Fire stopping in Caversham Heights, done properly

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. If you’re dealing with penetration schedules that need working through and fire-rated sealant that has cracked or shrunk back, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Caversham Heights tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Buildings in a smaller place such as Caversham Heights that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Should maintenance staff do it?

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Our process

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. Several jobs near Caversham Heights can be grouped on one trip. Mention the building’s opening times and we’ll work within them.

  1. First we go through the drawings, schedule or specification for the seals.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  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. 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.

What we need from you

  • Point out parking and an unloading spot
  • Move anything stored against the joints
  • Send any specification or drawings in advance

Surface by surface

Linear joints

Head-of-wall joints often have to absorb slab deflection. The specified product and backing for that movement are what goes in.

Small ducts

Some fire-rated sealant details cover small ducts. Larger or fire-rated ductwork typically needs a different solution set by the designer.

Quoting for work in Caversham Heights

These are the things that shape the price:

  • Phasing around occupants
  • How accessible the joints are
  • Removal of failed or old sealant
  • How much there is to seal

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

Sending details for a quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • Whether an asbestos survey exists
  • Anything awkward about access or site hours
  • The product your specification calls for
  • The postcode of the building

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or speak to us on 01277 525 020 or send photos by email if you’d rather talk the job through.

Compartments and services around Caversham Heights

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. At about 39 miles from central London, Caversham Heights is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls.

After the work

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Ask the designer to confirm details early on refits
  • Include service cupboards in routine inspections
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Foam or ordinary sealant is never a fire-seal repair

Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.

Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job; found late, it can be one of many.

Signs you need fire stopping in Caversham Heights

Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped, and the repair is often skipped.

Clients usually get in touch after noticing one or more of the following:

  • Improvised or mixed-product fire seals
  • Fire seals cut back for extra cables and never reinstated
  • Snag lists that include open service penetrations
  • Hidden openings found during inspections

Colleges such as The Chiltern College (0.9 miles east of Caversham Heights) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.
