Fire stopping in Arborfield Garrison, done properly

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate and we’d rather say that up front. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. If you are dealing with fire-stopping items raised at inspection or handover and non-fire-rated filler around services, we can help, whatever the surface. One point of contact handles commercial sealant work in Arborfield Garrison from the first photos to the final walk-round, for single jobs and planned programmes alike.

Converted and extended buildings around places like Arborfield Garrison can mix old and new construction, so the wall or floor a service passes through isn’t always what the drawings assume. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Questions about Arborfield Garrison

Is a smaller place like Arborfield Garrison outside your area?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Arborfield Garrison?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Are you fully insured?

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

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Is the work guaranteed?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

What sets the cost

Before we quote, we look at:

  • Whether old sealant has to be cut out first
  • Which sealant the job calls for
  • Joint width, depth and condition
  • The total length or number of joints

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Details that help us quote

However big the job, the same details help:

  • A wide shot and a close-up of the area
  • Where the site is, with the postcode
  • Asbestos survey details if the building is older
  • Anything awkward about access or site hours

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Diagnose, treat, sign off

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself typically taking longer where risers, ceiling voids or occupied floors have to be worked through in sequence. For a site in Arborfield Garrison, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  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. Anything outside the detail is reported to you rather than sealed.

Getting the site ready

  • Share your working hours and any access restrictions
  • Point out parking and an unloading spot
  • Make sure the joints can be reached

Advice

Compartments and services around Arborfield Garrison

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. Arborfield Garrison lies roughly 36 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product.

Where a unit on an estate such as Hogwood Lane Industrial Estate (0.5 miles south-east of Arborfield Garrison), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. At a healthcare site like Wokingham Hospital (3 miles north-east of Arborfield Garrison), new services through compartment walls are a constant, and each needs the specified seal.

Surface by surface

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We follow your schedule area by area, and note anything we find that isn’t on it.

Plastic pipes

Plastic waste pipes through slabs come up often. The detail decides whether sealant alone is enough, and we’ll never swap a specified collar for sealant.

What sealant work can’t fix

Being straight saves everyone time. Fresh joints won’t solve:

  • Signing off or certifying a building’s fire stopping
  • Large openings beyond what any sealant detail covers
  • Fire risk assessments, a job for a competent assessor

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

What we seal

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

Leave it or put it right?

Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down and each detail can be checked as we go. For buildings in places like Arborfield Garrison, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Why us?

  • Over 20 years of commercial sealing
  • Health and safety: CHAS accredited
  • Failed material removed, not covered up
  • A fixed quote before work starts

Do you need fire stopping in Arborfield Garrison?

When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are the usual culprits.

What tends to prompt an enquiry:

  • Fire stopping installed outside its tested range
  • Expanding foam used as fire stopping
  • Openings left by services added after handover
  • Fire seals cut back for extra cables and never reinstated

For an estates team at a campus like University of Reading - Whiteknights Campus, 4.5 miles to the north-west of Arborfield Garrison, summer M&E works are usually followed by a round of penetration sealing.
