Fire stopping for businesses in Amen Corner

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Our process

We schedule the visit to fit the site hours and access windows you give us. 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 Amen Corner, the main thing is a clear picture of the work, so send photos of each area. You’ll then get a fixed price for the work.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  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.

Getting the site ready

  • Tell staff and tenants when we will be in
  • Arrange parking or a loading space
  • Tell us what induction or permit system the site runs

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

How we handle fire stopping in Amen Corner

No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. Most enquiries involve hidden openings found during inspections and snag lists that include open service penetrations, on joints between fire-resisting walls and floors, cable penetrations and small duct penetrations where the tested detail allows. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Amen Corner it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places like Amen Corner, many commercial buildings are conversions or extensions of older ones, 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.

A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or email a schedule or drawings and we will come back to it.

Common problems we fix in Amen Corner

Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it, so it has to come out.

What tends to prompt an enquiry:

  • Unsealed joints where partitions meet the slab
  • Non-fire-rated filler around services
  • Damaged fire seals in risers and voids
  • Fire stopping installed outside its tested range

Wherever services are added at a hospital such as Wokingham Hospital, 2.7 miles to the west of Amen Corner, the compartment line has to be made good with the specified product.

Questions to ask before you book

  • Whether primer will be used where the manufacturer specifies it
  • How they’ll work around occupants
  • Their pre-qualification and accreditations
  • Whether their applicators hold CSCS cards

Our contractor checklist

Questions we’re asked in Amen Corner

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

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Longshot Lane Industrial Estate, near Amen Corner, within your area?

Yes. Our area takes in Amen Corner and its surroundings, with estates and business parks such as Longshot Lane Industrial Estate included. A few photos and the unit address let us price the work.

What changes on 2 September 2029?

It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications, though transitional rules apply. Scotland follows its own Technical Handbook.

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Is fire stopping in Scotland covered by different guidance?

Scotland sets its own building regulations, with Technical Handbooks, and England uses Approved Document B. Either way, we install the specified sealant to its tested detail.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

What will the job cost?

Every job gets its own fixed quote. For yours, call the office on 01277 525 020 or email a schedule or drawings with a description of the work.

Leave it or put it right?

An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. In a smaller place such as Amen Corner, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Why us?

  • Fully insured, including public liability cover
  • CHAS accredited contractor
  • Work to your specification and the manufacturer’s guidance
  • Our applicators hold CSCS cards

Maintenance after handover

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Agree the fire-stopping specification before services go in
  • Treat an open penetration as a priority repair
  • Leave fire sealant to cure fully before covering it
  • Arrange inspection before areas are covered up

After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.

Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.

Where services cross fire walls in Amen Corner

At about 30 miles from central London, Amen Corner is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal. In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.

At a college such as Newbold College of Higher Education, which lies north of Amen Corner, checking penetration seals after summer M&E works is good practice. For a hotel such as Coppid Beech Hotel (under half a mile north-west of Amen Corner), penetration seals are worth checking after any refit or services upgrade.

What sets the cost

What shapes the price:

  • Working within restricted access windows
  • The size and state of each joint
  • The product specified
  • The total length or number of joints

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

What to include in your enquiry

A few photographs plus some basic facts will normally do. It helps to include:

  • Approximate linear metres or a joint schedule
  • Specification clauses that apply
  • Whether the building will be occupied during the work
  • Access details, including height

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • Fire doors, dampers or other fire safety equipment
  • Large openings beyond what any sealant detail covers
  • Construction that lacks the fire resistance the seal relies on

If in doubt, give us a call on 01277 525 020 or email us and we will say what we think.

Surfaces we seal

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