you

  • Warn occupants and staff about the work
  • Tell us your opening times and when work is allowed
  • Tell us which areas need to stay in use

What sets the cost

These are the things that shape the price:

  • The product specified
  • Joint width, depth and condition
  • Site requirements such as inductions and permits
  • Quantities, in metres or numbers

Pricing service penetrations depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Before you send an enquiry

However big the job, these details speed things up:

  • The type of building and who uses it
  • Where the site is, with the postcode
  • A wide shot and a close-up of the area
  • When you need the work done

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, speak to us on 01277 525 020 or email us.

Surface by surface

Risers and ceiling voids

Service risers and the voids above ceilings are where openings collect. Access to these areas is planned with you in advance.

Plastic pipes

Plastic waste pipes through slabs come up often. The detail decides whether sealant alone is enough.

What sealant work can’t fix

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

  • Construction that lacks the fire resistance the seal relies on
  • Plastic pipes whose detail calls for a collar or wrap
  • Approving the work on behalf of building control

If in doubt, speak to us on 01277 525 020 or send photos by email and we’ll say what we think before you book.

What we seal

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

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Compartments and services around Rowfant

Central London is about 26 miles from Rowfant. Office refits around the commuter belt bring new cabling through fire-resisting walls. For England, the fire stopping of penetrations is dealt with in 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. Either way, we install the specified product to its tested detail.

Schools such as Turners Hill CofE Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. Older community buildings such as All Saints Parish Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification. On a site such as Rowfant Business Centre, which lies south of Rowfant, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.
