Fire stopping in Mill Meads, done properly

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. Most enquiries involve open linear gaps along the top of fire-resisting walls and penetration schedules that need working through, across joints between fire-resisting walls and floors, pipe penetrations and small duct penetrations where the tested detail allows. One point of contact handles commercial sealant work in Mill Meads from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. Our part is installing the specified fire-rated sealant; tell us what records you need and we will confirm with the quote.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Honest limits

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:

  • Deciding what a wall or floor needs, which belongs to the designer
  • Construction that lacks the fire resistance the seal relies on
  • Plastic pipes whose detail calls for a collar or wrap

If you’re not sure, just call 01277 525 020 or email the details over and we’ll give you a straight answer.

Surfaces we seal

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

Common problems we fix in Mill Meads

Openings in fire-resisting walls typically appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.

Typical triggers for a call:

  • Old intumescent sealant that has split away
  • Penetration schedules that need working through
  • Fire seals cut back for extra cables and never reinstated
  • Expanding foam used as fire stopping

Colleges such as Onelab College (0.6 miles south-west of Mill Meads) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

Questions to ask before you book

  • How joint depth will be controlled
  • Do they follow the manufacturer’s priming guidance?
  • The named product and why it was chosen
  • Their plan for phasing and protecting the area

How to choose a sealant contractor

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Agree the fire-stopping specification before services go in
  • Record which product was used where
  • Foam or ordinary sealant is never a fire-seal repair
  • Put resealing into every M&E and fit-out package

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, so check the product data first.

Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job; found late, it can be one of many.

Compartment walls and floors in Mill Meads

With tenants changing and fit-outs following, London buildings see service routes altered again and again. We install fire-rated sealant where it is specified and work within the building manager’s permit system. 17 care or nursing homes sit less than 2 miles from Mill Meads. Where new services have gone through compartment walls in a care setting, the gaps need the specified product.

Campus buildings at universities such as Arden University Stratford Campus (to the north of Mill Meads) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. Shop fits in centres such as Manor Road Retail Park, 0.9 miles to the south-east of Mill Meads, can bring new services through fire-resisting walls between units, which then need the specified seal.

Mill Meads is about 1 mile south of Stratford, in Greater London. Across the E3 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 764 places in Greater London, large and small.

If you need fire stopping in E3, E15 and E14, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Among the streets we cover are Gay Road, Bruce Road and Edgar Road. Nearby places we also cover include Three Mills (1 mile north), Bromley-by-Bow (1 mile south-west), Old Ford (1 mile north-west), Bow (1 mile west) and Bow Common (1 mile south-west) for service penetrations.

Mill Meads: questions and answers

Can you work around term dates at a campus such as Arden University Stratford Campus?

Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Is Crescent Court Business Centre, near Mill Meads, within your area?

Yes, sites like Crescent Court Business Centre are within our area, along with the rest of Mill Meads. A few photographs and the unit address let us price the work.

Can you tell us what fire stopping our building needs?

No. The specification comes from your designer, fire engineer or building control. Our role is installing what they specify, to the product’s tested detail.

Will you sign off the seals for us?

No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. Our part is fitting the specified product to its tested detail.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Do the same rules apply to fire stopping in Scotland?

Our work covers Greater London, the South East and every Scottish council area. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance.

Do you offer coloured sealant?

That depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

For managing agents and facilities managers

If you look after buildings for someone else, 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.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Our process

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

What we need from you

  • Confirm the product named in the specification
  • Tell us what induction or permit system the site runs
  • Move anything stored against the joints

Quotes

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or email drawings and photos.

Doing it in-house

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.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
