How a job runs

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For a job in Popeswood, the main thing is a clear picture of the work, so send photographs of each area. A fixed quote follows.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

What we need from you

  • Tell us which areas need to stay in use
  • Warn occupants and staff about the work
  • Point out parking and an unloading spot

About our fire stopping in Popeswood

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 and the results are classified to BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. The enquiries we see most involve improvised or mixed-product fire seals and penetration schedules that need working through, across joints between fire-resisting walls and floors, pipe penetrations and linear gaps at wall heads. Most enquiries from Popeswood start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

In places the size of Popeswood, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Owners, agents and contractors

Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Where services cross fire walls in Popeswood

Popeswood lies roughly 30 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. A good number of hotels sit less than 2 miles from Popeswood. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.

For a building such as Church of St Mark, new heating or data runs are the usual reason penetrations need sealing. For a hotel such as Fines Bayliwick Hotel, which lies south of Popeswood, penetration seals are worth checking after any refit or services upgrade.

Popeswood is about 2 miles north-west of Bracknell, in Bracknell Forest. Anywhere in RG42, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Across Bracknell Forest, 48 places are covered, Popeswood among them. There’s a separate page for Reading, roughly 9 miles from Popeswood.

Work on service penetrations is covered throughout RG42 and RG12. Among the streets we cover are Cain Road, Wood Lane and Park Lane. If your building is just outside Popeswood, we cover Farley Wood (1 mile south-east), Binfield (1 mile north), Temple Park (1 mile north-east), Amen Corner (1 mile south) and Priestwood (1 mile east). A short drive away, we cover Sandhurst (5 miles south), North Ascot (4 miles east), Forest Park (3 miles south-east), The Warren (3 miles south-east), College Town (5 miles south) and Little Sandhurst (5 miles south).

When to call us in Popeswood

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls.

It’s worth sending us details if you spot any of the following:

  • Unsealed penetrations discovered above suspended ceilings
  • Unsealed joints where partitions meet the slab
  • Unsealed openings around new pipes and cables
  • Non-fire-rated filler around services

For a unit at a site such as Longshot Lane Industrial Estate (0.6 miles south-east of Popeswood), new power or data runs between office and warehouse can breach a compartment wall.

What your quote should include

  • Whether their applicators hold CSCS cards
  • How joint depth will be controlled
  • Their pre-qualification and accreditations
  • How the joint faces will be prepared and primed

Choosing a commercial sealant contractor

Honest limits

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Walls or floors that aren’t fire-resisting to begin with
  • Signing off or certifying a building’s fire stopping
  • Large openings beyond what any sealant detail covers

Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we will tell you honestly.

Surfaces we seal

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

Different surfaces, different methods

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access to these areas is planned with you in advance along with any permits your site needs.

Plastic pipes

Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail.

Common questions from Popeswood clients

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

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 cover business parks and estates near Popeswood, such as Longshot Lane Industrial Estate?

Yes. We cover Popeswood and the area around it, including industrial estates, business parks and retail parks such as Longshot Lane Industrial Estate. A few photographs and the unit address let us price the work.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Can you work while the building is occupied?

Normally, yes. We phase the work so most of the building stays in use, with each area protected and signed.

How much does the work cost?

Each job is quoted on its own details. To get one, speak to us on 01277 525 020 or email drawings and photos.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If our installation fails in that time, we return and fix it.

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

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, which is what makes a joint last.
