Fire stopping near Jealott's Hill

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

Fire stopping in Jealott's Hill, done properly

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. If you are dealing with damaged fire seals in risers and voids and openings left by services added after handover, we can put it right. Whoever orders the work in Jealott's Hill, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Rural conversions around Jealott's Hill can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

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. For work around Jealott's Hill, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Preparing the site

  • Confirm the product named in the specification
  • Let us know about inductions and permits
  • Tell staff and tenants when we will be in

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 any of the following:

  • Fire doors, dampers or other fire safety equipment
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Construction that lacks the fire resistance the seal relies on

Not sure which it is? You can speak to us on 01277 525 020 or email us and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

Cost factors for service penetrations

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • How accessible the joints are
  • Quantities, in metres or numbers
  • Site requirements such as inductions and permits
  • The product specified

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Sending details for a quote

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

  • Rough lengths or quantities, or drawings if you have them
  • Any specification or named product
  • The postcode of the building
  • Any dates the work must fit around

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Fire stopping in Jealott's Hill: the local picture

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail. At about 28 miles from central London, Jealott's Hill is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product.

Halls and meeting rooms at places like Church of St Michael and All Angels sometimes gain new services, and any compartment wall crossed needs the specified seal. Holiday works at schools like Garth Hill College often leave service openings to seal before pupils return.

Jealott's Hill is about 3 miles north of Bracknell, in Bracknell Forest. We send applicators to Jealott's Hill for service penetrations, handled exactly as we handle every other area. 48 places across Bracknell Forest fall within our area, including Jealott's Hill. There’s a separate page for Reading, about 10 miles away.

Work on service penetrations is covered throughout RG42, for business premises of every kind. We cover commercial and managed buildings on Gough's Barn Lane and Maidenhead Road and the roads nearby. We also cover Tickleback Row (1 mile south), Moss End (1 mile south), Hawthorn Hill (1 mile north-east), Nuptown (1 mile east) and Warfield (1 mile south-east) for service penetrations. A short drive away, we cover Bracknell (3 miles south), Sandhurst (7 miles south), North Ascot (4 miles south-east), Great Hollands (4 miles south), Forest Park (4 miles south) and The Warren (4 miles south).

Questions about Jealott's Hill

What happens to BS 476 references for fire stopping in Jealott's Hill?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Do you take on work at healthcare sites like Heatherwood Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Is colour matching possible?

It depends on the product. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Signs you need fire stopping in Jealott's Hill

Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position and has to be removed.

What tends to prompt an enquiry:

  • Fire sealant pulled out of the opening
  • Hidden openings found during inspections
  • Penetration schedules that need working through
  • Builders’ foam or ordinary silicone in compartment walls

Colleges such as Newbold College of Higher Education, 2.4 miles south-west of Jealott's Hill, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

Before you book anyone

  • The terms of the workmanship guarantee
  • Their public liability cover
  • Are they CHAS accredited or on Constructionline?
  • How the joint faces will be prepared and primed

How to choose a sealant contractor

Work for main contractors and building owners

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Jealott's Hill. Several sites can go on one quote, so there’s one set of paperwork to deal with.

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

General trades versus a specialist

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.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
