Fire stopping near Trotton

Fire stopping in Trotton

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. If you’re dealing with service penetrations left open after M&E works and snag lists that include open service penetrations, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Trotton, preparation and product choice get the time they need.

A job near Trotton is typically planned around one visit, with the specification and photos sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

After the work

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Check with the data sheet before painting over fire sealant
  • Get seals inspected before ceilings and boxing close
  • Put resealing into every M&E and fit-out package
  • Don’t let anyone top up a fire seal with the wrong product

Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.

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 installation follows the programme.

FAQs: Trotton

Is a hospital such as Midhurst Community Hospital somewhere you can work?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

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

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

Do you work in Trotton?

Yes. Trotton is in our area. To discuss a job, call the office on 01277 525 020 or send details through our quote form.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Does weather matter for sealant work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

How soon can the area be used again?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Signs you need fire stopping in Trotton

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in.

Common reasons buildings call us in:

  • Openings found when ceilings come down for a refit
  • Damaged fire seals in risers and voids
  • Unsealed joints where partitions meet the slab
  • Openings left by services added after handover

In a school such as Stedham Primary School, fire-rated sealant goes in around service penetrations where it is specified.

Our contractor checklist

Surface by surface

Cables and cable bundles

Single cables and small bundles are often within a fire-rated sealant’s tested detail. Bundle size, cable type and the space between cables all matter, so we check before sealing.

Drylining partitions

Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers first.

Our process

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, and each area is checked before we leave it. If others near Trotton need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  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

  • Let us know about inductions and permits
  • Tell staff and tenants when we’ll be in
  • Move anything stored against the joints

Ask for a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

How the quote is worked out

To price the job, we consider:

  • Quantities, in metres or numbers
  • Travel to remote or island sites
  • Specialist products, such as fire-rated or hygienic sealants
  • Site requirements such as inductions and permits

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What to include in your enquiry

Diagnosis starts before we arrive. Tell us:

  • Whether the building will be occupied during the work
  • The postcode of the building
  • Specification clauses that apply
  • Clear photos of the problem areas

The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or call the office on 01277 525 020 or email us if you’d rather talk the job through.

Compartment walls and floors in Trotton

Central London is about 46 miles from Trotton. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. What we install is set by the specification, and it goes in to the tested detail.

Older community buildings such as St George's Church that have been rewired or given new heating can have service gaps through walls worth checking against the specification. Tenant changes at parks like Midhurst Business Centre (2.5 miles east of Trotton) bring new data and services, and openings through fire-resisting walls need the specified seal.
