Fire stopping in Englefield

Where services cross fire walls in Englefield

At about 43 miles from central London, Englefield is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product. Fire stopping of openings and penetrations in England falls under 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. We install whatever has been specified, to the product’s tested detail.

In a building such as Church of St Mark, any service penetration through a fire-resisting wall should be sealed to the specified detail. Hotels such as Old Lamb Hotel, 0.9 miles south-east of Englefield, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. For a site team at a college like Integration College, which lies east of Englefield, fire-rated sealing is best scheduled after the summer works.

Englefield is about 5 miles west of Reading, in West Berkshire. Anywhere in RG7, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. 140 places across West Berkshire fall within our area, Englefield among them.

Fire stopping in Englefield, done properly

No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and raise it with you if it falls outside. Most enquiries involve unsealed penetrations discovered above suspended ceilings and old intumescent sealant that has split away, across cable penetrations, joints between fire-resisting walls and floors and pipe penetrations. Whoever orders the work in Englefield, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Smaller places such as Englefield still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Our process

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Rural sites near Englefield may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  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. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Getting the site ready

  • Send your site hours and access windows
  • Point out any areas we must not close
  • Warn occupants and staff about the work

When something else is needed

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:

  • Writing the fire-stopping specification
  • Fire doors, dampers or other fire safety equipment
  • Approving the work on behalf of building control

Not sure which it is? You can phone 01277 525 020 or email drawings and photos and we will tell you honestly.

Joints and surfaces we work on

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

Questions we’re asked in Englefield

Can you work at a site such as Chiltern Enterprise Centre, by Englefield?

Yes. Our area takes in Englefield and its surroundings, with estates and business parks such as Chiltern Enterprise Centre included. To start, just give us a call on 01277 525 020 or email us with the unit, the joints involved and your access times.

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

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

How do I request a quote?

You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.

Can the building stay open while you work?

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 the sealant be colour-matched?

That depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

When to bring in a specialist

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Building owners, agents and FMs in Englefield

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

How the job changes by surface

Small ducts

We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.

Linear joints

Joints at the top of partitions may need to move as the slab above deflects. The specified product and backing for that movement are what goes in, along the full length of the run.

How the quote is worked out

We price every job individually. The things that drive the figure:

  • Distance, for remote addresses
  • Quantities, in metres or numbers
  • The size and state of each joint
  • Removal of failed or old sealant

A quote for service penetrations depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Sending details for a quote

To price the job accurately, we need to understand the site. Useful things to include:

  • Access details, including height
  • Photos of the joints, close up and from further back
  • Asbestos survey details if the building is older
  • Whether the building will be occupied during the work

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email a schedule or drawings.
